There have been some (mostly small) additions to the parameters you can set for some of the fence devices. These updates have been incorporated into the fence device tables, but this document also provides screenshots of the luci interface and these should probably be updated.
Of course, since the luci screens simply repeat the identical information (in the identical format) as appears in the fence device tables -- and in cases where there are parameters that are set at the node instance rather than when configuring a global device those instance screens are not in the document anyway -- we might consider simply not providing the luci screens.
But clarifying what is set where (intance vs. global) is probably a good idea.
At this point in the RHEL 6 lifecycle this does ot seem worth doing, so I'm closing this. If we get any actual customer feedback or bugs filed from somebody other than me I will open a new bug.
