Thanks All. Here's what I've come up with. I'm going to allow everything to come up on D/R without intervention if it is a real disaster. If I am testing, I will allow it all to come up, and IP won't work, so I'll bring TCPIP and the linuxes down, and XAUTOLOG AUTOLOG2 Storage 6M. This way, if I'm in a test, programmatically I can q v storage from within autolog2 and make decisions based on that, one of which will be, if it's 6M: define timezone DR1 west 00.00.01 so that other apps can check for the existence of that timezone, and if they find it, we are in DR test.
