Abstract

The present invention provides a method and a system for detecting startup states of a baseboard management controller (BMC) of a server cabinet. The method controls a remote management console (RMC) of the server cabinet to send a command to the BMC, where the command controls the BMC sends a response value to the RMC while the BMC starts. The method further determines whether the RMC receives the response value in a determined time interval. When the RMC does not receive the response value in the determined time interval, the method determines that the BMC fails to start. When the RMC receives the response value in the determined time interval, the method further determines whether the response value is a predefined value. When the response value is the predefined value, the method determines that the BMC starts normally. When the response value is not the predefined value, the method determines that the BMC starts abnormally.

Description

Baseboard management controller startup state detection method and system

The present invention relates to a substrate management controller detection method and system, and more particularly to a method and system for detecting a startup state of a substrate management controller.

When the server cabinet (for example, the rack cabinet) is powered on, the board fails to report the board in time. If the board management controller (BMC) of the board fails to start. Abnormal, and the BIOS (Basic Input Output System) will not take any action. At this point, maintenance personnel are needed to understand the problems with BMC initialization. Today's server architecture uses the overall power supply and fan wall to adjust the temperature of the server cabinet. The power consumption and temperature are collected by the Remote Management Console (RMC) after the BMC starts normally. When the BMC lacks the necessary monitoring means during the startup process, the BMC will have a serious impact on the stability and security of the server cabinet when it is down during the startup process.

In view of the above, it is necessary to provide a substrate management controller startup state detection method and system, which can realize timely detection of the BMC startup state through the remote management console.

A substrate management controller startup state detecting method is applied to a server cabinet, the method comprising the steps of: (a) controlling a remote management console to send its own state detection command to a baseboard management controller BMC, the self state detection instruction being used for Controlling the BMC to return a response value to the remote management console during startup; (b) determining whether the remote management console receives the response value within a preset time; (c) when the remote management console is When the response value is received within the preset time, it is determined whether the response value is a preset value; (d) when the response value is the preset value, determining that the BMC is a normal start; (e) when When the response value is not the preset value, it is determined that the BMC is abnormally started; and (f) when the remote management console does not receive the response value within the preset time, it is determined that the BMC fails to start.

A baseboard management controller startup state detection system running in a server cabinet, the system comprising: a control module, configured to control the remote management console to send its own state detection command to the baseboard management controller BMC, the self state detection instruction The control module returns a response value to the remote management console during the startup process; the determining module is configured to determine whether the remote management console receives the response value within a preset time; the determining module is further When the remote management console receives the response value within the preset time, determining whether the response value is a preset value; and the state determining module is configured to: when the response value is the preset The value determining module is further configured to determine that the BMC is abnormally activated when the response value is not the preset value; and the state determining module is further used. When the remote management console does not receive the response value within the preset time, it is determined that the BMC fails to start.

Each motherboard 30 includes a Baseboard Management Controller (BMC) 31 for monitoring power consumption and temperature of the server cabinet 100. The BMC 31 and the remote management console 20 are connected through an Intelligent Platform Management Interface (IPMI) or an Inter-Integrated Circuit (I2C) bus. The remote management console 20 is configured to send a Get Self Test Result command to the motherboard 30 to cause the BMC 31 to return a response value during the startup process. At this time, the startup status of the BMC31 is different. The response value generated by the BMC31 is different. For example, when the BMC31 is normally started, the response value is a preset value (for example, 55h). When the BMC31 is abnormally started, the response value is not. The value of the preset value (for example, 57h or 58h), when the BMC31 fails to start, there is no response value.

The remote management console 20 includes a flash memory 21 for storing a system event log (SEL) generated by the BMC 31 when a startup failure or an abnormal startup occurs. The SEL is used to record the error information of the BMC31 when it is abnormally started and failed to start. The error information includes time, cause of error, and the like. The storage device 40 is configured to store a correspondence between the return value and the error type of the BMC 31 during abnormal startup. For example, when the return value is 57h, the error type is that no data or device is available, and when the return value is 58h, The error type is a hardware fatal error that needs to be replaced or fixed.

The state determining module 13 is further configured to determine that the BMC 31 is abnormally started when the response value is not the preset value, and determine the BMC 31 according to the correspondence between the return value stored in the storage device 40 and the error type. The error type is stored in the flash memory 21 of the remote management console 20 by the error type and the SEL generated by the BMC 31.

The state determination module 13 is further configured to: when the remote management console 20 does not receive the response value within the preset time, determine that the BMC 31 fails to start, and store the SEL generated by the BMC 31 to the remote management console. 20 flash memory 21 in.

The prompt module 14 is configured to control the server cabinet 100 to display prompt information to prompt the startup state of the BMC 31. The prompt information may be the text displayed on the display screen of the server cabinet 100, or the different colors displayed by the light emitting devices on the server cabinet 100.

The remote control management console 20 controls the remote management console 20 to send its own state detection command to the BMC 31, and determines the startup state of the BMC 31 according to the return value of the BMC 31. When the BMC 31 is abnormally started or fails to start, the SEL is provided to the maintenance personnel for analysis. It can realize the rapid determination of errors during the startup of BMC31, which improves the stability and security of the server cabinet.
