We have always backed up VM system packs to tape using DDR. With the
advent of Shark and flashcopies we are thinking about using flashcopy
instead. But that brings up the problem of duplicate volsers if we do the
entire pack. We are thinking of labeling the target volumes something
different from the system volsers and then flashing from 1 to end instead
of 0 to end. This will get around the duplicate volser, but do we lose
anything by not getting cylinder 0? Where are the pack allocation tables
kept? What problems might we run into by flashing back to the original
volume or if we have to flash to a totally different volume? Is it
possible to clip the target volume to the system volume names and just IPL
off that if need be? Any other recomendations?
It would certainly be nice for the flashcopy command to have another
parameter that could specify a new volser for the target volume so we could
flash 0 to end and not have the duplicate problem.
Thanks.
