Brian Sharing resources outside of the sysplex boundary using GRS-Star is pretty much a no-no.
There are some clever VM tricks that can be used to mount DASD volumes to other non-plex systems as read-only - however even this is going to fall foul when PDS-Es come into the mix. You might be able to overcome some restrictions using CA-MIM - however I doubt if even that can address the PDS-E issues (am not sure as have not used MIM for 10years or more).

We have 2 SMSPLEXES within a bronze SYSPLEX. GRS is common to all LPARS, but most everything else is not. Now we have a new DB2 application coming that will require application datasets which will be required to be written to from all LPARS in the PLEX. I've shared volumes before by having a storage group which is written to from one SMSPLEX being online and in read mode from another plex with no problems, but for both sides to be able to allocate, write & extend datasets then I'm wondering if there's any gottchas coming at me. We can create the same Storage Group on both SMSes and define all the same volumes within. Of course we need to have procedures in place to ensure that someone doesn't go adding or removing volumes to one side and not the other. We also need to make sure that HSM cant migrate datasets from these volumes because the other HSM wont be able to recall them. My only real concern, is will it all hang together if/when one of these dsns goes into extents on another candidate volume. Will this cause any problems to any LPAR thats not in the SMS that performed the extend?
