Here is an example with passwords removed:

  <totem token="10000"/>
  <cman port="6809" expected_votes="1" two_node="1" broadcast="no"/>
  <logging syslog_facility="local3"/>

  <fencedevices>
    <fencedevice name="manual" agent="fence_manual"/>
    <fencedevice name="ilo" agent="fence_ipmilan"/>
    <fencedevice name="ilom" agent="fence_npm_ilom"/>
  </fencedevices>

  <clusternodes>
    <clusternode name="node1" votes="1" nodeid="1">
      <fence>
        <method name="method1">
          <device name="ilo" passwd="12345678" lanplus="1" method="cycle" login="user" ipaddr="10.39.170.233"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="node2" votes="1" nodeid="2">
      <fence>
        <method name="method2">
          <device name="ilo" passwd="12345678" lanplus="1" method="cycle" login="user" ipaddr="10.39.170.234"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>

</cluster>
