If you create a scratch pool, be aware of the following conditions:

• If the scratch pool contains assigned volumes, these volumes remain in the scratch pool.

  NetBackup does not move assigned volumes to other pools as it does with unassigned volumes.

• NetBackup does not assign volumes while they are in a scratch pool.

  For example if a NetBackup policy or schedule specifies the scratch pool, all requests for those volumes are denied.

• NetBackup returns expired media to the scratch volume pool automatically (media that is returned must have been originally in the same scratch pool).

• To use NetBackup to manage the allocation of volumes to volume pools, do the following:

  • Create volume pools as required, but do not add any volumes to the pools.

  • Define a scratch pool and add all of the volumes to it. NetBackup moves volumes to the other pools as volumes are needed.
