Abstract

The invention discloses a management method of a back-end storage device, which obtains a device type of the back-end storage device. Determining a device discovery command set corresponding to the device type according to the mapping relationship between the preset device type and the device discovery command set; Cycle the execution device to discover the command set and obtain the device information of the back-end storage device. The invention can ensure the compatibility of the storage to a plurality of different protocols, types and models of back-end devices by identifying the device types of the back-end storage devices and adopting corresponding device discovery methods according to different device types. In addition, the present application also provides a management apparatus,a device, and a computer-readable storage medium of a back-end storage device having the advantages of the above technology.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a management method, device, device and computer-readable storage medium of a back-end storage device. Background technique [0002] The storage system is generally divided into a front-end (Frontend) and a back-end (Backend). The front-end is mainly used to interact with the host, receive and process commands sent by the host and related IO requests; the back-end is used to manage the back-end device (BackendDevice). Including hard disk, chassis, etc. If the local storage is connected to external storage, the backend also needs to manage the external storage, specifically, the controller that manages the external storage. [0003] Generally speaking, different policies need to be applied when performing device discovery for different backend devices. For example, for hard disks, we pay attention to information such as hard disk model, hard disk unique identification, ...
