Thanks vfovermars,
That's pretty much what I'm using. I still don't see how to find the Test MDisk Group ID, but "0" seems to work for me (we only have one big pool on each SAN).
The problem now seems to be that the SAN is not creating a Flash Copy. It just sits at 0%, and the SRA waits and waits and waits.
I've started another thread - for up to date versions. You can see it here:
