XP1024 Flashcopies on mainframe

[Christopher Powers]

We have zSeries mainframes and an XP1024 DASD controller. On one mainframe we currently run weekend FlashCopy jobs of numerous volumes after the CICS, DB2, and IMS systems are shutdown prior to IPL. After IPL the targets are backed up to stacked tapes as disaster recover backups. Since all of the DB2 and IMS databases have now been migrated to virtual tape image copy backups and will be restored for disaster recovery tests via these image copies, the associated DB2 and IMS database disk volumes are being removed from the Flashcopies. A current project is to move from weekly IPL's to on-request IPL's. For the non-IPL weekends, since the CICS, DB2, and IMS subsystems will NOT be shutdown, will the remaining FlashCopy backups of the CICS, DB2, and IMS system disk volumes be OK, or will they be 'fuzzy' and possibly have issues for disaster recovery testing? Note: Flashcopies use ADRDSSU parms COPY FULL, ALLD(*), ALLX, DUMPCONDITIONING, PURGE, WRITECHECK, ADMIN, and the tape dumps use DUMP FULL, ALLD(*), ALLX, OPT(4), ADMIN. Thanks for any feedback!
