No databases mounting while two servers switched off in a DAG with 3 server
Posted on 2012-09-08
I have 3 mbx servers. in that 2 are in office and another is in data center. All three are members of DAG. mbx1 and mbx2 are in office and mbx3 is in datacenter.
mbx2 server is failed due to hardware failure. But still mbx1 and mbx3 are working fine. But If I shutdown mbx3 server, all databases in mbx1 dismounts. Means out of three servers, if any 2 servers down means, the databases will not come up in third server. Is this the default behavior of exchange DAG and how to over come it?
