Chapter 7: Microsoft Cluster Disaster Recovery (Windows NT 4.0)

Task 1: Evict Node_B from the Cluster

To evict Node_B from the cluster:

1. Ensure that the cluster resources failed over to Node_A, the working node.

This includes the quorum disk and any shared disks.

2. If any of the data that failed over from Node_B to Node_A is corrupt, use the NetWorker software to recover the data.

Note:

You may need to shut down some cluster resources that depend on this data.

3. From the Cluster Administrator on Node_A, evict Node_B from the cluster.

4. Shut down Node_B if it is still running and disconnect it from the cluster.

5. Fix or replace the damaged hardware on Node_B, if necessary.

6. Reconnect Node_B to the cluster.

Task 2: Reinstall Windows NT 4.0 and MSCS on Node_B

To reinstall Windows NT and MSCS on Node_B:

1. Reinstall the Windows NT 4.0 Server Enterprise Edition.

2. Apply Windows NT 4.0 service pack 3.

3. Reinstall the MSCS software.

4. If the node had a local tape drive, reinstall the device driver.

5. Reinstall the latest Windows NT 4.0 service pack.

6. Join Node_B to the cluster with Node_A.

7. Assign the same drive letters that were previously assigned to the disk volumes.

Important:

The assigned local drive letters must not conflict with the drive letters assigned to any of the shared disks.
