IMPORTANT INFORMATION ABOUT YOUR NEW TAPE DRIVE
For the most up-to-date information about supported SAS HBAs and cabling
configurations, refer to www.hp.com/go/connect and be sure to check the details of
the specific tape drive and server combination that you require.
The most cost-effective way of connecting the tape drive to an HP ProLiant server is to
use the split cable supplied with the drive. However, be aware that installation
decisions require a clear understanding of your server's current SAS configuration.
• With some servers you can connect to a spare SAS connector on the SAS controller.
This is a straightforward installation and recommended.
• With servers that do not have a spare connector, you will need to recable hard disk
drive bays. In a few instances, you may also lose the use of one of the hard disk
drive bays. Caution is advised for this installation. Do NOT use this cabling option,
if the hard disk drive bay is already occupied or will be required for future use.
The simplest way of connecting a tape drive to your HP server is to purchase and install
one of the supported HBAs, see www.hp.com/go/connect. This option may also be
used with non-HP servers as long as the third-party manufacturer supports the HP SAS
controller installed in their server and provides adequate airflow to cool the tape drive.
For information about airflow requirements and detailed, step-by-step installation
instructions, refer to the "User Guide" from the Documentation link on the HP
StorageWorks CD-ROM.

This poster describes how to install an HP StorageWorks Ultrium 1760/920/448 SAS
tape drive on a SAS server.
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.
For detailed safety information, see the Safety Booklet on the CD-ROM.

Refer to www.hp.com/go/connect
Before you install your tape drive, always refer to www.hp.com/go/connect to find out:
• Is connection to your SAS server supported?
• Can you connect to the host SAS controller or do you need to purchase an additional
HBA?
• If you connect to the host SAS controller, does it have a spare SAS port to which you can
attach the supplied cable or must you use the supplied cable to replace one of the existing
cables? If so, will you lose the use of a hard disk drive bay and which one will it be?
• If you connect to a new HBA, can you use the supplied cable or must you purchase an
additional cable.
Not sure how to use go/connect?
Select tape backup and navigate down to the Hardware Compatibility table for your
make of server. The server/tape drive matrix shows top-level compatibility, but be sure to
click on the box for your combination of server and tape drive to display a further page
with detailed connectivity information.

Decide on your installation model
You may damage your server configuration, if you follow the wrong cabling instructions.
Use the following diagram to determine which instructions on this poster are appropriate
for your server.

The supplied split cable may be used to connect to the host controller on the SAS server
or to an additional SAS HBA. It has three connectors, as shown below.
Supplied SAS Cable
• If you are connecting to a spare connector on the host HBA (Option 1) or to an
additional HBA (Option 3), you will use only two of the connectors. This will leave
unused cabling within the server, which should be coiled and secured tidily.
• If you are connecting to the host controller by replacing an existing SAS cable (Option 2),
you will use all three connectors. Depending on server model, this may affect your hard
disk drive configuration.
Option 1: Connect to a spare port on the host
HBA (some HP ProLiant servers only)
The following instructions are valid ONLY IF the host SAS controller on your HP ProLiant
server has a spare SAS connector.
TIP: The CD-ROM contains a driver install package for Windows. For ease of use
we recommend that you use the installer package to install the drivers BEFORE you
connect the tape drive.
1. Attach the mounting hardware (some servers only)
Check your server documentation to find out if mounting hardware is required. If it is,
attach the appropriate mounting hardware. Screw packs are supplied with the tape drive
and labeled according to 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.
Use screws supplied

Do not use screws

Use shims with Proliant ML350
and ML370 servers only.
NOTE: The illustration shows one method of mounting hardware; it does not apply to
all servers. Please refer also to the "User Guide" and your server documentation.
2. Install the tape drive
Install the tape drive, as described in the "User Guide" on the CD-ROM.
TIP: If cable access for the tape drive bay is awkward, it may be easier to access
power and other connections if the tape drive is installed in the top bay. You may
need to move other devices to lower bays to achieve this.
3. Connect the SAS cable supplied with the tape drive to the
spare SAS port on the host SAS controller.

Never use a cable where power is supplied through the SAS connector.
CAUTION:
Always use a spare power cable from the server's internal power supply.

5. Power up the server
Power up the server. Watch the boot screen carefully after installation. Check to see that
the new SAS tape drive is listed in the boot sequence. If there are any error or
unexpected messages go back and check the SAS cabling carefully.
6. Install drivers
Windows
The driver available from Microsoft update is acceptable, but the HP driver (available on
the CD-ROM or the web) provides better support for all the features of your new tape
drive. The CD-ROM contains a driver install package. You may install the driver before or
after connecting the tape drive.
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.
7. Upgrade backup software
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.
Hardware encryption and your Ultrium 1760
tape drive
Your HP Ultrium 1760 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 Ultrium 1.6 TB
media (C7974A and C7974W); media encrypted on an HP Ultrium 1760 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. The software
supplied with the tape drive provides this support. See
an up-to-date list of backup software.
C
• 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 HP
Support will be able to access the encrypted data.
