Method for acquiring information, data storage system, electronic device, and storage medium

A data storage system comprising:

• a client, configured to send a request for acquiring device information to a server;
• a server, configured to:
• in response to the request for acquiring device information, acquire disk information of each disk device in a storage system, wherein the disk information comprises a disk identifier and a disk port address;
• acquire first mounting information of a corresponding disk by using the disk identifier, wherein the first mounting information comprises first device information of an expander upstream of the disk;
• establish, based on an expander port address comprised in the first device information, a first corresponding relationship between the expander port address with the disk port address;
• in response to the first device information comprising an adapter identifier of an adapter upstream of the expander, establish, based on an adapter port address corresponding to the adapter identifier, a second corresponding relationship between the adapter port address with the expander port address;
• and
• generate, based on the first corresponding relationship and the second corresponding relationship, device information for describing a topological relationship of the disk in the storage system;
• and
• a storage cabinet, comprising the adapter, the expander, and the disk, and configured to be connected to the server through one or more adapters, wherein one or more expanders and a plurality of disks are sequentially connected downstream of each of the adapters.

An electronic device, comprising a non-transitory storage and a processor, wherein:

• the non-transitory storage is configured to store a program;
• the processor is coupled to the non-transitory storage, and is configured to execute the program stored in the non-transitory storage, to implement following operations:
• acquiring disk information of each disk device in a storage system, wherein the disk information comprises a disk identifier and a disk port address;
• acquiring first mounting information of a corresponding disk by using the disk identifier, wherein the first mounting information comprises first device information of an expander upstream of the disk;
• establishing, based on an expander port address comprised in the first device information, a first corresponding relationship between the expander port address with the disk port address;
• in response to the first device information comprising an adapter identifier of an adapter upstream of the expander, establishing, based on an adapter port address corresponding to the adapter identifier, a second corresponding relationship between the adapter port address with the expander port address;
• and
• generating, based on the first corresponding relationship and the second corresponding relationship, device information for describing a topological relationship of the disk in the storage system.
