Step 1: Check 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. Most users can use HP Library & Tape Tools
to check the SCSI bus type, see page 33. 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
1 Is there a spare SCSI port on
the server's internal SCSI
bus?
2 Are the SCSI ribbon cable
and HBA card rated at Ultra
3 (160) or Ultra 4 (320)?
(Make sure the ribbon cable
is terminated. See page 19.)
3 Will the drive be the only
device on the bus? This is the
recommended configuration.
Do not connect to a RAID
controller channel.
4 You are ready to install the
drive.

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. See
table below. Consider replacing your
card with one of the recommended
HBAs. We recommend a 64-bit Ultra 3
(160) SCSI HBA kit.
Consider installing (if you have a spare
PCI slot) or replacing your card with an
Ultra 4 (320) HBA.
Supported
Yes. This is a recommended configuration.
Yes. This is a recommended configuration.
Yes, but this is not recommended
Yes, but this is not recommended as it will restrict
performance. Do not connect to a narrow SCSI bus.
No. The drive will not work and you may damage
the drive or controller
