Verifying that the Cluster Host is Restored

  • Article

Applies To: Windows Server 2008

Before placing the Network Load Balancing (NLB) cluster into a production environment, you need to verify cluster host restoration to ensure that you can properly restore a cluster host that has failed.

To verify the cluster host restoration process

  1. Remove a single host from the NLB cluster. Before removing a host from the NLB cluster, you should use the drainstop command to disable new traffic handling and stop NLB. While draining, a cluster host continues to complete any outstanding requests and remains in the cluster until all active requests are completed. At this stage, the cluster host stops all cluster operation. For detailed instructions on how to remove a host from an NLB cluster and using the drainstop command, see NLB product help.

  2. Remove all disk volumes and disk partitions on the cluster host.

  3. Restore the cluster host based on the installation method selected earlier in the deployment process.

  4. Restart the cluster host.

  5. Verify that the System event log of each cluster host contains no errors and that the restored cluster host responds properly to client requests.
