Chapter 10: HP-UX Cluster Disaster Recovery

This chapter explains how to recover one or more computers in an HP-UX

MC/ServiceGuard cluster environment.

This chapter includes the following sections:

• “Recovering a Single Cluster Node”

• “Performing a Cluster-Wide Recovery” on page 154

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.
