How the HP N1200-320 4Gb Network Storage Router works  
The network storage router is a device that translates the Fibre Channel Protocol (FCP) to and from the SCSI  
Protocol—transparently transferring commands, data, and status information—so that both the Fibre  
Channel (FC) and SCSI devices and hosts can communicate with each other. Interconnection is provided  
between two SCSI buses and one Fibre Channel Arbitrated Loop or Switched Fabric, making use of Fibre  
Channel’s ability to encapsulate SCSI protocol packets.  
Processing SCSI information  
The following section describes how the network storage router processes SCSI information when attached  
to FC hosts.  
1. A FC host issues a command, then encapsulates the command in the FC protocol and sends the packet  
to the network storage router.  
2. The network storage router receives the packet, interprets the FC information, and places the packet in  
buffer memory.  
3. The processor interprets the information and programs an internal SCSI controller to process the  
transaction.  
4. The SCSI controller sends the command to the SCSI device (target).  
5. The SCSI target interprets the command and executes it.  
6. Data flows between the FC host and SCSI target through payload buffers.  
7. Response information flows from the SCSI target back to the FC host.

Setting up serial port communications  
The network storage router is designed to communicate with a terminal or any operating system utilizing  
a terminal emulator. For example, most Windows® operating systems can use a terminal. Be sure the  
baud rate, data bits, stop bits, parity, and flow control are set correctly.  
To set up serial communications with the network storage router:  
1. Plug the serial cable into one of the host computer’s serial ports (COM1 or COM2), and then plug the  
other end of the serial cable into the network storage router’s serial port (see Figure 2 on page 9).  
2. Start the terminal emulator.  
3. Set the terminal emulator to use the appropriate COM port.  
4. Specify the following settings for the port:  
Baud Rate:  
9600, 19200, 38400, 57600, or 115200  
(Autobaud only recognizes these baud rates)  
Data Bits:  
Stop Bits:  
Parity:

None  
Flow Control:  
None or XON/XOFF  
NOTE: Before initially applying power to the network storage router, make sure all the SCSI devices are  
powered on first, and that they have finished performing individual self tests. This helps to ensure that  
device discovery works correctly.  
5. Apply power to the network storage router. The power-up process can take up to 90 seconds. Once  
complete, the main menu should be accessible.

Cabling the N1200-320 4Gb Network Storage Router  
NOTE: Refer to the HP StorageWorks MSL2024 or the MSL4048 Tape Library User and Service Guide for  
detailed tape library information.  
Interfaces and connections  
There are four types of interfaces to the network storage router:  
Fibre Channel  
SCSI  
3-pin serial port  
Ethernet  
The 3-pin serial and Ethernet ports are used for configuration and management of the network storage  
router.  
For convenience in configuring ports, key information is indicated on the back panel of the network  
storage router such as WWN name, WWP name, and Ethernet MAC ID (Physical Address).  
Fibre Channel connections  
Before connecting the network storage router to other devices, it is important to understand the  
configuration requirements of the environment to which it is connected.  
IMPORTANT: Failure to correctly configure a Fibre Channel device may impair the operation of the  
Storage Area Network (SAN) to which it is attached.  
Typical installations have the network storage router connected to a Switched Fabric environment. For an  
Arbitrated Loop, the unit can be directly attached to the Fibre Channel host bus adapter. In Fibre Channel  
switched environments, the switch is also directly attached to the network storage router.  
Both FC switches and hubs may allow for individual ports to be configured for different media types. The  
network storage router must be connected to the hub or switch port with the appropriate FC cabling for the  
media type in use on both the network storage router and the port to which it is connected.  
The network storage router supports various Fibre Channel media types through the use of external Small  
Form Factor Pluggable Transceivers (SFPs).  
Supported media type: Multi-Mode Fiber - 4.25 Gbit Dual LC connectors.  
To connect the network storage router to the Fibre Channel SAN:  
1. Locate the Fibre Channel port on the network storage router (see Figure 2 on page 9).  
2. Remove the rubber protector from the SFP.  
3. With the network storage router powered off, connect the router into the Fibre Channel environment  
using the appropriate cabling. The FC optical connector on the network storage router is keyed. Be sure  
to insert the cable connectors in the proper orientation.

SCSI connection  
CAUTION: SCSI ports on the network storage router are not hot-pluggable. Power off the network  
storage router whenever connecting/disconnecting the SCSI cables.  
The network storage router can support Fast/Ultra320 Narrow/Wide SCSI, depending on the specific  
configuration. The network storage router is factory configured to support LVD/Single-Ended buses. Two  
VHDCI 68-pin D-shell, P-type connectors are available, allowing the unit to be attached at the end of up to  
two SCSI buses. The network storage router must always be installed at the end of SCSI buses.  
The network storage router supplies termination power (TERMPWR) to each SCSI bus. An internal  
self-resetting fuse in the TERMPWR resets after a fault is cleared.  
CAUTION: Do not plug HVD devices to an LVD/SE bus. Failure to follow this caution may result in severe  
damage to equipment.  
To connect the network storage router to a SCSI bus:  
1. Power off the network storage router.  
2. Power off the SCSI devices on this bus.  
3. Connect a SCSI cable to one of the SCSI connectors on the router. The network storage router should  
always be installed at the end of the SCSI bus.  
4. Make sure that the bus is terminated correctly. By default, the network storage router is automatically  
terminated. However, the device at the other end of the bus must also be terminated.  
Ethernet connection  
A 10/100BaseT Ethernet connection provides management and configuration access. The RJ-45  
connector on the unit can be directly connected to a standard 10/100BaseT Ethernet network.  
NOTE: You should change the pre-filled in settings if you disable DHCP, because while they are valid  
settings, a conflict occurs if more then one network storage router is on the network with these initial  
settings.  
Setting the IP network address is recommended, but not required, in order to configure the network  
storage router from this port. The IP network address can be manually assigned or dynamically assigned  
(using DHCP). The default network configuration is DHCP, but if DHCP is turned off, the initial value for  
the IP address is 1.1.1.1, the Subnet is 255.255.255.0, and the Gateway is 0.0.0.0.  
Depending on the network environment, you may be able to temporarily use the IP address of 1.1.1.1 to  
configure the network storage router. For more about the IP network address, refer to ”Network  
Ethernet capabilities include Telnet support for configuration and management and FTP support for other  
management capabilities.

Serial port connection  
The 3-pin connector on the network storage router provides a serial port that is compatible with RS-232  
signaling levels. The network storage router is designed to communicate with a terminal or any operating  
system using a terminal emulator. The baud rate, data bits, stop bits, parity, and flow control of both the  
network storage router and the host system must use the same settings. The Autobaud feature described  
below provides an effective method to set the baud rate of the network storage router and host system.  
Autobaud feature  
The Autobaud feature automatically configures the baud rate on the network storage router. Once you set  
the baud rate in the terminal emulator, wait until the network storage router completes the Power-On Self  
Test (POST) and then the firmware initialization process. This can take up to 90 seconds, during which  
time the POST and initialization information may or may not be visible on the terminal or terminal  
emulator. After this process has completed, you can press the Enter key slowly seven or eight times (or just  
type shift-z) and the network storage router automatically detects the baud rate being used by the  
serial port. The baud rate is then saved in the network storage router’s configuration and is retained  
through future power cycles.  
NOTE: Pressing the Enter key before the POST has completed is of no benefit to the Autobaud feature.  
Wait at least 90 seconds until both the POST and the firmware Initialization processes have completed  
before pressing the Enter key.  
NOTE: If there is no response using the Enter key, press the space bar slowly seven or eight times, and  
then press the Enter key slowly seven or eight times.  
The baud rate used by the terminal or terminal emulator must be 9600, 19200, 38400, 57600, or  
115200 for the Autobaud feature to recognize it. The network storage router does not function properly  
at any other baud rate.

