Problems solved by technology

[0004] The technical task of the present invention is to provide a method and system for locating the failure to boot due to abnormal power supply
[0007] During the start-up phase, the information collection of the PG signals of each group of voltage conversion chips by the BMC is added to ensure that when the server is abnormally powered on, the power supply module that first has the problem can be located by reading the BMC log, and then the cause of the problem can be analyzed and found.

Embodiment 1

[0025] A system for locating the failure to boot due to abnormal power supply, including power supply, BMC and multiple voltage conversion chips;

[0026] The power supply is connected in series with a plurality of voltage conversion chips through wires, and the BMC is respectively connected with each voltage conversion chip through wires.

[0027] The BMC increases the function of collecting information on each group of voltage conversion chips PG during the power-on stage.

[0028] The BMC is used for cyclically actively reading the changes of the register information of each voltage conversion chip.

[0029] Each voltage conversion chip has an access address, and the voltage conversion chip sets an address for each functional pin.

Embodiment 2

[0031] A method for locating the failure to boot due to abnormal power supply, the operation steps are as follows:

[0032] Step 1) Add the function of collecting PG information of each group of voltage conversion chips in the power-on stage to BMC;

[0033] Step 2) Use the internal registers of each voltage conversion chip to have the function of recording PG status information, collect the register information of the voltage conversion chip by reading the address of the internal register of the voltage conversion chip through the BMC, and accurately record the PG signal status of each group of voltage modules during the startup phase;

[0034] The method for the BMC to read the internal register address of the voltage conversion chip is as follows:

[0035] Each voltage conversion chip has an access address. The voltage conversion chip sets an address for each function pin. When the BMC accesses the PG information of the voltage conversion chip, it directly accesses the firs...

Abstract

The invention discloses a method and system for locating problems causing booting failure due to abnormal power supply. During booting phase, information of PG signals of each group of voltage conversion chip collected by BMC is increased. Thus, the situation that the power supply module in which the problem occurs initially is located by reading BMC log is ensured, when abnormal power-on problemsoccur on the server during booting. Then the cause of the problem is analyzed so as to find a solution. Compared with the prior art, the method and system for locating problems causing booting failure due to abnormal power supply locate the power supply module in which the problem occurs initially through the status of the PG signal sent by each group of power supply chip and collected in BMC logwhen the server can not be normally booted due to power supply problem in booting phase, and further analyze the problems and find a corresponding solution. Thus, the efficiency of research and development work is improved and the expansion of impact caused by batch problems is avoided.

Description

technical field [0001] The present invention relates to the technical field of server architecture, in particular to a method and system for locating the failure to boot due to abnormal power supply. Background technique [0002] In the era of cloud computing and big data, massive data needs to be stored and calculated, and the server deployment density in data centers is increasing. In the era of skyrocketing data volume, data is being classified and stored and calculated all the time, which places higher and higher requirements on the long-term stability and reliability of data center servers. In the product design and development stage of the server, there are the most and the most complicated problems. In particular, the failure to boot due to abnormal power supply has always taken the longest time to locate and solve problems. In the initial stage of product development, various problems can be solved as soon as possible, which can effectively shorten the product devel...
