Fence device options are actually recommended in the Red Hat Knowledgebase article 28603: "Fence Device and Agent Information for Red Hat Enterprise Linux"...
For iLO3 is says "fence_ipmilan needs to be used with the -P option to enable Lanplus. It also requires usage of the -T parameter to provide a 4 second timeout rather than the default fence_ipmilan default of 2 seconds. The -T parameter is provided in versions of fence_ipmilan from Red Hat Enterprise Linux 5.5.z and up."
