However, writing a fabric-type fence agent should be pretty straight forward. I assume the device has telnet or ssh access? Install the fence-agents package and then look for the 'fence_*' files. They will make for great examples to base a new agent on. The actual API is defined here; https://fedorahosted.org/cluster/wiki/FenceAgentAPI The main task is to ensure disconnection of the node. So after calling the switch, be sure to confirm that the port is logically disconnected before returning a success to the fenced caller. -- Digimer E-Mail: digimer@xxxxxxxxxxx Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?" -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
