The server boots but does not recognize the autoloader
The application does not recognize the autoloader
The autoloader does not work
Possible reason Recommended action
The power or SCSI cable is not connected
properly.
Check that the cables to the autoloader are firmly
connected. Ensure that the SCSI cable does not have
any bent pins. Replace, if necessary. (Refer to the
www.hp.com/go/connect web site.)
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 autoloader’s SCSI ID address is not
unique.
Make sure that each device on the SCSI bus has a
unique ID.
We recommend that the HP StorageWorks DAT
autoloader is connected to a dedicated host bus
adapter. Do not connect the drive to a disk RAID
controller as this is not supported.
The autoloader was switched on after the
server booted up. The server only checks for
SCSI devices at power-on.
Switch on the autoloader and then reboot the server.
Possible reason Recommended action
The application does not support the
autoloader.
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 DAT autoloader. Load any service
packs as necessary.
Some applications require drivers to be
loaded.
Check that the correct SCSI and autoloader drivers are
installed. Consult the backup application’s installation
notes for details.
Possible reason Recommended action
If the drive does not power up, the power
cable may not be connected to the
autoloader properly.
Make sure that the power switch and LED are on and
that the power cables are firmly connected. If they are,
the device has probably failed. Call for service.
If the self-test fails, (Operator Attention
Light is steady amber), there may be a
hardware or firmware failure.
Power down the autoloader and power it up again. If
the self-test still fails, see “Understanding the OAR
LED” on page 43.
