[Linux-cluster] Is there a fencing agent I can use for iscsi ?(GFS and iSCSI)

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.

Another option is fencing via power device fe. fence_apc, fence_apc_snmp
but You would need tu but APC hardware. Fenceing via fence_ilo,
fence_rsa. fence_ipmilan is the option if You would have IBM, Dell or HP
servers. You could also try fence_scsi without any costs, but it doesn't
works if You had multipath configuration.
