> I was wondering if anyone has written a iscsi fencing agent that I could use. I saw one written in perl that ssh'd into the node and added an iptables entry in order to fence the server from the iscsi target. It was from 2004 and didn't run correctly on my machine.  Does anyone have any ideas? Or should I try and salvage the one I found and fix it up? Thanks.

if you need to use it (as suggested in that other reply), i'd make sure
it doesn't connect to a node but to the iSCSI target and adds the
firewall rules there :) or even better if you have a managed switch in
between where you can simply disable the ethernet port (or even better,
have iSCSI on a separate vlan and remove the port from that vlan) via an
ssh script or maybe snmp or whatever.
enjoy,
