Preface
The Overland Storage REO 9000 Disk-Based Backup-and-Recovery
Appliance takes the lag time, expense, and burden out of backing up
critical data and works seamlessly within current storage environments.
The REO Appliance performs faster than traditional disk-based storage
methods and serves as a shared network resource by utilizing high-
capacity disks, high-speed Ethernet and Internet SCSI (iSCSI)
connectivity, and unique software intelligence capability from Overland
Storage.
The REO Appliance comes with a standard software package called the
ProtectionPAC. The ProtectionPAC software contains all the basic
features that you need to configure your REO Appliance to work within
your network environment.
This document includes information that helps you set up the REO
Appliance, including system requirements, questions that you need to
answer before installing the product, and installation procedures.
Important: If you purchased multiple units, set up (attach and
configure) one unit at a time. The target names must be unique within
a network; that is, if you are using multiple appliances, you must
change the default target names.
Also, be aware that the keys are not interchangeable and Overland
strongly recommends that you make a backup copy of the files on the
keys before and after you configure them.

Reviewing REO 9000 Concepts
and Requirements
1
CHAPTER
The main steps involved in preparing to set up the REO Appliance
include:
Step 1 Understanding the concepts of iSCSI, Fibre Channel (FC), disk-to-disk-
to-tape (D2D2T) backup, redundant array of independent disks (RAID),
tape emulation, logical volume management (LVM), and how the REO
Appliance fits into the picture.
Step 2 Reviewing the requirements that your servers and network must meet to
ensure successful installation and operation of the REO Appliance.
Important Concepts to Understand
To understand the configuration of the backup network and how it fits
into the local-area network (LAN) or Fibre Channel (FC) storage-area
network (SAN), review the following sections.
Internet SCSI (iSCSI) Protocol
Internet SCSI (iSCSI) is a standard protocol for universal access to
shared storage devices over standard, Ethernet-based transmission
control protocol/Internet protocol (TCP/IP) networks. The connection-
oriented protocol transports SCSI commands, data, and status across an
page 163.
iSCSI Architecture
The iSCSI architecture is based on a client-server model. The client is a
host system that issues requests to read or write data. iSCSI refers to a
client as an initiator. The server is a resource that receives and executes
client requests. iSCSI refers to a server as a target.
File servers, which store the programs and data files shared by users,
normally play the role of server. With the REO Appliance, the application
and backup servers within your network act as clients or initiators and
the REO Appliance acts as a server or target. The initiators can either be
software drivers or iSCSI host bus adapters (HBAs) on the server that is
being backed up.

Fibre Channel (FC)
Instead of, or in addition to, using iSCSI and the TCP/IP protocol to
transmit information over a network, you also have the option of using a
SAN that makes use of the FC and Small Computer System Interface
(SCSI) protocols. The FC protocol uses two additional protocols to
communicate at the hardware level: Fibre Channel Arbitrated Loop (FC-
AL), which communicates with hubs, and Fibre Channel Switched (FC-
SW), which communicates with switches. The SCSI protocol provides the
communication link at the higher level, between the hardware and the
software.
You can use all three basic FC SAN topologies with the REO Appliance:
„ Point-to-point. This topology provides a direct connection between
two N_Ports.
„ Arbitrated loop. In an arbitrated loop, NL_Ports and FL_Ports are
daisy-chained with hubs, which means that only one device can send
data at a time.
„ Switched fabric. Switched fabric consists of one or more switches
that are interconnected, and multiple nodes connected to the switches.
The REO Appliance supports the following types of ports for FC:
Port Type Represents
Associated Topology
N_Port
Node Port
Connects point-to-point or to F_Port
NL_Port
Node Loop Port N_Ports that can connect to an arbitrated loop
FC uses strict naming conventions to support unique, 64-bit names for
the worldwide node name (WWNN) and the worldwide port name
(WWPN). These names are pre-assigned by the manufacturers of the
different hardware components used in an FC.

Disk-to-Disk-to-Tape (D2D2T) Backup Capabilities
The REO Appliance is a storage resource used by a single backup server
or shared by multiple backup servers using an Ethernet or FC network.
By using standard backup software, you can copy backup data that
resides on the REO Appliance to tape for long-term data retention.
The following illustration shows application servers sending backup data
over a 10/100 or Gigabit Ethernet (GbE) LAN to backup servers sharing
REO Appliance D2D storage over GbE or FC.

