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.
