Ok, so I have my global cluster setup, though it is really doing nothing right now. In the meantime, I'm looking at the SRDF agent information and it makes no sense.
It says:
- In a replicated data cluster environment, all hosts are part of the same cluster. You must connect them with dual dedicated networks that support LLT.
- In a global cluster environment, you must attach all hosts in a cluster to the same Symmetrix array.
I currently have a DMX at our primary site which is replicating some data using SRDF to another DMX at our DR site. I have a cluster at the primary site and a separate one at the DR site with the global cluster option turned on between the two. So, #1 makes no sense because if I'm using LLT, why would I be using global clustering? Wouldn't I just be using a regular cluster? Then, with #2, global clustering is based off of 2 clusters being joined between sites. How am I going to implement global clustering with a single cluster with everything attached to the same Symmetrix? Where is the DR with that? The Sym goes down and everything is gone.
