The server boots but does not recognize the tape drive Possible reason The power or SCSI cable is not connected properly. The SCSI bus is not terminated correctly. The tape drive's SCSI ID address is not unique. Recommended action Check that the cables to the tape drive are firmly connected. Ensure that the SCSI cable is LVDScompliant and does not have any bent pins. Replace, if necessary. (See the "ordering supplies" topic on the HP StorageWorks Tape CD-ROM.) Check that the SCSI bus is actively terminated. (Refer also to the documentation for your SCSI controller and any other SCSI devices you may have.) Make sure that each device on the SCSI bus has a unique ID. We recommend that the tape drive is connected to a dedicated host bus adapter. Do not attach the drive to the same SCSI bus as your disk drive, or to a RAID controller. The application does not recognize the tape drive Possible reason The application does not support the tape drive. Some applications require drivers to be loaded. Recommended action Use HP Library & Tape Tools to check that the drive is installed properly. Refer to our World Wide Web site (www.hp.com/go/connect) for details of backup applications that support the HP StorageWorks SDLT 600 tape drive. Load any service packs as necessary.

The server boots but does not recognize the tape drive
The application does not recognize the tape drive
The drive does not work
Possible reason
Recommended action
The power or SCSI cable is not connected
properly.
Check that the cables to the tape drive are firmly
connected. Ensure that the SCSI cable is LVDS-
compliant and does not have any bent pins.
Replace, if necessary. (See the “ordering supplies”
topic on the
HP StorageWorks Tape
CD-ROM.)
The SCSI bus is not terminated correctly.
Check that the SCSI bus is actively terminated. (Refer
also to the documentation for your SCSI controller
and any other SCSI devices you may have.)
The tape drive’s SCSI ID address is not
unique.
Make sure that each device on the SCSI bus has a
unique ID.
We recommend that the tape drive is connected to a
dedicated host bus adapter. Do not attach the drive
to the same SCSI bus as your disk drive, or to a RAID
controller.
Possible reason
Recommended action
The application does not support the tape
drive.
Use HP Library & Tape Tools to check that the drive
is installed properly. Refer to our World Wide Web
site (
www.hp.com/go/connect
) for details of
backup applications that support the
HP StorageWorks SDLT 600 tape drive. Load any
service packs as necessary.
Some applications require drivers to be
loaded.
Check that the correct SCSI and tape drive drivers
are installed. Consult the backup application’s
installation notes for details.
Possible reason
Recommended action
If the drive does not power up (all LEDs are
off), the power cable may not be connected
to the drive properly.
Make sure that the power cable is firmly connected.
If it is, try another power connector. If the drive still
does not power up, call for assistance.
If the self-test fails (see “LEDs during self-test”
on page 41), there may be a hardware or
firmware failure.
If there is a cartridge in the drive, remove it. Power
down the drive and power it up again. Try another
power connector. If the self-test still fails, call for
assistance.
