Problems solved by technology

[0005] With this method, when there is a problem with the system, the administrator needs to go to the computer room to open the server, install the LPC debug card, and check the stage of the problem through the error code displayed on the LPC debug card, and then judge the type of fault. Once assembled, it is difficult to install external cards on the motherboard

Embodiment 1

[0025] A method for remotely diagnosing server startup faults based on BMC, the work flow chart is as follows figure 1 As shown, the BMC chip includes a parameter storage unit, and the method for remotely diagnosing server startup faults based on the BMC includes the following steps:

[0026] Step A: The BMC creates a BMC detection module by adding codes, and the BMC detection module obtains the BIOS POST Code information in real time through the LPC bus in an interrupt mode; specifically includes the following sub-steps:

[0027] Sub-step A1: BMC sets the address of the LPC SNOOP data register to 80H;

[0028] Sub-step A2: the BMC detection module reads the value of the LPC SNOOP data register by interrupting;

[0029] Sub-step A3: When data enters at address 80H, the BMC detection module obtains the value of the LPC SNOOP data register immediately through an interrupt, and stores them in the parameter storage unit one by one.

[0030] Step B: The BMC detection module displ...

Embodiment 2

[0035] Such as figure 2 As shown, a system for remotely diagnosing server startup faults based on BMC, including a host, on which a BMC chip, Intel PCH (blue bridge chip) and RTL8211E network card are arranged on the motherboard of the host; the BMC chip is ASPEED AST2400 / 1400 BMC The chip includes an RGMII network interface, a serial port interface and a parameter storage unit; the server is provided with an IPMI LAN RJ45 interface and an RTL8211E network card, and the IPMI LAN is provided with an MDI, and the MDI is an interface of a network cable RJ45; the BMC chip passes The RGMII network interface is connected with the RTL8211E network card, and is used to send the BIOS POST Code information obtained by the BMC detection module to the BMC remote management web page through the MDI and IPMI LAN RJ45 interface connection; the serial port interface is connected with the Intel PCH , used to obtain BIOS POST Code information in real time in an interrupt manner; the parameter ...

Abstract

The present invention provides a BMC based method and system for remote diagnosis of a server startup failure. The BMC based method for remote diagnosis of a server startup failur comprises: creating a BMC detection module on a BMC by adding code, wherein the BMC detection module acquires BIOS POST Code information in real time in an interrupting manner by using an LPC bus; and the BMC detection module displaying the acquired BIOS POST Code information on a BMC remote management webpage. According to the technical scheme provided by the invention, an initialization process of each hardware device in a power-on and start-up process of a server baseboard is monitored remotely in real time, and a problem that occurs during start-up of a system can be rapidly located without the need to use a debug card, thus increasing server maintenance efficiency. Moreover, an administrator may locate the failures without going to a computer room, thereby reducing server maintenance costs and improving server maintenance efficiency.

Description

technical field [0001] The invention belongs to the field of server fault diagnosis, and in particular relates to a method and system for remotely diagnosing server startup faults based on BMC. Background technique [0002] At present, BMC (Baseboard Management Controller, Baseboard Management Controller) is used on mainstream servers for remote monitoring and management, instead of switching on and off and system monitoring operations in the computer room, and the faults that BMC can detect are limited, and many errors BMC can not detect, such as hard disk, memory, CPU problems can not be detected, and BIOS (Basic Input Output System, Basic Input Output System) POST (Power On Self Test, Power On Self Test) phase of the BIOS POST Code It is more comprehensive and can basically cover the faults of these motherboards. Wherein, described BIOS POST Code is the starting code of system BIOS. The first thing to do is to perform POST. Since there are many hardware devices in the se...
