LTO Half-Height SCSI
External Tape Drive
Quick Start Guide
Overview
This document describes how to unpack and install an
Overland LTO Half-Height SCSI External Tape Drive to
an external host bus adapter (HBA) port using a
purchased cable.
WARNING: To reduce the risk of electric shock or damage
to equipment, always remove any power cords while
working with the unit.
AVERTISSEMENT: pour réduire le risque de choc
électrique ou endommagement de l'équipement, retirez
toujours les cordons électriques en travaillant avec l'appareil.
CAUTION: While working with the unit, observe standard
Electrostatic Discharge (ESD) precautions to prevent
damage to micro-circuitry or static-sensitive devices.
NOTE: Cables are not supplied in the External Tape Drive
product kits. These cables must be purchased separately.

Introduction
Before you install your tape drive, make sure that:
•You are connecting to an Ultra320 SCSI HBA for an
LTO-4/LTO-3 drive or an Ultra160 SCSI HBA (or
higher) for an LTO-2 drive using a supported cable.
•You are using the correct driver.
Preparing The Host
SCSI Cable and Termination
Use a 68-pin, wide, supported SCSI cable (1) to connect to
the drive. The tape drive provides active termination (it
does not require a terminator) if it is the only device on
the SCSI bus.
Daisy-chaining multiple devices is not recommended. If
you do so, do not mix drive families (only daisy-chain
with other Ultrium tape drives) and attach no more than
two devices to the same SCSI bus. The last device on the
SCSI chain must be terminated correctly.
SCSI HBA Card
If you do not already have a SCSI HBA card installed,
you must purchase a supported HBA card along with a
matching cable. You need a spare PCI slot for the card.
Your tape drive will work with lower-rated LVDS SCSI
but performance may be degraded. Single-ended SCSI
will degrade performance and limit cable length. Do not
attach to narrow or HVD SCSI.
Drivers
For Windows systems, download the latest drivers from
the HP tape drive drivers web site. For other operating
systems, patch to the latest version of the operating
system, following the instructions in the patch
documentation.
Backup software
It is recommended to upgrade your backup software
application to ensure it works correctly with the new
external tape drive. We do NOT recommend native
backup applications, such as Windows Backup, because
they do not support the full features of the tape drive and
may cause performance problems.
NOTE: Some backup applications require you to use their own
drivers. Refer to the documentation of your software
application to ensure you are using the recommended driver.

Checking the SCSI ID
Your LTO Half-Height tape drive is shipped with a
default SCSI ID of 2, but it can be assigned any unused
ID between 0 and 15. Do not use SCSI ID 7, which is
reserved for the SCSI controller, or SCSI ID 0, which is
typically assigned to the boot disk.
Connecting the Tape Drive
CAUTION: Turn off and remove the power cords from the
server.
1. Connect the SCSI cable to the server HBA card.
The cable connector may be different than the one
pictured depending on the HBA card used.
2. Connect the SCSI cable (1) and power cord (2) to the
tape drive.
3. Power up the tape drive and server.
a. Power on the tape drive using the power button
located at the front of the tape drive.
b. Check the Ready LED on the front panel to make
sure the tape drive is ready for use.
c. Plug in and turn on the host server.
Watch the boot screen carefully during the boot
process. Check to see that the new tape drive is
listed in the boot sequence.
NOTE: If there are any error or unexpected messages, go
back and check the SAS cabling carefully.
Checking Product Performance
If performance is not meeting expectations and you are
not meeting your backup window, check for bottlenecks
in your system architecture.
What causes bottlenecks? Review the numbered items
that follow which match the graphic numbering below.
1. We recommend direct connection for LTO-4 and
LTO-3 tape drives. If you back up over a network,
anything less than Gigabit Ethernet may limit
performance.
2. A single disk may limit backup performance. Have
disks in parallel (for example, RAID 5) if possible or, if
your backup application supports interleaving of data,
back up streams from multiple sources.

3. Use the latest version of your backup application.
Native backup applications, such as Windows backup,
may limit performance.
4. Connect the tape drive to a dedicated SCSI bus. Use a
PCI-express or a 64-bit PCI expansion slot for your
SCSI card. Use an Ultra320 SCSI HBA in a 64-bit/
66MHz or better expansion slot for LTO-4/LTO-3. Use
an Ultra160 or higher for LTO-2.
5. For optimum performance, use LTO-4 R/W and
WORM cartridges with LTO-4 tape drives, LTO-3 R/W
and WORM cartridges with LTO-3 tape drives, and
LTO-2 R/W cartridges with LTO-2 tape drives.
LTO-4 Hardware Encryption
Your LTO-4 tape drive provides the ability to hardware
encrypt your data, applying the strongest level of AES
industry-standard encryption and protecting the data
from unauthorized access and use. Encryption is
supported only on LTO-4 media (1.6 TB); media
encrypted on a LTO-4 drive can only be read on a
compatible Ultrium tape drive that supports hardware
encryption.
Hardware encryption can be used with or without
compression and without speed or capacity penalties.
IMPORTANT: Hardware encryption is a powerful feature, but
should be used with care. If you need to import your media
onto another machine or to recover after disaster you will be
required to enter an encryption key.
•Hardware encryption is turned off by default and is
switched on by settings in your backup application,
where you also generate and supply the encryption
key.
•Your backup application must support hardware
encryption for it to work.
•You should keep a record or backup of your encryption
keys and store them in a secure place separate from
the computer running the backup software.
•If you are unable to supply the key when requested to
do so, neither you nor Overland Storage will be able to
access the encrypted data.
Understanding LEDs
Media Choice and Care
Your high-performance tape drive works best with high-
performance LTO media. For optimum performance,
always use a data cartridge that matches the
specification of your tape drive (see Table 1).
The recommended cleaning cartridge is the LTO
universal cleaning cartridge. This cartridge is designed to
work with any Ultrium drive and may be used for up to
50 cleans.
1. Clean – amber
•On: cleaning cartridge in
use.
•Off: the drive does not
require cleaning.
•Flashing: the drive needs
cleaning.
2. Tape – amber
•Off: no fault has been
detected.
•Flashing: the cartridge
currently in the drive is faulty
(damaged / unsupported).
Discard the cartridge.
3. Drive – amber
•Off: no fault has been
detected.
•Flashing: the drive
mechanism has detected a
hardware error.
4. Ready – green
•On: the drive is ready for
use.
•Off: the drive power is off or
there was a failure during
self-test.
•Flashing: the drive is busy.

It Pays to Look After Your Media
Many tape drive and backup failures are caused by
damaged or badly handled tape media.
•Keep media in the case provided.
•Follow the temperature, humidity, and
acclimatization guidelines on the media packaging.
•Avoid dropping it or rough handling, as this is likely to
damage the cartridge.
•Inspect it regularly for damage.
•Do not exceed normal cartridge life (260 full volume
backup or restore operations).
For detailed information on media care and best practice
and to order online, refer to Overland's web site.
