Now, how would I detect *that*!

We recently updated the software with the latest Centos 6 software but now the cluster will not start. It keeps throwing errors during startup when attempting to unfence the disks. I have hard reset the fiber switch, and reset both hosts, but when I run fence_sanbox2, I am unable to either enable, disable or even get status of the switch ports.

But the fence_sanbox2 script will not. The fence_sanbox2 code has not changed, however python has been upgraded from 2.6.6-29 to 2.6.6-36. Has anyone else seen this? Know of a fix? Am I doing/not doing something stupid? I seem to recall running this command before during setup and it worked just fine then.
