HP DAT 40e Getting Started Manual page 36

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.
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.
The drive does not work
Possible reason
If the drive does not power up (both LEDs
and Power On LED are off), the power cable
may not be connected to the drive properly.
If the self-test fails (both LEDs are off, but
Power On LED is on), there may be a
hardware or firmware failure.
There is a hard error on the drive.

Recommended action
Check that the cables to the tape drive are firmly
connected. Ensure that the SCSI cable does not have
any bent pins. Replace, if necessary.
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 connected to the SCSI
controller has a unique SCSI ID. Remember that 7 is
normally reserved for the host bus adapter. (Users of
most operating systems can run HP Library & Tape
Tools to check the SCSI IDs of each device attached
to the SCSI bus, see page 29.)
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
backup applications that support the
HP StorageWorks DAT tape drive. Load any service
packs as necessary.
Check that the correct SCSI and tape drive drivers
are installed. Consult the backup application's
installation notes for details.
Recommended action
If the Power On LED is not on, check the power cable
connection and replace the cable if necessary. You
can use the power cable from your monitor or
another device to check that the connection is
working.
If the power supply is present and all LEDs remain
off, call for service.
If there is a cartridge in the drive, remove it. Power
down the drive and power it up again. If the self-test
still fails, call for service.
The Media Caution (Clean) LED shows steady amber.
Try powering the system off and then on again. If the
error condition signal still shows, call for service.
