Thanks your response for this topic.
This information is NOT used to check if BMC is rebooted or others.
Thus, the Host status will not be changed when BMC is rebooted.

Subject: Re: Check on BMC Reboot Cause

Thanks Tim for your response.
I have one more question on this topic. With BMC reboot cause supported, is=
 the information used to check if BMC is rebooted or powered ON to skip cha=
ssis policy (always-on, always-off, previous) when BMC is rebooted? The rea=
son is that the Host status should not be changed when BMC is rebooted.
