IMPORTANT INFORMATION ABOUT YOUR NEW TAPE DRIVE
The recommended and simplest way of connecting a tape drive to your HP or non-HP
SAS server, is to purchase and install one of the supported HBAs, see
www.hp.com/go/connect. A cable is supplied with the tape drive to connect to an
external port on a dedicated HBA.
The supplied cable may also be used to connect to an active external port on the host
SAS controller.
An alternative option for HP ProLiant servers is to connect to an internal port on the
server's SAS controller. This option uses an HP SAS split cable, which must be
purchased separately. Be sure to purchase the correct cable for your connector type -
mini-SAS or Infiniband-style SAS.
• HP SAS split cables contain four data paths, which normally support up to four
hard disks. Both the HP SAS Infiniband and the HP Mini-SAS split cables divert
one of these data paths to the tape drive.
Use this option with care; it requires a clear understanding of your hard disk
configuration.
For the most up-to-date information about supported SAS HBAs and cabling
configurations, refer to www.hp.com/go/connect and be sure to check the details of the
specific tape drive and server combination that you require.

1 Refer to www.hp.com/go/connect
Before you install your tape drive, always refer to www.hp.com/go/connect to find out:
• Is connection to your SAS server supported?
• Which HBAs are recommended for dedicated tape connect?
If you connect to the host SAS controller (not recommended), does it have an active
external port? The supplied cable is suitable for this installation.
If you decide to connect to an internal SAS port, which HP SAS cable should you purchase
- mini-SAS or Infiniband-style?
• If you connect to an internal port on the host SAS controller, does it have a spare SAS
port to which you can attach the HP SAS split cable or must you use the HP SAS split
cable to replace one of the existing cables? If so, will you lose the use of a hard disk
drive bay and which one will it be?
Not sure how to use go/connect?
Select tape backup and navigate down to the Hardware Compatibility table for your
make of server. The server/tape drive matrix shows top-level compatibility, but be sure to
click on the box for your combination of server and tape drive to display a further page
with detailed connectivity information.
2 Decide on your installation model
This poster describes how to connect an HP StorageWorks DAT 320 or DAT 160 SAS
tape drive to an external port using the supplied SAS cable or to an internal port using
one of the HP SAS split cables.
You may damage your server configuration, if you follow the wrong cabling instructions.
Use the following diagram to determine which instructions on this poster are appropriate
for your server.
NOTE:
The supplied cable connects to an external HBA. If you wish to connect
the tape drive to an internal port on the server's host SAS controller, be sure to
purchase the appropriate split cable for your connector type (Infiniband-style or
mini-SAS).
Options 2 and 3 require a spare PCI slot because the cable and SAS connector to
the tape drive are threaded through a PCI slot on the server’s back panel. Option 1
requires a spare PCI slot if you install a dedicated HBA (recommended).
For detailed, step-by-step installation instructions, print the “User Guide” from the
Documentation link on the HP StorageWorks CD-ROM.
WARNING:
To avoid personal injury or damage to the server or tape drive,
disconnect your server from the mains power supply before installing the tape drive.
To avoid damage to server or tape drive observe all recommended anti-static and
power-grounding precautions, as specified in your server and tape drive manuals.
For detailed safety information, see the Safety Booklet on the CD-ROM.
Options 2 & 3 are shown overleaf
These offer an alternative cabling solution for some
HP ProLiant servers only

Option 1: Connect to an external SAS port
(recommended for all HP and non-HP servers)
A SAS cable for connection to an external port is provided with the DAT 320 tape drive.
This is suitable for connecting to a dedicated HBA (recommended) or to an active external
port on the host controller. See http:\\www.hp.com\go\connect for recommended HBAs.
TIP:
The CD-ROM contains a driver install package for Windows. We recommend
that you use the installer package to install the drivers
BEFORE
you connect the tape
drive.

NOTE:
The power switch on the DAT 160 is on the rear panel.
3. Power up the tape drive and server
Switch on the tape drive and power up the server. Watch the boot screen carefully after
installation. Check to see that the new SAS tape drive is listed in the boot sequence.
If there are any error or unexpected messages go back and check the SAS cabling carefully.
4 Complete the installation
• Install drivers. The HP Tape driver (available on the CD-ROM or from
http: www.hp.com/support) is recommended for use with Windows operating
systems, but always check whether your software application requires you to use its
own driver. For other operating systems patch to the latest version of the operating
system and following the instructions in the patch documentation. See also the “UNIX
Configuration Guide” on the CD-ROM.
• Upgrade your software application to ensure it works correctly with the tape drive.
When selecting the media to use with the backup application, you should select 8mm
media with DAT 320 and DAT 160 tape drives. We do NOT recommend native
backup applications, such as Windows Backup, because they do not support the full
features of the tape drive and may cause performance problems.
• HP StorageWorks Library & Tape Tools (L&TT) is the recommended diagnostic and
support tool for your HP tape drive. Use it to verify installation and confirm that your
tape drive is functioning correctly before you use it for backup. It is available free at
www.hp.com/support/tapetools.