3 Device management  
To provide connectivity between hosts and devices, it is necessary for the network storage router to be  
recognized with an address on the connected Fibre Channel network.  
SCSI bus configuration  
The network storage router provides the capability to reset SCSI buses during the network storage router  
boot cycle. This allows the devices on a SCSI bus to be set to a known state. Configuration provides for  
the SCSI bus reset feature to be enabled or disabled.  
The network storage router negotiates for the maximum values for transfer rates and bandwidth on a SCSI  
bus. If an attached SCSI device does not allow the full rates, the network storage router uses the best rate  
it can negotiate for that device. Negotiation is on a device specific basis, so the unit can support a mix of  
SCSI device types on the same SCSI bus.  
FC port configuration  
By default, the configuration of the FC port on the network storage router is set to N_Port mode. For more  
information, see the Fibre Channel Configuration sections in ”N1200-320 4Gb Network Storage Router  
FC arbitrated loop addressing  
On a Fibre Channel Arbitrated Loop, each device appears as an Arbitrated Loop Physical Address  
(AL_PA). To obtain an AL_PA, two addressing methods, called soft and hard addressing, can be used by  
the network storage router. Soft addressing is the default setting. For hard addressing, the user specifies  
the AL_PA of the network storage router.  
Soft addressing  
When acquiring a soft address, the network storage router acquires the first available loop address,  
starting from address 01 and moving up the list of available AL_PAs in the chart from 01 to EF. In this  
mode, the network storage router obtains an available address automatically and then participates on the  
FC loop, as long as there is at least one address available on the loop connected to the network storage  
router. Fibre Channel supports up to 126 devices on an Arbitrated Loop.  
Hard addressing  
When acquiring a hard address, the network storage router attempts to acquire the AL_PA value specified  
by the user in the configuration settings. If the desired address is not available at loop initialization time,  
the network storage router comes up on the FC loop using an available soft address. This allows both the  
loop and the unit to continue to operate. An example of this scenario would be when another device on  
the Arbitrated Loop has acquired the same address as that configured on the network storage router.  
Hard addressing is recommended for FC Arbitrated Loop environments where it is important that the FC  
device addresses do not change. Device address changes can affect the mapping represented by the host  
operating system to the application, and have adverse effects. An example of this would be a tape library  
installation, where the application configuration requires fixed device identification for proper operation.  
Hard addressing ensures that the device identification to the application remains constant.  
FC switched fabric addressing  
When connected to a Fibre Channel switch, the network storage router is identified to the switch as a  
unique device by the factory programmed World Wide Name (WWN) and the World Wide Port Names  
(WWPN), which are derived from the WWN.

Discovery  
Discovery is a feature that makes it easy to display attached FC and SCSI target devices and have them  
mapped automatically on the host side for the connected bus/port.  
There are two discovery methods available—Manual Discovery and Auto Discovery. Auto Discovery can  
be set to occur after either reboot events (when the card reboots) or link-up events (for instance, when  
cables are attached or a hub is rebooted). Discovery can also be turned off by setting the network storage  
router to Manual Discovery Only. The default setting for FC Discovery is Manual Discovery.  
For specific information on Discovery settings, see the Fibre Channel configuration and SCSI  
Host bus adapter configuration  
A host system using a Fibre Channel Host Bus Adapter (HBA) typically maps devices into the existing  
device mapping scheme used by the host operating system. Refer to the HBA manual for the mapping  
table.  
Mapping usually involves pairing FC AL_PAs to SCSI target addresses. The HBA claims enough SCSI bus  
entries to allow for 125 FC targets to map to SCSI bus:Target entries. This is usually done by a fixed  
mapping of AL_PA to Bus:Target. In such a configuration, the network storage router corresponds to a  
Bus:Target identifier, with the SCSI devices attached to the network storage router appearing as logical  
units (LUNs). Operating systems can extend the available SCSI limit of 15 targets per bus. Although this is  
not an issue for the operating system or most applications, there are cases where older applications can  
have expectations about what are valid SCSI IDs, and not correctly handle certain mappings. In  
particular, applications have been seen to exhibit difficulties addressing target IDs greater than 15 (e.g.  
16 and up). This problem can be resolved by configuring the network storage router to use hard  
addressing, and setting the AL_PA used by the unit to a value that the HBA will map to an ID with a value  
less than 16.  
For example, depending on the FC HBA, if the hard AL_PA selection is 1, the network storage router  
address is 1. If the selection is 125, the network storage router address is 0xEF. Some FC HBAs configure  
differently, so verify the AL_PA by reviewing the documentation for the HBA.  
Logical unit management  
Because SAN resources can be shared, multiple hosts can have access to the same devices on the SAN.  
To prevent conflicts, the network storage router provides the means to restrict access and only allow hosts  
to find and access selected devices. Simple LUN masking can restrict access, but many times this leaves  
gaps in the list of LUNs presented to a host, since devices are always associated with fixed LUNs. The  
network storage router, however, provides controlled access to devices by use of LUN management,  
which goes beyond simple LUN masking.  
LUN Management is the ability to present different hosts with different views of the devices accessed  
through the network storage router. For example, one FC host may see three disk LUNs and a tape LUN at  
LUNs 0 to 3 when it performs discovery on the network storage router. Another FC host may only discover  
a tape LUN at LUN 0. Not only can the administrator control which devices a host may access, but also  
which LUNs are used to access these devices.  
LUN Management is accomplished by allowing the administrator to configure multiple maps, each of  
which may present a different view of the devices behind the network storage router. Each host accessing  
the network storage router can be associated with a specific map.  
For a host connected to an FC port, a map is a table of LUNs where each entry in the table is either empty  
or contains device address information needed to route commands to the appropriate device.  
The FC port on the network storage router has a set of maps which include user defined maps and a few  
special predefined maps.  
There are currently four special predefined maps: Indexed, Auto Assigned, SCC, and Port 0 device maps.  
Until a user configures the network storage router otherwise, the default map setting is Indexed.  
24 Device management  
Download from Www.Somanuals.com. All Manuals Search And Download.  
           
The Indexed map is initially empty and can be modified by the user, however, this is not  
recommended.  
The Auto Assigned map is built dynamically, and contains all the devices found during discovery. This  
map changes automatically any time the discovery process finds a change in the devices attached to  
the network storage router. This map can be displayed, but cannot be modified directly by the user.  
The SCC map is only available on the FC port and contains a single entry. LUN 0 is an network  
storage router LUN, and access to devices behind the controller is handled by using SCC logical unit  
addressing.  
When a host sends a command to the network storage router, the network storage router selects which  
map to use, based on the ID of the host sending the command. For FC ports, the host ID is the World  
Wide Name. For SCSI buses, the host ID is the initiator ID (0 - 15). When a host is unknown to the  
network storage router, or is not attached to a specific map, the network storage router uses the default  
setting for mapping. The default setting for each port can be set to Auto-assigned, Indexed, or SCC  
(which applies to the FC port only) by the user.

4 N1200-320 4Gb Network Storage Router  
management  
The HP N1200-320 4Gb Network Storage Router can be managed over the following user interfaces:  
Over the serial port via a terminal or a terminal emulation utility (see ”Setting up serial port  
Over Ethernet via a Telnet utility or an HTTP-based interface called Visual Manager. Additionally, FTP  
support provides additional management functionality (see ”Visual manager user interface” on  
Before attempting to configure the network storage router, a basic understanding of Fibre Channel and  
SCSI devices is recommended.  
NOTE: For information on SCSI standards, refer to publications from the X3T10 committee of ANSI  
(American National Standards Institute). For information on Fibre Channel standards, refer to publications  
from the X3T11 committee of ANSI. For those who are interested in purchasing approved American  
National Standards and Technical Reports, you can contact ANSI at (212) 642-4900.  
Configuration methods  
The network storage router can be configured over the serial port via a terminal or terminal emulation  
utility, over Ethernet via a Telnet utility or Web browser. FTP is also supported on Ethernet.  
Serial port management access  
The serial port allows for configuration of device characteristics from an attached terminal or terminal  
NOTE: A Serial connection cannot be made if a Telnet session (discussed later) is already open. If a user  
attempts to open a serial connection while a Telnet session is already open, the following message  
appears over the serial interface:  
System in use via Telnet. Shell restarted.  
The serial interface resumes working when the Telnet session closes.  
Out-of-band Ethernet management access  
DHCP is enabled by default. The first time you use the network storage router, use the serial interface to  
identify the network settings that were assigned from the DHCP server, or to set a new static setting.  
When DHCP is disabled, the pre-filled in values are IP address 1.1.1.1, a subnet mask of 255.255.255.0,  
and a gateway address of 0.0.0.0. HP recommends that at a minimum, the IP address should be changed.  
CAUTION: HP strongly recommends not having two network storage routers using the pre-filled in static IP  
address on the same network, as this causes a conflict.  
When setting the IP address for the network storage router, there are two options:  
The first option is to enter a fixed, or permanent IP address for the network storage router.  
The second option is to enable DHCP on the network storage router, so that a DHCP server (on the  
Ethernet network used by the network storage router) can assign a dynamic IP address to the network  
storage router.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
         
