In Scenario 2, failure is caused by Node 1 being down or offline but not irretrievably broken. This could be caused by an operating system failure or a hardware failure.
Procedure
To recover from a failover cluster failure
-
After Node 1 fails, the SQL Server failover cluster fails over to Node 2.
-
Resolve the problem with Node 1.
-
Ensure that the Microsoft Cluster Service (MSCS) cluster is working and all nodes are online.
-
Attempt to fail over SQL Server to the recovered node. If this succeeds, no further action is required, with the exception of normal testing. If SQL Server fails to come online on the recovered node, see How to: View and Read SQL Server Setup Log Files.
