I have contacted the manufacture of the UPS. There is no configuration on the UPS end. The UPS contains a relay card, which sends a signal to the Power8 server when running on battery power. The UPS will then send another signal to the Power8 server when the utility power has been restored at the UPS. That signal is making it to the openSUSE LPAR because I see this when the UPS goes on battery power:

When this occurs, openSUSE starts a shutdown. Instead of it running whatever script it is running to start the shutdown, I want to run the rc.powerfail script. Do you know of anyway for me to find out what script is running which causes openSUSE to shutdown when the above conditions crops up?
This message appears in the kernel: https://github.com/torvalds/linux/blob/master/arch/powerpc/platforms/pseries... The kernel shuts down immediately on receiving the MCE. Maybe raise the issue on the linuxppc-dev mailing list. Can't really comment on this design. Maybe there is some information in the event that would allow the kernel decide if it needs to shut down immediately and maybe the interface is broken and there is not enough information to tell how long the battery power can last and if immediate shutdown is required.
