Preliminary settings are necessary before installing RMS in the cluster system. Some of the procedures require you to modify system files so that RMS can identify the hosts, file systems, and network interfaces used in a configuration. You should have completed these procedures when RMS was installed.
In some cases, you will be creating or modifying your RMS configuration because changes have been made to your site. Certain site changes may require you to review and update your system files first. These changes include, but are not limited to, the following:
IP addresses were changed.
Redundant interconnects were added to the cluster.
Hosts were added, removed, or renamed.
Two or more clusters were merged into one.
File systems or SANs were added or removed.
The following sections describe how to preliminarily set up the configurations related to nodes, file systems, and networks. If any of these specifications have changed since your initial RMS installation, you should review this material and make the necessary adjustments before proceeding with your RMS configuration.
The modifications generally involve adding RMS-specific entries to standard system files; pre-existing entries are not affected. Resources for market-specific applications may require similar customization.
