Thanks a lot for your information. It works for me. I tested on my Mt.Jade system with adding condition to bypass the policy when bmcRebootCause is xyz.openbmc_project.State.BMC.RebootCause.Watchdog } else if (bmcRebootCause == "xyz.openbmc_project.State.BMC.RebootCause.Watchdog") { info( "BMC was reset due to soft reset, no power restore policy will be run"); return 0; } > >> >> Thanks, >> >> Thang Q.
