Andrew, We have a similar mixed environment. We approach it probably as Mark does. SYSPLEX(YES) on all systems that use the shared SYSPLEX ROOT on the small subset of shared DASD (with CDS' and a PARMLIB). We had one pre-existing sysplex that fully shares its DASD. The rest of the previously monoplex systems do not share with this sysplex or with each other (yet). We have one more sysplex merging in on 7/20. It works, and it's not complicated.
SYSPLEX(YES) only requires a common SYSPLEX ROOT within the Sysplex that all systems can get to. Multiple "HFSPlexes" is not allowed within a Sysplex, but there are no rules (that I have found) that state you cannot limit the degree of filesystem sharing you exploit, other than the ROOT. We did get caught by mountpoints and symbolic links for a couple of applications that were differrent on our monoplex systems. Once we reconciled the directory structure and BPXPRM mountpoints, we were fine. You may have to reconcile your automount policies, too. The "Merging Systems into a Sysplex" redbook, SG24-6818 is another fine reference for HFS and other components.
