fence_ipmilan leaves server powered-off despite 'stonith-action' property set to "reboot"

Issue

Although the cluster property stonith-action is set to reboot in our cluster, a node is left powered-off after being fenced by fence_ipmilan. The fencing method is set to onoff as opposed to cycle:

man fence_ipmilan:

       -m, --method=[method]
              Method to fence (onoff|cycle) (Default Value: onoff)
