If there are empty bays, insert a blanking plate. This is essential to ensure adequate airflow is

maintained. Failure to do so may affect tape drive performance.
See the documentation with the tape array for details on installing blanking plates.

Set the drive’s SCSI ID

To set the tape drive’s SCSI ID you need to set the appropriate switch on the rear of the tape array. The

number of address switches corresponds to the number of tape drives that can be inserted into the

tape array.
Each device on the SCSI bus must have a unique SCSI ID.

For HP ProLiant servers where the tape drive is connected to the built-in SCSI bus, we recommend

that the tape drive is assigned a SCSI ID between 1 and 6.

For all other servers and when used with separate HBAs, 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.

Typically, the HP Tape Array may hold up to four tape drives where each drive is attached to a separate

server. Under this configuration, the SCSI IDs of each tape drive will not conflict with each other as they

are each installed onto a separate SCSI bus. This is the recommended configuration for Ultra320 devices,

such as the Ultrium 1840 and Ultrium 960 tape drives.
If you daisy-chain devices make sure that the devices are of the same SCSI type and that each device on

the same SCSI bus has a unique SCSI ID. Do not daisy-chain more than two devices on the same SCSI

bus and make sure that the end device is terminated. Do not mix drive families (only daisy-chain with

other Ultrium tape drives) and do not put Ultra160 drives on the same bus as any Ultra320 device.

1.

Decide which SCSI ID to use.
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 computer’s current SCSI configuration (see

Diagnostic tools

” on page 57). 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 provides

instructions on how to determine the SCSI IDs of existing devices.
