Redundant device and test method and system thereof and storage medium

Abstract

The invention discloses a redundant device and a test method and system thereof and a computer readable storage medium. The redundant device comprises a plurality of devices redundant to each other, and all the device redundant to each other is provided with controllers; and the controllers are used for controlling shutdown of the devices during receiving control instructions of a main controller.According to the redundant device, only one control bus interface is needed to finish the shutdown of a special redundant device or components and operation state information of all components of a whole machine after the shutdown, manual costs of manual mechanical operation are reduced, test bugs caused by manual operational faults are reduced, and the test efficiency and accuracy are greatly improved. In addition, the situation that singular redundant devices in all groups are subjected to shutdown operation simultaneously through the main controller can be achieved, the deficiency that themanual mechanical operation cannot simultaneously perform mechanical disassembly on the multiple devices at the same time is made up, and batch tests are benefited.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a redundant device, its testing method, system, and a computer-readable storage medium. Background technique [0002] The key components of high-reliability equipment will adopt dual redundant design, that is, key components such as controllers or power supplies use dual redundant controllers or dual redundant power supplies. During normal operation, two key components with the same function are mutually backup or one is The role of the master and the backup is that when one of the key components fails, the other key components that are mutually backup can continue the current business, so that the current business will not be interrupted due to the failure of the only key component. [0003] The dual redundant design of mutual backup greatly improves the reliability of the system, but the simplest and direct verification method for the dual redundant functio...

AI Technical Summary

Problems solved by technology

[0003] The dual redundant design of mutual backup greatly improves the reliability of the system, but the simplest and direct verification method for the dual redundant function during system design and assembly is nothing more than directly removing one of the key components, such as the directly disassembled The controller or power supply can be pulled out from the chassis directly by manpower

However, this method is not only labor-intensive. Once the number of the whole machine is large and the key components that are redundant with each other increase, the workload will be time-consuming and labor-intensive. Moreover, the disassembly of the key components by direct manual machinery will bring mechanical loss and man-made damage to the whole machine. Operational unreliability, etc.

What's more, some redundant key components will be extremely inconvenient to manually disassemble after assembling the complete machine
