Recovering a Single Cluster Node

This section describes how to recover a cluster server on one node. This scenario assumes that the operating system on the participating nodes has failed and must be reinstalled. The functionality of the MC/ServiceGuard component on the node is also in question.

How to Recover a Single Cluster Node

To recover a single node:

1.Install the operating system and the cluster software. Configure the volume groups.

2.Add the node to the cluster:

a.Click Cluster in the System Administration Manager (SAM).

b.Select High Availability Clusters>Cluster Administration>Specify Nodes to Join Cluster.

Note: You can also use the cmrunnode command instead of SAM.

3. Recover the node’s data from a recent backup.
