[Linux-cluster] Cluster and Fencing on different subnetworks?



I have a RHEL6.3 cluster with RHCS and DRBD. When I kill the master node,  DRBD on the slave  calls rhcs_fence, but the script thinks its fails returning a (1) since the fence device was not on the same subnet as defined by the clusternode name in the  cluster.conf.  The fencing actually does occur, but when the fenced node reboots, and it tries fo come back in, the New master DRBD always reports Primary/Unknown.   THis requires a reboot of both nodes.

Is this by design or a problem. 

I switched back to Obliterate-peer.sh and the problem goes away. 
here is an excerpt from my cluster.conf.

I </clusternode>
		<clusternode name="cl_lm04.ionharris.com" nodeid="2">   ##10.10.10.x
			<fence>
				<method name="lm04_fence">
					<device name="lm04_ipmi"/>
				</method>
			</fence>
		</clusternode>
	</clusternodes>
	<cman expected_votes="1" transport="udpu" two_node="1"/>
	<fencedevices>
		<fencedevice agent="fence_ipmilan" ipaddr="192.168.155.119" login="root" name="lm03_ipmi" passwd="nvslab"/>
		<fencedevice agent="fence_ipmilan" ipaddr="192.168.155.100" login="root" name="lm04_ipmi" passwd="nvslab"/>
	</fencedevices>

Best regards
