Hi, I currently use a different method of fencing in our clusters (using iscsi ietd and iptables currently), however we have the APC7900 PDUs and do control them using SNMP: Use SNMP set commands to turn off and on the ports: snmpset -c <password> <host> PowerNet-MIB::rPDUOutletControlOutletCommand.<port> i 2 The 'i' refers to an integer and the digit 2 means to power off the port. That has worked very reliably.
