10.2.117.141 is not reachable - no ping, no ssh. I can only reach 10.2.117.140, which I see the the IMPI address. That explains the SMASH-CLP: it’s the RMM ssh interface.
So, given the fact that one of the nodes assigned to me is a Jump Host, I am not sure I can install FUEL on only the remaining two blades. I think FUEL requires three slave blades, plus the FUEL master, which I think would be the Jump Host
