Recover One Failed NEC CLUSTERPRO/ExpressCluster SE Cluster Node

A cluster node that fails is automatically isolated from the cluster and all Cluster Groups active on the node are failed over to other healthy nodes.

To recover the failed cluster node

1. Shut down the failed node.
2. Disconnect shared disks from the node.
3. Follow the normal remote disaster recovery process to recover the node.

   Note: Restore only the local disk partitions during the disaster recovery.

4. Connect the shared disks to the node.
5. Reboot the node after restoration.
6. Perform the NEC ExpressCluster Server Return to Cluster operation, using one of the following methods:
   • Select a server name and select Control, Return to Cluster.
   • Right-click a server and select Return to Cluster from the pop-up menu.
   • Select a server and click the Return to Cluster icon on the toolbar.

   The Return to Cluster operation corrects inconsistencies in the configuration information of the cluster node where the fault occurred and returns it to normal cluster operation.
