Well, the place to begin is with the version of iLO your machines are 
currently running. Can you check this rev number and post here?

The conf file looks good. The fact that the CLI is working but the 
fence_node command is NOT would suggest that either one of the params in 
the conf file is incorrect (should Administrator be capitalized?) or 
that the param name itself is incorrect. The param names all look ok.

Please let us know the iLO firmware version, Olivier. This is troubling 
to me -- iLO is our most stable supported form of baseboard management 
fencing.
