Installation Overview

This chapter contains guidelines for two installation scenarios.

• Installing Solaris Resource Manager on an Existing Sun Cluster

• Installing Sun Cluster on an Existing Solaris Resource Manager Configuration

You can install Solaris Resource Manager and Sun Cluster in any order.

Both the Sun Cluster and Solaris Resource Manager products modify the /etc/system file during installation. Making changes to this file after a Sun Cluster installation can lead to unpredictable cluster behavior if the Sun Cluster modifications to this file cannot be accessed during boot.

The procedure to disable or troubleshoot Solaris Resource Manager instructs you to use the backup /etc/system.noshrload file in place of the /etc/system file. Be aware that if the system.noshrload file does not include the Sun Cluster modifications, this substitution can cause problems with your cluster.
