I am using Exchange 2010 SP2 on all my exchange 2010 servers. I have 2 mailbox servers in primary site and 1 mailbox server in DR site.
When I tried to simulate actual DR, I am facing issues in activating mailboxes in DR site.
DAC mode is enabled.
To begin with, I shutdown the mailbox servers in primary site. I ran the stop-databaseavailabilitygroup command to mark the servers in primary site as stopped.
I also ran the same command in DR site also.
Then I stopped the cluster service in DR mailbox server.
I had already configured the alternate file share witness server long back.
Then I ran resume-databaseavailabilitygroup command in dr site. While running this command certain errors where shown as cannot evict mailbox servers in primary site.
If I go to failover cluster manager, dag is up with ip address of dr site.
However, my mailbox databases do not get mounted.
Require your help to resolve this issue.
