Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.

Referring to fig. 1, a first flowchart illustrating a first step of a PCIE device failure monitoring method provided in an embodiment of the present invention is applied to a BMC, where the method may include:

step 101, when detecting that a fault report sent by a basic input output system BIOS is received, acquiring target serial number information corresponding to the fault report.

It should be noted that, in the embodiment of the present invention, a Basic Input Output System (BIOS), which is a set of programs solidified on a ROM chip on a main board in a computer, stores the most important Basic Input and Output programs of the computer, system setting information, a self-test after power on program, and a System self-boot program. The BIOS can receive Advanced Error Reporting (AER), and the AER is the Advanced characteristic of PCIE and is used for Reporting PCIE Error information.

It should be noted that, in the embodiment of the present invention, it is to be noted that the PCIE device needs to satisfy the capability of reporting the failure, that is, the PCIE Switch firmware needs to support the AER, and both the Switch error and the PCI endpoint error below the Switch belong to the standard PCI error.

Further, a PCIE Switch provides expansion or aggregation capability, allows more devices to be connected to a PCle port, can serve as a packet router, identifies which path a given packet needs to go along based on address or other routing information, and is a PCIE-to-PCIE bridge.

Therefore, when PCIE ERROR occurs, that is, when PCIE fault occurs, PCIE reports to a BIOS, and the BIOS sends the fault report to a substrate Management Controller (BMC), where hardware in the BMC uses an SOC chip with arm9 as a core, and software is developed based on base code provided by AMI or Avocent. The BMC mainly provides monitoring of temperature, voltage, fans and buses for the server and provides a management interface so that a user can remotely control the server through the BMC.

It should be noted that, in the embodiment of the present invention, the failure report is an AER, the target serial number information is a serial number corresponding to the AER, the serial number refers to a unique identifier of the PCIE Device and may be represented as a BDF (Bus Device Function), and each PCIE Device may have only one Function, that is, fun0. It is also possible to have up to 8 functions, i.e. a multi-function device. Regardless of how many functions the PCIE device has, each function has a unique and independent configuration space corresponding to it, and like the PCIE bus, each function in the PCIE bus has a unique identifier corresponding to it. This identifier is the BDF, and the PCIE configuration software should be able to identify the topology logic of the entire PCIE Bus system, as well as each Bus (Bus), each Device (Device) and each Function (Function) therein.

In addition, besides the serial number information, an identifier is also provided for the PCIE devices to indicate, where the identifier is an identifier preset for each PCIE device before the BMC allocates the BDF to the PCIE device, and is used to assist the operation and maintenance personnel to find the PCIE hardware location more quickly. The identifier may be represented as a BOARD ID, and a corresponding relationship needs to be established between the BDF and the BOARD ID, and specific details of how the relationship is established may be described in detail with reference to the following embodiments.

Therefore, when detecting that a fault report sent by the BIOS is received, the BMC needs to obtain target serial number information corresponding to the fault report at this time, and it should be noted that the target serial number information is serial number information included in the fault report in the serial number information.

And step 102, determining a target identifier in a PCIE equipment mapping relation table according to the target serial number information.

It should be noted that, in step 101, in the embodiment of the present invention, the target serial number information is obtained, and the target serial number information may be searched in a PCIE device mapping relationship table according to the target serial number information, where a one-to-one correspondence relationship between BDF and BOARD ID is stored in the PCIE device mapping relationship table, and therefore, the target identifier corresponding to the target serial number information may be found in the PCIE device mapping relationship table according to the target serial number information.

And 103, acquiring PCIE equipment information corresponding to the fault report according to the target serial number information and the target identifier.

It should be noted that, in the embodiment of the present invention, after the target serial number information and the target identifier are determined, the PCIE device corresponding to the failure report may be determined, and then the PCIE device information is obtained.

Further, the obtaining, according to the target sequence number information and the target identifier, PCIE device information corresponding to the failure report includes: generating an IPMI command according to the target serial number information and the target identifier; and acquiring register information of the PCIE equipment corresponding to the fault report and a fault position according to the IPMI command.

It should be noted that, in the embodiment of the present invention, the PCIE device information includes register information and a fault location, and therefore, the target serial number information and the target identifier are written into the IPMI command, where IPMI is a command language of PCIE Switch, and an operation and maintenance worker can write the IPMI command by writing a script to view the PCIE device information, and therefore, the IPMI command can be generated according to the target serial number information and the target identifier; and checking register information of the PCIE equipment corresponding to the fault report and the fault position according to the IPMI command.

