FIX: You cannot select any replica when you fail over from an availability group that's in the resolving state

Symptoms

Assume that you create more than one availability group in Microsoft SQL Server 2014, and each node owned one AG group. When you shut down or power off one node suddenly, and you click failover on an availability group that's in the resolving state, in this situation, you cannot select any replica in grid, and the Current Primary Replica is wrong.

Cause

This issue occurs because the following statement returns the wrong primary replica for the resolving AG, it should be null. However, the following statement returns the active node:
select * from master.sys.dm_hadr_availability_group_states 

Resolution

The issue was fixed in the following cumulative update of SQL Server:
Recommendation: Install the latest cumulative update for SQL Server

Workaround

To work around this issue, use the following Transact-SQL command to fail over manually:
ALTER AVAILABILITY GROUP xxx FORCE_FAILOVER_ALLOW_DATA_LOSS;  

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
