Can somebody who's using the fence_sanbox2 agent let me take a peek at their config? here's what I have so far for fencedevices: <fencedevices> <fencedevice name="human" agent="fence_manual"/> <fencedevice name="san" agent="fence_sanbox2" ipaddr="fsm.cs.columbia.edu" login="foo" passwd="bar"/> </fencedevices> is the port indicated in the manpage the WWN for the host bus adaptor? -n port The port number to disable on the switch. here's what I think I should have in each clusternode entry: <clusternode name="blade01" nodeid="1" votes="1"> <multicast addr="224.0.0.1" interface="eth0"/> <fence> <method name="fibre"> <device name="san" port="2100000d55d32ced"/> </method> <method name="single"> <device name="human" port="128.59.18.1"/> </method> </fence> </clusternode> and to test this, I was going to suddenly turn off networking for the blade and see how the rest of the cluster reacts. -dan -- -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
