This was just posted on MXG-L by Chuck Hopf. I told him that I would post it here and he said go ahead. When he posts the APAR on MXG-L I'll post that here also.
If you have a mix of z9 and z10 processors with a common IEAOPT and you are using HIPERDISPATCH=YES with CPUVARY=YES for IRD, this affects you. The two parameters are mutually exclusive but accepted with no obvious error except that the CPUVARY by IRD will be disabled on z9 processors. At IPL time, HIPERDISPATCH=YES disables CPUVARY but then when it can't use HIPERDISPATCH on a z9 does not turn it back on. When I have an APAR number I will post it. In the meantime, to fix it, a separate OPT for the z9 systems with HIPERDISPATCH=NO will solve the problem either at IPL time or by using the SETOPT command.
