My understanding of the desired effect is that luci creates and shows one entry onscreen for each on and off pair of entries in cluster.conf. It appears that it is not consistently creating the pair and it is definitely displaying them wrong. Each on and off is shown as a redundant entry with no indication of "On" or "Off". Which is why I was confused about whether or not the pair was needed. I'm still not sure 'why' the pair is needed, it's an implementation detail of fencing. Do some fencing devices have different commands for turning back on? Or does it just allow the ability to configure "auto fence off, but only manual fence on" by deleting the on items. If this is the case then it seems that there should be a check box in luci to that effect. Perhaps the parsing code in luci (or wherever it's being parsed) is confused by the ordering: <device name="RackPDU1" option="off" port="3"/> <device name="RackPDU2" option="off" port="3"/> <device name="RackPDU1" option="on" port="3"/> <device name="RackPDU2" option="on" port="3"/> Since I manually fixed cluster.conf, luci now displays four entires for both nodes. I just reordered the entries in cluster.conf like this: <device name="RackPDU1" option="off" port="3"/> <device name="RackPDU1" option="on" port="3"/> <device name="RackPDU2" option="off" port="3"/> <device name="RackPDU2" option="on" port="3"/> to group them in on off pairs and now luci displays just the two. :) thanks scottb Ryan McCabe wrote: <blockquote cite="mid:20071113172210.GB12937@redhat.com" type="cite"> <pre wrap="">On Tue, Nov 13, 2007 at 07:55:56AM -0800, Scott Becker wrote: </pre> <blockquote type="cite"> <pre wrap="">I just updated to RHEL 5.1.

Because there are dual power supplies, both need to be turned off before either is turned back on to ensure the machine powers off. After both are off, both can be turned back on. The front-end hides this detail from the user. Did you enter identical fence configurations (except for the port numbers) in conga for nodes 2 and 3? If so, then they both ought to look like node 3's configuration, and you've hit a bug; node 2 will be fenced correctly, but it won't be brought back up.
