Step 2: Check the drive's SCSI ID Your HP StorageWorks SDLT 600 drive is shipped with a default SCSI ID of 6, but it 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. 1 Determine whether you need to change the SCSI ID from the default of 6. For example, in multiinitiator parallel SCSI environments (such as ProLiant clusters) it is possible that the initiator devices will use IDs 6 and 7. In this case, you will need to change the tape drive's SCSI ID. For most operating systems you can install HP Library & Tape Tools from the link on the HP StorageWorks Tape CD-ROM and run the "Install Check" to check your server's current SCSI configuration (see page 29). This will provide information about the SCSI bus and the SCSI IDs in use. For UNIX systems, check the UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM for instructions on how to determine the SCSI IDs of existing devices. 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. 2 Note Change the tape drive's SCSI ID, if necessary. Use a small screwdriver or a ball-point pen to press the indented SCSI ID selector buttons on the rear panel (see Figure 4) until the required value is displayed. Do not use a pencil because small bits of graphite could contaminate the drive. The server and the tape drive SCSI IDs are only checked at power-on. To change the SCSI ID after installation, power down both the server and the tape drive, change the tape drive's SCSI ID, power up the tape drive, and then power up the server. 13
