Volume allocation from the volume pool

When VOLUMES=*FROM-POOL is specified, the volumes are taken from the volume pool of the archive which has been created in the directory. If no volume pool has been created or this pool is exhausted, the tapes are allocated from an assigned MAREN pool using MAREN.

If both pools are exhausted, the volumes are requested from the operator as with VOLUMES=*FROM-OPERATOR.

When volumes are released these remain allocated to the ARCHIVE and are available for repeated use.

Management of the volume pool is described in section "Volume pool management".
