For my first z/OS 3.1 IPL (under z/VM) I got WAIT 006. After a long search I found z/VM APAR VM66721: Z/OS GUEST IPLS FAIL AFTER APPLYING UJ92591/UJ92728. There is no PTF as yet but there is a work-around (turn off mini-disk caching).
Those PTFa are the validated boot PTFs for z/OS 2.5 - the function is incorporated into z/os 3.1. I have no idea why the failure occurs but I thought maybe z/os is using some I/o command sequence which z/Vm does not support properly. That got me worrying about whether z/OS 3.1 (or 2.5 with the validated boot PTFs) will work on old hardware, specifically DS6800 which we have at a backup site. Our 3.1 test under z/Vm used DS8884. Has anyone tried running 3.1 (or 2.5 with the validated boot PTFs), or have any understanding of why an IPL may fail on DS6800 ?. We are not using validated boot and have no intention of doing so.