REO
Redundant Array of Independent Disks (RAID)
RAID provides convenient, low-cost, reliable storage by saving data on
more than one disk drive simultaneously. If one disk drive in a RAID 5
configuration becomes unavailable, the others continue to work in a
degraded state, thus avoiding downtime for users.
Note: Because RAID 5 is designed for data protection, you might see
performance degradation when compared to JBOD operations.
RAID allows you to group the individual disk drives on the REO
Appliance into logical disk drives of different sizes. You can configure
your REO Appliance to create two physical RAID volumes by selecting
either of the following RAID options:
„ RAID 0. This configuration uses striping, which provides enhanced
performance and volume-level capacity. It divides the data into blocks
and writes each block to a separate disk drive, which improves
performance by dispersing the input and output load. RAID 0 does not
provide data redundancy.
„ RAID 5. This configuration uses striping and distributed parity,
which provides a balance between performance and availability. In
addition to dividing the data into blocks as described for RAID 0, the
parity information is also striped across the disks. If one of the disk
drives fails, you can use the parity information to rebuild the lost data.
In addition to using either of the preceding RAID configurations, you can
also take advantage of logical volume management (LVM) and create
logical volumes from the data pool.
Important Concepts to Understand W 15

Overland Storage REO 9000 with ProtectionPAC Software
If you use a RAID 5 configuration, you can also set aside a disk drive for
each physical host (controller); that is, you can create a hot spare. These
disk drives remain in standby mode, and you can use them immediately
if another disk fails.
Tape Emulation
The ProtectionPAC software includes two tape emulation features, which
you can use to create virtual linear tape-open (LTO-2) tape devices that
provide 2-to-1 compression ratios with typical data sets (actual
performance might vary with application). When you use tape emulation,
the disk drives on the REO Appliance appear to your backup software as
LTO-2 tape drives, which simplifies the setup process while
simultaneously providing data compression and the attributes of backing
up data to disk.
Depending on the configuration that you use, you get a different number
of virtual LTO-2 devices. In the just-a-bunch-of-disks (JBOD)
configuration, you can have up to 24. If you use RAID 0 or 5 without
logical volumes, you can have four. If you use logical volumes with
RAID 0 or 5, you can create up to 64 virtual LTO-2 devices.
If you decide to use tape emulation, you also have the option of using
fixed-length (Tape) or dynamic-length (Dynamic Tape) devices. To take
advantage of the Dynamic Tape option, you must use logical volumes,
which is described in the next section. Using Dynamic Tape lets you
create devices that adjust to the size of individual backup jobs.
Logical Volume Management (LVM)
With LVM, you can combine the two physical RAID volumes into
multiple logical volumes (partitions) of different sizes and assign logical
unit numbers (LUNs) to represent the different volumes, or REO devices.
This feature lets you set up and assign devices to different systems
according to your needs and the configuration and type of storage
network that you use.
Using this feature in the ProtectionPAC software, you can create up to 64
LUNs, and you can reassign space allocation for disk or standard (not
dynamic) virtual tape devices, in 1 gigabyte (GB) increments, on the fly.
Reviewing Pre-Installation Requirements
Before attempting to operate the REO Appliance with your backup
servers, verify that your network meets the minimum requirements
specified in the following sections.
Important: If you purchased multiple units, set up (attach and
configure) one unit at a time. The target names must be unique within
a network; that is, if you are using multiple appliances, you must
change the default target names.
Also, be aware that the keys are not interchangeable and Overland
strongly recommends that you make a backup copy of the files on the
keys before and after you configure them.

Setup Guide
Network
For best results, Overland Storage strongly recommends that you use a
dedicated GbE network to share the storage resources on the REO
Appliance among multiple backup servers.
To ensure optimum performance, always use the appropriate patch
cables to connect the REO Appliance to the backup-server storage
network. To select the appropriate cables, use the following guidelines:
„ If you intend to use GbE, you must use Category 5E (or better) cables
for GbE connections. You can use either straight-through or cross-over
cables.
„ If you intend to connect the REO Appliance to a 100 BaseT network,
use CAT 5 (or better) shielded (screened) or unshielded 100-ohm
twisted-pair RJ-45 network cables. Also:
„ If you intend to connect the Management Port, which is a 10/100
port, to an application or backup server via a switch, you must use
a straight-through cable.
„ If you intend to connect the Management Port directly to your
application or backup server (without a switch), you must use a
cross-over cable.
„ The maximum length of cable for any Ethernet-based network
connection is 328 feet (100 meters).
Note: For smaller environments, you can attach the REO Appliance
directly to a single application or backup server by using standard
Category 5E cables without the use of a switch.
iSCSI Initiators
iSCSI initiators are required to communicate with the iSCSI targets
(REO Devices) on the REO Appliance. Each backup server that will
interface with the REO Appliance must be equipped with a software- or
hardware-based initiator. The REO Appliance supports any computing
platform with an available iSCSI initiator, either in software or using an
iSCSI HBA (it must be iSCSI draft 20/version 1.0).

