Description
Scans a tape if the time interval since the last scan was performed has
been exceeded. In the text box, type a time interval (in days) after which
a scan will be performed.
Note: When deciding on the interval, consider the number of tapes to
be scanned in the entire library, as well as the type of scan to be
performed. Full scans can take more than 2 hours on full tapes.
Over-scheduling can cause delays or tapes not to be scanned as
intended.
This policy is disabled by default. The default interval is 180 days. To
change the interval, type a new value in the interval text box.
A suspect count is a means by which an external application determines
when to stop writing data to tape.
If you select this policy, a tape will be queued for EDLM testing when its
suspect count threshold is reached. If the EDLM test indicates the tape is
good, you can reset the suspect count on the external application and
continue to use the tape. For more information on suspect counts and
resetting suspect counts, refer to your external application's
documentation.
This policy is disabled by default. You can only select this policy if Enable
