Hi Crispin,
The intent was to prevent CP-owned volumes from being the TARGET of a
FlashCopy relationship, as it means there's another "writer" of data to
the pack that CP will be using and Bad Things will surely result. If your
pack is a SOURCE in the FlashCopy relationship, then I suspect we would
throw a cautionary message out at IPL and let the system operator decide
whether to ignore it or withdraw the relationship. If that is not
happening, then it sounds like a service call to us is warranted.
Regards,
Eric

Flashcopy Relationships and CP Owned packs.
Can anyone explain why it is thought to be a bad idea to form Flashcopy
relationships with CP owned disks. As I found out this morning , it cause
hard wait of z/VM ! I want to have a Flashcopy relationship of P30RES for
backup as it only take couple of second to do compared to 3 minutes with
full flashcopy.
