Hi

from your cluster.conf file


<?xml version="1.0"?>
               <clusternode name="node2.drctmb.com" nodeid="1" votes="1">
                 <clusternode name="node1.drctmb.com" nodeid="2" votes="1">
         <fencedevices>
                <fencedevice agent="fence_ilo" hostname="node1.drctmb.com"
login="root" name="NODE1" passwd="redhat123"/>
                <fencedevice agent="fence_ilo" hostname="node2.drctmb.com"
login="root" name="NODE2" passwd="redhat123"/>
        </fencedevices>

Your node name & fence device hostname is same.that should be different.

As you mentioned following command in working

fence_ilo -a "IP" -l "login" -p "Pass" -o status

replace hostname of fencedevice with ip you specify with -a option & check.