Overland Storage REO 9000 with ProtectionPAC Software
Setting the SCSI Time-Out Value in Windows
Environments
If you intend to use your REO Appliance in a Windows environment, be
aware that there are certain operating conditions in which time-out
errors might occur. These errors usually result in the system reporting a
disk failure for the associated REO Appliance disk drive or drives. (These
errors might be reported as iSCSIPrt errors in the System Log of the
Event Viewer. Examples include an Event ID 9 [Target did not respond
in time for a SCSI request…] and Event ID 39 [Initiator sent a task
management command to reset the target…]. Other symptoms might
include “Lost Delayed Write Data” system error messages or similar
error messages related to the REO Appliance disk drives.)
The reason that these disk time-out errors can occur is because the
default I/O time-out value for Windows is 20 seconds, which is not
sufficient to support the default iSCSI protocol time-out value of 60
seconds. When you install and set up your REO Appliance, Overland
strongly recommends that you set this value to 60 seconds.
To set the time-out value to 60 seconds
1 On the Windows system, run regedit.
Warning: If you edit the registry incorrectly, you might cause serious
problems that require you to reinstall your operating system. Edit the
registry at your own risk. Prior to making any changes, refer to the
following Microsoft Knowledge Base article:
2 In HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Services\Disk, edit or add the TimeOutValue entry to set it to 60
seconds in decimal format ((0000003c in hexadecimal).
„ To edit the value for the TimeOutValue entry if it already exists,
double-click the entry, enter the new value, and click OK.
„ To add the TimeOutValue entry if it does not yet exist, right-click
anywhere in the list of values, and then click New > DWORD value.
Name the new value TimeOutValue, and then double-click it to edit
the setting.

2 Setting Up the REO 9000
CHAPTER
The main steps involved in setting up the REO Appliance include:
Step 1 Unpacking the REO Appliance, and reviewing safety guidelines.
Step 2 If you intend to position the REO Appliance in a rack, attaching the
required components.
Step 3 Connecting the REO Appliance to the management LAN.
Step 4 Connecting the REO Appliance to the application and backup servers,
SAN for the backup servers, or FC.
Step 5 Connecting external SCSI devices.
Step 6 Attaching the power cords.
Preparing the REO Appliance
Caution: Due to the weight of each rack-mounted unit when it is fully
extended, you should install units from the bottom up. Extending a
unit that has empty spaces beneath it might cause the rack to tip
forward or might cause personal injury. Overland Storage
recommends that two people support and slide the unit in the rack.
Vorsicht: Aufgrund des Gewichtes eines Gerätes, welches für den
Einbau in ein Rack gedacht ist, empfehlen wir Ihnen, dieses von unten
nach oben in das Rack zu installieren. Wenn Sie ein Gerät aus dem
Rack heraus ziehen, könnte es Ihnen entgleiten und so zu
Verletzungen führen. Wir empfehlen den Ein- und Ausbau des
Gerätes durch zwei Personen.

1 Unpack the REO Appliance.
The shipping container contains the following:
„ Overland Storage appliance chassis
„ Depending on which version of the product that you purchased, either
12 or 24 disk carriers and disk drives
„ Power cords (U.S.) (Approved cord sets shall be used in countries
outside North America.)
„ Appliance face-plate
„ REO SoftKey
„ Rack-mount hardware
„ Documentation CD-ROM and poster
2 Review the following guidelines prior to positioning the REO Appliance
physically within your network.
„ Make sure that the REO Appliance is accessible.
„ Make sure there is unrestricted air flow around the unit and through
the vents in the sides and rear of the case.
„ Route external cables so that they can be connected easily without
blocking air vents or impeding air flow.
„ Protect the REO Appliance from extreme temperature and humidity.
Overland Storage recommends that you install the REO Appliance in
a clean, air-conditioned environment where water and moisture
cannot enter the case of the REO Appliance. Keep the air as free from
dust as possible.
„ Protect the REO Appliance from physical shock and vibration.
„ Make sure that the inlet air temperature within the rack remains
below the specified limit of 95°F (35°C).
„ Keep the REO Appliance and cabling away from sources of electrical
noise such as elevator shafts, stereo speakers, microwave ovens, air
conditioning units, and even telephones. Electromagnetic fields can
interfere with the signals on copper cabling and introduce errors,
therefore slowing down the network.