In the method for monitoring the failure of the PCIE device provided in the embodiment of the present invention, when detecting that a failure report sent by a BIOS is received, target sequence number information corresponding to the failure report is obtained; determining a target identifier according to the target sequence number information in a PCIE equipment mapping relation table; and acquiring PCIE equipment information corresponding to the fault report according to the target serial number information and the target identifier. In the embodiment of the invention, the target serial number information is obtained by receiving the fault report, the identifier is searched in the pre-generated mapping relation table, and the PCIE equipment information corresponding to the fault report is obtained according to the serial number information and the identifier information, so that the state of the specific PCIE equipment in the server based on the PCIE Switch architecture is effectively monitored in real time, and a good fault monitoring and diagnosing means is provided for the operation and maintenance work after the server is on-line and even mass production.

Referring to fig. 2, a flowchart showing a second step of the PCIE device failure monitoring method provided in the embodiment of the present invention is applied to a baseboard management controller BMC, where the method may include:

and 001, acquiring serial number information of PCIE equipment in the server.

And 002, matching the serial number information with a preset identifier to generate a PCIE device mapping relationship table.

It should be noted that, in the above steps 001-002, the BMC may first match the BOARD ID and the BDF of the PCIE Switch through the uart serial port, where the serial number refers to a unique identifier of the PCIE Device and may be represented as a BDF (Bus Device Function), and each PCIE Device may have only one Function, that is, fun0. It is also possible to have a maximum of 8 functions, i.e. a multi-function device. Regardless of how many functions the PCIE device has, each function has a unique and independent configuration space corresponding to it, and like the PCIE bus, each function in the PCIE bus has a unique identifier corresponding to it. The identifier is the BDF, the PCIE configuration software should have the capability of identifying the topology logic of the entire PCIE Bus system, and each Bus (Bus), each Device (Device) and each Function (Function) therein, and the PCIE Device is also represented by an identifier, where the identifier is an identifier preset for each PCIE Device before the BMC allocates the BDF to the PCIE, and is used to assist the operation and maintenance staff to find the PCIE hardware position faster, and the identifier may be represented as a bow ID.

Step 101, under the condition that a fault report sent by a basic input output system BIOS is detected to be received, target serial number information corresponding to the fault report is acquired.

It should be noted that, the above steps 101-103 are discussed with reference to the preamble, and are not described herein again.

It should be noted that, in the embodiment of the present invention, after the PCIE device information is acquired, the PCIE device may be adaptively corrected, specifically, when a register value in the PCIE device information is abnormal, the PCIE device may be adaptively corrected according to a preset PCIE specification.

The adaptive correction is to perform neural network learning based on historical failure information of the PCIE equipment, and when the same or similar failure is encountered next time, the PCIE equipment can be automatically adjusted based on a historical processing method, so that the normal work of the server is prevented from being influenced.

Further, after the step of obtaining the PCIE device information corresponding to the failure report according to the target sequence number information and the target identifier, the method may further include: and visually displaying the PCIE equipment information on a preset management interface of the BMC.

It should be noted that, in the embodiment of the present invention, PCIE device information may also be visually displayed on a preset management interface of the BMC, where the preset management interface may be a BMC WEB or other preset WEB pages, and the PCIE device information is visually displayed through a code, which is convenient for an operation and maintenance worker to capture the PCIE device, locate the fault information, and display the fault through the preset management interface.

Further, after the step of obtaining the PCIE device information corresponding to the failure report according to the target sequence number information and the target identifier, the method may further include: and generating a black box log according to the register information in the PCIE equipment information, and storing the black box log.

It should be noted that, in the embodiment of the present invention, the information of the PCIE device register is collected to form the black box log, which is convenient for data analysis to the PCIE engineer, and in addition, the one-key log collection may be further collected, specifically, the BIOS may collect the log information and send the log information to the BMC.

It should be noted that the black box log may record a value of a register, and the register may be subsequently analyzed according to the value of the register. If the type of the failure information of the PCIE is an uncorrectable fault error, these errors may have a great influence on the system, and generally accompany with downtime, restart, kernel panel, and the like, so the BMC may control the display of the error indicator lamp besides recording the errors, thereby notifying the operation and maintenance of a serious failure and urgently requiring repair. If the analyzed errors are correct non-normal error and correct error, the BMC records the value of the register and the fault position information in the black box log.

In the method for monitoring the failure of the PCIE device provided in the embodiment of the present invention, when detecting that a failure report sent by a BIOS is received, target sequence number information corresponding to the failure report is obtained; determining a target identifier in a PCIE equipment mapping relation table according to the target sequence number information; and acquiring PCIE equipment information corresponding to the fault report according to the target serial number information and the target identifier.
