OK, I an certifiably confused. Or: "Insufficient Data".
To cut/paste:
---<snip>---
Our production system is a guest system under z/VM 5.1. I don't know if
this would matter in the explanation as to why the system had a 55% paging
space utilization...
...

Cecelia,
Do you mean that the QUERY ALLOC PAGE was issued from your 510 1st-level
system, and you are concerned about the volume:
EXTENT EXTENT TOTAL PAGES HIGH %
VOLID RDEV START END PAGES IN USE PAGE USED
------ ---- ---------- ---------- ------ ------ ------ ----
510PAG F005 1 3338 600840 333053 443499 55%
Or do you mean that you are concerned about the complete lack of paging on
PAG002 and PAG003?
If the command was issued on the 1st level system, and PAG002 and PAG003
are attached to the 2nd level system, then why are they showing up on the
1st level system?
Can you share with us
1) which DASD are expected to be used by which system?
2) the "CP_OWNED" statements that have those three volsers (510PAG,
PAG002, and PAG003) on both the 1st and 2nd level systems (if they appear
in both).
3) The lines from the reply to "CP QUERY CPOWNED" for those three DASD on
both the 1st and 2nd level systems.
Thanks.

Sure, I'm find with not using cylinder 0. But this one looked strange to
me.

I certainly had not read in her post that this was a 2nd level system.
That makes for a completely different ball park.
