Method for automatically replying firmware of baseboard management controller

Abstract

A method for automatically replying firmware of a substrate management controller is suitable for replying the firmware of the substrate management controller, is implemented by a control unit electrically connected with the substrate management controller, and comprises the following steps: (A) starting timing; (B) judging whether a state message from the baseboard management controller is received or not; (C) when the state message is received, resetting the timing result, and returning to the step (A); (D) when the state message is not received, judging whether the timing result is greater than a preset time period or not; (E) when the time period is longer than the preset time period, updating a boot loader in the baseboard management controller to a target boot loader, and restarting the baseboard management controller; and (F) transmitting an abnormal notification to the substrate management controller, so that the substrate management controller updates the original firmware into the target firmware.

Description

technical field [0001] The present invention relates to a firmware updating method, in particular to a method for automatically restoring the firmware of the BMC applied to the BMC. Background technique [0002] Baseboard management controller (BMC, Baseboard management controller) is a controller used to monitor the status of an electronic device (eg: server). The baseboard management controller can provide an intelligent platform management interface (IPMI, Intelligent Platform Management Interface) to monitor, control and report the status of the server, and the administrator can perform remote management functions through the IPMI. However, when the BMC is abnormal and cannot be controlled through the IPMI, an engineer must manually restore the firmware of the BMC. Existing firmware restoration methods include the following three methods. [0003] The first method must be able to work under the condition that the BIOS of the server can still be turned on normally, and t...

Problems solved by technology

[0004] However, the methods for restoring the firmware of the baseboard management controller mentioned above must be restored by the administrator, and if the BIOS of the server fails to boot normally, the administrator cannot restore the firmware of the baseboard management controller remotely. , it is inconvenient to connect the baseboard management controller to the site to perform recovery operations
