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.)
Voltage Typical Current Maximum Current
5 V 3.5 A 4.0 A
12 V 0.3 A 1.7 A

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.

Checking the SCSI connection
Use the following questions to help you check your SCSI connection. As long as you have a
spare drive bay in your server you should have a spare connection on the internal SCSI bus.
You need to ensure it is the correct SCSI bus type. If you answer ‘Yes’ to all these questions,
you are ready to install your tape drive. If you answer ‘No’, you will probably need to
purchase and install additional items. For compatibility and product details, go to
www.hp.com/go/connect.
table 1: supported SCSI bus types
SCSI Bus Type Supported
Ultra wide LVD Yes. This is a recommended configuration as long as the drive is
the only device on the SCSI bus.
Ultra 2 LVD, Ultra 3 (160) LVD,
Ultra 4 (320) LVD
Yes. These are recommended configurations, particularly if there
are several devices on the SCSI bus.
Ultra wide, single-ended Yes. But this is not a recommended configuration as it will restrict
performance.
Ultra narrow, single-ended Yes. But this is not recommended as it will severely restrict
performance and you will need a suitable cable or adapter.
High Voltage Differential No. The drive will not work and you may damage the drive or
controller
1Have you checked the SCSI
bus type and SCSI IDs in use?
4You are ready to install the
drive.
3Will the drive be the only
device on the bus? This is the
recommended configuration.
Do not connect to a RAID
controller or the same SCSI
bus as your disk drive.
2Is the SCSI bus type correct
for the SCSI specification of
the drive?
See table below. If the SCSI bus differs from
the recommended specification for the drive,
performance of either the drive or the bus may
be impaired. Consider replacing your card
with one of the recommended HBAs.
Users of most operating systems can use HP
Library & Tape Tools to do this. The SCSI
topic in the online User’s Guide provides
further advice on identifying SCSI IDs.
If you have an Ultra HBA, performance may
be impaired. Consider installing (if you have
a spare PCI slot) or replacing your card with
an Ultra 2, Ultra 3 (160) or Ultra 4 (320)
HBA.

Step 1: Check the drive’s SCSI ID
Your HP StorageWorks DAT drive is shipped with a default SCSI ID of 3. 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 the server
(such as the back plate) before you remove the tape drive from its bag.
1Determine whether you need to change the SCSI ID from the default of 3.
For many operating systems you can install HP Library & Tape Tools from the
HP StorageWorks Tape CD-ROM 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.
The UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM also contains
instructions on how to determine the SCSI IDs of existing devices on UNIX servers.
2Change the tape drive’s SCSI ID, if necessary.
The SCSI ID is set using jumpers on a set of pins at the rear of the drive, as shown in figure 3.
Use tweezers or small pliers to move the jumpers to the pattern corresponding to the ID you
want. Do not remove the TP jumper. It should always be set.
Spare jumpers will be attached to the drive.

system.
1Check the UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM for specific
advice for your operating system.
The following table summarizes the typical switch settings for different types of server.
2If your UNIX configuration requires it, change the configuration switches located on the
underside of the tape drive from the default settings shown in figure 4.

Step 3: Prepare the mounting bay
Warning To avoid personal injury or damage to the server or tape drive, ensure that the server is
disconnected from the mains power supply while you install the drive.
Caution Static electricity can damage electronic components. Always wear an antistatic wriststrap if
one is available. If not, after you have disconnected power from the server and removed the
cover, touch a bare metal part of the chassis. Similarly, touch a bare metal part of the drive
before installing it.
1Assemble the necessary tools and materials:
• Phillips screwdriver
Flat-bladed screwdriver (if your server uses slotted screws)
• Torx screwdriver (if your server uses torx screws)
• Your server manuals (for reference during installation)
2Perform a normal system shutdown and turn off the server and any connected peripherals.
3Remove the cover and front panel from the server, as detailed in your server’s documentation.
As you work inside the server, you may have to disconnect the SCSI cable or power cable
from other devices to maneuver the new drive into place. If you have to do this, make a note
of their position and connections so you can put them back correctly later.
4Remove the filler panel from a spare 5¼-inch bay of your server, as described in your server’s
documentation. Keep any screws for use in “Step 7: Secure the drive” on page 23.
