Embodiment 1

[0033] Such as figure 1 As shown, a method for detecting the stability of hard disk random hot plugging based on linux, the operation process of the method is as follows:

[0034] 1. Build a test environment: According to actual application requirements, select different types of hard disks for testing. The server needs to support hot-swappable hard disks; detect the status, capacity, SN, speed, and drive letter of the hard disk;

[0035] 2. Configure system parameters: install different operating systems according to different application scenarios, and support RHEL, Centos, and SUSE series OS; fully install the system; after the test is completed, the system can normally detect the hard disk device of the node;

[0036] 3. Select the hard disk detection tool: For the machine under test, copy the hard disk detection tool of different manufacturers; and execute the hard disk test tool to see if it can be executed normally;

[0037] 4. Perform random hot-swapping test of the h...

Embodiment 2

[0039] On the basis of Embodiment 1, the implementation steps described in this embodiment are completed in a server installed with an operating system with a linux kernel, and the user logs in as root during operation.

Embodiment 3

[0041] On the basis of Embodiment 1, the hard disk stability detection script described in this embodiment is written using a SHELL script to realize the detection of the hard disk state after the hard disk is unplugged.

Abstract

The invention discloses a Linux-based hard disk random hot plug stability detection method. The operation process of the method comprises the following steps: setting up a test environment; configuring a system parameter; installing different operating systems according to different application scenes; completely installing the systems; selecting a hard disk detect tool; performing a hard disk random hot plug operation after preparatory work is completed, and executing a hard disk stability detection script. The method is suitable for a server supporting hot plug configuration, and the stability of the server in the hard disk plug process is simulated, so that a condition that a server operating state is affected, which is caused by an abnormal hard disk state after a hard disk is replaced in the practical application process of a client is avoided. The method is simple in operation, and the operating state of the hard disk can be displayed by executing a command, so that the hard disk stability detection can be quickly realized during testing.

Description

technical field [0001] The invention relates to the technical field of hard disk stability detection, in particular to a method for detecting the stability of random hot swapping of hard disks based on Linux. 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. Because when the hard disk fails, the traditional non-hot-swappable server needs to shut down the node and then replace it, which affects the efficiency of the server; in addition, on the hot-swappable server, replacement often occurs After the hard disk, the speed of the hard disk decreases, or the order of the hard disk drifts. In this case, whether the stability of the hard disk hot swap can remain stable after the customer's late...
