[Linux-cluster] fence_apc 7930s

[Eric Schneider]

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?

 

OS - CentOS 5 2 node cluster

Fence Devices - 2 x apc 7930s
