There is an error code on the
LCD
Look up the error code, try to resolve the failure, and power cycle.
See
Chapter 4, “Event Codes and Acronyms.”
Performance
Poor throughput performance • Try a new tape. A marginal tape can cause performance problems due to bad
spots on the tape requiring retries.
• Backing up data that compresses poorly or is already compressed will lower
performance.
• Check the size of the files. Small file size can impact performance.
• Confirm that the backup application is utilizing block sizes of at least 32KB,
preferably 64KB. Refer to the backup application documentation for details.
• Check the network bandwidth from the host computer. If you are backing up
data over a network, consider comparing to a local-only backup.
• Make sure the backup server has enough memory to handle the bandwidth of
the backup or restore.
• Clean the tape drive with OCP or RMI.
Cleaning
Cannot load the cleaning
cartridge
• Make sure you are using an Ultrium universal cleaning cartridge.
• Contact your service representative.
Media
Cleaning or data tape
incompatible with drive.
Cleaning or data tape incompatible with drive.
Cannot write to or read from
tape.
• Make sure that the tape is write enabled (move the write-protect switch to the
enabled position).
• Make sure you have the appropriate data tape for your library model.
• Make sure you are using an Ultrium tape that has not been degaussed. Do not
degauss Ultrium tapes.
• Make sure that the tape has not been exposed to harsh environmental or
electrical conditions and is not physically damaged in any way.
• Many backup applications do not read or write to tapes that were created using
a different backup application. In this case, perform an erase, format, or label
operation on the tape.
• Make sure you understand any data protection or overwrite protection schemes
that your backup application may be using, which could prevent you from writing
to a given tape.
• Retry the operation with a different, known good tape.
• Clean the tape drive with OCP or RMI.
<Media Attention> LED issues
Contamination by loose debris. Avoid contamination by ensuring that the library is installed in a clean,
contamination-free environment. Tapes should be stored vertically in their plastic
cases. Continue cleaning the tape drive as needed.
Non-acclimated media.
A tape should be acclimated for at least 24 hours before being used, particularly
if it has been stored at a substantially different temperature or level of humidity
than the library.
Tape cartridge is incompatible. Use only tapes that are compatible with the tape drive type.
Expired cleaning cartridge.
Make sure you are using an Ultrium universal cleaning tape. (max. 50 cleans)
