From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12 Description of problem: Fencing a 24 port APC switch fails. 16 ports works. The reason that failure occurs is that an unknown screen is encountered. When using a 24 port APC switch, it will request the user to hit enter to continue the scrolling of the port lists. The "enter" causing the script to fail. In a 16 port fence device, this "enter" is not required and the reason that it works. The "enter" for complete list needs to be added to the fence_script.