Connecting External Devices to the REO Appliance
The REO Appliance includes two Ultra320 SCSI ports, which support
SCSI devices such as medium changers and tape drives. You can use a
chain formation to assign up to 15 SCSI IDs to each port.
To connect SCSI devices to your REO Appliance
X On the rear of the REO Appliance, attach the applicable devices to the
SCSI ports.
You must use an external 68-pin SCSI cable that includes a male connect
with thumbscrews to connect a device to the port. (This cable is not
included with the REO Appliance.)
SCSI port 0
SCSI port 1
Attaching the Power Cords
1 Attach all four power cords to the REO Appliance.
2 Plug the power cords in to an AC power source (do not turn the power on).
Important: You must connect and use all four power cords; if one of the
cords is disconnected or malfunctioning, the REO Appliance beeps
repeatedly until the situation is resolved. Overland Storage
recommends that you use separate power mains for the power sources.
If you are not using Dynamic Host Configuration Protocol (DHCP), it
is critical to the configuration process that you refrain from enabling
power to the REO Appliance before completing the configuration steps
specified in the next chapter.
Power problems can be the cause of serious failures and downtime in
your network. Ensure that the power input to your system is clean and
free from sags and surges to avoid unforeseen network outages. Overland
Storage strongly recommends that you install power conditioning and an
adequately rated uninterruptible power supply (UPS), especially in areas
prone to blackouts, power dips, and electrical storms.
The REO Appliance is intended to be grounded. Ensure it is connected to
earth ground during normal use. Installing proper grounding helps to
avoid damage from lightning and power surges.

Using the REO SoftKey to Start
the REO 9000

CHAPTER
The main steps involved in using the key to start the REO Appliance
include:
Step 1 Making a backup copy of the key.
Step 2 If your network does not use DHCP, manually editing the configuration
and network files on the key.
Step 3 Connecting the key to the REO Appliance.
Understanding What the REO SoftKey Is
The REO SoftKey is a removable USB disk drive on a key ring. It
contains the software and settings required for configuring the REO
Appliance and must be inserted in the REO Appliance whenever you
restart it (because the REO Appliance uses a Linux-based OS, the key is
formatted using the virtual file allocation table [VFAT]). You can also use
the REO SoftKey to download and install updates when they become
available.
Important: If you purchased multiple units, note that the keys are not
interchangeable
The simplest configuration can be achieved when your LAN uses
DHCP on its own subnetwork (subnet). If your LAN does not use
DHCP, you must manually edit the configuration file located on the
REO SoftKey before continuing.

7 Continue the configuration process by configuring the GbE data ports as
described in the next section.
Configuring the GbE Data Ports
The GbE data ports are used for block-level data transport between your
backup servers and the REO Appliance. Data Port 1 and Data Port 2 are
fully interchangeable prior to configuration.
Important: Remember that the Management Port is on the LAN (a
10/100 network); use Data Port 1 and Data Port 2 on separate subnets
of the backup network. Data Port 1 and Data Port 2 each require an
available static IP address within their respective subnets. If you want
to manage the REO Appliance from the same port, use the GbE (Data
Port 1 or 2) IP address. Entering this IP address in your browser
displays the REO Appliance software console.
If you have one or two backup servers, you can connect each one directly
to one of the data ports on the REO Appliance. The backup servers must
have a GbE port. If you have more than two backup servers, you must
make these connections through a GbE switch.
To configure the GbE ports
1 In the right pane, scroll down below the Management Port section to
locate the Data Port 1 and Data Port 2 sections.
2 In the Data Port 1 section, enter the following:
„ IP Address. Using dotted decimal notation, enter an available static
IP address that falls within the Data Port 1 subnet. An example of an
address is: 192.168.1.4.
„ Subnet Mask. Using dotted decimal notation, enter the subnet
address. An example of an address is: 255.255.0.0.
Tip: If you change one of these settings, such as the IP Address, you
might need to reconnect to the server via your Web browser.

