Marcy, Is that true?
You are running z/VM 5.4 on z10 and z196 now? The z196 was announced last June and shipped only this month and you already have it up and running?

Check that it IPLs, basically... not a lot we can do there. Then our vm test lpar. Make sure everything comes up. Maybe start a Linux there. Then our 2 Linux test/dev lpars, which run lots of servers. Gets a lot of exercise there. Let it cook a few weeks. Roll to the 6 production LPARs, starting usually with the 2 that don't run Linux. Then 2 Linux on a weekend and the other 2 on another weekend. We have the z196 maint with RSU 1002 on all of test dev now (3 lpars). On both a z196 and a z10. All is well, YMMV;) Marcy ________________________________ From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of George Henke/NYLIC Sent: Thursday, September 23, 2010 10:58 AM To: [email protected] Subject: Re: [IBMVM] Applying Maintenance - Best Practice I suppose RSU maintenance gets burned-in at Level 2, whereas COR maintenance goes right in to Level 1. But , what bout PSP COR? Level 1 or Level 2.

Do what you would normally do when applying maintenance... do you put it on 1st or 2nd level first? If your 2nd level system is meant to be a z/VM 'test' system, then it seems like you're already committed to that level of effort.

We currently have both environments for 5.4. I suppose the quickest and easiest (maybe dirtiest too?) way is just to put it on at Level 1 and fall back to CPOLD if there is a problem. "Best practice" may call for putting it on at Level 2 first, but the nature of the change may not warrant that level of effort. There are, however, 45 or more prereq fixes also going on with these 2 APARs, VM64879 VM64881. Just interested in what everyone thinks.

Also you want to check PSP on IBMLink and look for 2817DEVICE and see what recent stuff is needed for that system type (or whatever one you are installing). ________________________________ From: The IBM z/VM Operating System [mailto:[email protected] < mailto:[email protected]> ] On Behalf Of Bruce Hayden Sent: Wednesday, September 22, 2010 7:27 AM To: [email protected] <mailto:[email protected]> Subject: Re: [IBMVM] What is the z/VM 5.4 Compatibility PTF for z196?

We will probably take your advice. We will probably bring up the z196 with 5.4 first and then move 6.1 up to Level 1 afterwards. -- Bruce Hayden z/VM and Linux on System z ATS IBM, Endicott, NY <http://www.vm.ibm.com/service/vmreqze.html>
