Before you start
The HP StorageWorks VS160 tape drive is a high-capacity, high-performance streaming tape
drive. Before starting to install your tape drive, you should consider the following.
Which operating systems are supported?
HP StorageWorks VS160 drives can be connected to servers running under Windows®.
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 use the tape drive with my system?
Check the usage models on page 7. This shows how the HP StorageWorks VS160 tape drive
can be used in different system configurations; direct attach and network attach.
How do I connect the drive to my server?
Your tape drive is supplied with a 68-pin, wide, VHDCI-to-HD SCSI cable to attach to the host
server. You will need a properly installed and configured SCSI host bus adapter (HBA) or a
built-in SCSI controller on your server with a spare LVDS SCSI port with a 68-pin, very high
density (VHDCI), wide SCSI connector.
For optimum performance your tape drive should only be connected to an Ultra 160 or Ultra
320 host bus adapter or SCSI controller and it should be the only device on the SCSI bus. Do
not connect more than two tape drives per SCSI controller. Do not attach the drive to the same
SCSI bus as your disk drive or RAID controller, unless it is a ProLiant server with a Smart Array
6i RAID controller.
See also Table 1, “supported SCSI bus types,” on page 11.
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. HP StorageWorks VS160 tape
drives are high performance Ultra 160 SCSI devices with a maximum burst transfer speed of
160 MB/second. 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 160 or Ultra 320 SCSI bus. Ultra 160 SCSI supports the maximum bus speed of
160 MB per second; Ultra 320 SCSI exceeds this.
•LVD-rated SCSI cabling and terminators. The LVD interface and cable enables the data to
be transferred at the drive's maximum rate and provides a maximum cable length of 12
meters.
If you attach the drive to a lower specification SCSI bus, it may still work, but data will not be
transferred as quickly. For example, on a single-ended (SE) Ultra 2 SCSI bus the maximum
burst transfer speed of the drive is 40 MB/second and the maximum cable length is restricted
to 3 meters. See also Table 1, “supported SCSI bus types,” on page 11.
Note The drives are not compatible with high voltage differential (HVD) SCSI devices.

How can I check the SCSI bus type?
We strongly recommend that you use HP Library & Tape Tools to check your server’s current
SCSI configuration. This will provide information about the SCSI bus and the SCSI IDs in use.
HP Library & Tape Tools is the recommended diagnostic and support tool for your HP tape
storage product. It is available as a free download from the HP web site and is supported on
nearly all major operating systems.
See www.hp.com/support/tapetools for compatibility information, updates and the
latest version of the tool.
Do I need additional items for installation?
• If you do not have a VHDCI, wide SCSI connector on your server, you will need to purchase
and install a VHDCI-to-HD adapter or use an HD-to-HD cable instead of the supplied cable.
• If the tape drive is not the only or last device on the SCSI bus, you must terminate the bus
with a multimode terminator. If the tape drive is the only or last device on the bus, then the
tape drive enclosure provides active termination and you do not need to purchase a
separate terminator.
• If you do not have a spare, suitably rated SCSI connector on your server, a new HBA (also
known as a SCSI card) will be required. The SCSI bus rating should match or be higher than
the SCSI rating of your tape drive. See Table 1, “supported SCSI bus types,” on page 11
for recommended HBAs. For specific details relevant to your server model please refer to
www.hp.com/go/connect. 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/dlt.

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 environment, 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.
4Make sure you have a backup application that supports HP StorageWorks VS160 tape drives
and download any upgrades or patches, if required.
Drivers
Windows users
After you connect the tape drive, download the HP driver from our web site: www.hp.com/
support, see “Step 5: Verify installation” on page 19.
Refer to the accompanying README file for specific installation instructions for Windows
2000, Windows XP and Windows Server 2003 drivers.
Note: We recommend that you install drivers from the web rather than the Windows
Hardware Installation Wizard, because the HP drivers fully support the performance of your
tape drive.

Usage models
The tape drive (B) can be used in a standalone or network environment. In a network
environment, anything less than Gigabit Ethernet may limit performance. The tape drive
should always be directly attached to a VHDCI SCSI connector on the storage server (A), as
shown in Figure 1.
A RAID disk subsystem is recommended. A single disk, particularly a fast disk such as a 15K
RPM drive, will also be sufficient, but be aware of other factors that can affect performance—
such as, compressibility of data, disk fragmentation and the number of files. You can use our
free performance assessment tools, which are available standalone or integrated into HP
Library & Tape Tools, to check tape performance and test whether your disk subsystem can
supply data at the optimum transfer rate. You can also use these tools to calibrate your restore
performance and maximal tape performance with more compressible data. See also
“Optimizing performance” on page 27.
Other models
The tape drive may work with other usage models, such as network attach storage (NAS) and
storage area networks (SAN), but HP does not currently provide technical support for
installing and using standalone DLT VS160 tape drives with these architectures. Similarly,
connection to fibre channel may be possible, if you purchase and install a fibre channel/SCSI
bridge, but it is not currently a supported option.
Please check www.hp.com/go/connect for the latest supported configurations.

