Well, SBD can in principle fence any node, so yes, I'd say it is. In my
case (stonith:external/ipmi) it returns correct information. I am a bit
surprised that it also does it for non-existing node, but as far as I
understand if agent returns nothing host is not even checked and it is
assumed agent can fence anything.
