You should be able to vary if off from VM with VARY Online|OFFline PROCessor nn
I don't remember exactly, but I think that there is a way to mark the CPU 'reserved' so that it doesn't come online after an IPL.

Sent: Tuesday, March 24, 2015 9:56 AM To: [email protected] Subject: Dynamically varying a CPU offline in ZVM Hi, Could one of the wise old wizards tell me if there is a CP command we can use to deactivate or vary a CPU offline at the hypervisor level? Young wizards appreciated too. We want to change the number of CPU's and understand the correct place to do it is in the HMC. But if we can do it dynamically initially, with the option of dynamically turning it back on, that's a less disruptive way than a IPL while we try this on for size. Thanks for the help!
