You don't _have_ to wait for evening. CP permits you to CPFMTXA spare DASD, and add them on the fly. Whole DASD volumes are recommended for page space. "Best practices" includes allocating page packs as: PERM 0 0 PAGE 1 END (Actually, it's safest to always reserve cylinder zero on all whole VM DASD as PERM space).
There have been many previous discussions on the listserve about how to dynamically add page volumes.

Is it a fair assumption that if I'm using 73% of the 3 page packs most of the real memory is 100% fully utilized? I have 512mb allocated to expanded storage. -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Marcy Cortes Sent: Tuesday, June 24, 2008 3:41 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization First, get that 73% number to < 50% ASAP.

So if I were to summarize this out of 8gb real storage assigned to the lpar performance toolkit is showing 89% usage. And from my 3 page volumes I'm using 73%. Sound right. ________________________________ From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Dave Yarris Sent: Tuesday, June 24, 2008 3:04 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Performance toolkit under zVM 5.3...Looking to see a snap shot of CPU utilization and Storage Utilization A lot to look at on the screens, but option #1 "CPU load and trans." and option #2 "Storage utilization" on the PERFSVM green screen should tell you most of what you need to know to give you some idea.

We are trying to determine if another IFL is needed or more real storage on the box.
