In this specific instance ("I wanna move a dedicated paging volume") wher
e
the data contained on the pack is purely ephemeral and only relevant unti
l
the next SHUTDOWN, it can be worthwhile to know that, once CP's recognise
d
a CP-OWNED volume at (usually) IPL time and added it to the CP-OWNED list
,
it has no reason to go back and re-read the volume serial number.
It is therefore perfectly straightforward to format and allocate a new
paging pack and then, via a minidisk definition covering cylinder zero of
the, "old" pack, relabel the, "old" pack without giving the currently-
running system any problems at all - it'll happily carry on paging to the
relabelled pack until SHUTDOWN time. If one format/allocates the new pack
with a dummy label and then runs the two relabel steps together using a
single file as input to ICKDSF then this reduces the, "window of
opportunity" when (neither or) both volumes have the, "magic" volser to
(usually) milliseconds.
