Table 8 EDLM Policy Settings

Note: To disable EDLM scanning policies on a partition, select
None for each of the following: Scan upon import, Scan
based on Tape Alert, and Use StorNext configuration. In
addition, set the normal and full scan time intervals to
zero.
Setting Description
General Settings
Allow concurrent scans Select the number of tape drives that this partition can use for EDLM scans
at any one time. If you have several partitions that will use EDLM scanning
drives, you can use this feature to divide the EDLM drive resources so that
a single partition with a large number of scans to perform can never “hog”
all of the resources and prevent other partitions from performing their
scans in a timely manner.
Choices are: Unlimited (default), 1, 2, 3, or 4. “Unlimited” means that this
partition can use all available EDLM scanning drives concurrently.
Report media
inaccessible
When this check box is de-selected (default), if a host requests a tape
cartridge that is being scanned, the scan is cancelled and the tape cartridge
is moved back to its original location to service the host request. The
interrupted scan is not rescheduled. The EDLM report indicates the
interruption or cancellation. This ensures that normal operations are not
affected by EDLM scanning.
When this check box is selected, if a host requests a tape cartridge while it
is being scanned, the library responds to the host that the tape cartridge is
inaccessible.
Note: This feature is currently disabled. The library always reports
media accessible to hosts (i.e., the box is de-selected and cannot be
selected).
