Peripheral component high-speed interconnection equipment fault detection method and device and server

Abstract

The invention provides a PCIE equipment fault detection method, a device and a server.The server comprises a CPU and a BMC, and the BMC receives equipment information of in-place PCIE equipment collected by the CPU; equipment information of the PCIE equipment supporting the MCTP on the PCIE bus is obtained; determining a PCIE device to be detected according to the obtained device information of the in-place PCIE device and the device information of the PCIE device supporting the MCTP; and performing fault detection on the to-be-detected PCIE device, and determining a fault PCIE device in a fault state. According to the PCIE equipment fault detection method and device, the BMC does not only depend on a BIOS interrupt service program to detect the PCIE equipment fault, the BMC can actively determine the to-be-detected PCIE equipment and perform fault detection on the to-be-detected PCIE equipment, so that the fault detection means of the PCIE equipment is expanded. The system fault diagnosis rate can be effectively improved.

Description

technical field [0001] The present application relates to fault diagnosis technology, in particular to a PCIE device fault detection method, device and server. Background technique [0002] The BMC (Baseboard Management Controller, Baseboard Management Controller) is mainly to monitor and report the faults of various components of the server in time to ensure the reliable operation of the server. At present, BMC's fault detection for PCIE (Peripheral Component Interconnect Express, high-speed interconnection of peripheral components) devices such as network cards and GPU (graphics processing unit, graphics processing unit) cards mainly depends on the processor on the server through BIOS (Basic Input Output System, basic input and output The interrupt service program of the system) detects the interrupt fault of the PCIE device to report the fault interrupt of the PCIE device, and passes it to the BMC through the BIOS. [0003] However, in practical applications, due to the ...

Problems solved by technology

[0003] However, in practical applications, due to the various types of faults of PCIE devices, some faults may not be detected by the interrupt of the fault detection of the PCIE device by the processor on the server. For example, if a PCIE device fails, the operating system will process the PCIE device offline , resulting in the loss of the PCIE device, but this kind of failure has not been detected by the BIOS interrupt service program, and it will not be sent to the BMC. That is to say, neither the processor nor the BMC on the server has detected this type of failure. The PCIE device with this type of fault is missed, resulting in a low system fault diagnosis rate
