Dual-port hard disk hot plug control method and device, controller and medium

Abstract

The application discloses a dual-port hard disk hot plug control method and device, a controller and a medium, relates to the technical field of servers, and comprises the following steps: when detecting a hard disk hot insertion behavior, determining a hot plug management mode and a target controller board; determining a target hard disk and controlling the target hard disk to be powered on; informing the target controller board that the hard disk hot plug behavior occurs; sending a reset signal sent by the target controller to the target hard disk to complete hard disk reset; and sending an output enable signal to a hot plug buffer corresponding to the target hard disk to connect the target hard disk with a bus. Since the dual-active mode and the master-slave mode are compatible, the dual-active mode can fully utilize the broadband resources of the dual-port hard disk, and the technical problem of waste of the bandwidth resources of the dual-port hard disk is solved; the master-slave mode is beneficial to improving the reliability of a multi-mainboard server system, switching between the dual-active mode and the master-slave mode according to requirements, and improving the flexibility and adaptability of the multi-controller board server.
