HP StorageWorks DAT Internal Autoloader Getting Started Guide

Step 1: Check the autoloader’s SCSI ID

Note Your HP StorageWorks DAT autoloader is shipped with a default SCSI ID of 5. Each device on

the SCSI bus must have a unique SCSI ID number. The autoloader 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

autoloader 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 autoloader from its bag.

1 Determine whether you need to change the SCSI ID from the default of 5.

For many operating systems you can install HP Library & Tape Tools from the

HP StorageWorks Tape CD-ROM and run the “Install Check” to check your server’s current

SCSI configuration (see page 43). 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 autoloader’s SCSI ID, if necessary.

The SCSI ID is set using jumpers on a set of pins at the rear of the device, as shown in figure

3. Use tweezers or small pliers to move the jumpers to the pattern corresponding to the ID you

want. Do not remove the TP jumper. It should always be set.

Spare jumpers will be attached to the device.
