1 Introduction
This poster describes how to install your HP StorageWorks Ultrium half-height tape drive.
• Connect to an Ultra320 SCSI HBA for Ultrium 920 or Ultra160 SCSI HBA (or higher)
for Ultrium 232/448.
• Use the supplied SCSI cable
• Use the correct driver
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.
Always use the power cable supplied with the tape drive. See also Safety booklet on
the CD-ROM.
4Connecting the tape drive
CAUTION: Turn off and remove the power cords from the server and all attached
accessories.
1SCSI cable 2Power cable
SCSI cable and termination
Use the 68-pin, wide, VHDCI-to-HD SCSI cable (1) supplied with the tape drive. The tape
drive provides active termination; it does not require a terminator, if it is the only or the
last device on the SCSI bus. If not, use an LVD or multimode terminator. 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.
Power cord
Use the supplied, HP approved power cord (2). This cord is appropriate for your specific
geographic region.
2Preparing the host
IMPORTANT: Refer to www.hp.com/go/connect for detailed compatibility
information about servers, operating systems, software applications and SCSI HBAs.
SCSI HBA
We recommend an Ultra320 host bus adapter for Ultrium 920. We recommend an
Ultra160 or Ultra320 host bus adapter for Ultrium 232/448. 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.
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, we recommend that you use the installer on the CD-ROM. Subsequent
updates are available from Windows Update or the HP web site. For other operating
systems, patch to the latest version of the operating system, following the instructions in the
patch documentation. See also the “UNIX Configuration Guide” on the CD-ROM.
Backup software
Always upgrade your software application to ensure it works correctly with the tape drive.
The in-box software provides full support for all the features of your tape drive.
NOTE : The HP driver is suitable for use in most applications, but refer also
to the documentation of your software application to ensure you are using the
recommended driver.
Free diagnostic tool
HP StorageWorks Library & Tape Tools (L&TT) is the recommended diagnostic and
support tool for your HP tape drive. It is available free on your HP StorageWorks
CD-ROM or at www.hp.com/support/tapetools.
Use it to verify installation, upgrade firmware and to aid in troubleshooting.
5Power on the tape drive and verify connection
1Power button
• Plug in the host server or workstation and all attached devices.
• Power on the tape drive using the power button located at the back of the tape drive.
• Check the Ready LED on the front panel to make sure the tape drive is ready for use.
• Turn on any other devices you turned off earlier. Turn on the server.
• Verify the connection using HP Library & Tape Tools.
3Checking the SCSI ID
Your HP StorageWorks Ultrium drive is shipped with a default SCSI ID of 3, but it can
beassigned 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.

6Checking the performance of your product
The Ultrium 920 tape drive can write compressed data at up to 432 GB/hour, assuming
2:1 compression. The Ultrium 448 tape drive can write compressed data at up to
172 GB/hour, assuming 2:1 compression. The Ultrium 232 tape drive can write
compressed data at up to 116.2 GB/hr, assuming 2:1 compression.
If performance is not meeting expectations and you are not meeting your backup
window, check for bottlenecks in your system architecture.
NOTE: See www.hp.com/go/connect for recommended backup applications and
SCSI HBAs and www.hp.com/support/pat for software configuration and
performance advice.
What causes bottlenecks?
1. If you back up over a network, anything less than Gigabit Ethernet may limit
performance. (100 Base-T is acceptable for Ultrium 232.)
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.
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.
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 Ultrium 920. Use an Ultra160 or
higher for Ultrium 232/448.
5. For optimum performance use HP Ultrium 800 GB and Ultrium 800 GB WORM with
Ultrium 920, HP Ultrium 400 GB cartridges with Ultrium 448 and HP Ultrium 200 GB
cartridges with Ultrium 232.

7Choosing and looking after media
Your high-performance tape drive works best with high-performance HP Ultrium media.
Always use the recommended cartridges (see table).
table1: Ultrium data cartridge compatibility
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 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).
For detailed information on media care and best practice and to order online,
refer to www.hp.com/go/storagemedia/ultrium.
