Modifying the Cluster Configuration

It may be necessary at some point to modify the cluster configuration. For example, it may be necessary to correct heartbeat channel or quorum partition entries in the cluster database, a copy of which is located in the /etc/cluster.conf file.

Use the cluconfig and cluadmin utility to modify the cluster configuration. Do not modify the cluster.conf file manually. To modify the cluster configuration, stop the cluster software on one cluster system, as described in the Section called Starting and Stopping the Cluster Software.

Then, invoke the cluconfig utility, and specify the correct information at the prompts. After running the utility, restart the cluster software.
