4 Installing an external DAT tape drive
If you are installing an internal DAT tape drive, please refer to Chapter 3.
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 11 Setting 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.
