Before you start
HP StorageWorks DAT models
This guide describes how to install and operate the following HP StorageWorks DAT external
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 supplied with a VHD-to-HD cable to attach
the drive to a spare, external VHD SCSI port on the server. It is also shipped with a multimode
terminator. The cable and terminator are appropriate for a wide, low voltage differential (LVD)
or single-ended (SE) SCSI bus.
If the SCSI cable supplied with your drive is not appropriate for your computer’s external SCSI
connector, you will need to order an adapter or new cable. See also "Checking the SCSI
connection" on page 9.
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 and provides a maximum cable length of 12 meters.
The following guidelines apply:
• For optimum performance the drive should be the only device on the SCSI bus.
• Always terminate the SCSI bus. Use the supplied terminator.
• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller.

If you attach the drive to a lower specification SCSI bus, it may still work but data will not be
transferred as quickly and you will need to use shorter cable lengths.
Note The drives are not compatible with high voltage differential (HVD) SCSI devices.
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 29). 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.
Do I need additional items for installation?
• If you have an HD rather than a VHD, wide SCSI connector on your server, you will need to
purchase and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the supplied
cable.
• 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.)
Refer to our World Wide Web site for recommended products, configurations and ordering
information: www.hp.com/go/connect or www.hp.com/support.

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 27.)
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.

Using the CD-ROM
HP product registration
To register your new tape drive electronically via the web, use the “Product Registration” link
on the HP StorageWorks Tape CD-ROM.
Drivers
For detailed information about drivers, refer to the appropriate README file in the DRIVERS
directories on the HP StorageWorks Tape CD-ROM. There is a separate sub-directory for each
operating system.
User documentation
Refer to the “User Documentation” topic on the HP StorageWorks Tape CD-ROM for a UNIX
Configuration guide and an online User’s Guide that provides more detailed information
about using your HP StorageWorks DAT tape drive.
Refer to your backup application’s documentation for instructions on how to back up and
restore data.
HP Library & Tape Tools
HP Library & Tape Tools software provides diagnostic and troubleshooting utilities. It allows
you to identify your product correctly, check SCSI ID information on the SCSI bus, run tests,
carry out firmware upgrades and, if necessary, generate comprehensive troubleshooting
information for support calls. Use the link on the HP StorageWorks Tape CD-ROM to access
our Support web site, www.hp.com/support/tapetools, and download the latest
version of this software. For further details see page 29.
CD-ROM guide
The CD-ROM guide provides an overview of the CD directory structure and information about
the languages in which the contents of the CD-ROM are available. It also contains a set of
URLs and links for further information.
The HP StorageWorks Tape CD-ROM contains drivers, useful utilities and information to help
you install and use your tape drive. Before installation, most users can use the HP Library &
Tape Tools software to check SCSI ID information on the SCSI bus. The UNIX Configuration
guide on the CD-ROM also contains information about checking SCSI IDs on UNIX systems.
