Task 1: Replace the Damaged Hardware
Replace the damaged equipment with the same or similar model equipment as installed previously. Connect all the equipment as previously connected.
Task 2: Verify Hardware Mappings
Open the SRM console on the node you are restoring (down node) and set the logical mappings for the node’s managed disks and volumes to their original settings. To help complete this step, use the information that was recorded from the SRM console prior to the disaster.
Task 3: Partition the Down Node’s Boot Drive
To partition the down node’s boot drive, you need the original node’s partition information. This information should have been recorded prior to the disaster.
Note: Perform this task from a working cluster node.
To partition the down node’s boot drive, use a utility such as diskconfig and specify the original partition settings.
Task 4: Update the Cluster Configuration
To update the cluster configuration, delete the cluster node and then add it back into the cluster. When you add the node back, cluster hardware settings are reinitialized.
Note: Perform this task from a working cluster node.
