DFSMS/MVS is not at the proper release level to perform the tasks necessary to complete the function.
If the required level of DFSMS/MVS is not installed, aggregate backup is held. Aggregate recovery can run with a lower release level of DFSMS/MVS installed than aggregate backup. If the level of DFSMS/MVS required to run aggregate recovery is not installed, both aggregate backup and recovery are disabled. When aggregate backup and recovery are disabled, subsequent ABACKUP, ARECOVER, and DEFINE ARPOOL commands fail and DFSMShsm processing continues without ABARS.
If the message reads AGGREGATE BACKUP IS HELD, do not issue any ABACKUP commands until the proper level of DFSMS/MVS is installed. If the message reads FUNCTIONS ARE DISABLED, do not issue any ABACKUP or ARECOVER commands until the proper level of DFSMS/MVS is installed.
