Problems solved by technology
This will affect the normal operation of other non-failure PCIE devices in the pluggable unit, and the plugging or resetting operations need to consume more time, which affects the other components of the pluggable unit before plugging or resetting. Processing efficiency of non-faulty PCIE device services
Another existing troubleshooting method for this type of fault is to reset the computer system, which will affect all the businesses being processed by the computer system and may cause more soft faults
If the computer system is reset after waiting for the business processing of the computer system to be completed, the fault of the PCIE device that has such a fault cannot be processed as soon as possible, which reduces the efficiency of fault processing and indirectly affects the efficiency of the computer system in processing business.

The invention discloses a device fault handling method, device and system. The method is used for troubleshooting the device, and the device is a standard device for fast peripheral interconnection. The method is executed by a controller, and includes: after the controller detects a device fault, acquiring first device fault information, where the first device fault information is used to indicate the device fault. The first device fault information includes a first value of a fault processing state parameter of the device, and the first value of the fault processing state parameter of the device indicates that the device is in a soft reset state. After the controller obtains the fault information of the first device, it performs thermal reset processing on the device, avoiding human intervention to plug or reset the pluggable unit where the fast peripheral interconnection standard device is located, and avoiding artificially resetting the computer system to realize The fault handling of the fast peripheral interconnection standard equipment improves the fault handling efficiency of the fast peripheral interconnection standard equipment.
Description
technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a method, device and system for troubleshooting equipment. Background technique [0002] A computer system includes a plurality of Peripheral Component Interconnect Express (PCIE) devices connected to a processor, and many failures of the PCIE devices are caused by soft failures. For the elimination of such faults, the current method is to plug or reset the pluggable unit where the failed PCIE device is located through human intervention. This will affect the normal operation of other non-failure PCIE devices in the pluggable unit, and the plugging or resetting operations need to consume more time, which affects the other components of the pluggable unit before plugging or resetting. Processing efficiency of PCIE device services that have not failed. Another existing troubleshooting method for this type of failure is to reset the computer system, whi...
