Availability Replicas Role State
Some availability replicas do not have a healthy role.
This policy rolls up the connection state of all availability replicas and checks if there are any availability replicas that are not in a healthy role. The policy is in an unhealthy state when any availability replica is neither primary nor secondary. The policy is otherwise in a healthy state.
For this release of SQL Server 2016, information about possible causes and solutions is located at Some availability replicas do not have a healthy role on the TechNet Wiki.
In this availability group, at least one availability replica does not currently have the primary or secondary role.
Use the availability replica policy state to find the availability replica whose role is not primary or secondary, and then resolve the issue at the availability replica.