Your DHCP server may also allow you to set up an extended lease reservation for an IP address, by  
providing the server with the Ethernet MAC address of the network storage router. This configures the  
DHCP server to always provide the same IP address to the network storage router. This setup can be  
useful for remote management of the network storage router via Telnet. Because the method of setting up  
a lease reservation varies depending on the DHCP server being used, HP recommends that you contact  
your Network Administrator for assistance.  
For more information about enabling DHCP on the network storage router, see ”Enabling DHCP on the HP  
Command Line Interface  
The network storage router is capable of holding Telnet sessions for configuration purposes. Access to the  
configuration menus via the serial port will be disabled when a Telnet session is connected. To open a  
Telnet session, the IP address of the network storage router and a Telnet client utility are required.  
NOTE: Rebooting the network storage router closes the Telnet session. After the network storage router  
reboots and completes POST, the user must restart or re-open the Telnet session.  
NOTE: Resetting to factory defaults from the Telnet interface does not affect Ethernet activity. User  
configured values for the IP address, gateway, and subnet mask are retained after the network storage  
router reboots. User name and password are not retained.  
NOTE: The network storage router supports only one Telnet session at a time.  
From most Windows systems, users can start a Telnet session from the DOS (or Command) prompt using  
the following steps:  
1. From the Windows Start menu, open the DOS (or Command) prompt window.  
2. At the ‘>’ prompt, enter the following command  
TELNET<IP address>  
where <IP address> is the IP address of the network storage router. This starts a Telnet session  
window for the network storage router.  
3. Enter rootfor the default user name and passwordfor the default password. HP recommends that  
you change the user name and password as soon as possible.  
4. Access configuration options in the same way used for the serial interface.  
5. To exit the Telnet session, select the Disconnect option from your Telnet client utility. In most Telnet  
utilities, this option is available as a menu item. If working from the Command Prompt in Windows,  
simply close the window to end the session.

Visual manager  
The network storage router allows any standard Internet Web browser to view and change the network  
storage router’s configuration with the Visual Manager interface. Information is dynamically generated in  
an HTML format by the network storage router, so that Web browsers can access it.  
To access Visual Manager, enter the IP address of the network storage router into the Address field of a  
Web browser. Or, you can enter a URL using a host name defined by the user—for instance,  
http://HPN1200-3204Gb (but the user must define the host name on the DNS server first for this to work).  
To make changes to network storage router settings, use standard keyboard and mouse controls to input  
information, and then select the Submit button to send the changes to the network storage router.  
A user name and password are required before any changes can be submitted. The default user name is  
root and the default password is password. HP recommends that you change the user name and  
password as soon as possible (see ”User name and password” on page 38).  
Other than dynamic mapping changes, any other changes will not take effect until the next time the  
network storage router reboots. You can force the network storage router to reboot by selecting the  
Reboot option.  
For more information about the Visual Manager interface, refer to ”Visual manager access” on page 31.  
NOTE: For the VM interface’s dynamic display of the network storage router configuration to be  
presented properly, use version 6.2 or later of Netscape’s browser on non-Solaris platforms, or Netscape  
version 6.2.3 for Solaris platforms. If using Internet Explorer, use revision 6.0 or later.  
FTP  
The network storage router includes support of File Transfer Protocol (FTP) for updating firmware, saving  
trace buffers, and backing up/restoring of configuration settings. FTP functionality is described in more  
detail in ”Using the Command Line Interface” on page 59. There is also an FTP Utility available within  
Visual Manager (VM) that is described in ”FTP utility access” on page 51.  
Inband SCSI-3 commands  
The network storage router supports a set of SCSI-3 commands that can be received as FCP commands  
over the Fibre Channel ports. When using these commands, they must be sent to a tape LUN or network  
storage router LUN of the network storage router. For more information, see ”Inband SCSI-3 commands”

NOTE: To use the DHCP feature, a DHCP server must be operational on the Ethernet network. If the DHCP  
feature is used when there is not a DHCP server, the standard for DHCP requires the network storage router  
to wait three minutes for a response from a DHCP server before timing out.  
Some DHCP servers allow an extended lease reservation to be set up for an IP address by providing  
the server with the Ethernet MAC address. The DHCP server always provides the same IP address to  
the network storage router. This setup can be useful for remote management of the network storage  
router via Telnet or VM. Because the method of setting up an extended lease reservation varies,  
depending on the DHCP server being used. Contact the Network Administrator for assistance.

Download from Www.Somanuals.com. All Manuals Search And Download.  
         
While the network storage router’s current, previous, and last assert trace data does provide a complete  
summary of events in a chronological fashion, SCSI Command Tracking adds the ability to filter the trace  
data to show only the information related to the processing of specific SCSI commands.  
SCSI Command Tracking can be toggled to ON or OFF. When toggled ON and submitted, all SCSI  
commands received or transmitted to or from the network storage router are then logged in the  
SCSI Commands section shown on this screen. When set to OFF (and submitted), no SCSI commands  
are logged.  
Previous entries for SCSI Command Tracking can also be cleared. Toggling the clear option to the ON  
position and selecting the Submit button clears all previous entries.  
The settings for the Host/Device ID Table are used to filter the trace data such that a sub-set of the total  
logged information is displayed under the SCSI Commands section. Logged data can be defined  
according to the Protocol (FC, Other, or ALL), Type (Device, Host, or ALL), and Value (ID or ALL). For the  
ID, this can be a specific FC LUN or Switch ID (S_ID) or some other specific value. Selecting the Submit  
button activates the settings for Protocol, Type, and Value.

6 Using the Command Line Interface  
This chapter describes specific configuration options available from the perspective of the Command Line  
Interface (CLI). For an overview of using the other configuration methods available, see ”N1200-320  
The network storage router allows the user to access many configuration settings through the Command  
Line Interface. Among these settings are:  
Serial, Ethernet, and fibre port configuration  
Fibre LUN mapping  
Assigning LUN maps to hosts  
Trace level settings  
All of the above settings may be changed and saved.  
NOTE: Unless otherwise indicated, configuration changes take effect when the system next powers on or  
reboots.  
Power-up messages  
When the HP N1200-320 4Gb Network Storage Router powers on, a series of power-up messages  
appear on the terminal or terminal emulation program for the serial port or the Telnet utility for Telnet  
sessions.  
A series of power-up self tests are performed as the network storage router starts (which can take up to 90  
seconds), and messages related to these tests are visible from the serial port. If completed successfully, the  
main menu appears, as shown in Figure 37.  
NOTE: The illustrations in this chapter use Xs to represent numeric values for certain data fields, such as  
the product release version and the revision of firmware.  
NOTE: For the serial port, if you do not see messages over the Command Line Interface, you may need to  
re-check your computer’s serial port settings.

Select 7 to toggle the DHCP setting. This setting enables/disables support for Dynamic Configuration  
Protocol. The default setting is enabled. When enabled, the network storage router retrieves a  
dynamic IP address from a DHCP server located on the Ethernet network that the network storage  
router is connected to.  
If DHCP is disabled and then enabled, it is necessary to save the current configuration and reboot the  
network storage router before an IP address can be requested from the DHCP server. Use the following  
four steps:  
a. Select X Return to previous menu.  
b. Select A Save Configuration.  
c. Select X Return to previous menu.  
d. Select 4 Reboot.  
After the network storage router finishes rebooting, the Main menu appears on the serial interface. For  
Telnet, a new session needs to be opened to continue configuring the network storage router. DHCP  
status can be verified from the Ethernet Configuration menu where DHCP Configuration is indicated as  
Enabled, if DHCP has been successfully activated. Note that the IP address may also appear different  
than the former non-DHCP IP address.  
NOTE: To use the DHCP feature, a DHCP server must be operational on the Ethernet network used by the  
network storage router. If the DHCP feature is used when there is no DHCP server, the standard for DHCP  
requires that the network storage router wait three minutes for a response from a DHCP server before  
timing out.  
Your DHCP server may allow you to set up a extended lease reservation for an IP address by providing  
the server with the Ethernet MAC address of the network storage router. This sets the DHCP server to  
always provide the same IP address to the network storage router. This setup can be useful for remote  
management of the network storage router via Telnet or Visual Manager. Because the method of setting  
up a lease reservation varies depending on the DHCP server being used, HP recommends that you  
contact your Network Administrator for assistance.  
Select 8 to change security settings, including the user name and password. User names and  
passwords should be unique and kept confidential and HP recommends using a combination of letters  
and numbers when creating user names and passwords.

