DAC activation question - 27.Mar.2012 3:18:42 AM

Hello,

I have 3 different active directory sites. Each has 1 MBX server.

Two of the MBX servers seed over a single DAG to the thrid site (DR)

I've enabled DAC on the DAG, however whenever there is a network blip, the databases at DR activate.

I though DAC required a manual failover and wasn't automatic. Is this correct?

Just need clarification on this one.

Thanks

Graham

From what i understand DAC is automatic but it stops a server mounting a database until it can communicate with an active server.

Did you run the Suspend-MailboxDatabaseCopy mbx01\exmb01 –ActivationOnly on each server?

Yes, I've run Suspend-MailboxDatabaseCopy mbx01\exmb01 –ActivationOnly
on each database to stop this.

But without running the command the database automatically mounts

I'm guessing this is normal behavior searching on the net.

I guess this one can be closed off
