Before you start

HP StorageWorks DAT models
This guide describes how to install and operate the following HP StorageWorks DAT rack-
mount tape drive models:
• HP StorageWorks DAT 72
• HP StorageWorks DAT 40
Which operating systems are supported?
HP StorageWorks DAT drives can be connected to servers running under Windows®,
NetWare, UNIX, Tru64 and Linux. Refer to the "HP StorageWorks Tape Software
Compatibility" topic on our World Wide Web site (
information about the operating system versions that are supported.
Which rackmount systems can I use?
HP StorageWorks DAT removable tape drives are used in conjunction with the
HP Tape Array 5300 system, which can be used with both full-height and half-height tape
drives. It will hold up to four HP StorageWorks DAT tape drives. The tape array is designed to
be installed into HP, IBM and other compatible 19" rackmount systems. It must be properly
installed and configured. Refer to your tape array documentation for further details.
Airflow requirements
The HP Tape Array 5300 is designed to provide adequate airflow for up to four half-height or
up to two full-height tape drives. As long as the tape array is fully populated, it will provide
adequate airflow for your HP StorageWorks DAT tape drives. If you have unused bays in the
tape array, you must install the blanking plates provided with the tape array. This ensures that
there is adequate airflow to the drives. See the documentation with the tape array for details
on installing blanking plates.
You should ensure that ventilation is adequate at the front and rear of the tape array.
How do I connect the drive to my server?
The following guidelines apply:
• For optimum performance the drive should be the only device on the SCSI bus.
• If you daisy-chain devices, make sure that devices are of the same SCSI type and that
each device on the same SCSI bus has a unique SCSI ID and is terminated appropriately.
Do not daisy-chain more than two devices on the same SCSI bus (for example, two LVD
Wide Ultra drives).
• Always terminate the SCSI bus.
• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller.
The individual tape drives are connected to their host server via the high density LVD/SE SCSI
connectors on the back of the tape array. They do not require any SCSI cables to plug into the
tape array. However, suitably-rated cabling and terminators are required to connect the tape
array with the SCSI host. You will need a properly installed and configured SCSI host bus
