Or FLASHCOPY. Be sure your "template" pack has a volser that is recognizably "garbage". E.g. 000000 or SCRTCH. Something you recognize as "available" or "unused". On a related note, keep an eye out for our FlashCopy SE (Space Efficient) support coming to a theater near you in time for Christmas. It will make this and a lot of other disk-related activities easier: - Copies that only contain changes (h/w-based union mount) - Ability to throw away the changes with a single command - Instantaneous copies useful when you want to backup the volume, but without the time delay and consumption of disk storage that you would have with 'traditional' FlashCopy. - The ability to specify a new label when you FlashCopy a volume (also available with traditional FlashCopy) - And more...
