Most probably you don't have the 'meta provides="unfencing"' to your fencing device.
I dont have the configuration wrt fence_scsi right now, coz I started experimenting with something else. I will try this option, but I still dont know even if I configure this option what will trigger unfencing operation to this node ? I read at multiple places -- "The failed node will no longer be able to write to the device(s). A manual reboot is required."
Since reboot was not an option for me, I didnt configure that. But doesnt this sentence mean that a manual reboot needs to be triggered to the node, and during the course of reboot (maybe be before rebooting), the node shall be unfenced.

What I would want is to be able to "unfence" the node without rebooting. Is there a way to do it ? Can a node unfence itself once the issue with the node is resolved ?
