To support AlwaysOn Availability Groups, a server instance must reside on a node in the WSFC failover cluster that hosts the availability group, be AlwaysOn Availability Groups enabled, and possess a database mirroring endpoint.
Enable the AlwaysOn Availability Groups feature on every server instance that is to participate in one or more availability groups. A given server instance can host only a single availability replica for a given availability group.
Ensure that the server instance possesses a database mirroring endpoint.
