All-member warm start

An all-member warm start is performed if a warm start is specified by the operator and JES2 determines that no other members of the configuration are active or there is only one member in the configuration. All in-process work in the MAS will be recovered. After an all-member warm start, other members entering the configuration for the first time will perform a quick start.

This is the only time that certain activities are performed within the MAS, because no other processors are currently using the checkpoint data set. These activities include:

Rebuilding the track allocation status (track group map) if you specify SPOOL=VALIDATE as a start option.
Validating (and rebuilding when necessary) the job and output queues and the job queue index. Damaged or corrupted job output elements (JOEs) and job queue elements (JQEs) are placed on the rebuild queue.
Deleting spool volumes not previously removed through the $P or $Z commands that are no longer available to the member. See Starting the multi-access SPOOL configuration for starting JES2 in a multi-access spool configuration.

Note: You can add members of a multi-access spool configuration at any JES2 warm start.
