Introduction

This poster describes how to install your Tandberg LTO half-height tape drive.
• Use the fixing screws supplied with the tape drive
• Connect to an Ultra320 SCSI HBA for LTO-4/LTO-3 or Ultra160 SCSI HBA
(or higher) for LTO-2 using a supported SCSI cable
• Use the correct driver
Tandberg LTO-2, LTO-3 and LTO-4
HH SCSI Internal Tape Drives
Check the drive’s SCSI ID
Your Tandberg LTO HH tape drive is shipped with a default SCSI ID of 2. Each
device on the SCSI bus must have an unique SCSI ID number. The drive can be
assigned any unused ID between 0 and 15. Do not use SCSI ID 7, which is
reserved for the SCSI controller. SCSI ID 0 is typically assigned to the boot disk
and should also not be used unless the tape drive is on a dedicated SCSI bus.
CAUTION: Static electricity can damage electronic components. Always wear
an antistatic wriststrap if possible. If not, to equalize the electromagnetic
charges, touch a bare metal part of theserver (such as the back plate) before
you remove the tape drive from its bag.
WARNING: To avoid personal injury or damage to the server or tape drive,
disconnect your server from the mains power supply before installing the tape
drive.
To avoid damage to server or tape drive observe all recommended anti-static
and power-grounding precautions, as specified in your server and tape drive
manuals.

Preparing the host
IMPORTANT: Refer to www.tandbergdata.com for detailed compatibility
information about operating systems and software applications.
SCSI HBA
We recommend an Ultra320 host bus adapter for LTO-4/LTO-3. We recommend an
Ultra160 or Ultra320 host bus adapter for LTO-2. If necessary, install a new HBA
before you connect the tape drive. Ensure that you are connecting to a supported
HBA running the recommended firmware version.
(Default)
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
C
For Windows systems, download the latest drivers from www.tandbergdata.com.
For other operating systems, patch to the latest version of the operating system,
following the instructions in the patch documentation.

CAUTION: Turn off and remove the power cords from the server and all
attached accessories.

Backup software
MY
CY
Always upgrade your software application to ensure it works correctly with the
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.

Attach mounting hardware – all servers
Screw packs are labeled for each server type; always use the specific screws for
your server. Follow the instructions in the screw pack. You may damage your
tape drive if you use screws that are too long, because the Tandberg LTO
half-height tape drive allows only 3mm of the engagement of the screw into
the drive.

2 Power cable
SCSI cable and termination
Check your server or HBA documentation to ensure that the SCSI bus and cabling
are the correct specification for your tape drive: an Ultra320 bus for Tandberg LTO-4
and LTO-3 drives, an Ultra160 or Ultra320 SCSI bus for Tandberg LTO-2 drives. We
recommend that you attach the SCSI ribbon cable supplied with the tape drive to
the SCSI host bus adapter. Daisy-chaining multiple devices is not recommended. If
you do so, do not mix drive families (only daisy-chain with other LTO tape drives)
and attach no more than two devices to the same SCSI bus. If the drive is the last
device on the SCSI chain, make sure that the SCSI cable is terminated correctly.
Power cable
Attach a spare power cable from the server's internal power supply to the power
connector (2).

Power on the tape drive and verify connection
• Plug in the host server or workstation and all attached devices.
• Turn on any other devices you turned off earlier. Turn on the server.
• Check the Ready LED on the front panel to make sure the tape drive is ready for
use.
• Verify the connection.

Checking the performance of your product
If performance is not meeting expectations and you are not meeting your backup
window, check for bottlenecks in your system architecture.
NOTE: See www.tandbergdata.com for recommended backup applications,
SCSI HBAs and for software configuration and performance advice.

Choosing and looking after media
Your high-performance tape drive works best with high-performance Tandberg LTO
media. For optimum performance always use a data cartridge that matches the
specification of your tape drive (see table).

The recommended cleaning cartridge is the Tandberg LTO universal cleaning
cartridge. This cartridge is designed to work with any Ultrium drive and may be
used for up to 50 cleans.

• Check media type
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 acclimitization 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).

you back up over a network, anything less than Gigabit Ethernet may limit
performance.

Understanding the LEDs

• Power cycle drive
• Try another tape
Cartridge will not

• 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. The
software supplied with the tape drive provides this support. See
www.tandbergdata.com for an up-to-date list of backup software.
• 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
Tandberg Data Support will be able to access the encrypted data.

• Check power
Check SCSI cables
• Check SCSI ID
• Can OS see it?
(eg in Windows Device

• Press the eject button.
Wait for up to 10 minutes.
• If ejected check media

Other sources of information
If you need technical support or have any problem with your LTO-2 HH, LTO-3 HH
or LTO-4 HH tape storage solution, phone, fax and addresses can be found under
www.tandbergdata.com SUPPORT.
Your Tandberg 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 Tandberg
LTO-4 1.6 TB media; media encrypted on a Tandberg LTO-4 drive can only be
read on a compatible Ultrium tape drive that supports hardware encryption.
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.

troubleshooting guide at
www.tandbergdata.com
• Contact Support
There is a more detailed "User Guide" on www.tandbergdata.com.
Hardware encryption and your Tandberg LTO-4
tape drive
Hardware encryption can be used with or without compression and without speed
or capacity penalties.
• Check media for
damage
• Try another tape
5. For optimum performance use LTO-4 1.6 TB R/W and WORM for Tandberg
LTO-4 tape drives, LTO-3 800 GB and 800 GB WORM with Tandberg LTO-3 tape
drives, LTO-2 400 GB cartridges with Tandberg LTO-2 tape drvies.

Problem not
resolved
• Clean drive
3. Use the latest version of your backup application. Native backup applications,
such as Windows backup, may limit performance.
10
Further
Action
• Check media age
Server or backup
application cannot
see drive
2. A single disk may limit backup performance. Have disks in parallel (e.g. RAID5)
if possible or, if your backup application supports interleaving of data, back up
streams from multiple sources.
4. Connect the tape drive to a dedicated SCSI bus.
SCSI card: Use a PCI-express or a 64-bit PCI expansion slot. 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.