Select 3 to change the Toggle Port Mode between Auto Sense - Soft AL_PA, N_Port, and Auto Sense -  
Hard AL_PA. The default setting is N_Port mode. In this mode, the FC port tries coming up as a fabric  
port. If the network storage router is on a loop and N_Port mode is selected, an error in communication  
may occur. In Autosense - Soft AL_PA mode, the network storage router FC port tries to come up as a  
loop, and if not successful, then tries to come up as a fabric. If the port comes up as a loop, it  
determines whether it’s on a private or public loop. If Auto Sense - Hard AL_PA is selected, a unique  
one-byte valid value (derived from an Arbitrated Loop Topology as defined in ANSI specification  
FC_AL 4.5) is used for the Fibre Channel configuration. When configuring the Fibre Channel AL_PA,  
the network storage router presents a list of loop addresses along with the corresponding AL_PA. From  
here, the user can select the loop address desired.  
Select 4 to set the Hard AL_PA Value by entering a node number from the AL_PA lookup table that  
appears when this option is selected. For more information, see ”Arbitrated Loop Node number to  
Select 5 to toggle the Discovery Mode among the following options:  
Auto Discovery on Reboot Events  
Auto Discovery on Link Up Events  
Manual Discovery Only  
IMPORTANT: HP recommends that you only use the Manual Discovery Only setting.  
Discovery Mode determines how the network storage router discovers a new FC devices.  
Auto Discovery allows the network storage router to automatically discover all Fibre Channel devices  
when the network storage router reboots.  
Reboot Events discovers both the ports and the devices behind the ports.  
Link-up Events discovers both the ports and the devices behind the ports for the first link-up event  
(which is the first reboot of the network storage router). Subsequent link-up events only discover the  
ports and not the devices behind the ports.  
Manual Discovery is the default selection and sets discovery of new devices to only occur after the user  
selects the Refresh Device Display option from the Display Attached Fibre Channel Devices menu,  
located under Main menu > System Utilities > System Statistics > Display Fibre Channel Protocol Status  
> Display Attached Fibre Channel Devices > Refresh Device Display.  
Select 6 to toggle Buffered Tape Writes to enabled or disabled. Buffered Tape Writes is an option  
designed to enhance system performance. By returning status on consecutive write commands prior to  
the tape device receiving data, Buffered Tape Writes remove the latency of waiting for responses from  
the tape device. In the event that data does not transfer correctly for any reason, the network storage  
router returns a check condition on a subsequent command.  
NOTE: The default setting is enabled. If the application requires confirmation of individual blocks being  
written to the medium, such as audit trail tapes or log tapes, this option should be disabled.  
Select 7 to change the Tape Backup Queue Depth. Select a value from 0 through 10.  
Select 8 to change the Default Map Value for the current port. This can be Indexed, Auto-assigned, or  
SCC. The default setting is Indexed. The FC Auto-assigned map contains all the SCSI devices that are  
attached to the network storage router.  
NOTE: When a new initiator contacts the network storage router through the selected port, it accesses the  
devices that are in this map by default.  
Select 9 to edit the FC override settings.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Following are descriptions for each of the override settings:  
NOTE: Normally, override settings should not be changed except when directed to do so by an  
authorized HP technician.  
• Select 1 to toggle the Hi-Sup Bit between SET and CLEAR. The default setting is CLEAR. This option  
should be toggled to SET when the server uses the Hi-Sup bit to scan for FC LUNs greater than  
eight.  
NOTE: Hi-Sup Bit is only set in an Active Fabric LUN which needs to be mapped as the first device (FC  
LUN 00).  
• Select 2 to toggle the Force FCP Response Code between OFF and ON for support of  
Compaq-specific HBAs #223180-B21 and #120186-001. The default setting is OFF.  
• Select 3 to toggle the Initiator/Target Bit Setting in PRLI between INITIATOR Bit Set, TARGET Bit Set,  
INITIATOR & TARGET Bits Set, and INITIATOR & TARGET Bits CLEAR. This should be configured to  
one of the options for SET on both network storage routers/routers when using the network storage  
router in an network storage router-to-router configuration (a configuration where at least one  
network storage router/router appears as a target to at least one other network storage  
router/router that appears as an initiator). The default setting is INITIATOR & TARGET Bits SET.  
• Select 4 to toggle the Initiator/Target Bit Setting in PRLI_ACC between INITIATOR Bit Set, TARGET  
Bit Set, INITIATOR & TARGET Bits Set, and INITIATOR & TARGET Bits CLEAR. This should be  
configured to one of the options for SET on both network storage router/routers when using the  
network storage router in an network storage router-to-router configuration (a configuration where at  
least one network storage router/router appears as a target to at least one other network storage  
router/router that appears as an initiator). The default setting is TARGET BIT SET.  
• Select 5 to toggle FC Confirm Setting in PRLI_ACC between FC CONFIRM SET and FC CONFIRM  
CLEAR. The default setting is FC CONFIRM SET. This option should be toggled to FC CONFIRM  
SET when the server is using QLogic HBAs.  
• Select 6 to access the Target Reset Mode menu. The default setting is setting ALTERNATE.  
Following are descriptions for each of the settings:  
• Select 1 to use a normal SCSI bus reset code to recover from a bus problem.  
• Select 2 to uses a progressive SCSI bus recovery mechanism that first attempts to recover the bus  
by attempting a target reset and, if this fails, then trying the bus reset.  
• Select 7 to toggle Force FLOGI in Private Loop between Disabled and Enabled. The default setting is  
Disabled. FLOGI Fabric Login is a process by which a node makes a logical connection to a fabric  
switch. This setting should be used to connect the attached Fibre Channel devices as private loop  
devices for certain switched fabric environments.  
Select A from the Fibre Channel Configuration menu to toggle the port speed between 1, 2, and 4

Device mapping  
This option allows the user to manipulate maps and associate a selected host with a particular map. Each  
physical port/bus on the system has at least an Indexed map and an Auto Assigned map. In addition,  
there is a SCC Map and a Port 0 Device Map on FCP ports. Each map has a unique name and map ID.  
You can rename all maps, except for Indexed, Auto Assigned, and SCC. The map that is set to be current  
must always contain valid information, since many of the operations on the map menu are executed  
against this map.

Select 1 from the Device Mapping Main menu to display all the maps defined by the system for the  
current protocol/port, and to choose one of the maps from the list to make it a current map. The map  
selected from this list is the one used by the network storage router to direct data to the appropriate  
targets and initiators.  
NOTE: Because the entire list of maps may not fit on one screen, select N or P to go back and forth  
between screens displaying more maps. Select X to return to the Device Mapping Main menu.  
Enter the number from the column on the left side of the table to select a map and make it Current. For  
example, entering 3 from the picture above would select the map named SCC Map on Fibre Channel  
Port 0 and make it a Current map.  
Select 2 from the Device Mapping Main menu to display the content of the current map. This option  
displays all the entries in the map. Information in the local part of the address (left) depends on the type  
of protocol for which the map is defined. The specific device address information depends on the  
protocol/port where the device resides. Mapping a device to the same port where it resides is not  
allowed. (that is, you can not map a disk on FCP Port 0 to an address on FCP Port 0.)

