RHEL 5.4 cluster with DRAC6

Dear List Members,

We are trying to create a two-node cluster
with RHEL 5.4 (AP). The hardware is two nos. DELL R610 servers. These servers
are having iDRAC6 and we are planning to do the fencing using these cards. The present
situation is as follows:

 We are able to fence the remote host by issuing the command
     fence_ipmilan for the IP address of the DRAC card of the remote host 
 The service is getting relocated if the host running the
     service is shutdown (init 0) or restarted (init 6). 
 But if we power cycle one node from the other node using the
     ipmitool command then the service is not getting relocated to the other
     machine. The clustat reports that the service is in "started"
     state in the node that has been power cycled though the status of the node
     is reported to be "Offline". The log file of the node that is
     not power cycled reports that it is failing to fence the other node.

     The IP addresses of the setup are as follows:

     Node : wmd01.tibs.edu.in

             IP address of the machine is
     10.100.4.11

             IP address of the DRAC is
     10.100.4.17

     Node : wmd02.tibs.edu.in

             IP address of the machine is
     10.100.4.12

             IP address of the DRAC is
     10.100.4.16

     The cluster.conf file is given below. 

<?xml version="1.0"?>

<cluster config_version="7"

<ip ref="10.100.4.13"/>

<script ref="wmd_http_script"/>

</service>

        </rm>

</cluster>

Kindly help us to resolve the issue
please. We are totally stuck up.

With regards,

Goutam
