During all-member warm-start processing, the operator is notified of any spool volumes not mounted, and is requested to provide information concerning their status.If a spool volume cannot be recovered, the operator's response (PURGE) will force the purging of jobs and SYSOUT data sets allocated to the volume. If the operator indicates that the volume is only temporarily unavailable (GO), no jobs allocated to that volume will be processed until the volume is made available through a $S SPL command. If the required volumes have not been mounted at this point, the operator can end (QUIT) JES2 initialization.