Step 1: Check the SCSI connection
Use the following questions to help you check your SCSI connection. Windows users can use
HP Library & Tape Tools to check the SCSI bus type, see page 26. 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 product details, go to www.hp.com/go/
connect.
table 1: supported SCSI bus types
SCSI Bus Type Transfer Speed Supported
Ultra 160 LVD Up to 160 MB/s Yes. This is a recommended configuration.
Ultra 320 LVD Up to 320 MB/s Yes. This is a recommended configuration.
Ultra 2 LVD Up to 80 MB/s Yes, but this is not recommended
Ultra single-ended,
wide
Up to 40 MB/s Yes, but this is not recommended as it will restrict
performance. Do not connect to a narrow SCSI bus.
High Voltage
Differential
Up to 40 MB/s 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
VHDCI SCSI connector?
3Will the tape 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 device?
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.)
Performance may be impaired. Consider
installing (if you have a spare PCI slot) or
replacing your card with an Ultra 320 HBA.
Make sure the last device on the bus is
terminated.

Figure 4: checking the SCSI ID
dltvs160_master.fm Page 12 Monday, November 22, 2004 10:33 AM

Step 2: Check the drive’s SCSI ID
1Determine whether you need to change the SCSI ID from the default of 6.
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.
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 4) until the required value is displayed. Do not use a pencil because
small bits of graphite could contaminate the drive.
Note The server and the tape drive SCSI IDs are only checked at power-on. To change the SCSI ID
after installation, power down both the server and the tape drive, change the tape drive’s
SCSI ID, power up the tape drive, and then power up the server.
Your HP StorageWorks VS160 drive is shipped with a default SCSI ID of 6, but it 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.

Figure 5: connecting the SCSI cable
dltvs160_master.fm Page 14 Monday, November 22, 2004 10:33 AM

15
Step 3: Attach SCSI cable
A wide VHDCI-to-HD SCSI cable is provided to connect your HP StorageWorks VS160 tape
drive to a VHDCI SCSI port on an LVD SCSI bus. If your server has an HD SCSI port, you must
either purchase and install a VHDCI-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 server 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 “Step 1: Check the SCSI
connection” on page 11. For optimum performance, we recommend that your
HP StorageWorks VS160 tape drive is installed on a dedicated SCSI bus. If it is not, do not
connect it to the same bus as your disk drive. Do not connect the tape drive to the same bus
as a RAID controller, unless you are connecting to a ProLiant server with a Smart Array 6i RAID
controller.
Note: The recommended connections support a maximum bus length of 12 meters. However,
if you daisy chain the tape drive with an Ultra device, cable length is restricted to 3 meters.
Use a 1.8 meter cable to attach the initial unit and a 0.9 meter cable to daisy chain the
additional tape drive. Do not connect more than two tape drives per SCSI controller.
2Perform a normal system shutdown and turn off the server and any connected peripherals.
3Attach the VHDCI 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 tape 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: Attach power cable
An external HP StorageWorks VS160 tape 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 tape drive to the
power supply, proceed as follows:
1Make sure that the tape drive is switched OFF. The power switch is on the rear panel.
2Plug the power cable securely into the socket on the rear panel of the tape drive. (See Figure 6.)
3Plug the other end of the power cable into the power outlet.

Step 5: Verify installation
Check operation
1Switch on the tape drive and server. The tape drive will run its hardware self-test, which takes
up to 25 seconds (with no cartridge loaded). If self-test passes, the Ready LED remains on and
the other LEDs are off. See “Understanding the LEDs” on page 34 for more information about
the LEDs.
2Install drivers and backup software.
On Windows systems, the Windows Hardware Installation wizard is displayed
automatically. We recommend that you close the wizard and install the drivers from the HP
web site at www.hp.com. For all operating systems ensure that you have downloaded any
upgrades necessary for your backup application (see page 5).
3Verify that the tape drive installation was successful.
For most operating systems use HP Library & Tape Tools as described on page 26.
If you encounter a problem during this verification procedure, turn to “Troubleshooting” on
page 29 for help in diagnosing and fixing the problem.
4You are now ready to carry out a backup and restore test to check that the drive can write data
to tape. Use a blank DLTtape VS1 cartridge. See “Use the correct media” on page 23 for more
information about recommended cartridges. Refer to your backup application documentation
for specific instructions.
To load a cartridge
1Insert the DLTtape VS1 cartridge into the slot in front of the drive with the markings uppermost
and facing the drive door. Apply gentle pressure until the drive takes the cartridge and loads
it. See Figure 7a.
2The Ready LED flashes green while the drive performs its load sequence. When the cartridge
is ready for use, the Ready LED shows steady green. (If the Media LED is also on, you have
used a DLTtape 1V (VS80) cartridge. See “Use the correct media” on page 23.)
To unload a cartridge
Caution Never try to remove a cartridge before it is fully ejected or power off the tape drive while a
cartridge is still loaded. Failure to remove a data cartridge may result in cartridge or tape
drive damage.
1Press the Eject button on the front panel. (See Figure 7b.)
2The drive will complete its current task, rewind the tape to the beginning, and eject the
cartridge. The Ready LED will flash to indicate that the unload is still in progress and will show
steady green, when the cartridge is ready for removal.
