Description (partial)

I/O fencing related information to be incorporated in I&A guide.

I/O fencing is a mechanism to prevent uncoordinated access to the shared storage. It also works in the case of faulty cluster communications causing a split-brain condition.
I/O fencing is used to remove the risk associated with split brain. I/O fencing allows write access for members of the active cluster and blocks access to storage from non-members (even a node that is alive is unable to cause damage).
