Embodiment 1

[0024] The method for adjusting the order of disks between multiple controllers under the linux system described in this embodiment, the specific process of each step is as follows:

[0025] 1) Check the driver name of each controller

[0026] Different configurations have different types of memory cards, and the loaded driver names are also different, so it is necessary to determine the driver names of the relevant controllers in advance. Check the device number of the corresponding card under the system to find the corresponding driver name;

Abstract

The invention discloses a method for adjusting the sequence of disks among multiple controllers in a Linux system, and relates to the technical field of computer servers. The specific implementation process is as follows: checking the driver names of each controller; determining the driver loading sequence; and writing a driver loading sequence configuration file according to requirements ; Back up the original boot file of the system; recompile the boot file; restart the system to complete the adjustment. This method can be applied to various configurations, and the disk sequence can be adjusted flexibly and conveniently according to different application scenarios to meet different customer needs.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a method for adjusting the sequence of disks among multiple controllers under the Linux system. Background technique [0002] With the continuous development of technology in the IT field, traditional information services and increasingly powerful cloud computing services have increasingly complex server requirements. As a server product provider, the quality of a server lies in whether it can meet different application requirements. Due to the continuous increase of storage information capacity, the disk on a single server cannot meet the demand, and different external storage devices need to be connected through different memory cards to meet the demand for disk capacity. As the types of external memory cards increase, the requirements for the order of the disks also arise. For different application scenarios, there are different requirements for the order of the disk...
