Agent information 61
Having a large number of retry corrected errors does not necessarily indicate that the drive is failing. However,
as a precaution, replace a drive that has an abnormally high amount of errors when compared to similar drives.
If this count increases rapidly, you might need to clean or replace the drive.
• Uncorrectable—Displays the number of read errors that could not be recovered by a tape drive’s ECC
algorithm, retries, or any other recovery mechanism. Over time, a drive might produce these errors. These errors
are usually caused by bad media sections on the tape.
• Tape Drive Heads Need Cleaning—Indicates the tape heads on the drive must be cleaned. If they must be
cleaned, a cleaning tape must be placed in the drive or the autoloader.
NOTE: A value of Not Supported indicates that the tape drive does not support this feature. You might need to
upgrade your firmware to the latest revision.
As routine maintenance, the drive heads should be cleaned according to the recommended schedule for your
specific drive.
• Cleaning Tape Needs Replacement—Indicates the cleaning tape associated with the autoloader is at the end of
the tape. If the cleaning tape is at the end of the tape, a new cleaning tape must be placed in the autoloader.
NOTE: A value of “Not Supported” indicates that the tape drive does not support this feature. You might need
to upgrade your firmware to the latest revision.
• Number of Cleanings Performed—Indicates the number of times that the tape drive has been cleaned. If a tape
drive is cleaned too much it can damage the tape heads.
NOTE: A value of Not Supported indicates that the tape drive does not support this feature.
