That means also groups that are no longer valid in the plex (and will never become active again) will still be listed (XCF group member state changes when permanent status recording is on are complicated enough in theory and in the books, but that design change might have also changed this further, without documentation update). From here on out you have to specify each group name individually to see all member(s). So that is not exactly easy to determine how much rubbish might have accumulated. > > For comparison, take a dump of XCFAS and all its dataspace and then issue the ipcs couple sysplex detail and couple group detail commands to see what *that* might tell you (and where it differs from the displayed information). > > The way I determined that there were residual systems in the sysplex CDS (which was inactive at the time, so no display commands possible) was to simply *review* browse (from the cbttape) the sysplex CDS.

Barbara, I already did some research . I used IDCAMS PRINT to check the contents of the CDSs and found only valid systemids. Checking back what we did when, I concluded that we could not have polution in the CDSs. We converted our 'testsysplex' to a fully isolated sysplex, but this meant only full dasd isolation. The new testsysplex is polution free, so is the prodsysplex and the old testsysplex has been removed. Furthermore all this happened under z/OS 1.8, so I can't help you. The only thing I can do for you is check D XCF,S,ALL when one of the systems has been brought down, but I suppose you have a testplex yourself?
