Recovering an Entire Cluster

How to Recover a Single Node

To recover a single node:

2.Start the NetWorker client.

3.From an unaffected node in the cluster, use the virtual NetWorker server to restore the node's data and software from a recent backup.

4.From an unaffected node in the cluster, use the SMIT utility to synchronize the cluster topology and resources.

Recovering an Entire Cluster

This section describes how to perform a complete cluster recovery including reinstallation of the operating system on all nodes in the cluster.

Note: It is unlikely that all the nodes in a cluster would fail simultaneously; but if this does occur, follow this procedure.

How to Perform a Cluster-Wide Recovery

	•	“Task 1: Install the Software” on page 166
12	•	“Task 2: Restore the Cluster Database” on page 166
	•	“Task 3: Start the Cluster” on page 167
	•	“Task 4: Restore the Data” on page 167
