Abstract

The invention discloses a storage device control method and device, an electronic device and a computer readable storage medium, and the method comprises the steps: configuring an IP address for a main controller node, and controlling the main controller node to start an iSCSI service, so as to enable a server to build iSCSI connection with the main controller node; determining connection information of the iSCSI connection, and synchronizing the connection information to other controller nodes; when the main controller node fails, deleting the IP address configured for the main control node;selecting a candidate controller node from other controller nodes, and configuring an IP address for the candidate controller node; and controlling the candidate controller node to open the iSCSI service, so as to enable the candidate controller node to take over the service of the main controller node by using the connection information. According to the storage device control method provided bythe invention, the deployment process of the server is simplified on the premise of realizing the storage failure backup function.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a storage device control method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] Currently, the iSCSI (full name in Chinese: Small Computer System Interface, full name in English: Internet Small Computer System Interface) protocol is used between the server and the storage device to exchange SCSI commands. In scenarios that require high storage reliability, a storage device with dual controller nodes will be selected. The two controller nodes in the storage device are completely symmetrical. When one controller node fails, the other controller node fails for backup. Take over the iSCSI services of the faulty controller node. [0003] When deploying a storage device, you first need to configure IP addresses IP1 and IP2 on the two nodes of the storage device, and then enable the iSCSI service on both contr...
