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 www.hp.com/go/connect.
1Is there a spare SCSI port on the server’s internal SCSI bus?
Yes?
2Does 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.)
Yes?
3Will the drive be the only device on the bus? This is the recommended configuration. Do not connect to a RAID controller channel.
No?
No?
No?
Purchase and install one of the recommended HBAs into an unused 
Performance may be impaired. 
Consider replacing your card with one of the recommended HBAs. See table below.
Performance may be impaired, depending upon the tape drive model and SCSI bus. Ultrium 960 drives 
should always be on a dedicated bus. See table below.
