I'm building up a SQL Server AlwaysOn AG and I'm on the step "failover", manual and automatic:
I noticed that in the Windows Server Failover Cluster a "Current Host Server" exists. My knowledge says that this is the "master" of the cluster that the cluster hosts. But now I noticed that the "Owner Node", which hosts the Availability Group(-role) a other node could be. (The owner node is also the primary instance of the AG, right?)
Now for me there exist two questions for the normal operating of an AlwaysOn AG:
Q1: Should the "Current Host Server" the same as the Owner Node of the AlwaysOn AG?
Q2: Imagine if I want to maintain a host. Shall I first failover the AG (via SSMS or with ALTER AVAILABILITY GROUP...) to the second node/another node and at second a failover of the WSFC-Current Host?
Maybe someone could help me with this questions and give me some advice.
