Issuing the $P SPOOL command allows all work on the spool volume to be processed and prevents any available space from being allocated by new work. You may also cancel and purge all jobs residing on a volume using the CANCEL parameter. If you cancel all work for an inactive volume, JES2 deletes any work remaining on the volume. This could result in lost spool space on other volumes if the jobs on the volume being cancelled have allocated space on other volumes. All other job resources will be recovered. The lost spool space will be recovered upon an all-member warm start if you include SPOOL=VALIDATE as a restart option or automatically within 7 days as provided by the automatic spool reclamation function, whichever occurs first. If the volume can be remounted, you may start it to prevent the loss of spool space by issuing the $S SPOOL,CANCEL,P command.