Configuring E-mail Alerts
The REO Appliance continuously monitors its performance and routinely
checks for disk failures. If you use the messaging option, an e-mail is sent
whenever the Status of a volume on the REO Device Summary page
becomes anything other than Up (for example, changes to
REBUILDING).
Tip: You can also use the ALARM MESSAGES section on the Physical
Volume Management page to see more information. The messages
(also known as asynchronous event notifications) that appear on this
page display additional information about each disk that might not be
displayed in an alert e-mail.
You can specify whether the REO Appliance should send an alert once or
repeat the message until the issue is resolved. Each alert that is sent
reports the status of all volumes on the REO Appliance. If you configure
the option to use an Alert Frequency of five minutes or more, the alerts
will be numbered.
If your mail server is able to send e-mail messages outside the company,
you can also set up messaging to notify Overland Storage Technical
Support automatically whenever a critical error occurs.

Involved in the Backup Process
The main steps involved in configuring the backup servers include:
Step 1 Mapping the REO Appliance to a drive letter to simplify access to the
console and other installation and management tools.
Step 2 Installing software client drivers or storage adapters for iSCSI or FC
access.
Mapping a Network Drive to the REO Appliance
(Windows Only)
To access the components used for installation and configuration of the
REO Appliance, you must map a network drive from the system to a
folder located on the REO Appliance.
1 Make sure that the REO Appliance is still powered on and that the REO
SoftKey is still inserted in a USB port.
3 Repeat these steps for each system that will access storage on the REO
Appliance.
Establishing Communication
If you are using iSCSI connectivity, iSCSI initiators are required to
communicate with the iSCSI targets (REO Devices) on the REO
Appliance. Each backup server that uses the REO Appliance must be
equipped with a software initiator, such as the Microsoft iSCSI Software
Initiator, or an IP storage HBA, such as the Intel PRO/1000 T IP Storage
Adapter.
Note: You do not need TOE-equipped (Transmission Control Protocol
[TCP] Offload Engine) or special iSCSI-capable GbE HBAs to work
with software initiators. Any standard Network Interface Card (NIC)
can serve as an iSCSI network interface device; however, Overland
Storage strongly recommends that you use GbE for enhanced
performance.
If you are using FC connectivity, make sure that the applicable FC
initiator is installed.

CHAPTER
The main steps involved in switching from one configuration to another
or creating logical volumes include:
Step 1 Selecting the applicable configuration.
Step 2 Creating the desired number of logical volumes, and setting their size.
Using the Default Volume Setup
The REO Appliance uses a default volume configuration of RAID 5 with
logical volumes. To use this configuration, you must create the logical
volumes.
X To use the default configuration and create logical volumes, proceed to
Changing the Volume Configuration
You can use the Volume Setup feature in the console to select a different
RAID configuration or to select the JBOD configuration.
Important: Be aware that the process of changing the volume
configuration takes time for the RAID 5 configurations while the
arrays are initialized. After you select the new configuration and the
initialization process begins, you can use the REO Appliance, but
performance will be impacted. Overland Storage strongly recommends
that you wait until the Status on the Physical Volume Management
page is OK (not INITIALIZING) before using a volume. (Switching to
a RAID 0 or JBOD configuration usually requires less than 10
minutes.)

5 After waiting approximately five minutes, log on to the console, and then
Selecting a RAID Configuration
The REO Appliance supports RAID 0 and RAID 5. You can only select
one configuration; that is you cannot set up one volume to use RAID 0
and set up another to use RAID 5.
Important: Because the process of changing the volume configuration
takes time if you select a RAID 5 option, Overland Storage
recommends that you make your selection and let the process run
overnight. (Switching to a RAID 0 or JBOD configuration usually
requires less than 10 minutes.)
In a RAID configuration, how the volumes are arranged depends on
whether you are using an appliance that contains 12 physical disks or 24,
and it depends on whether those disks are 250 GB or 400 GB in size.
The appliance also contains two physical hosts (controllers). If you are
using 12 physical disks, they are all assigned to the first host; if you are
using 24 disks, the second set of disks is assigned to the second host.
If you select a RAID 5 option, you will also have the option of creating a
hot-spare disk drive for each physical host (controller) after you click
Submit. (These disk drives remain in standby mode, so that you can use
them immediately if another disk fails.)