NOTE: Because the entire list of maps may not fit on one screen, select N or P to go back and forth  
between screens displaying more maps. Select X to return to the Device Mapping Main menu.  
Select 3 from the Device Mapping Main menu to create a new map. This option allows adding a new  
map for the current protocol/port or bus. Once the map is created, it becomes the current map.  
Select 4 from the Device Mapping Main Menu to delete current map. The screen asks for confirmation  
before deleting the map. After the map has been deleted, the default map for the current port becomes  
the current map. Maps with names Indexed, Auto Assigned or SCC Map may not be removed.  
Select 5 from the Device Mapping Main menu to edit current map. This option displays the Map Edit  
menu and allows user to edit the name of the map, change content of the map, clear, and fill the map.  
Editing an Auto Assigned or SCC Map is not allowed.  
NOTE: Enter the number of one of the available selections, or enter X to exit to the Device Mapping Main  
menu.  
• Select 1 from the Map Edit menu to edit the name of the current map. The name of the Indexed map  
may not be changed. Map name also cannot be left empty.  
• Select 2 from the Map Edit menu to edit entries in the current map. This screen allows the user to  
navigate up and down the map entries and create or remove entries. Device lists are also available  
to the user to make it easier to identify the device to be mapped. Mapping device to its native  
port/bus is not allowed. The information needed to create entries is protocol/port dependent.  
NOTE: Control of the editing process is done with simple single letter commands. Select N and P to scroll  
up and down the map entries. Select X to return to the Map Edit menu. Select A to add a new entry to the  
map or D to delete an already existing entry in the map. Select R to remove the gaps in the map.  
NOTE: SCSI devices attached to a Fibre Channel port must be mapped as sequential FC LUNs starting at  
LUN number 00. Skipping LUN numbers is not recommended when mapping FC LUNs because FC  
Discovery stops the discovery process whenever an empty LUN position is found.  
Adding an entry  
To add a new entry, the user must enter the desired Index. If the selected Index is already present in the  
map, the user is asked to confirm the override or enter different address information. Next, the operator is  
prompted for the protocol and port at which a device selection list is generated. (Devices may not be  
mapped to their native port).  
The following is an example of adding an entry for an FCP map:  
Figure 46 Adding an FCP port entry  
Enter desired Index > 0  
Select Protocol (0 - SCSI, 1 - AF, X=Cancel) > 0  
Select SCSI Port: Port# = ? (0-1,X=Cancel) > 1  
NOTE: If the operator selects a device with LUN ‘-‘, all LUNs for this Target are added to the map.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
NOTE: Hi-Sup Bit is only set in an Active Fabric LUN which needs to be mapped as the first device (FC  
LUN 00).  
Select a number from the left column Num to add a device to the map. Selecting a device where LUN=’-’  
adds all LUNS for this target. If the selected device is already mapped, an error message appears to warn  
the user about adding a duplicate device. N and P controls allow scrolling up and down the device list. X  
brings the user back to the Edit Map Entries display table.  
Creating an entry  
The user can create an empty map, or use an existing map to pre-enter devices that are not yet online. To  
perform this operation, the user has to know all the essential information about the device. A series of  
questions are asked to guide the user through the process. The questions vary based on the current map  
protocol.  
The user is asked to:  
Select the LUN address for a device,  
The protocol/port on which device it resides,  
The Name for the device (which can be left empty),  
And the type of device

NOTE: If the device being added is a SCSI device, the user is also asked to enter Target ID and LUN ID  
for the device. Target ID must already be defined in the SCSI Configuration. Otherwise, adding a device is  
not permitted.  
NOTE: Select MEDIUM_CHGR_DEVICE for the library or robot controller.  
NOTE: When creating a device that does not exist, it will be displayed with Down status.

Remove gaps  
NOTE: SCSI devices attached to a Fibre Channel port must be mapped as sequential FC LUNs starting at  
LUN number 00. Skipping LUN numbers is not recommended when mapping FC LUNs because FC  
Discovery stops the discovery process whenever an empty LUN position is found.  
This option removes any incremental gaps in the sequence of LUNs listed in the table.  
Deleting an entry  
The user selects a LUN ID.  
Figure 48 Deleting an entry  
Select LUN to delete (X=Cancel, D=DeleteMulitple) > 0  
Are you sure you want to delete LUN 0? (Y=Confirm, X=Cancel) > y  
Select D to delete multiple LUNs:  
NOTE: When deleting multiple LUNs, the user can list the LUNs to delete in a comma or space delimited  
format.  
Select 3 from the Map Edit menu to clear (that is, remove all entries from) the current map. The user is  
prompted for confirmation.  
Select 4 from the Map Edit menu to fill the current map. This selection scans the device list and appends  
all unmapped devices at the end of the current map. Devices marked as DOWN are not mapped. After  
this operation completes, the Edit Map Entries screen appears.  
Select 6 from the Device Mapping Main menu to clone current map. This option allows the user to  
make an exact copy of an already existing map complete with all entries. Cloning of Auto Assigned or  
SCC Map is not allowed. The new map must have a unique map ID and name. Once cloning is  
complete, the newly created map becomes current map. The purpose of this option is to create a base  
for a new map that is similar to an already existing map.  
Select 7 from the Device Mapping Main menu to edit the host list for the current map. The current map  
can be associated with hosts available in the host list on the same port where the map is defined.  
Initially all hosts are associated with an Indexed map. These are built at runtime hosts. They cannot be  
edited or deleted; their name cannot be changed.

Select 9 from the Device Mapping menu to activate port mapping changes.  
CAUTION: Before activating any port mapping changes, HP strongly recommends that the user verifies  
there are not any command or data operations occurring in conjunction with devices affected by the  
mapping changes. For example, deleting a LUN or device from a map may disrupt I/O transfers with that  
device. It is the user’s responsibility to ensure that no operations are negatively impacted due to the  
activation of mapping changes.  
NOTE: All current mapping settings take effect immediately. If another management interface has made  
unsaved mapping changes, those changes are lost. Current mapping settings are also not visible in other  
interfaces until the network storage router is rebooted.  
NOTE: If the Activate Port Mapping Changes option is not selected, the mapping changes do not take  
effect until the network storage router is rebooted.

Download a new revision of the firmware  
When this option is selected, a confirmation message appears to verify the selection. If a response of Y  
(yes) is given to the confirmation message, current network storage router activities are interrupted while  
the unit begins accepting the new firmware from the serial port.  
To download firmware using a terminal or terminal emulator connected to the serial port of the network  
storage router:  
1. From the Main menu, select the Download a New Revision of the Firmware option to start the  
download procedure.  
2. When you confirm you want to download, the network storage router starts the download process.  
3. Use the Transfer > Send File option in the terminal emulator utility.  
4. Select the location of the firmware. Use the Browse button, if you need help finding it.  
5. The download transfer protocol should use 1K XMODEM, if the terminal emulator supports it.  
Otherwise, use just XMODEM as the transfer protocol.  
6. Press the Send button. The firmware begins to download to the network storage router.  
When the download process is complete, the system verifies that the firmware image was successfully  
written to the FLASH memory and then reboots the network storage router. Upon reboot, the network  
storage router detects that there is a newly downloaded firmware image, copies that image to the boot  
sector of the FLASH, and then boots with that image. At that point, the network storage router is using the  
new firmware.

7 Using the FTP interface  
This chapter describes specific management options available from the FTP interface. For an overview of  
using the other management interfaces available, see ”N1200-320 4Gb Network Storage Router  
Backup/restore configuration settings  
The network storage router supports backup and restore of configuration settings over FTP. This allows  
users to maintain multiple setting configurations externally from the network storage router and to be able  
to restore any of the configurations as needed. When backing up, configurations are saved from flash to  
a binary file.  
Configuration backup procedure  
1. Connect the network storage router to the Ethernet network used by your computer.  
2. Start your FTP program using the network storage router’s IP address:  
ftp <IP address>  
IMPORTANT: The network settings set to use DHCP need to be set to default. If the IP address is not  
known, use the serial interface to obtain the network settings. See ”Setting up serial port communications”  
NOTE: You may also need to specify the directory location on your computer or network where your FTP  
program will store the backup file.  
3. Enter the user name and password. The default values for user name and password are rootfor the  
user name and passwordfor the password.  
4. Specify binary mode:  
bin  
5. Specify the filename (.cfgfile) with the getcommand:  
get filename.cfg  
(where “filename.cfg” can be any name for the configuration file.)  
The file will transfer to the current directory specified on your computer’s FTP utility. If running FTP from  
a DOS or Linux command line, the destination directory can be set using the lcd command (ex. lcd  
c:\myCfg).  
NOTE: World Wide Name (WWN) values and Ethernet physical address (MAC address) values will not  
be saved. Because user defined values for these settings are not retained in the configuration backup file,  
they must be re-entered after the configuration is restored.  
Configuration restore procedure  
1. Connect the network storage router to the Ethernet network used by your computer.  
2. Start your FTP program using the network storage router’s IP address:  
ftp <IP address>  
IMPORTANT: The network settings set to use DHCP need to be set to default. If the IP address is not  
known, use the serial interface to obtain the network settings. See ”Setting up serial port communications”  
Download from Www.Somanuals.com. All Manuals Search And Download.  
               
