I have exchange 2010 server setup in "DAG" mode in my environment and I need to perform Disaster recovery test. My setup is as below. Please note that below setup issue apply the same for the same AD site Environment and and different AD site environment
- Two Exchange members in DAG group = SVR01 and SVR02 ( in DAG mode, SVR01 is Active, SVR02 is passive copy )
- Two server == SVR00 and SVR03 ( SVR03 is primary FSW server and SVR00 is alternate FSW server )
When I shutdown Active copy, email is still flowing as primary FSW server is up and running.
If I shutdown both FSW server and Active copy server, my passive copy DB will show as Disconnected and dismounted as well. I can't manually mount too. If I do I get error as attached.
My question is why it is not using Alternate file share witness server even though
I set Alternate file share witness server to use for DAG when Primary file share witness server down ? Both Exchange servers and FSW servers are in Exchange trusted sub system group.
What am I missing ? Could you please advise ?
Thanks in advance
