We've been running some beefy Debian servers, but of course one of them was not beefy enough, and we were asked if we could increase the number of CPUs from 32 to 48. Easy, I thought, until I rebooted the beefier server only to discover it had restricted itself to 32 CPUs, even though it knew 48 were present:
cpu: 48 configured CPUs, 0 standby CPUs Brought up 32 CPUs The output from uname is: uname -a Linux linux02 3.16.0-4-s390x #1 SMP Debian 3.16.7-ckt9-3 (2015-04-23) s390x GNU/Linux And it is running on a z/VM 6.3 host. I've searched through many documents and publications, but haven't been able to find anything that might help resolve this situation. Can anyone provide some insight, please?
