During maintenance it may necessary to start/stop resources on specific nodes. Linux HA manages the life cycle of resources and where they are deployed. Trying to start stop processes externally may cause conflicts. The state of the HA system is held in an internal XML file that is synchronized across all nodes. Staring/Stopping a resource is accomplished by editing the XML file with command tools included in the heartbeat package. Moving or stopping a resource can be done from the command line.
