If you're interested in the highest CPU number, SCCBNCPS has never been a valid indication.. As its comment says, it is an indication of how many CPUs are installed. There is no architected guarantee that CPU numbers are defined without "gaps". SCCPNCPS is just the number of CPU entries present in the SCPINFO. The entries themselves have to be examined to see the CPU number and then you would take the highest one that is found.. Regarding "does not get updated after IPL" you are presumably looking at the area mapped by CVTSCPIN. This area intentionally is not updated after IPL for compatibility reasons. Try the area pointed to by ECVTSCPIN. For what it's worth, SCCBHCPA is the highest CPU number that the machine thinks it can support.
