Your backup software may report an error as a result of a failure to
communicate with the tape drive(s) or library, a failure by a tape drive to write
or read data, or because of a software configuration issue.

Communication problems on the SCSI bus may be reported by the backup
application as resets, a loss of communication with a tape drive, failure to
detect a tape drive, I/O device errors, or parity errors. These types of errors
may occur intermittently.
If you have a SCSI library, check the tape drive’s installation on the SCSI bus,
described in
“Connecting to SCSI” on page 17 .
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
“Connecting the Library to Fibre Channel” on
page 20 .
If you have an Ethernet connection to your library, check the library’s
Ethernet connection, described in
“Connecting the Library to Ethernet” on
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
“Replacing a Tape Drive
(same configuration)” on page 165 ).
Use the Remote Management Utility (see “Logs” on page 111 ) and LTOTool
(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 for information. Technical Support
can examine the log to determine the nature of the reported error.

If your backup software reports a media error, one of the following situations
may have occurred:
The tape drive needs cleaning (see “Cleaning the Tape Drive” on page 128 ).
Always try cleaning the tape drive before you assume the cartridge is bad.
Be sure to use an LTO Cleaning Cartridge.
The cartridge needs to be replaced. Try using a different cartridge for the
backup, making sure that the tape is not written in an unsupported format.
Mark any cartridge that fails. If you notice that the same cartridge results in
multiple failures, replace the cartridge.
