3 Installing an internal DAT tape drive
If you are installing an external DAT tape drive, please refer to Chapter 4.
If you are installing a removable DAT tape drive, please refer to Chapter 5.
Check the drive’s SCSI ID
Your HP StorageWorks DAT drive is shipped with a default SCSI ID of 3. Each device on the SCSI
bus must have an unique SCSI ID number. The drive 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.
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.
Figure 2 Checking the SCSI ID
1. Determine whether you need to change the SCSI ID from the default of 3.
For many operating systems you can install and run HP Library & Tape Tools from the
HP StorageWorks Tape CD-ROM to check your server’s current SCSI configuration (see
page 49). This will provide information about the SCSI bus and the SCSI IDs in use.
