That tells me that you allocated them correctly. The question is whether DSF
actually wrote CP-compatible blocks (which are different than what minidisks
use) on every cylinder.  That¹s one of the reasons why I always add paging
areas in full packs, and always run DSF on them, even if they¹re brand new
or already been formatted by Some Other OS.

>From the other conversation, you may have ended up with a minidisk
overlapping a paging area. In either case, you should reformat the disks in
question next time you IPL and have the system down for any period (can¹t do
it while it¹s up if pages have actually been written to the paging areas; CP
doesn¹t really give you an easy way to force migration of pages off a pack
if they are still referenced by something). Taking the problem volumes
offline and bringing the system up to the point of having OPERATOR logged in
but before AUTOLOG1 comes up would be one way to safely reformat them
without going to standalone DSF.

As Marcy said, though: you are very light on paging space for guests of the
size you describe. You probably should wheedle some more paging packs from
your storage guys.
