tapes, choose a scan type from the Select All Scan Type drop-down
list. The scan types are described in the following table.
Note: When deciding on the type of test to run, consider how the
tapes are being used. Depending on the number of EDLM
drives and the test type you choose, scans can take a very
long time to complete.
Type of Scan Description
Quick Does not scan the tape. Evaluates data from the cartridge memory (CM) only.
A quick scan takes less than one minute per tape.
Examples of when to use a quick scan:
• When you first import previously used scratch tapes into the library.
• When you import data cartridges that have been used in other backup and
archival environments and need to do a quick check to determine whether the
tape cartridge is nearing end of life, at end of life, or may have had issues
reading or writing.
Normal (default) Evaluates the cartridge memory (CM) and scans selected portions of the tape,
focusing on areas most likely to indicate problems.
A normal scan can take 20 minutes per tape.
Examples of when to use a normal scan:
• For tapes in frequent use within the library, with scanning triggered by drive-
reported media Tape Alert events.
• For tapes in frequent use within the library, with scanning being performed at
regular time intervals.
