Having an issue with a Site Failure.
Site A (Primary): Exchange#1(with all roles), Exchange#2 (with all roles), Witness#1
Site B : Exchange#3(with all roles),Witness#2.
Site B had a failure and we lost connectivity. However it also took down Exchange at the primary site. It is related to the cluster losing quorom. I thought that Witness#1 would have enabled it to maintain Quorom.
I can see in DNS that the DAG01 entry points to the server in SiteB where i expected SiteA.
What could possibly cause us an issue in this design?
How do get SiteA working again (SiteB is still down)?
