HP Servers Troubleshooting Guide
continued
Possible Cause
Tape is not compatible
with the drive.
Device conflict exists.
SCSI terminator is
missing for the external
DLT drive.
Maximum number of
drives per controller has
been exceeded.
Problem exists with a
DAT drive.
Non-failure error has
occurred.
Possible Solution
Check your tape specifications to be sure
that the tape is designed to work with the
drive.
Be sure that each device on the
controller has a unique ID. Use the
server setup utility to check for conflicts.
The external DLT drive requires a SCSI
terminator to be secured to the unused
SCSI IN connector on the back of the
drive. DLT drives can be daisy chained.
Do not connect more than three units per
SCSI controller. The last DLT drive in the
chain requires the SCSI terminator. If the
terminator is not connected, the system
may not recognize the DLT drive.
Refer to your controller documentation.
Refer to "DAT Drives" in this chapter.
Some errors do not cause a failure. If an
error occurs but does not disrupt the
backup, you may be able to ignore the
error. Contact the software vendor for
more information about the message.
