Although this is not an HMC task I find I can either add or take away a CP on an individual LPAR with the following MVS command.
CF CPU(1),OFFLINE <==== Puts one CP offline in this case CP #1 CF CPU(2),ONLINE <==== Puts one CP online in this case CP #2 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Jon Butler Sent: Thursday, May 12, 2016 10:34 AM To: [email protected] Subject: Re: Dynamic CPU ADD to a z/OS lpar You can add CPs or memory to an active LPAR, but you can't take either away without stopping the LPAR. You don't want more CPs assigned than you (or PR/SM) can use...it's just overhead. In fact, unused CPs will be "parked" on newer CECs when underutilized. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
