Fence_drac and fence_drac5 will not fence my cluster node with an iDRAC6.

Solution Verified - Updated -


  • Getting error "unable to login" using fence_drac.
  • Currently fencing with fencing_drac5 it will send init0 to the system.. not powercycling
  • When trying to fence my node with iDRAC6 fencing, we repeatedly see fencing fail:
    fenced[6326]: fencing node "rhel5clu3.example.net"
    fenced[6326]: fence "rhel5clu3.example.net" failed
    fenced[6326]: fencing node "rhel5clu3.example.net"
    fenced[6326]: fence "rhel5clu3.example.net" failed


  • Red Hat Enterprise Linux 5.4+ Advanced Platform (Clustering) or High Availability Add-on
  • Red Hat Enterprise Linux Server 6 with the High Availability Add on
  • iDrac6 fw: 1.03.10, all firmware version of iDRAC are probably affected by this issue.
