Use this page to add, modify, or delete Inhibit Reclaim
schedules used to postpone tape reclamation in a IBM® TS7700 cluster.
If the cluster does not possess a physical
library, the Inhibit Reclaim schedules page is not visible
on the IBM TS7700 management
interface.
Reclamation can improve tape utilization by consolidating data
on some physical volumes, but it consumes system resources and can
affect host access performance. The Inhibit Reclaim schedules function
can be used to disable reclamation in anticipation of increased host
access to physical volumes.
- Schedules
- The Schedules table displays the list of Inhibit Reclaim
schedules defined for each partition of the grid. It displays the
day, time, and duration of any scheduled reclamation interruption.
All inhibit reclaim dates and times are displayed first in Coordinated
Universal Time (UTC) and
then in local time.
Note: Prior to microcode level 8.5.0.xx, inhibit
reclaim schedules were designated using local time instead of UTC.
If you recently upgraded the TS7700 from
microcode level 8.4.0.xx or earlier, verify that your inhibit reclaim
schedule displays the correct day and time before starting an inhibit
reclaim operation using the new code version.

designations, or you can use the time chooser to select a start time
based on a 12–hour (AM/PM) clock.
- Local Day of Week

- Duration
- The number of days (D) hours (H) and minutes (M) that the reclamation
will be inhibited. The values in this field must take the form
