ALTER POOL Command (Super Group Only)
ALTER POOL Command (Super Group Only)
ALTER POOL changes one or more attributes of an existing pool. If the new attribute
conflicts with any tape in the pool, the attribute is not changed. The conflicting tapes
must be removed from the pool with DELETE TAPEVOLUME (for scratch tapes) or
DELETE TAPEFILE, and then DELETE TAPEVOLUME (for assigned tapes) before
you rerun ALTER POOL.
You cannot change the search space attribute with this command. For a method to
change it, see Considerations on page 2-55.
Once a pool is established as append capable or not append capable, it cannot be
changed with subsequent ALTER POOL command unless the pool is empty or all of
the tape volumes of LABELS BACKUP are SCRATCH.
pool-name
is the logical name of the pool.
VOLCAT \node.volume-catalog-name
is the logical name of the volume catalog that owns the pool. Include \node when
the volume catalog is not on your current default node.
APPEND { ON | OFF }
designates whether tape volumes known to the pool can contain multiple tape files.
NOTE: APPEND is not allowed on open-reel tape drives since this drive type does
not have the technology needed to support APPEND. Hence, the option APPEND
ON has no effect when specified for TYPE OPEN.