Option 3: Replace existing cable and connect to
port on the host HBA (some HP ProLiant servers only)
The following instructions apply ONLY IF you are connecting the external tape drive to an
internal connector on the host SAS controller that is already in use.
This installation uses the HP Infiniband-style or mini-SAS split cable to replace an existing
SAS cable connected to an internal port on the host SAS controller. It requires a spare
PCI slot to accommodate the cable bracket and SAS connector to the tape drive. The
cable must be purchased separately. Refer to http://www.hp.com/go/connect to find out
which cable is appropriate.
1 Infiniband-style connector found on many older ProLiants
2 Mini-SAS connector found on some ProLiants
CAUTION: Be aware that this option will disconnect the highest-numbered disk bay
because it diverts the wiring from the highest-numbered hard disk bay to the tape
drive. Do NOT use this cabling option, if the hard disk drive bay is already
occupied or will be required for future use.
You will not be able to use the highest-numbered disk bay after installation. If you
install a hard disk in this bay, the disk will not work. This does not mean there is a
fault with either the hard disk or the server.
You may need to remove components, such as fan banks, while you work with the cable.
Cable routing varies from one server to another. Always refer to your server documentation
to identify the location and orientation of SAS connectors and for specific advice on cable
routing.
TIP:
The CD-ROM contains a driver install package for Windows. We recommend
that you use the installer package to install the drivers
BEFORE
you connect the tape
drive.
1. Locate existing SAS cable and determine whether a hard
disk drive bay will be lost
Refer to www.hp.com/go/connect to find out which cable must be removed and whether
you will lose the use of a hard disk drive bay.
Look at the front of the server to establish how the hard disk drive bays are numbered.
CAUTION:
If the hard disk drive bay is in use,
STOP
. Even if other hard disk drive
bays are empty, the installation will not work. (Do not move a hard disk to create an
empty bay because you may damage your server configuration.) You must purchase
and install a new HBA.
Locate the cable that connects the hard disk drive bay to the SAS controller (HBA) and
remove it completely (the existing cable will be replaced by the supplied cable).
1 Host SAS controller (HBA)
2. Feed the replacement SAS cable through the server rear
panel
• Remove a blanking plate from a spare PCI slot on the rear panel of the server. The PCI
slot must be wide enough to accommodate the external tape drive connector.
• Feed the external tape drive connector and cable through the empty slot from the
inside of the server.
1 To tape drive 2 To SAS controller 3 Not used
3. Connect the SAS cable inside the server and replace the cover
IMPORTANT:
On some servers, even those with latch-mounted arrangements, it is
necessary to use the supplied self-tapping screw to secure the blanking plate before
you replace the cover.
1 Host SAS controller (HBA) 2 SAS cable to hard disk bays 3 SAS Cable
Now go to "Options 2 and 3: Completing the installation"
Option 2: Connect to a spare internal port on the
host HBA (some HP ProLiant servers only)
The following instructions are valid ONLY IF you are connecting the external tape drive to
a spare internal connector on the host SAS controller.
This installation uses the HP Infiniband-style or mini-SAS split cable to connect to an internal
port on the host SAS controller. It requires a spare PCI slot to accommodate the cable
bracket and SAS connector to the tape drive. The cable must be purchased separately.
Refer to http://www.hp.com/go/connect to find out which cable is appropriate.
1 Infiniband-style connector found on many older ProLiants
2 Mini-SAS connector found on some ProLiants
TIP:
The CD-ROM contains a driver install package for Windows. We recommend
that you use the installer package to install the drivers
BEFORE
you connect the tape
drive.
1. Feed split SAS cable through the server rear panel
• Remove a blanking plate from a spare PCI slot on the rear panel of the server. The PCI
slot must be wide enough to accommodate the external tape drive connector.
• Feed the external tape drive connector and cable through the empty slot from the
inside of the server.
1 To tape drive 2 To SAS controller 3 Not used
2. Connect the SAS cable inside the server and replace the cover
IMPORTANT:
On some servers, even those with latch-mounted arrangements, it is
necessary to use the supplied self-tapping screw to secure the blanking plate before
you replace the cover.
1 Host SAS controller (HBA) 2 SAS cable to hard disk bays 3 SAS Cable
NOTE: This will leave unused cabling within the server because the ‘B’ connector is
not required in this configuration. Coil and secure the unused cabling so that it does
not interfere with other components inside the server.
