Ok, if I understood well I need to have two primitives (or clones if I 
want) one for each device. Of course I need to run the stonith device of 
nodeA in nodeB, is this true ?

And, I am not sure about this kind of stonith because: we need a normal 
interface (better if is redunded as  a bonding for example) to access to 
iLO server interfaces but in each server there is only one iLO device. 
If you have two switchs to achieve high availability, you will need two 
devices... Other option could be two switchs, one for each ethernet card 
on each server (two cards by server) and then one iLO device to one 
switch and one to another switch. What do you think about this solution 
? Could be reliable ?

I have tested today with another server without iLO Advanced license and 
I can shutdown the server. The license only is needed to have a remote 
console that is like a remote kvm. It is very good but it isn't needed 
in Linux HA.
