Issue

Availability group is not ready for automatic failover.

Category

Critical

Facet

Availability group

 

Description

This policy checks to verify that the availability group has at least one secondary replica that is failover ready. The policy is in an unhealthy state when the failover mode of the primary replica is automatic, however none of the secondary replicas in the availability group are failover ready.

The policy is in a healthy state when at least one secondary replica is automatic failover ready.

 

Possible Causes

The availability group is not ready for automatic failover. The primary replica is configured for automatic failover; however, the secondary replica is not ready for automatic failover. The secondary replica that is configured for automatic failover might be unavailable or its data synchronization state is currently not SYNCHRONIZED.

 

Possible Solutions

Following are possible solutions for this issue:

  • Verify that at least one secondary replica is configured as automatic failover. If there is not a secondary replica configured as automatic failover, update the configuration of a secondary replica to be the automatic failover target with synchronous commit.
  • Use the policy to verify that the data is in a synchronization state and the automatic failover target is SYNCHRONIZED, and then resolve the issue at the availability replica.