The following describes how the volumes are arranged in RAID
configurations, depending on the number of disks and their size.
If you are using the 12-disk appliance:
„ RAID 0. Creates three REO Devices. Each REO Device (physical unit
[PU]) is comprised of four disks. Each device provides either 1000 GB
(using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity.
„ RAID 5, without hot spare. Creates two REO Devices. Each REO
Device (PU) is comprised of six disks. Each device provides either 1250
GB (using 250 GB disks) or 2000 GB (using 400 GB disks) of capacity.
„ RAID 5, with hot spare. Creates two REO Devices and one hot-spare
disk. One REO Device (PU) is comprised of six disks and the other is
comprised of five disks. The five-disk device provides either 1000 GB
(using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity, and
the six-disk device provides either 1250 GB (using 250 GB disks) or
2000 GB (using 400 GB disks) of capacity.
If you are using the 24-disk appliance:
„ RAID 0. Creates six REO Devices (three physical units for each host).
Each REO Device (PU) is comprised of four disks. Each device provides
either 1000 GB (using 250 GB disks) or 1600 GB (using 400 GB disks)
of capacity.
„ RAID 5, without hot spare. Creates four REO Devices (two physical
units for each host). Each REO Device (PU) is comprised of six disks.
Each device provides either 1250 GB (using 250 GB disks) or 2000 GB

Associating Targets (Devices)
and Initiators
9
CHAPTER
The main steps involved in associating targets (REO Devices) and
initiators with each other include:
Step 1 Understanding how the targets and initiators must be identified so that
they can successfully communicate with each other.
Step 2 Making sure that IP addresses and names match on both the targets and
the initiators.
Step 3 Making another backup copy of the REO SoftKey so that your
configuration information is preserved.
Understanding How Initiators and Targets (Devices) are
Connected
To configure the REO Appliance as a backup-and-recovery-acceleration
appliance, you must provide target and initiator information. Each
volume on the REO Appliance is a target (REO Device); the servers are
initiators.
If you are using iSCSI initiators, an iSCSI name is required both at the
targets and at the initiators. An iSCSI target name is required because
it uniquely identifies a target as a storage resource for the initiators. An
iSCSI initiator name is required because it helps identify an initiator for
the purpose of target resource allocation (that is, which initiator has
access to which target resource).
If you are using FC initiators, you must provide a WWNN and WWPN for
the same purpose of providing a unique identifier.
Reviewing iSCSI Naming Conventions
iSCSI names must be unique within the domain of the end user.
However, because user domains can potentially merge with other user
domains, the iSCSI naming mechanism is structured to ensure
worldwide uniqueness. To ensure both domain and worldwide name
uniqueness, iSCSI provides for the use of different types of naming
mechanisms, based on the naming authority. Each iSCSI name is
prefixed with a short designator string that indicates the type of naming
Associating Targets (Devices) and Initiators W 87
Download from Www.Somanuals.com. All Manuals Search And Download.
Overland Storage REO 9000 with ProtectionPAC Software
authority. The iqn prefix is used for iSCSI-qualified names and the eui
prefix is used for Institute of Electrical and Electronics Engineers (IEEE)
iSCSI names.
To ensure the free movement of network HBAs between hosts without
carrying over the SCSI state information, iSCSI initiator names are
associated with iSCSI nodes instead of with network adapter cards. A
target name should not be tied to hardware interfaces, which can be
changed. A target name should identify the logical target and must be the
same for the target, regardless of the physical portion being addressed.
iSCSI-Qualified Names
iSCSI-qualified names are constructed in four parts, each separated by a
decimal. The first part of the name is the iqn prefix. The second part of
the name is a date code in yyyy-mm format. The third part is a reversed
domain name, and the fourth part is any string (within the character set
and length boundaries) that uniquely identifies the initiator or target.
For example, the iSCSI-qualified name iqn.2002-
07.com.mycompany.storage:drive1 can be broken down into four
parts as shown.
Type Date
iqn
Organization Naming Authority Subgroup Naming Authority
2002-07 com.mycompany
storage:drive1
Note: To enhance ease-of-use, the REO Appliance uses more simplified
iSCSI target names.
IEEE iSCSI Names
IEEE iSCSI names are used when a manufacturer is already basing
unique identifiers on worldwide names, as defined in the SCSI SPC-2
specification (ANSI [American National Standards for Information
Systems], 2001. NCITS.351:2001. SCSI Primary Commands - 2
[SPC-2].). IEEE iSCSI names are constructed in two parts, separated by
a decimal. The first part of the name is the eui prefix. The second part of
the name is an EUI-64 address in ASCII hexadecimal (16 digits). For
example, the IEEE iSCSI name eui.02004567A425678D can be broken
down into two parts as shown.
Type EUI-64 Worldwide Name

