>It does work, I even tested it to make sure. They key is the HLQ of SYS1. I said that in my post but I should have explained why. That's what happens >when you start rambling. There is special code in DFSMS to allow SYS1 (and PAGE) to be cataloged in multiple catalogs. >OMVS HLQ... that is the recatalog issue. Change to SYS1.OMVS and it will work. Thanks, didn't realize that it was true for SYS1 as well. We also have FDR and realize I can do a straight copy, but don't want to rely on a process that requires that product, as DFDSS doesn't support direct copies of hfs/zfs last I knew. We are migrating away from FDR usage anyway. >I do it all in one jobstream. A job similar to what I currently do is on my web site in the JOBS/DOC section (CLONERES). Since I volume copy my primary >sysres with FDR, I don't have to worry about IPLTEXT. >I only rebuild it on the maintenance sysres when a PTF requires it. >As far as mod 27, we were just talking about it for 1.8 but it is too big of a waste. I'm only using slightly over a mod-9 (I just had to go to a second >mod-9 sysres for HFS when I installed XML toolkit under z/OS 1.6). Under 1.8 I have a few extra HFSes - PLI, COBOL, Netview - in addition to the ones I >had for 1.6 (ROOT, TSM, and XML). The only way I would consider mod-27 is if we also put our ISV sysres on it (we roll out ISV maintenance / software as >part of the sysres set). But I really don't want to put them on the same volume because sometimes we clone the IBM sysres or ISV sysres from a running >version instead of the maintenance version. The only reason why I rebuild IPL text EVERY time is to not miss any updated or changes made to IPL text introduced by maintenance(granted, not very often), but now I never have to think about it. DFDSS copies it too. My running sysres's are 50% utilized(saves room for those ever increasing ZFS dataset sizes). That includes TARGETzone SMPE environment that that sysres, DSSDUMP copies of ZFS, and the ZFS's themselves, which incidentally, make up 113,000 tracks out of the 491,000 available by themselves.
