In my environment, what is the correct way to maintain my Exchange Servers - either scheduled reboots, power downs, patching, etc? Is there anything I need to do at all?
2 Exchange Servers - All roles installed on each
Both in DAG
Both in CAS Array with the IP pointing to DAG IP (No NLB but Automatic failover)
Exchange Server 1 is by all intents and purposes the "main" server. Exchange Server 2 is there for Mailbox or CAS failover.
If I were to do anything to Exchange Server 2, I'd think there isnt much I need to do except suspend the Exchange Server 1 Mailbox copy it is holding? Do I even need to do that?
If I were to do anything to Exchange Server 1, CAS Array should automatically route MAPI requests to Exchange Server 2, and DAG should as well right?
What happens when Exchange 1 comes back up? Any manual failback or all automatic?
