Exchange 2010 Database not mounting in DR Site

Dear Experts,

AD main Site:
2 x CAS/Hub Servers (with 1st server as file share witness)
2 x Mailbox Servers

AD DR Site:
1 x CAS Server (Alternate file share witness)
1 x Mailbox Server

i am in the process for testing failover to DC, i disconnected the link between DC and DR Site, i followed an article and all went fine.

my database is showing as dismounted, i gives me attached error when i try to mount it.

It seems that my active manager is server MB01 which is in DC and off.

i also ran shutdown cluster and started and took quorum properly but still database is not mounting.

Any help on how i can forcefully make DRC server as active manager when DC site is not accessible?

Dear MAS,

sorry for the late reply, the problem turned out to be that when i check dag properties in shell it showed that DR Site servers in stopped state.

So i stopped dag in my main site from DR Site and restore dag in the DR Site, after that i managed to mount the database.
