Description
Quick Scan
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 Scan
(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.
Full Scan
Evaluates the cartridge memory (CM) and scans the entire tape.
A full scan can take more than 2 hours on a full tape.
Example of when to use a full scan:
• When tape cartridges are accessed infrequently and are used primarily for on-
site or off-site long-term data retention.
• When tape cartridges with valuable data are introduced into the library and the
state and condition of the tapes are unknown.
