Abstract

Embodiments of the present invention provide a hot swap fault recovery method and distributed equipment, which belong to the technical field of data communication. The method includes: traversing the at least one service board, and judging whether the service board having a loading fault has been loaded when it is detected that the service board having a loading fault is in place during the traversal process. Failure recovery for a preset number of times; if yes, disable the service board that has experienced a loading failure; otherwise, restart the service board that has experienced a loading failure to load again. The invention can not only ensure the recovery capability of the hot plug fault of the service board, but also ensure the stability of the distributed equipment.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a hot swap fault recovery method and distributed equipment. Background technique [0002] With the continuous development of network technology, people have higher and higher requirements on the reliability and flexibility of the network. It is necessary to use high-end distributed equipment network equipment at the core node to speed up the operation of the equipment and reduce the load pressure. When the distributed equipment is hot-swapping business boards (including line cards, switching cards, etc.), once the processing flow of a certain module is abnormal, it may cause the business board to be unable to continue loading or unloading, and even cause the main Faults such as the dead loop of related tasks on the control card, deadlock of semaphore or task suspension, etc., will eventually lead to the failure of the entire equipment system. [0003] In actual use, ...
