Host Settings on the Library
Choose whether to scan tapes as soon as they are imported into this
partition; and, if so, which type of scan to perform. This policy is disabled
by default.
Choices are:
• None (default) — Does not scan upon import.
• Quick — Does not scan the tape. Evaluates data from the cartridge
memory (CM) only. 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 — Evaluates the cartridge memory (CM) and scans selected
portions of the tape, focusing on areas most likely to indicate problems.
Takes up to 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 — Evaluates the cartridge memory (CM) and scans the entire tape.
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 offsite 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.
