3 Installing an internal DAT tape drive If you are installing an external DAT tape drive, please refer to "Installing an external DAT tape drive" on page 29. 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. 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 3 Checking the SCSI ID 1. Determine whether you need to change the SCSI ID from the default of 3. DAT SCSI Tape Drives 19

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.
