We use Exchange 2013 CU3
Primary Site : 3 Mailbox Server + 3 CAS Server + 1 Primary Witness Server
DR Site: 2 Mailbox Server + 3 CAS Server + 1 Alternate Witness Server
When we shut down all three mailbox server in the Primary site. The database which are hosted in the 2 Mailbox Servers (i.e DR Site) are not getting mounted automatically.
All the DR databases resulted to dismounted state and primary server shown as service down. In Exchange 2013 we have concept automatic datacenter failover which has not happened. Any clue on it...
