I have 4 exchange 2016(A, B, C, D), 2 in main site (A and B) and the other 2 in DR (C and D).
All DBs are mounted on B. I have 2 scenarios that occurred.
Please note that the preference of the DBs are B, A, C, D and nothing on the network happened to justify this behavior for both scenarios
When B was turned off,
the DBs got mounted on D and DAG IP was brought online in DR site.
the DBs got mounted on A which is correct but DAG IP was brought online in DR site.
Can someone help why this behavior is happening?
