If a primary replica experiences an outage, the cluster is expected to fail over to one of the available secondary replicas. Instead, users will notice that the cluster keeps trying to start the failed primary replica. If that primary never comes online because of a permanent outage , the cluster never fails over to another available secondary replica. This issue affects all SQL Server versions, regardless of the cumulative update version that they are on.

Remove the start-failure-is-fatal override from the existing cluster. Decrease the cluster-recheck-interval value. Add the failure-timeout meta property to each AG resource.

If a replica goes down, the cluster tries to restart the replica at an interval that is bound by the failure-timeout value and the cluster-recheck-interval value. For example, if failure-timeout is set to 60 seconds and cluster-recheck-interval is set to seconds, the restart is tried at an interval that is greater than 60 seconds but less than seconds.

We recommend that you set failure-timeout to 60s and cluster-recheck-interval to a value that is greater than 60 seconds. We recommend that you do not set cluster-recheck-interval to a small value.
