Hi All,
I have SQL Server 2016 (EE) with AlwaysOn configured in my environment. During a recent maintenance window I was updating IP Addresses/Names of resources in my WSFC and as a result the CNO was moved from under the Cluster Core Resources to being listed as a resource under AG Name as if it was the listener. This caused this one particular AG to then use the CNO as if it were the listener and made the AG failover to the Synchronous replica as the primary. Not sure how to get the CNO back listed under the Cluster Core Resources and removed from AG w/o breaking my WSFC along with the other AG's. CNO is circled in red below. Any help would be greatly appreciated![]()
