A hot plug configuration recovery method of rack device

Abstract

The invention discloses a restoring method of heat connecting allocation of rack-typed equipment to improve the reliability of the rack-typed business board of network communication, which comprises the following steps: A1. starting the detecting system of main control board; A2. detecting the groove position of the business board; displaying and reserving the allocating information; A3. judging whether the business board is at the groove position; reserving the allocating information of the business board at groove position; A4. restoring the allocating information of the groove position when the business board is plugged in the groove position. The invention can load and allocate the real-time allocating information in the buffer, which realizes reliable and convenient heat connecting allocation restoration.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a method for recovering the hot-swappable configuration of rack-type equipment. Background technique [0002] In the operation and maintenance process, it is common to plug and unplug the service board of rack-mounted products. It is very cumbersome to reconfigure the service board every time it is plugged and unplugged. The method for solving this problem in the prior art is to adopt hot-swap configuration recovery, which can greatly improve the maintainability of the equipment. [0003] Currently, the hot-swap configuration recovery method is usually as follows: when the service board is pulled out, each module stores its own module configuration in the cache; after the service board is inserted, each module takes out the configuration from its own cache and loads it. [0004] However, this approach has the following two problems: [0005] 1. Every time a module ...

Problems solved by technology

[0005] 1. Every time a module is added, the configuration saving and configuration recovery hook functions of the corresponding module must be added. Otherwise, the configuration of the module cannot be restored after the service board is plugged and unplugged, which increases the complexity of the implementation;

[0006] 2. If you pull out the service board, save the configuration, and then restart the system, the cache of each module has been cleared. If you insert the service board after the system startup is complete, the configuration of the service board will be lost.
