We have had card issues with our array also. We just vary

back on.
But Richard has the right of it: VARY OFF PATH xx FROM ALL, then VARY OFF
CHPID xx. Never pull the chpid out from under CP without warning.
I played with this in our test lpar. z/VM 5.1 does not let you vary off
the chpid before varying off the path. Also, it is not possible to vary
off all the chpids. z/VM wants (understandably!) at least one path to
the volumes that are online. We performed the card swap successfully
after varying off the paths and the chpids and then varying them back on.
I want to thank all on this mailing list who have been very helpful.
Rock on z/VMers!
It's
like Uncle Charlie's parlor trick of pulling the tablecloth out from under
the dishes: the odds of success are low and you risk breaking the dishes.
