Sun Java System Instant Messaging 7.2 Administration Guide

Stopping, Starting, and Restarting Instant Messaging Components in a Deployment with Sun Cluster

The imadmin command checks to ensure it is not running on a cluster node before attempting to stop, start, or restart an Instant Messaging component. If imadmin determines that it is running on a cluster node, it returns an error instead of performing the command. Use the Sun Cluster administrative utilities to stop, start, and restart Instant Messaging components in a deployment with Sun Cluster.
