I think the focus here should be why it is rebooting vs disabling functionality. Do we know what the specific failure is ?

As mentioned below “The only time maintenance will power off a host outside of explicit administrative action is if that host’s board management controller is provisioned, the critical action for a sensor group has been changed to power cycle AND a sensor in that sensor group reports a debounced critical severity.” You would see customer logs to this effect.

Dear all, Will the fault management to do actions (reboot or shutdown) based on BMC's sensor status ? Thanks Qian, Bin <Bin.Qian@windriver.com<mailto:Bin.Qian@windriver.com>> 於 2019年6月25日 週二 上午2:23寫道: SM only requires mtce to reboot a failed controller during a failover, i.e, in a duplex environment, the survivor controller requires mtce to reboot the failed controller. SM won't require reboot when there is only 1 controller available (e.g an aio simplex).

Yes, SM can request mtce to reboot a controller and there will be an explicit mtce log for that (below) controller-? is being force failed by SM
