RE: [Linux-cluster] RHSCv4 2-node cluster hangs while startingfenced



Hi Hirantha,

The fence device for nodeN has to be the ILO device that is used to
fence nodeN - i.e. the ILO device inside nodeN.

For the cluster.conf this means:
(...)
<clusternode name="nodeN" votes="1">
	<fence>
 		<method name="1">
 			<device name="HPiLO_nodeN"/>
 		</method>
 	</fence>
</clusternode>
(...)
<fencedevices>
	<fencedevice agent="fence_ilo" hostname="hostname of ILO device inside nodeN"
        login="ilouser" name="HPiLO_nodeN" passwd="ilopassword"/>
</fencedevices>

and so on...

I hope that helps,

Mark
