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.
dds-external-frame6.fm Page 3 Tuesday, January 6, 2004 11:50 AM

4
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.

Checking the SCSI connection
Use the following questions to help you check your SCSI connection. Many users can use HP
Library & Tape Tools to check the SCSI bus type, see page 29. 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
1Is there a spare SCSI port on
your server?
4Does the HBA/controller have
a VHD SCSI connector?
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.
Purchase and install one of the recommended
HBAs into an unused 64-bit PCI expansion
slot. (The HBA can also be installed in a 32-
bit PCI expansion slot, but performance may
be degraded.)
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. Make sure the last device on the bus is
terminated.

Figure 3: checking the SCSI ID
dds-external-frame6.fm Page 10 Tuesday, January 6, 2004 11:50 AM

11
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.
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 29). 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.
Use a small screwdriver or a ball-point pen to press the indented SCSI ID selector buttons on
the rear panel (see figure 3) until the required value is displayed. Do not use a pencil because
small bits of graphite could contaminate the drive.
Note The computer and the tape drive SCSI IDs are only checked at power-on. To change the SCSI
ID after installation, power down both the computer and the tape drive, change the drive’s
SCSI ID, power up the tape drive, and then power up the computer.

dds-external-frame6.fm Page 14 Tuesday, January 6, 2004 11:50 AM

15
Step 3: Connect the SCSI cable
A wide VHD-to-HD SCSI cable is provided to connect your HP StorageWorks DAT tape drive
to a VHD SCSI port on an LVD SCSI bus. If your server has an HD SCSI port, you must either
purchase and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the supplied
cable. Refer to our web site for recommended products: www.hp.com/go/connect.
Caution To avoid damaging the computer or tape drive, ensure that both are powered off while you
attach the SCSI cable.
1Make sure you are connecting to a recommended SCSI bus type. See “Checking the SCSI
connection” on page 9. Do not connect the tape drive to the same bus as a RAID controller.
For optimum performance, we recommend that your HP StorageWorks DAT drive is installed
on a dedicated SCSI bus. If it is not, do not connect it to the same bus as your disk drive.
2Perform a normal system shutdown and turn off the server and any connected peripherals.
3Attach the VHD connection on the SCSI cable to the server’s external SCSI connector and
secure it by tightening the screws.
4Attach the HD connection on the SCSI cable to one of the SCSI connectors on the rear panel
of the tape drive and secure it by tightening the screws. (See figure 5.)
5Connect the multimode terminator to the drive’s other SCSI connector and tighten the screws to
secure it. The multimode terminator detects whether the host bus adapter is SE or LVD and
automatically provides the appropriate termination.
Why does the tape drive need a terminator?
Terminators are essential, as they provide the correct voltages on the SCSI bus and prevent
unwanted signal reflections from interfering with data transfers. The rule is:
There must be termination at both physical ends of the bus and only at the ends.
Normally the HBA forms one end of the SCSI bus and provides termination. You, therefore,
need to ensure that the other end of the bus is terminated. If the tape drive is at the end of
the SCSI bus, the terminator must be attached to the tape drive.
If you want to attach additional devices to the SCSI bus after the tape drive, you will need
to remove the SCSI terminator and attach the next device to this SCSI connector. Make sure
that you attach the terminator to the last device in the chain.

Step 4: Connect the power cable
An external HP StorageWorks DAT drive will operate using any voltage in the range 100–
240 volts (0.7 A, 50-60 Hz). No adjustment is needed. To connect your drive to the power
supply, proceed as follows:
1Make sure that the drive is switched OFF (O side down). The power switch is on the rear
panel.
2Plug the power cable securely into the socket on the rear panel of the drive. (See figure 6.)
3Plug the other end of the power cable into the power outlet.
