I have a server in my Exchange 2010 environment that is the passover node to my DAG. I have 3 nodes. Two of the nodes (one is the active and one is the passive) contain duplicate database copies. My passive node has gone down and the cluster service has disappeared on that machine. From what I'm gathering, the best way to get the cluster service back on that machine is to evict the node and re-add it. What I need to know is how is the best way to do that? Through Failover manager, or through the EMC GUI under Organization/Mailbox/Database Availability Groups. Any help would be greatly appreciated. Thanks!
