Sun Cluster Disaster Recovery | HP Legato Networker manual

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.
