I am having issues getting fence_apc to work in my environment.
I get the following error when I try to fence:
May 11 09:22:22 sleepy fence_node[4002]: agent "fence_apc" reports: failed:
unrecognised menu response
I remember dealing with this before (on RHEL 4) and I had to use a 3rd party
fence_apc to get this working.
Has anyone else had this problem? If so, how did you fix it?