NOTE: If the network storage router is to use a static IP address, the pre-filled in address when DHCP is  
disabled is 1.1.1.1 and should be changed to an address that is appropriate for the IP network it will  
reside on.  
3. Enter the user name and password. The default values for user name and password are rootfor the  
user name and passwordfor the password.  
4. Specify binary mode:  
bin  
5. Specify the configuration’s path and filename (.cfgfile) with the putcommand:  
put <path\filename.cfg>  
The file will transfer and the network storage router will reboot. The network storage router will then be  
using the configuration.  
NOTE: World Wide Name (WWN) values and Ethernet physical address (MAC address) values will  
revert to the factory default settings. Any user defined values for these settings are not retained and must  
be re-entered after a configuration is restored. See ”Configuration backup procedure” on page 91 for  
more information.  
NOTE: Confirm the new configuration by checking that the settings are correct.  
Get a copy of trace buffer or event log  
Using the following procedure, you can save copies of the trace buffers or event log over FTP.  
1. Connect the network storage router to the ethernet network used by your computer.  
2. Start your FTP program using the network storage router’s IP address:  
ftp <IP address>  
IMPORTANT: The network settings set to use DHCP need to be set to default. If the IP address is not  
known, use the serial interface to obtain the network settings. See ”Setting up serial port communications”  
NOTE: You may also need to specify the directory location on your computer or network where your FTP  
program will store the trace file.  
NOTE: If the network storage router is to use a static IP address, the pre-filled in address when DHCP is  
disabled is 1.1.1.1 and should be changed to an address that is appropriate for the IP network it will  
reside on.  
3. Enter the user name and password. The default values for user name and password are rootfor the  
user name and passwordfor the password.  
4. Specify Bin mode:  
bin  
5. Specify the filename (.txtfile) with the getcommand.  
• For the current trace buffer, use get curtrace.txt.  
• For the previous trace buffer, use get prvtrace.txt.  
• For the assert trace buffer, use get assertlog.txt.  
92 Using the FTP interface  
Download from Www.Somanuals.com. All Manuals Search And Download.

a DOS or Linux command line, the destination directory can be set using the lcd command (ex. lcd  
c:\myCfg).  
Updating firmware  
Using the following procedure, FTP can be used to update the network storage router firmware.  
1. Connect the network storage router to the Ethernet network used by your computer.  
2. Start your FTP program using the network storage router’s IP address:  
ftp <IP address>  
IMPORTANT: The network settings set to use DHCP need to be set to default. If the IP address is not  
known, use the serial interface to obtain the network settings. See ”Setting up serial port communications”  
NOTE: If the network storage router is to use a static IP address, the pre-filled in address when DHCP is  
disabled is 1.1.1.1 and should be changed to an address that is appropriate for the IP network it will  
reside on.  
3. Enter the user name and password. The default values for user name and password are rootfor the  
user name and passwordfor the password.  
4. Specify binary mode:  
bin

8 Troubleshooting  
Various problems can arise when configuring and using the HP N1200-320 4Gb Network Storage Router.  
This section is provided to help guide the user through some of the basic methods of identifying faults in the  
setup and configuration of the network storage router.  
Most problems are found in the initial installation. In general, it is wise to check all connections and review  
the configuration before proceeding with further trouble analysis. Simplify the installation if possible,  
reducing it to the most basic configuration, then adding elements one at a time and verifying the operation  
at each step.  
General troubleshooting  
What happens if the DHCP server cannot be contacted?  
Serial Interface: the following occurs over the serial line: the following text appears above the HP  
Systems Main menu within the terminal window, Attempting to contact DHCP server…” After about 3  
minutes, the following message appears, “Can’t renew DHCP boot lease.”  
Within Telnet: the user will see only a blank Telnet window which is not accessible. Instead of an IP  
address value displaying in upper left heading of Telnet window, “(None)” appears instead. Within  
half a minute, Telnet will produce a warning message stating “Connect Failed!”  
Within Visual Manager: the user will be able to submit a new Web page and reboot (as is typically the  
case). However, since the DHCP isn’t contacted, a new IP address will not be generated after reboot.  
Therefore, Visual Manager will no longer be useful since no IP address is available. The previous  
non-DHCP will not work either. Visual Manager will time out and provide a warning message to the  
user stating that “a connection with server could not be established.”  
In the above situations, perform the following:  
1. Check on the status of the DHCP server with your network administrator,  
2. Ensure the Ethernet link (LNK) light on the network storage router is green (and if not check that the  
Ethernet cable is securely connected).  
3. Check the configuration of the network storage router, including the gateway address, and assign  
values manually, if needed.  
If the above list all appear to be in order, but DHCP is still not working, attempt to reset the network  
storage router to factory defaults (any current configuration settings will be reset), reboot the network  
storage router, and then reconfigure the network storage router as desired. If problems persist, see  
Indicators  
The network storage router is equipped with LED indicators for monitoring overall unit status (see Figure 74  
on page 96). The LED functionality of the network storage router is detailed below:  
Power and Fault (PWR)—This indicator is a bi-color LED. When green, this indicator shows that power  
is currently active. Lack of power indication suggests that the unit is turned off, a problem with the  
power supplied to the unit, or an internal problem with the unit. When this indicator is amber, this  
indicator shows that the network storage router detects a fault condition. Faults can occur as a result of  
Power On Self Test (POST) failure or operational failures. It is normal for this indicator to flash on when  
the unit is powered up or reset. If the fault indicator stays lit, contact your product support  
representative.  
Fibre Channel (LNK/ACT)—When green, the LNK indicator signifies a good Fibre Channel link on the  
port. When green, the ACT indicator signifies Fibre Channel port activity. If the LNK indicator fails to  
light at all, or if the ACT indicator stays continually lit without corresponding activity on a FC device  
port, there may be a problem with the Fibre Channel configuration. Verify the Fibre Channel  
configuration.  
SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the  
number of the indicator. Activity should only occur briefly during power-up or configuration, and  
relatively often when the unit is transferring data. If an ACT indicator stays continually lit without  
Download from Www.Somanuals.com. All Manuals Search And Download.  
           
corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify  
the SCSI bus configuration.  
Ethernet (10/100)—The LNK should stay permanently lit to indicate an Ethernet link. The ACT indicator  
should flash to indicate activity. If either of these indicators fail to flicker, or stay continuously lit, there  
may be a problem with the network connection or configuration. Verify the network connection and  
configuration. The port must be connected to a Ethernet network to function properly.

