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.
