That's possible (sharing of IPL volser) as long all those LPARS are on the same z/OS level. > My SMP/E points to an entirely separate target Mod 27 and set of OMVS > files.

Or are you sharing your catalogs? I believe it is safe to share a Read Only OMVS dataset, unless you have something to prevent sharing of such OMVS datasets, for example having a folder which is written to. Of course, moving from z/OS v1.13 to 2.1 requires two different IPL volsers during rolling upgrades.
