I was testing fence_ipmilan on RHEL 7 cluster and noticed that running the fence agent with the option to power off the remote node, it appears to cleanly stop the remote node instead of removing power immediately. I suspect something like ACPI intercepting the power off and trying to stop RHEL 7 nicely. I read through the documentation and did not see any mentions of turning off acpid in RHEL 7 (may because it does not exist) like in the RHEL 6 documentation.
Is the proper way to disable acpi like functionality to use the kernel line acpi=off? Curious on what others are using with HP iLO.
Example of remote node’s /var/log/messages … the RHCS_TESTING lines are my unit testing scripts that insert the command I am running. You can see where I attempt to power off the node and then how system is starting to cleanly stop the node along with pacemaker.
