Cluster services in RHEL 4.8

We have two of our Servers ruing on RHEL 4 Update 8, using Cluster suite to run common services. Currently due to some constraints we have no plans to upgrade the OS. But we have some maintenance activity on the servers, for which we need to stop and start the cluster services on both nodes.Kindly help to know which services to restart. In RHEL 5 and above we usually just restart "cman" and "rgmanager" which would take care of everything. But not sure for RHEL4.8. So kindly help. This is the cluster configuration that we have on the nodes:

<?xml version="1.0"?>
<cluster alias="Airguard_stc" config_version="1" name="Airguard_stc">
  <fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>

  </method>
  </fence>
  </clusteode>
 <clusteode name="eir2-c" votes="1" nodeid="2">
 <fence>
 <method name="1">
  <device name="eir2-ilo"/>
  </method>
  </fence>
  </clusteode>
  </clusteodes>

  </rm>
  </cluster>

Also Can you please give me any link for RHEL4.8 Cluster Suite Management ?
