ADD POOL Command (Super Group Only)
cannot use ALTER POOL to change the search space attribute. To change an
existing pool’s search space attribute:
1. Use INFO TAPEVOLUME to find out the status of the tapes in the pool.
2. Use DELETE TAPEFILE and then DELETE TAPEVOLUME, if applicable, to
remove the pool entries for tapes of status assigned.
3. Use DELETE TAPEVOLUME to remove the pool entries for tapes of status
scratch, released, or bad.
4. After Steps 2 and 3, the pool is empty, and related file catalog entries are
erased. Delete the empty pool with DELETE POOL.
5. Re-create the pool with an ADD POOL command, using the correct
SEARCHSPACE value.
6. Add scratch tapes back to the pool with ADD TAPEVOLUME.
7. Add the essential assigned tapes (tapes containing unexpired files) back to the
pool with ADD TAPEFILE commands. ADD TAPEFILE also re-creates the
volume and file catalog entries.
Examples

To create a pool of open-reel tapes with ANSI labels and a density of 1600 bpi:
MC> ADD POOL TEST_TAPES,&
>>> VOLCAT MASTER_TAPE_CATALOG,&
>>> DENSITY 1600,&
>>> LABELS ANSI,&
>>> TYPE OPEN

This example creates a pool of cartridge tapes that are physically stored and used
in a tape library. A density value of ANY is used because cartridge tapes do not
have densities as open-reel tapes do.
MC> ADD POOL ACS_TAPES,&
>>> VOLCAT MASTER_TAPE_CATALOG,&
>>> DENSITY ANY,&
>>> LABELS ANSI,&
>>> TYPE CART3480
Note. This procedure is only reliable for a pool that does not include BACKUP tapes,
especially if it is an APPEND ON pool. You cannot use ADD TAPEFILE to add an
appended tapefile. ADD TAPEFILE does not recatalog DISKFILE entries for
CATALOGFILES ON BACKUPs. You should wait until ASSIGNED or FULL tapes expire or
are no longer needed and can be deleted without a need to add them back.
