Chapter 8: Sun Cluster Disaster Recovery
This chapter explains how to recover one or more computers in a Sun Cluster
3.x environment.
This chapter includes the following sections:
• “Prerequisites” on page 135
• “Restoring a Single Cluster Node” on page 135
• “Restoring an Entire Cluster” on page 136
Prerequisites
To help prepare for a disaster, complete the Sun Installation and Planning
Configuration worksheets. These worksheets contain information that you can
use to restore a cluster to its original configuration. These worksheets are
located in the Sun Cluster 3.0 Release Notes.
Additionally, ensure that you regularly back up both physical and virtual
NetWorker clients. A physical NetWorker client backs up a physical node. A
virtual NetWorker client backs up a highly available Sun Cluster resource
application. Examples of applications that can be set up as highly available
Sun Cluster resources include a NetWorker server or a web server application.
Restoring a Single Cluster Node
This section describes how to restore a single cluster node. This scenario
assumes that the operating system on the damaged node must be reinstalled.
