Recurring topic, for instance: http://clusterlabs.org/pipermail/users/2015-October/001567.html (scroll down under second item) As a corollary, you should make sure this scenario is indeed unlikely (e.g., because of NetworkManager activity).

Correct; for instance, see the description above the following table/anchor: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Cluster_Administration/ap-fence-device-param-CA.html#tb-software-fence-ipmi-CA + https://github.com/ClusterLabs/fence-agents/blob/v4.0.21/fence/agents/ipmilan/fence_ipmilan.py#L147 Similar to fence_ilo + fence_ilo2: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Cluster_Administration/ap-fence-device-param-CA.html#tb-software-fence-hpilo-CA + https://github.com/ClusterLabs/fence-agents/blob/v4.0.21/fence/agents/ilo/fence_ilo.py#L88 Also note that there can be sophistication on top of plain duplication; some default parameters can be internally adjusted as per how the agent is invoked: https://github.com/ClusterLabs/fence-agents/blob/v4.0.21/fence/agents/ipmilan/fence_ipmilan.py#L130 -- Jan (Poki)
