This still feels wrong to me.
All my newer dells have an enterprise idrac, but i have one PE2900 without it 
(shared port for OS and BMC), and it does work as on would expect

at this point I would probably recommend to get idrac enterprise cards, they 
seem to be available rather cheap on ebay.

as pointed out by Digimer, this might be a bug with older fence_ipmilan, 
causing the timeout parameter to be ignored

sorry, I have no experience with HP servers, but as stated above, this is not 
how it is supposed to work
