Task 1: Recover the System State and Quorum Data

To recover the system state and quorum data:

1.Select a node in the cluster that has the good (and possibly the latest) backup of the system state and the quorum data. (This procedure uses Node_A, for example.)

2.Verify that the Cluster Service is running on Node_A.

3.From Node_A, recover the following:

•System state

•Quorum data (If the quorum disk is owned by a virtual server, use the directed recover procedure. For details, refer to the Legato NetWorker Administrator’s Guide, Microsoft Windows Version.)

Make sure that you recover the quorum data to a different directory on the quorum drive.

For example, if the quorum data previously resided in G:\MSCS, recover the data to G:\RECOVER\MSCS.

4. Shut down Node_A.

Important: Do not reboot Node_A.

6 Task 2: Replace the Quorum Data with the Recovered Quorum Data

To replace the quorum data to Node_B:

1.On Node_B, uninstall the cluster software.

2.Reboot Node_B.
