Master-salve control method and device for dual-control storage equipment

Abstract

The invention discloses a master-salve control method for dual-control storage equipment, applied to a microcontroller unit; the microcontroller unit is connected to a master controller and slave controller in the dual-control storage equipment through a bus; the master-slave control method comprises: determining whether the master controller is abnormal or not during monitoring of operating state of the master controller; if yes, transmitting a master-slave conversion command to a slave controller so that the slave controller is upgraded into a master controller. By employing the technical scheme provided by an embodiment of the invention where the microcontroller unit is connected with the master controller and the slave controller through the bus instead of a network connection, it is possible to effectively avoid the problem that misjudgments on the operating state of the master controller due to network instability and other reasons lead to the upgrade of the slave controller into a master controller and competed use against the original master controller, and system performance of the dual-control storage equipment is improved. The invention also discloses a master-slave control device for dual-control storage equipment, having corresponding technical advantages.

Description

technical field [0001] The present invention relates to the technical field of computer storage, in particular to a dual-control storage device master-backup control method and device. Background technique [0002] With the development of computer storage technology, dual-control storage, as a storage method to ensure data reliability, has been widely used, and dual-control storage devices are gradually increasing. A dual-controller storage device includes a primary controller and a standby controller. The main controller is usually responsible for maintaining some important data, collecting chassis information and controlling the operation of chassis equipment. The standby controller takes over the work of the master controller when the master controller is abnormal, so that the dual-control storage device can operate normally. [0003] In the existing technology, such as figure 1 As shown, the main controller 100 and the standby controller 101 are respectively connected...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a dual-control storage device active-standby control method and device to effectively avoid misjudgment of the working status of the main controller due to network instability and other reasons, resulting in the upgrade of the standby controller to the main controller. And the problem of mutual contention with the original main controller occurs, improving the performance of dual-controller storage devices
