How to: Recover from Failover Cluster Failure in Scenario 1
In this scenario, failure is caused by hardware failure in Node 1 of a two-node cluster. This hardware failure could be caused, for example, by the failure of a disk controller or the operating system.
To recover from a failover cluster hardware failure
After Node 1 fails, the SQL Server failover cluster fails over to Node 2.
Evict Node 1 from Microsoft Cluster Service (MSCS). To evict a node from MSCS, from Node 2, open Cluster Administrator, right-click the node you want to remove, and then click Evict Node.
Verify that Node 1 has been evicted from the cluster definition.
Install new hardware to replace the failed hardware in Node 1.
Using the Cluster Administrator, configure Microsoft Cluster Server (MSCS) to add Node 1 to the existing cluster. For more information, see Before Installing Failover Clustering.
Ensure that the administrator accounts are the same on all cluster nodes. For more information, see How to: Create a New SQL Server Failover Cluster (Setup).
Run SQL Server Setup to add Node 1 to the failover cluster. For more information, see How to: Add or Remove Nodes in a SQL Server Failover Cluster (Setup).
