4 Installing an external DAT tape
drive
If you are installing an internal DAT tape drive, please refer to
“ Installing an internal DAT tape drive ” on page 19.
If you are installing a removable DAT tape drive, please refer to
“ Installing a removable DAT tape drive ” on page 33.
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.
Figure 12 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
“ Diagnostic tools ” on page 55). This will provide information about the SCSI bus and the SCSI
IDs in use.
The UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM also contains instructions on
how to determine the SCSI IDs of existing devices on UNIX servers.
2. Change the tape drive’s SCSI ID, if necessary.
