iLO fencing works just fine. You might be missing perl-Crypt-SSLeay which is
for iLO fencing. You need to put all the fence_ilo options in the "fence.ccs"
option ' action = reboot (or off) for in the fence section of your nodes.ccs
RHEL3+GFS6.0x. If you are using RHEL4 + GFS 6.1, then it is simpler since the
is expected to be in the same file etc.
In either case, you need to make sure the web access to the iLO port is
working and that
you have a valid account in the iLO config (the built in Administrator
account will work)
Also, if you are using RHEL4 and an updated iLO firmware, you need to disable
management for the machine due to a change in the way the iLO powers off the
seems to try a nice shutdown by sending the machine into runlevel 6 instead
of just pulling
the carpet out from under it.
My suggestion to the fencing agent coders would be to issue a "power reset"
instead of a
"power off" as a reset will in fact pull the plug, and is much faster (and
than a power off command.
Also, you can always add more than one fencing method to each node. For
instace, you can
fence the machine at the fibre port as well. I believe you need to manually
enable the port
again once you have determined that there is no problem etc.
Any specific problem you are having?

Do you use iLO port for fencing?
Please can you explain your iLO configuration?
I have some doubts on how to configure fencing.
you have nodes A,B and iLO devices Ai, Bi Fencing device for node A should be
Ai or Bi?
I had also troubles on installation of additional perl modules required to
make fence_ilo agent work:
despite having IO::Socket::SSL and Net::SSL::something correctly installed,
it keeps throwing error messages and I can't seem to correctly startup
