Reducing the time to reclaim tape volumes with high capacity

When a storage pool uses tape volumes with high capacity, reclamation processes might run for a long time if the drives are relatively slow at positioning tapes. There are steps that you can take to reduce overall process time.

To help reduce overall process time:

1. Set up the storage pool hierarchy so that the tape storage pool is the next storage pool for a storage pool that uses either a DISK device type or a FILE device type.
2. When you need to reclaim volumes, move data from the tape storage pool to the DISK or FILE storage pool.
3. Allow the data to migrate from the DISK or FILE storage pool back to the tape storage pool by adjusting the migration thresholds.
