Thanks. That makes sense and I hadn't thought of that. I don't see any
other connections. However, it appears to have properly fenced one of
the nodes last night and I don't believe I've changed anything in the
config. Maybe I did have another connection and something I did
cleared it without me realizing it. As long as it's working. :)
I'm still pretty "green" when it comes to clustering and SANS and
sincerely appreciate the quality responses and willingness to help on
this list.

I am using an APC Masterswitch Plus as my fencing device. I am

This used to work just fine. If I run `fence_apc -a 192.168.42.30
-l cluster -n 1:7 -o Reboot -p <my password>` from the command line,
fencing works as expected. The relevant lines from my cluster.conf
file are below. I will gladly provide more information as necessary.
Is it possible that you are already telnet'ed into the switch from a
terminal or somesuch when the fence attempt takes place? APC switches
allow only one login at a time. I should/will add a log comment that
mentions this as a possible reason.
If this is not the issue, well, we can keep digging...
