      I'm trying to get fence_drac5 working on a cluster
        I'm setting up of two Dell R410's.  The primary issue I'm seeing
        are timeouts.  The fence does seem to work as the other node
        will get shut down, but the script always exits 1.
        
          
    Please which version do you use? 

    
    This looks very likely to be bug resolved in
https://git.fedorahosted.org/cgit/fence-agents.git/commit/?id=4bd62484e17cc63b27a103c744ec11fb00610b48

    when autodetect of EOL was not working properly on DRAC devices when
    using ssh.

    
    m,

    
        Here's the output:

        Even though I pass "-o reboot", it still powers off.  It
          does the same even if I don't pass that option.
        

        I added --power-timeout 30 in the latest test to see if
          that'd help but no dice.  Doesn't work without it either.
        

        I have tried fence_ipmilan & it works great, but the
          iDRAC interfaces are somewhat exposed & need to use SSH
          for security reasons, which limits me to fence_drac5.
        

        Thanks.
