AILURE TO OMMUNICATE WITH A
If you have a SCSI library, check the tape drive's installation on the SCSI bus,
described in "Connecting to SCSI" on page
If you have a Fibre Channel connection to your library (the tape drives
installed in the library are Fibre Channel), check the Fibre Channel
connection, described in
page 20.
If you have an Ethernet connection to your library, check the library's
Ethernet connection, described in
page 21.
If the ADI interface is not connected properly, it is possible that the tape
drive will not communicate on the SCSI bus (see
(same configuration)" on page
Use the Remote Management Utility (see
(see page 189) to capture the diagnostic logs from the library and the tape
drive(s) immediately after an error is reported by your backup software. See
"Advanced Troubleshooting" on page 202
can examine the log to determine the nature of the reported error.

Mark any cartridge that fails. If you notice that the same cartridge results in
multiple failures, replace the cartridge.
