Before you start
HP StorageWorks DAT models
This guide describes how to install and operate the following HP StorageWorks DAT internal
tape drive models:
•HPStorageWorksDAT72
•HPStorageWorksDAT40
Which operating systems are supported?
HP StorageWorks DAT drives can be connected to servers running under Windows®,
NetWare, UNIX, Tru64 and Linux. Refer to the “HP StorageWorks Tape Software
Compatibility” topic on our World Wide Web site (www.hp.com/go/connect) for more
information about the operating system versions that are supported.
How do I connect the drive to my server?
You will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in
SCSI controller on your server. Your tape drive is attached to the SCSI bus of the host server
via a spare connection on the internal SCSI ribbon cable. The cable should be compatible
with low voltage differential SCSI (LVDS) and it should have a spare 68-pin, high density
(HD), wide SCSI connector. See “Checking the SCSI connection” on page 9. The cable must
be terminated, see “Step 6: Attach power and SCSI cables” on page 21.
Why is the SCSI bus type important?
The SCSI bus type determines the speed at which data can be transferred between devices on
the bus and the maximum length of cable that can be used. The drives support a burst transfer
rate of 40 MB/sec. To benefit from this level of performance, it is important to ensure that the
drives are connected to a SCSI bus of a similar or higher specification. This means that you
need:
•An Ultra Wide, Ultra2 Wide, Ultra3 (160) or Ultra4 (320) SCSI bus. Ultra Wide SCSI
supports the maximum bus speed of 40 MB per second, Ultra2, Ultra3 and Ultra4 SCSI
exceeds this.
•LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be
transferred at the drive's maximum rate.
If you attach the drive to a lower specification SCSI bus, it may still work but data will not be
transferred as quickly.
Note The drives are not compatible with high voltage differential (HVD) SCSI devices.
The following guidelines apply:
• For optimum performance the drive should be the only device on the SCSI bus.
• Always terminate the SCSI bus.
• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller.

How can I check the SCSI bus type and SCSI ID?
For many operating systems, you can install HP Library & Tape Tools from www.hp.com/
support/tapetools and run the “Install Check” to check your server’s current SCSI
configuration (see page 35). This will provide information about the SCSI bus and the SCSI
IDs in use. See also the SCSI topic in the electronic User’s Guide on the
HP StorageWorks Tape CD-ROM for other ways of checking the SCSI bus type.
What are the mounting requirements for the tape drive?
Mounting bay
You need one industry standard, 5¼-inch, half-height bay in which to install the
HP StorageWorks DAT tape drive. Power requirements are:
Mounting hardware
For many servers, no mounting tray or rails are required. Devices simply slide into the server’s
chassis and are fixed with screws. Other servers have built-in trays or rails.
Rail kits for a number of industry-standard servers may be available. For more details refer to:
www.hp.com/go/connect.
Some servers use non-standard mounting rails and do not include spares. If this is the case
with your system, you will have to order these accessories from the server manufacturer before
you can install the tape drive.
Do I need additional items for installation?
• You may need mounting hardware. See “What are the mounting requirements for the tape
drive?” above.
• If you do not have a spare, suitably-rated SCSI connector on your server, you must install a
new HBA (also known as a SCSI card). This should be of an Ultra Wide or higher SCSI
specification. You will need to purchase and install the new HBA into an unused, 64-bit PCI
expansion slot within your server before installing your tape drive. (The kit can also be
installed in a 32-bit PCI expansion slot, but performance may be degraded.)

Backup software and drivers
Backup software
For optimum performance it is important to use a backup application that is appropriate for
your system’s configuration. In a direct attach configuration, where the tape drive is attached
to a standalone server, you can use backup software that is designed for a single server
environment. In network configurations you will need backup software that supports enterprise
environments. HP, Veritas, Legato, Yosemite and Computer Associates all provide suitable
products. Further details about these and other products that may be appropriate can be
found on our connectivity web site.
1Go to our connectivity web site: www.hp.com/go/connect and select tape backup.
2Select software compatibility.
3Select your combination of operating system and tape drive model in the table. A list of
supported backup applications is displayed. This will also tell you whether your configuration
is compatible with HP One-Button Disaster Recovery, HP OBDR. (All HP StorageWorks DAT
tape drives support HP OBDR. However, you can only use this feature if your system
configuration and backup application also support it. See “Using HP OBDR” on page 33.)
4Make sure you have a backup application that supports HP StorageWorks DAT tape drives and
download any upgrades or patches, if required.
Drivers
Windows users
Before you install the tape drive, download the HP driver from our web site: www.hp.com/
support. Refer to the accompanying README file for specific installation instructions for
Windows NT, Windows 2000, Windows XP and Windows Server 2003 drivers. This will tell
you whether you need to install the driver before or after installing the tape drive.
If you do not have internet access, you can also download drivers from the
HP StorageWorks Tape CD-ROM, but these may not be the latest versions available.
UNIX users
The recommended backup applications use the operating system’s standard, built-in device
drivers. To upgrade drivers we recommend that you patch to the latest version of the operating
system or configure device files, as described in the UNIX Configuration Guide on the CD-
ROM.
IA64 users
If you are installing on an IA64 system, such as an HP Integrity server, check www.hp.com/
go/connect for the latest information on the availability of backup application upgrades
and drivers.
