I didn't debug in the end, but got it working by disabling LANPLUS option in
Luci -> Fencing devices -> iDRAC, less secure but it's a private vlan

If you paste your cluster config, it's pretty easy to convert that to the
command line call. The attributes have matching command line switches (the
man page should cover them). As for Dell, I believe you need to add an
attribute to tell it what prompt string to look for (not 100% on that

If you can sort out the 'fence_ipmilan .... -o status' command that works,
we can help you fairly easily convert it to the cluster config version.
