Fault isolation method, device and equipment and computer readable storage medium

Abstract

The invention discloses a fault isolation method, device and equipment and a computer readable storage medium. According to the method and the device, after computer equipment is restarted, the data transmission capability of PCIE equipment causing the error report of the restart can be degraded; no matter how much the data transmission capability of a certain data transmission channel of the error-reporting PCIE equipment is lost, after degradation, the requirement of the PCIE equipment for the data transmission capacity of a faulty data transmission channel in the PCIE equipment is possiblynot greater than the remaining capacity of the PCIE equipment, so that the PCIE equipment does not report errors any more, the computer equipment can normally operate original services, and the working efficiency is improved; besides, the corresponding relationship between the preset number of error reporting times and the degradation level is a positive correlation relationship, so that the degradation degree of the data transmission capability can be gradually improved, the data transmission capability of the error-reporting PCIE equipment can be reduced as little as possible, and the residual performance of the PCIE equipment can be utilized to the maximum extent.

Description

technical field [0001] The present invention relates to the field of computer equipment, in particular to a fault isolation method, and also relates to a fault isolation device, equipment and computer-readable storage medium. Background technique [0002] Computer devices (such as servers) are usually connected to some PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) devices to enhance computing, storage or network functions. During the use of PCIE devices, with long-term operation and Due to the aging of the equipment, the PCIE device is likely to report an error. In the face of the PCIE device error, the computer device usually tries to fix the problem of the PCIE device by restarting and re-initializing the PCIE device, but it may not work. , that is, the error of the PCIE device still exists after restarting. In this case, due to the error report of the PCIE device, the computer device will fall into a state of continuou...

[0002] Computer devices (such as servers) are usually connected to some PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) devices to enhance computing, storage or network functions. During the use of PCIE devices, with long-term operation and Due to the aging of the equipment, the PCIE device is likely to report an error. In the face of the PCIE device error, the computer device usually tries to fix the problem of the PCIE device by restarting and re-initializing the PCIE device, but it may not work. , that is, the error of the PCIE device still exists after restarting. In this case, due to the error report of the PCIE device, the computer device will fall into a state of continuous restart, unable to perform the original business normally, and reduce work efficiency.
