Hi, There's a fence_apc_snmp.py script available in the cluster code repository: http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/fence/agents/apc/?cvsroot=cluster I tested it a little (replaced /sbin/fence_apc with it - they both have the same CLI parameters) and it seems to work where the fence_apc script shipped with RHEL5 fails.