Reviewing How Targets (REO Devices) and
Initiators are Associated
After you have named the targets and initiators (described later in this
chapter), you must assign them to each other in pairs. This must be
performed both on the REO Appliance by using the REO Appliance
software console and on the application or backup server by using the
iSCSI initiator management tools. The following illustrations
demonstrate how this should be accomplished in an iSCSI configuration
using the Microsoft iSCSI initiator.
1 Match the Data Port IP address on the REO Appliance to the
target address on the backup server.
For example, if Data Port 1 on the REO Appliance is assigned an IP
address of 10.10.50.42, the IP address on the REO Appliance Network
Configuration page must match the target address on the iSCSI
configuration tool screens (you must launch the iSCSI configuration tool
to obtain this information) for the backup server you are configuring.
(To access the Add Target Portal dialog box,
click Add on the Target Portals tab in the
iSCSI Initiator Properties dialog box.)
(To access this dialog box, double-click the
Microsoft iSCSI Initiator icon on your desktop.)
Note: The preceding example illustrates using the Microsoft iSCSI
Configuration Tool.

2 Verify that the iSCSI Target Name on the REO Appliance
matches the target name on the backup server.
For example, if one of the volumes on the REO Appliance is named
idevice.name0, this is the iSCSI Target Name. The target name on the
REO Appliance Device Configuration page must match the target name
on the iSCSI configuration tool screens for the backup server you are
configuring.
Important: The target names must be unique within a network. If you
are using multiple appliances, you must change the default target
90 X Associating Targets (Devices) and Initiators

Setup Guide
3 Match the iSCSI initiator name on the REO Appliance to the
initiator name on the backup server.
For example, if one of the volumes on the REO Appliance is named
idevice.name0, this is the iSCSI Target Name. You must assign at least
one initiator to this target (if you do not, you will not be able to access the
disk). The iSCSI initiator name on the initiator portion of the REO
Appliance Device Configuration page must match the initiator name on
the iSCSI configuration tool screen for the backup server you are
configuring.
The Initiator IP Address field is optional. If used, both the iSCSI initiator
name and the IP address will be checked by the REO Appliance and must
match for access to be granted.
Configuring Targets (REO Devices and
External Devices) and Initiators
Each disk or LUN on the REO Appliance is an iSCSI or FC target and
has a passive role in fulfilling requests initiated by the application or
backup server.
The backup server is an initiator and plays the active role in issuing
commands. An initiator is configured in conjunction with targets on the
REO Appliance as an access control mechanism. You must configure an
initiator by using the initiator software and by using the REO Appliance
console. You can assign up to eight initiators (iSCSI, FC, or a
combination of both) to each REO disk device (a virtual tape device
currently supports only one initiator) or External Device.

Expanding Storage Capacity
(Scalability)
11
CHAPTER
This chapter explains how to add one or more additional REO Appliance
appliances to expand the storage capacity in an iSCSI or FC
environment. If you are using the 12-disk version of the REO 9000 and
you subsequently purchased the additional 12-disk upgrade kit, it also
describes how to add the additional disks to the appliance.
Important: If you purchased multiple units, set up (attach and
configure) one unit at a time. The target names must be unique within
a network; that is, if you are using multiple appliances, you must
change the default target names.
Setting Up Additional REO Appliances in
an iSCSI Configuration
1 Install, configure, and manage each REO Appliance that you purchased
using the same instructions provided for the REO Appliance that it
complements.
Using this method, you will have multiple, independent management
consoles.
2 Enable power to the first appliance and complete the configuration
process before enabling power to the next appliance, and so on.

Sharing Access to a REO 9000
Between Multiple Systems
A
APPENDIX
The ShareDevice feature lets you share a single disk (physical or virtual)
with more than one initiator. You can use this feature with any
combination of iSCSI or FC initiator connections. However, only one
initiator can access a single disk (physical or virtual) at a time.
Note: The ShareDevice feature is currently only available on Windows-
based operating systems and is not supported for tape emulation. It
also requires that the size of the device being shared is 400 GB or
smaller.
For Windows-based initiators, the product includes a set of scripts that
helps you automate the process of sharing the disks.
„ Ovlndstart.exe. You can insert this file into the pre-processing script
of the backup application to suspend operation of the backup job until
the REO Appliance is ready (not in use by another server). If your pre-
processing utilizes a script or batch file, make ovlndstart.exe the first
executable line in the file.
„ Ovlndstop.exe. You can insert this file into the post-processing script
of the backup application to flush all data from cache and then
relinquish control of the REO Appliance. If your post-processing
utilizes a script or batch file, make ovlndstop.exe the first executable
line in the file.
Important: If you do not use the scripts, you might experience errors (for
example, “Disk not ready” or “Backup device not ready”) when an
initiator attempts to access a disk that is currently being controlled by
another initiator.

