Dear all, I am wondering about the reaction of z/VM in case it would lose one or two page datasets.
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
