Easy enough. Just flip the switch, turn off 'load on activate', and POR. Then activate your LPARS one at a time in priority order. When you run out of main, then that activation will fail. Reduce the allocation for that LPAR to fit.
The risk is that you will run out of main before you run out of LPAR's and you will have to deactivate and reduce several LPARs. If you do not 'load on activate', then you can back out before you IPL. Dynamic changes are oh so handy but oh so expensive. Well worth it IMHO but YMMV. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Ed Micucci Sent: Wednesday, May 10, 2006 7:47 AM To: IBM-MAIN@BAMA.UA.EDU Subject: HMC : Dynamic I/O We want to turn on the "Allow dynamic changes to the channel subsystem input/output (I/O) definition" switch on the HMC. But this will require storage, and I can not find reference as to how much. We currently have all available storage tied up among our LPARs. So I must steal some storage from an LPAR, and I'd like to keep it to the minimum. Any info will be greatly appreciated.
