ABACKUP: Preventing aggregate backup

Explanation: ABACKUP is an optional parameter specifying that the process of backing up aggregated data sets stops after completion of any currently running aggregate backup. Any ABACKUP commands not processed remain in the queue until ABACKUP is released.

Subparameter	Explanation
agname	ABACKUP(agname) is an optional parameter specifying an aggregate group. For agname, substitute the name of the SMS aggregate group.
EOD	ABACKUP EOD If the EOD option is specified with a HOLD ABACKUP command, the currently executing aggregate backup is stopped at the end of the data set currently processing, and the ABACKUP command is purged from the queue. All open data sets and tapes are closed and all allocated data sets and tapes are deallocated before the termination. The ABACKUP output files are uncataloged and the tape volume serial numbers are removed from the HSMABR tape volume set if they were indicated to be protected. During ABACKUP processing, if the control file has already been written and a HOLD EOD is issued, ABACKUP is allowed to complete normally. However, if ABACKUP was issued with the MOVE option, ABACKUP will be held. If an aggregate group name was specified with the HOLD ABACKUP command, the above processing only occurs when the specified name matches a currently running or pending ABACKUP command. If the ABACKUP parameter is specified with the HOLD command and without the EOD option, the currently executing ABACKUP commands run to completion. If an aggregate group name has been specified, subsequent commands for that name are held. When an aggregate group name was specified, the above processing only occurs if the specified name matches a currently running or pending ABACKUP command. Notes: If you issue an ABACKUP command with a WAIT option when ABACKUP is held, that request fails and an error message is issued. If you issue an ABACKUP command with a NOWAIT option when ABACKUP is held, that request is queued and processed when ABACKUP is released. To ensure data integrity, you should HOLD ABACKUP from processing aggregated data sets whose data is being heavily used, or when automatic functions are running.

Subparameter

Explanation

agname

ABACKUP(agname) is an optional parameter specifying an aggregate group. For agname, substitute the name of the SMS aggregate group.

EOD

ABACKUP EOD If the EOD option is specified with a HOLD ABACKUP command, the currently executing aggregate backup is stopped at the end of the data set currently processing, and the ABACKUP command is purged from the queue. All open data sets and tapes are closed and all allocated data sets and tapes are deallocated before the termination. The ABACKUP output files are uncataloged and the tape volume serial numbers are removed from the HSMABR tape volume set if they were indicated to be protected. During ABACKUP processing, if the control file has already been written and a HOLD EOD is issued, ABACKUP is allowed to complete normally. However, if ABACKUP was issued with the MOVE option, ABACKUP will be held. If an aggregate group name was specified with the HOLD ABACKUP command, the above processing only occurs when the specified name matches a currently running or pending ABACKUP command.

If the ABACKUP parameter is specified with the HOLD command and without the EOD option, the currently executing ABACKUP commands run to completion. If an aggregate group name has been specified, subsequent commands for that name are held. When an aggregate group name was specified, the above processing only occurs if the specified name matches a currently running or pending ABACKUP command.

Notes:

If you issue an ABACKUP command with a WAIT option when ABACKUP is held, that request fails and an error message is issued.
If you issue an ABACKUP command with a NOWAIT option when ABACKUP is held, that request is queued and processed when ABACKUP is released.
To ensure data integrity, you should HOLD ABACKUP from processing aggregated data sets whose data is being heavily used, or when automatic functions are running.

Defaults: None.
