Two types of programs are available for managing your Heartbeat cluster:
crm_mon provides an overview of the cluster
crm_resource views, modifies, and migrates resources (such as GroupWise agents)
crm_standby migrates all resources from a node, such as when maintenance is required
cibadmin lets you modify the configuration information in the cib.xml file
GUI HA Management Client (/usr/lib/heartbeat/haclient.py)
When you run this program, you are prompted to log in to the cluster as the hacluster user or you can be a member of the haclient group in order to log in. By default, the hacluster user does not have a password. You must give it one in order to run the HA Management Client.
