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.

I believe my initial post specified the correct order for the vary
commands. Anyway, glad we could help. We all like to avoid taking down
our systems unnecessarily.
