Fencing for GFS2/SAN was not discussed anywhere in the HornetQ User Guide. While Fencing is required by HornetQ, the variety of ways to enable Fencing precludes specific discussion in the User Guide. To fix the issue, a new "Fencing" section was added to the "High Availability and Fail-over" Chapter. The section describes how to locate more information about configuring Fencing in other Red Hat documentation.
