Problems solved by technology

[0005] This problem has always existed in the current field because when setting the server BMC system power-off recovery strategy, the impact on the server OS system shutdown was ignored, or no feasible solution was found to avoid it.

Abstract

The invention provides a BMC power failure recovery method and device. The BMC power failure recovery method comprises the steps that during BMC power failure recovery, a register of a BMC is updated;the value of the register of the BMC is read; and whether the BMC power failure recovery is system AC power-on operation or BMC reboot operation is judged based on the value of the register. According to the method, after judging whether the BMC power failure recovery is the system AC power-on operation or the BMC Reboot operation and determining that the BMC power failure recovery is the systemAC power-on operation, the state of a BMC system power failure recovery strategy is judged, and therefore the problem of OS startup during BMC system reboot is avoided. In other words, through the BMCpower failure recovery method and device, the problem that BMC reboot causes OS automatic startup in the power failure recovery strategy of a server system can be solved.

Description

technical field [0001] The present invention generally relates to the field of computer technology, and more specifically, relates to a BMC power-down recovery method and system. Background technique [0002] There are usually three power-off recovery strategies for the server (that is, a strategy for switching on and off the server OS system when the server power supply system is powered off and then restored), namely: Always On (the server is normally on), Always On Off (the server is always off), Last State (the state before the server is powered off). After the server system is deployed, sometimes users need to set the system power-off recovery strategy through the BMC WEB management interface. If the system power-off recovery policy is set to Always Off (the server is always off) or LastState (the state before the server is powered off), it will not affect the server's OS system. The server's OS system is used to run the client system software on the server. In other ...
