Try fence_ipmi from the command line -- e.g.

fence_ipmi -a <ip> -o off -p <password> (etc.) - see what the output is.

There are two bugs which are fixed in CVS which you might be hitting: 

(1) fence_ipmi doesn't work with null passwords

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=218974

(2) fence_ipmi doesn't work with lan-plus components

(don't know the bugzilla # :( )

Also, fence_ipmi uses ipmitool.  If you get an "ipmitool not found"
warning, ensure that the OpenIPMI package from RHEL4 U3 or later is
installed.  The fence package does not require this any other packages
at install-time (Note: -not- a bug).
