        Unfortunately using fence_ipmilan is not
          possible to display more debugging details, so as mentioned
          earlier could you please run ipmitool directly?
        
        
        ipmitool 
vv -I
          lanplus -H 
c-hv05.prd.sdis38.fr
          -p 623 -U stonith -P <PASSWORD> 
-L
          ADMINISTRATOR chassis power status
 
        
        
        Above should display more details ...
      
      
     
    root@hv04:/etc# ipmitool -vv -I lanplus -H c-hv05.prd.sdis38.fr -p 623 -U stonith -P 'xxx' -L ADMINISTRATOR chassis power status

If I understand that correctly, this is a request to open session to IPMI. If you haven't received any response, then I'd check:
1. Do you have IPMI enabled?
2. Is it exposed on the relevant IP/port?
3. Isn't there any firewall blocking access the client to the IPMI interface?
