Method and device for detecting hard disk disorder based on Linux system

Abstract

The invention provides a method and device for detecting hard disk disorder based on a Linux system. The method for detecting hard disk disorder includes the following steps that for each to-be-detected hard disk, the standard correspondence relationship of bus IDs of the to-be-detected hard disk and hard disk drives of the to-be-detected hard disk is built; A1, a server connected with the to-be-detected hard disk is started; A2, a hard disk drive sequence script is obtained through triggering, and for each to-be-detected hard disk, the current correspondence relationship of the bus IDs of the to-be-detected hard disk and the hard disk drives of the to-be-detected hard disk is obtained; A3, on the premise that the bus ID is the same one, the current correspondence relationship is compared with the standard correspondence relationship, and if there are at least two current correspondence relationships different from the standard correspondence relationship, the detection result is recorded as disorder; A4, the number of times of disorder and the number of times of detection are recorded, the A1 step is executed until a stopping command is received from the outside, the current process is stopped, and the number of times of disorder and the number of times of detection are displayed. The method and the device can be used for detecting whether hard disk drive disorder occurs in the hard disk in the server or not.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for detecting out-of-sequence of a hard disk based on a Linux system. Background technique [0002] In the Linux system, in order to distinguish the hard disks connected to the system, each connected hard disk is assigned a bus ID and a hard disk drive letter. Among them, the bus ID assigned by the system to the hard disk is unchanged, and the drive letter assigned by the system to the hard disk will change due to the different startup sequences of the hard disk. [0003] This allocation method of the hard disk drive letter will cause the corresponding hard disk drive letter of the hard disk to change, thus causing the hard disk drive letter to be out of sequence. Disordering of hard drive letters will have a negative impact on server performance. For example, the drive letter corresponding to hard disk A is sda, and the drive letter corresponding to hard ...

AI Technical Summary

Problems solved by technology

At present, there is no clear method to detect whether the hard drive letters in the server will be out of order, so it is necessary to develop a method that can detect whether the hard drives in the server will be out of order