Basic verification  
Serial port problems  
If you experience trouble communicating with the serial port, verify the configuration of the host terminal or  
terminal emulation program. The network storage router requires the baud rate to be set correctly: 8 data  
bits, 1 stop bit, and no parity. Flow control should be set to none or XON/XOFF, and may cause problems  
if set to hardware. Some terminal programs may not support baud rates higher than 19200, so a lower  
baud rate may be required. If problems persist, you may want to check the cabling or try a different host.  
Be sure the Scroll Lock key on the keyboard of the host computer is not enabled. If a valid Ethernet IP  
address is configured, serial configuration settings can also be set via telnet.  
Login problems  
In a switched fabric environment, if a login problem is experienced, or if the drives can not be seen,  
confirm that the port settings of the network storage router are set for auto-sense or for N-port. Using a  
hard ALPA setting with the N-port setting is not a valid configuration.  
Windows driver  
There are no actual device drivers required for the network storage router. When Windows prompts for a  
device driver, this situation occurs because the Active Fabric LUN of the network storage router is enabled.  
Solutions to this request for a driver include the following options:  
Disable Active Fabric (or the target LUN for the network storage router, in order to eliminate further  
Windows driver requests. You can also accept the Windows prompts and disable the device in the  
device manager.  
Optionally, an HP device driver installation file (called an INF file) is included on the User  
Documentation CD. The network storage router does not really need an actual driver, as the HBA in the  
host PC manages this. However, the included INF file does allow the Windows Device Manager to  
register the network storage router’s network storage router LUN as a system device. Thereafter, the  
Device Manager will no longer consider this network storage router LUN to be an unknown or “newly  
96 Troubleshooting  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                 
discovered” device every time there is a reboot. By using the included INF file, the user just needs to  
identify the network storage router to the Windows Device Manager only once.  
To install (or register) the network storage router to a connected host Windows PC, perform the following  
steps:  
1. Copy the INF file to the Windows PC which has the FC HBA to be connected to the network storage  
router. Typically, the appropriate location to copy the file is as follows:  
C:\WINNT\system32\  
NOTE: There must be a network storage router LUN set up on the network storage router so that the  
Windows operating system can discover it.  
2. When the network storage router FC Link LED indicates a good connection, the user can either reboot  
the PC or run the Windows Device Manager Scan for New Hardware function. Either action should  
result in the HBA issuing a SCSI Inquiry command, to which the network storage router replies with an  
ASCII Inquiry string.  
NOTE: Initially, the Windows Hardware Wizard uses this string to refer to the network storage router.  
After this discovery interaction occurs, the Hardware Wizard will prompt the user to install a device driver.  
3. Select the Wizard’s Search for Better Driver option and specify the folder containing the network  
storage router INF file. The Hardware Wizard will scan the specified folder for all INF files and will  
select the first INF file it finds with a device entry containing a matching hardware ID string.  
NOTE: The Hardware Wizard will copy the selected INF file, renaming it to OEM<#>.inf, where the # is  
some integer, and it will place the copied file into the C:\WINNT\inffolder. The Hardware Wizard will  
then compile the INF file to a .PNFfile with the same root filename and use its network storage router  
model entry information to install, or register, the newly discovered device.  
4. Reboot the host PC to complete the process, as prompted by the Hardware Wizard.  
Verify SCSI bus configuration  
Problems with SCSI bus configuration are common. Basic operation of a SCSI bus can be checked by  
using the configuration menu to view attached SCSI devices.  
Other conditions to look for include:  
Termination—Problems with termination can cause intermittent or hard failure. A SCSI bus must be  
terminated on both ends, and only both ends. Termination issues when both narrow and wide devices  
are on the same bus are common. Check to make sure that there are no loose terminators. All  
terminators should be firmly attached.  
Bus Type—The SE and LVD devices can be connected to the same SCSI bus; however, on power-up, if  
at least one SE device is detected, the LVD devices must convert to SE mode, and SE mode will be used.  
Only the LVD interface is being specified for the Fast/40 and higher rates.  
Device ID—Each device on a SCSI bus must have a unique ID. Also check the configured ID’s for the  
network storage router to verify these are not in use by other devices on the same SCSI bus.  
Cabling—Check SCSI cables to verify that they are functional. SCSI rules for total length, distance  
between devices, and stub length must be adhered to. Connections should also be checked and  
reseated if necessary. Ensure that the SCSI cables are Multimode or rated for the SCSI speed of the  
drive.  
SCSI Devices—Verify that the SCSI devices on a particular SCSI bus can be seen in the configuration  
menu of the network storage router. Select System Utilities > System Statistics > Parallel SCSI Protocol  
Status > Display Attached SCSI Devices > Display ALL Local Devices. If the network storage router can  
not see the devices, verify SCSI configuration, cabling, and termination.

Even if the SCSI devices are displayed, they are not accessible unless the mapping mode is  
auto-assigned or another non-empty map is used.  
Verify Fibre Channel connection  
If SCSI devices are recognized on the SCSI buses, but do not appear to the Fibre Channel host, it may be  
that the Fibre Channel link is not properly established. Most hubs and switches have link indicators,  
showing link status. When the network storage router is connected and the library is powered-on, this link  
indicator should show a good link (see ”Operation indicators” on page 10). If it does not, check the  
cabling and connections.  
As a means of verifying link integrity when connected to a functional host, disconnecting then reconnecting  
the Fibre Channel cable should cause momentary activity of this indicator as the link itself reinitializes. Also  
verify that the media type of the network storage router and attached hub, HBA, or switch are of  
corresponding types. When using optical media, verify that the attached device is using non-OFC type  
optical devices.  
Also, make sure that the network storage router is configured with the same speed as the device it is  
connected to, and that the host is assigned to a LUN map filled with the devices it should be able to  
communicate with.  
Verify SCSI devices in Windows NT  
If running FC-to-SCSI mapping mode, open the NT Control Panel, select SCSI Adapters, and double click  
on the FC HBA. The SCSI devices should be listed.  
If no devices are listed, verify the network storage router configuration, FC HBA configuration, and  
cabling.  
If devices are listed, verify FC HBA mapping mode or AL_PA addresses on the network storage router.  
Verify configuration  
A number of configuration changes may result in an invalid configuration. If you are in doubt about the  
configuration, restore the network storage router to the factory default configuration and proceed to  
configure the unit a step at a time, verifying the functionality of the configuration as changes are made.  
Verify mapping  
Verify that all desired devices have been discovered and mapped. If using Indexed or SCC mapping, try  
swapping to Auto-assigned to see if this solves the problem.  
NOTE: HP recommends that you DO NOT use Auto-Assigned long-term as it exposes the library and  
drives to the entire SAN. Instead, a custom map should be created with only the hosts that need to  
communicate with the library and the drives assigned to it.  
Verify devices  
It may be useful to connect the SCSI target devices you are attempting to use to the native SCSI interface to  
verify that the devices are functional. SCSI target devices can be connected to a host SCSI bus to verify  
they are functional.  
Verify host configuration  
In some cases, it may be that the FC host bus adapter or host device driver may not be working properly.  
Check the configuration of these elements. It may be useful to check the release notes for the driver  
provided to see if there are any specific issues or required configuration. It may also be useful to ensure  
that you are using a current version of the host bus adapter driver and firmware.

D Addressing, structures, and operations  
Fibre Channel and SCSI systems employ different methods of addressing devices. The inclusion of a  
network storage router requires that a method of translating device IDs be implemented so that each SCSI  
device is mapped to the appropriate Fibre Channel LUN. The SCSI buses establish bus connections  
between devices. Targets on a SCSI bus may internally address logical units. The addressing of a specific  
SCSI device is represented by the BUS:TARGET:LUN triplet.  
When a Fibre Channel initiator initializes on a loop, the host must first determine what devices exist on  
the loop. Device discovery is performed, and an FCP target device list is built. Each device is queried for  
FCP logical units. The logical units are the actual devices that the operating system will address. When an  
initiator addresses a logical unit, the LUN field used is consistent in form with the SCC defined fields. All  
current Fibre Channel host bus adapter drivers are consistent with these methods. The addressing used is  
the SCC Logical Unit Addressing and Peripheral Device Addressing methods, shown in Table 16 and  
Table 17. First level addressing is supported, so only the first 2 bytes of the 8-byte FCP LUN are used.

The data shown in Table 20 comes from the Fibre Channel Configuration Menu (setting the AL_PA value)  
on the network storage router. The user enters the node number (number to the left of the colon from  
Table 20) and the network storage router translates the node number into the corresponding AL_PA value  
(number to the right of the colon in Table 20).  
Auto Assigned addressing option  
The Auto Assigned option is similar to the Indexed addressing, but with the distinction that the table used  
is created through SCSI device discovery on power-up or reset, and not otherwise retained. As the unit  
performs device discovery on the SCSI bus, the Index table FCP LUN values are filled with adjacent FCP  
LUNs referencing each subsequent SCSI device. The host system will then detect every attached SCSI  
device without voids, allowing full device discovery to the host. This allows easy configuration in  
environments where SCSI device ordering is not important, and where hot plugging of SCSI devices will  
not occur. Configuration options provide for the SCSI discovery to be performed in order of bus, target, or  
LUN as desired for the specific environment.

Indexed addressing option  
Indexed Addressing allows for host bus adapter (HBA) drivers that only use Peripheral Device addressing  
to access SCSI devices attached to the network storage router. This is done by use of a table, which is  
indexed by sequential LUN values, indicating selected BUS:TARGET:LUN devices. It is not possible in this  
mode to address the network storage router as an network storage router unit directly. The table has the  
structure as shown in Table 21.  
The maximum size of the table is equal to the number of buses times the number of targets per bus, less  
one initiator ID per bus, times the number of LUNs per target.  
The index table can be manually edited. A method is also provided to perform SCSI device discovery,  
and fill the table in the order that SCSI devices are discovered on the SCSI buses.

