Dear All, Funny, you asked this question today. I just experienced yesterday at the D/R site the same event. The page volumes were initialized with no page allocation causing the system to fail - HCP3000IE Catastrophic System Failure - REIPL the system. The error code is PGT004. I've to frantically detach the page volumes and reallocate them as page using cpfmtxa and had to add another spool because of the dumps. Since the SYSTEM CONFIG file 'auto warm start' statement, there is no cold start at Ipl.
You don't have to PPRC the page volumes but make sure that page allocation or page volumes are in place.

The reason is that I have a configuration with two DS-8000 where the page datasets are spread all over those two machines. DS-1 has the sysres, spool, and some page datasets and DS-2 it has additional page datasets. The system disks are mirrored by PPRC. So in case DS-1 will become unavailable I can continue on DS-2. This will be disruptive of course. Since the page datasets consume a lot of addresses we don't mirror them. In case DS-2 would become unavailable, would z/VM then crash? Would it be better to have all CPOwned volumes on one DS-8000 or can my current configuration remain as it is? Any opinion is appreciated very much. Furthermore I would like to ask if the new version of z/VM will allow emptying a page dataset in order to drain it and detach it without IPL. I just experienced that a drain of that volume not really helps. Thank you very much in advance. Kind regards, Fox This email is intended for the recipient only.
