Troubleshooting Common Problems
The library is not efficiently
backing up data.
• Check the network bandwidth from the host computer if
backing up data over the network.
• Check that the library’s drive(s) are on their own SCSI
bus and not daisy-chained to another tape drive or the
hard drive.
• Ensure that the drive is clean. See page 3-16 for more
information on cleaning the drive.
• Try a new tape. A marginal tape can cause performance
problems due to bad spots on the tape requiring retries.
• Ensure that the backup software is using fixed-length
records (or blocks) to maximize throughput and has not
defaulted to a smaller record size.
• Ensure that the data is being compressed.
• Check the size of the files. A large number of small files
can impact performance.
Operations
Need to abort internal test
cycle.
Press
[STOP]. The current test loop completes, then the test
stops.
Cannot write to the tape. • Check the write-protect tab on the tape to ensure it is set
to write-enabled.
• Check the host device file system access permissions.
• Verify that you are using the correct tape type.
• Check the
Drive Event Log for this drive.
• Check the drive/media log on the remote management
card report page.
• Try a new tape.
CAUTION: In the testing process, do not put the tape in
question into another drive since damaged tapes can damage
a drive.
