Problems solved by technology

[0003] The problems caused by this include at least: 1) If disk A and disk B are pulled out and inserted in the opposite order, the disk numbers will be exchanged; 2) After disk A is pulled out, restarting will cause all subsequent disks to be sorted misplaced; 3) It is difficult to adjust the disk Naming; 4) It is difficult to find the abnormal hard disk through the drive letter

Abstract

The invention discloses a disk number processing method and an electronic device. The method comprises the steps of obtaining configuration information of a logic number domain, wherein the configuration information includes configuration information of a dynamic number domain and configuration information of a static number domain in the logic number domain; when a target disk is numbered, judging whether the type of the target disk is a static disk or not; when the type of the target disk is the static disk, obtaining position attribute parameters of the target disk; converting the position attribute parameters of the target disk into position attribute parameters of the corresponding static number domain; and searching for the corresponding target static number domain from the configuration information according to the position attribute parameters of the static number domain, and selecting a number for the target disk in the target static number domain.

Description

technical field [0001] The invention relates to the technical field of disk naming, in particular to a disk numbering processing method and electronic equipment. Background technique [0002] The current Linux kernel has a problem with the numbering of disks out of order, which leads to confusion in the naming of disks. Specifically, the Linux kernel's numbering scheme for disks is a dynamic allocation scheme based on the principle of preemption. When the disk controller registers a new disk with the Linux kernel, the Linux kernel always searches for a free number from number 0. Therefore, the disk numbering sequence Depends on: 1) the order in which the disks are loaded; 2) the order in which the disk controller reports the disks to the Linux kernel; 3) the bus scanning order of the peripheral component interconnection (PCI, Peripheral Component Interconnect); 4) the hot-plug order of the disk controller; 5 ) disk hot-plug sequence. [0003] The resulting problems include...
