To set up an Availability Group with two servers, the servers both participate in a Windows Failover Cluster.
I've seen cases after certain failover modes where the primary IP address in the cluster (in Windows Server Manager -> Failover Cluster Manager -> Cluster Core Resources) can be the address associated with the secondary replica in the AG.
Is this a problem – does it matter at all?
More generally, is there any reference on how the WFC relates to the AG, and to the Availability Group Listener?
