Step 1: Check The Scsi Connection - HP 330834-B21 - StorageWorks Ultrium 460 Tape Library Drive Module Getting Started Manual

Step 1: Check the SCSI connection

Use the following questions to help you check your SCSI connection. Most users can use HP
Library & Tape Tools to check the SCSI bus, 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 Does the SCSI bus type
match the drive type, Ultra
320 for Ultrium 960, Ultra
160 for Ultrium 460, Ultra 2
for Ultrium 230?
(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.
SCSI Bus Type

table 1: supported SCSI bus types
Note If you attach your drive to a higher-rated SCSI bus, the internal SCSI cable should be of the
same specification as the SCSI HBA. For example, if you connect an Ultrium 460 to an Ultra
320 bus, make sure that the internal cable supports Ultra 320.