SCC addressing option  
When an network storage router device is configured to use SCSI network storage router Commands  
(SCC) addressing, the unit is capable of responding as an network storage router device to the FCP  
Initiator, or routing the FCP request to a specified BUS:TARGET:LUN. When a request using the Peripheral  
Device addressing method is received (an FCP command with the LUN field with bits 7 and 6 of byte 0  
are set to 0), the unit routes the request to the internal processor, which acts on the command directly.  
When a request using the Logical Unit addressing method is received (bits 7 and 6 set to 10b), the  
request is routed to the BUS:TARGET:LUN as specified in the defined field.  
Host systems using SCC addressing will typically do initial device discovery using the Peripheral Device  
addressing method. On issuing an INQUIRY command to the network storage router, the host will receive  
the network storage router Inquiry data, indicating the device type as a network storage router device  
(Inquiry data indicates device type is 0xC). The host will then know, on this basis, that subsequent  
commands to network storage router attached devices will use the Logical Unit addressing method.  
The host can perform discovery by either walking through the BUS:TARGET:LUN values as would a  
standard SCSI driver, or by issuing a REPORT LUNS command. This command is sent to the network  
storage router (using the Peripheral Device addressing method), and the network storage router returns a  
table indicating attached devices. The host can then perform actions on these network storage router

attached devices directly without having to perform discovery by issuing commands through all possible  
combinations.

E Enabling DHCP on the HP N1200-320 4Gb  
Network Storage Router  
DHCP, or Dynamic Host Configuration Protocol, is an open industry standard that simplifies administering  
networks based on Transmission Control Protocol/Internet Protocol (TCP/IP). DHCP allows network  
resources to go farther by enabling a unique IP address to be assigned to a specific device (network  
storage router, client host, etc.) on a non-permanent, dynamic basis.  
DHCP makes network administration easier—the larger the network, the greater the benefit. DHCP  
accommodates larger networks because it can assign temporary IP addresses for a specified time interval.  
DHCP frees network administrators from having to configure each network storage router or host  
manually.  
Other benefits of a DHCP environment include:  
No additional address configuration is required for client hosts.  
IP addresses can be reused or leased for specific time periods.  
IP address assignment is better managed. For example, if the IP address for an network storage router  
in a network changes and 250 client computers have to be updated with the new address, you do not  
have to manually reconfigure every workstation.  
Without DHCP, permanent IP address configuration is the only option. This means a network  
administrator is required to manually configure a permanent IP address for each individual network  
storage router or client host. Permanent IP addresses require more network resources, but are useful when  
dealing with smaller LAN environments. Without dynamic address assignment, network storage routers  
and hosts have to be configured manually one by one. IP addresses must be managed to avoid duplicate  
use, and changes must be applied to clients by hand. Configuration information is not centralized, and it  
is difficult to get a view of all network storage router or host configurations.  
The use of TCP/IP and DHCP both contribute to networking and the growth of the Internet. TCP/IP uses  
open protocol standards that enable the forming of wide area networks (WANS). For each network  
storage router to identify itself on a TCP/IP network, it must be uniquely identified by the following  
information:  
1. An IP address: a 32-bit field composed of four octets (8-bit numbers from 0 through 255). Each  
address has decimal notation to separate octet numbers, such as 208.24.132.184.  
Your DHCP server may allow you to set up a lease reservation for an IP address by providing the  
server with the Ethernet MAC address of the network storage router. This sets the DHCP server to  
always provide the same IP address to the network storage router. This setup can be useful for remote  
management of the network storage router via Telnet or Visual Manager. Because the method of  
setting up a lease reservation varies depending on the DHCP server being used, it is recommended  
you contact your Network Administrator for assistance.  
2. A subnet mask: This indicates how the IP address is to be read. It also indicates how to separate the  
network identifying information from the network storage router identifying information so the IP  
address can be interpreted correctly. For example, if a subnet mask of 255.255.255.0 is applied for  
an address 10.85.189.24, it indicates that the unique network storage router address is 24, located  
on the 10.85.189 subnetwork.  
3. A default gateway: This is used to specify the address for the nearest network storage router that is  
used by the host device to forward addressed packets on to the network.  
These previous three options (IP address, subnet mask, and gateway) are necessary for effective DHCP.

Setting up DHCP over network storage router interfaces  
Network storage routers use three different interfaces which can be used to enable DHCP: Serial, Telnet,  
and VM. The following will describe how to enable and disable DHCP for each interface.  
NOTE: Located on the network storage router is a label that displays the unit’s Ethernet MAC Address. A  
network administrator can then use this MAC Address to set up a lease reservation on the DHCP server for  
the IP address of the network storage router. This effectively allows the network storage router to have a  
permanent IP address that is assigned by the DHCP server.  
Serial and Telnet interfaces  
When the user turns on the library, and thus the network storage router, the system reboots and displays  
the following Main menu on the terminal window:

Protocol and allows the network storage router to be assigned a dynamic IP address from a DHCP server  
located on the Ethernet network used by the network storage router.  
For descriptions of other menu selections, refer to ”N1200-320 4Gb Network Storage Router  
Once DHCP is enabled, it is necessary to save the current configuration and reboot the network storage  
router before DHCP will operate.  
NOTE: For the IP address, Subnet Mask, and IP Gateway address, it is okay to have null values prior to  
rebooting the network storage router. However, if these settings have null values after a reboot, then this  
indicates the DHCP Server was unable to acquire the information for that setting. See the note below for  
more information.  
Use the following steps to save the current settings and reboot the system:  
1. Select X) Return to previous menu.  
2. Select A) Save Configuration.  
3. Select X) Return to previous menu.  
4. Select 4) Reboot.  
After the network storage router finishes rebooting, the Main Menu will appear. DHCP status can be  
verified from the Ethernet Configuration Menu where DHCP Configuration is indicated as “Enabled” if

DHCP has been successfully activated. Note that the IP Address my also appear different than the former  
non-DHCP IP Address.  
NOTE: To use the DHCP feature, a DHCP server must be operational on the Ethernet network used by the  
network storage router. If the DHCP feature is used when there is no DHCP server, the standard for DHCP  
requires that the network storage router wait three minutes for a response from a DHCP server before  
timing out. During this period, the network storage router menus and functions will not be accessible.  
Special note regarding Ethernet IP, subnet mask, and gateway addresses  
Once DHCP is enabled, any “null” readings are acceptable for these 3 options before reboot. The  
Ethernet Configuration Menu will also not allow these 3 options to be changed while DHCP is enabled  
(since they are automatically configured by DHCP). Here’s an example of the “DHCP-enabled” menu:

Visual Manager  
To access the network storage router using the Visual Manager interface:  
1. Look up the current IP address within the Ethernet Configuration menu using the serial interface.  
2. Type the IP address in the Web browser without using “www” or “/” or any other characters or  
symbols.  
3. After entering the IP address, the user should see the Configuration Main menu. Click on the  
Configuration link. This will access the Configuration Menu containing CURRENT/NEW readings for  
DHCP (“Use DHCP”). The following 3 DHCP-relevant options are also listed:  
• Ethernet IP address,  
• Subnet mask, and  
• Gateway IP address.  
Tips for manipulating DHCP within Visual Manager  
1. To change the current state of DHCP, change its status to enabled or disabled, submit the change and  
then reboot.  
2. To reboot, click the Reboot link from the main menu, select Yes in the confirmation message, and then  
submit.  
3. The gateway address should have the same subnetwork (1st three bytes) as the IP address. For  
example, an IP address of 192.168.100.93 may have a gateway of 192.168.100.1. However, an  
unavailable gateway value appearing under the CURRENT section of the Configuration menu means  
the DHCP server was unable to get the gateway address. If this happens, contact the network  
administrator to make sure the DHCP server is providing this information, or manually change the  
gateway address yourself.  
Now you should be able to access the new IP address displayed within the Ethernet Configuration menu  
using Visual Manager.

An electrical connection at each end of the SCSI bus composed of a set of resistors (or possibly  
other components). Its function is to provide a pull-up for open collector drivers on the bus, and  
also impedance matching to prevent signal reflections at the ends of the cable.  
The SCSI bus requires termination at both ends of the bus. One end of the SCSI bus is  
terminated by the SCSI adapter’s internal termination. The other end should have a terminator  
placed on the SCSI connector on the last SCSI peripheral. If this device is not terminated, data  
errors may occur.  
topology  
The physical or logical layout of nodes on a network. FC topologies include Point-to-Point,  
FC-AL, and Fabric.
