Check the IBMVM list archive for a note (and subsequent follow-up discussions) titled: "RELABEL SYSRES" was: Re: Backup RES Labeling Question" I posted it Fri, 4 Sep 2009 11:55:28 -0500
That post (which I really should re-write and re-post when I find a moment), and subsequent discussions pretty thoroughly explains how to safely relabel the sysres. The procedure works for 1st or 2nd level systems. Mike Walter Hewitt Associates The opinions expressed herein are mine alone, not my employer's. "C.

( as long as it doesn't crash your first-level, of course ). You have two approaches, really, if you have an LPAR environment available. Approach 1 is to create a UserID to be the second-level guest, LEVEL2VM, or whatever you like. Make copies of as many of your first-level volumes as you need to sufficiently present the "image" of your first-level. Define SPECIAL GRAF in your level 2 UserID so you can DIAL to it once you've gotten it IPL'd. Then, IPL it, and knock yourself out with whatever you want to try. Approach 2 is to do the same, but in a spare LPAR, if you have that luxury. The "Running Guest Operating Systems" manual in the z/VM doc set has some useful advice, too. Have fun!
