When I hear "BIOS update" and Dell then some red alarm signs appear in 
front of my mind ...

Okay, what I want to say is: did they also check the NIC firmware 
version? We here had really big trouble with the Broadcom NICs in our 
R610 machines.

Probably that has nothing to do with your problem but that has also been 
our impression while analyzing the strange problems we've seen here.

Coming back to your error messages ... the rgmanager cannot get the 
status for your service? Which kind of service are you trying to setup? 
It sounds like it has run before? Could you manually start the service 
agent(s) on node2 and see what that gives you?

Another thing: did you already activate debug inside cluster.conf?

Kind regards,
