Hello Clovis,
The PAGE DASD is one of the 5 3390-3 that was initialized as part of the sysres
pack when z/VM 6.1 was installed. I have not manually any additional ones to
this LPAR.
We have 2 sysres pack (DVxxxA and DVxxxB ) which serve as active and
alternates system volumes. Current active one is DVxxxA set (E100-E104) and
DVPAGB is the page volume that's part of the current alternates. I do
understand that we do not need to have a dedicated PAGE volumes as part of the
sysres since its just used for paging but this is the setup we follow here. I
do plan to user the alternate PAGE volume so as to give the system some more
PAGE space.
PAGE DVPAGA volume is in the system config and attached to the system, cp q
alloc does not show any page space on DVPAGA. I do not understand y. Can I
display the allocation table of a volume attached to the system? Even though
the PAGE volume is not being used I do not want to detach the PAGE volume in
fear of causing a crash.
Regards,
Ashwin

Subject: Re: Page volume not recognized after IPL
Hello, Ashwin:
For the dasd to be recognized it must be formated AND allocated as PAGE with
CPFMTXA, AND must be defined as Owned into SYSTEM CONFIG.
Is the DVRESB a new Page dasd?
To check dynamically, use these commands:
CP DEFine CPOWN SLOT 6 DVRESB
followed by other CP QUERY ALLOC
If the Query shows the page area, the problem is in the SYSTEM CONFIG. If not,
the problem was with CPFMTXA.

Page volume not recognized after IPL

We have recently ipl'ed one of our test z/VM 6.1 system off the our alternate
sysres pack. The system does not seem to recognize the page volume. Is there
something I did not configure?
I am ready to add another page volume to make sure that it does not ABEND due
to lack of page space. I will check the allocation on the PAGE volume after I
add some PAGE DASD.
Thank you,
Ashwin Bhemidhi
