We have two Exchange 2013 servers (and a witness server) in a DAG. They are all VMWare virtual. We have recently migrated our 500 users from Ex2007 to Ex2013, so there is a bit of a learning curve for us. One of the servers "A" is has a better hardware situation than the other "B" server that is offsite. They both have the same memory and hard drive sizes. We would like to keep the databases active on the better A server. There was a situation with our primary A server the night before that caused the databases to be activated on the B server which in turn caused B to run all the resources up to 100% and be very. I was able to move the active databases back to A and put B in maintenance mode so that it won't fail over to B for right now until we can get B a better hardware situation.
Question is: Is it possible for B to keep getting the logs played to the server so that if there were a catastrophic failure on A, we could essentially activate the databases on B we would be fine. I don't want it to be activating on B on its own. I don't want to break the DAG because we want it to be able to eventually be used as designed, but it may be a month or two. Essentially, can we put the DAG in a manual mode?
Thanks.