Determining Whether a Disk Drive is Faulty
or There is a Problem with the REO Appliance
When there is a problem with a disk drive, its Status on the Physical
Volume Management page is reported on as NOT PRESENT, and the
disk moves to the FREE DRIVE POOL section (if you are using RAID 0,
all associated disks in the applicable volume also move to the FREE
DRIVE POOL section). The first step you can take is to force an addition
of the disk (JBOD only), re-creation of the volume that contains the disk
drive in question (RAID 0), rebuild of the volume that contains the disk
drive in question (RAID 5 without hot spares), or re-creation of a hot
spare (RAID 5 with hot spares). The next step is to replace the applicable
disk with a spare disk.
Forcing an Add (JBOD)
1 Make sure that none of the initiators (servers) have active connections
with the REO Appliance.
For example, in the iSCSI Initiator Properties dialog box for the

Glossary and Acronym List
Application server. A networked computer on which production
programs are running. The programs on an application server
typically handle application interaction between an end-user’s
browser-based programs and a company’s back-end database or
business applications. (While the application server runs the
programs and processes requests, the actual programs and data are
usually stored on a file server.)
Backup server. A networked computer that actually stores copies of
files from other computers or servers or that runs backup software
that automates the backup process of moving copies of files to separate
storage medium, such as tape.
D2D. Disk-to-disk
D2D2T. Disk-to-disk-to-tape
DHCP. Dynamic Host Configuration Protocol
File server. A networked computer on which programs and data files
are stored. (While the application server runs the programs and
processes requests, the actual programs and data are usually stored on
the file server.)
GbE. Gigabit Ethernet
HBA. Host bus adapter
Internet SCSI (iSCSI). A standard protocol for universal access to
shared storage devices over standard, Ethernet-based transmission
control protocol/Internet protocol (TCP/IP) networks. The connection-
oriented protocol transports SCSI commands, data, and status across
an IP network.
The iSCSI protocol enables block-level storage applications over TCP/
IP networks. It builds on two widely-used technologies—SCSI
commands for storage and IP protocols for networking.
„ iSCSI uses the SCSI command set, the core storage commands used
throughout all storage configurations.
„ iSCSI uses IP and Ethernet, the basis for most corporate,
metropolitan, and wide-area networks.

Overland Storage REO 9000 with ProtectionPAC Software
iSCSI uses standard Ethernet switches and routers to move the data
from server to storage. It also allows IP and Ethernet infrastructure to
be used for expanding access to storage area network (SAN) storage
and extending SAN connectivity across any distance.
Initiator. The client is an initiator that plays the active role in issuing
commands. In iSCSI terms, an initiator is a logical system component
(usually present in the form of a device driver) that sends SCSI I/O
commands to a target over an I/O bus or network. In this application,
the initiator accompanies the initiator software or IP storage HBA on
your application or backup server.
iSCSI target. The server is a target that plays the passive role in
fulfilling client requests. An iSCSI target is a logical system
component within an iSCSI appliance that receives SCSI I/O
commands from an initiator and executes them. A target includes one
or more logical units (LUs); each LU is a SCSI device, such as a disk
or tape drive. In this application, the target is the array of disks on the
REO Appliance.
FC. Fibre Channel
FC-AL. Fibre Channel Arbitrated Loop
FC-SW. Fibre Channel Switched
JBOD. Just a bunch of disks
LAN. Local-area network
LTO-2. Linear tape-open
LU. Logical unit
LUN. Logical unit number
LVM. Logical volume management
Mail server. A networked computer that stores and processes incoming
and outgoing e-mail.
Media server. A VERITAS Backup Exec server that runs the Backup
Exec engine. (Outside the VERITAS backup environment, a media
server usually refers to a server that handles the transmission of audio
and video information, such as a streaming-media server.)
Medium Changer. A secondary device that automates the movement of
media to and from a primary device.
NIC. Network interface card
Print server. A networked computer that stores and processes print
requests to a printer from an end-user’s computer and returns status
information to the end-user.
RAID. Redundant array of independent disks
