Ah, the constant rebranding and re-lingo-ing. It must really help sales. The last time I had IBM storage, Global Mirror was PPRC/XD and "z/OS Global Mirror" was GDPS/XRC. And Metro Mirror was PPRC synchronous. I can't see how GDPS/XRC would work with non-unique addresses--at least between primary and secondary, since they're both online to the SDMs (right? getting fuzzy on it). Currently we use HUR (love it), but I don't believe it would work with non-unique addresses either.

Exercise caution when clicking links or opening attachments.] We mirror with XRC, which I believe is Global Mirror. (I cannot keep the current lingo straight.) In my shop, we have a business need to put any device--DASD or tape--online to any LPAR regardless of location. In order to do that, device addresses *must* be unique. If you have absolutely no need to do that, then I don't think uniqueness is required. OTOH is costs little to make them unique. If you don't do it from the get-go, it will be very difficult in the future. . .
