Abstract

A kind of method of testing of automatic detecting storage information and health status based on linux system of the present application.By the detection instruction in hard disk hardware to the hardware of hard disk as magnetic head, disc, motor, circuit running situation be monitored, record and with manufacturer set by default safety value compared with, if the situation of monitoring by or beyond the safe range of default safety value, can is made from trend user by the monitoring hardware or software of main frame and alerts and carry out slight automatic reparation, to ensure the safety of hard disc data in advance.

Description

Test method for automatic inspection storage information and health status of Linux system

technical field

The invention relates to the field of hard disk testing, in particular to a Linux system-based automatic inspection storage information and health state testing method.

Background technique

With the demand for mass storage technology, the capacity of disks is getting larger and larger. The technology of using a certain capacity of disks with a specific rule to create larger capacity storage through memory cards or other hardware devices continues to develop. In the storage of big data During the process, the health status of the hardware disk becomes another indispensable concern. Therefore, when each hard disk (including IDE, SATA, SCSI) is running, it records several parameters of itself, these parameters include model, capacity, temperature, density, sector, seek time, transmission, bit error rate, etc. , when the hard disk has been running for thousands of hours, many internal physical parameters will change. If a parameter exceeds the alarm threshold, it means that the hard disk is close to damage. If the user ignores this alarm and continues to use it, the hard disk will become very unreliable. Possible malfunction resulting in data loss.

Aiming at this situation, the present application invents a testing method based on the Linux system to automatically check the stored information and the health status.

Contents of the invention

The invention utilizes SMART and MegaCli tools to realize a test method for automatic detection and early warning of hard disk status.

MegaCli is a management and maintenance hardware RAID software, through which you can know all the information of the current raid card, including the model of the raid card, the array type of the raid, the status of each disk on the raid, and so on. MegaCli can perform patrol inspection, and generally use MegaCli’s Media Error Count: 0 Other Error Count: 0 to determine whether there is a problem with the disk in the array; Medai Error Count indicates that the disk may be wrong, and the disk may have bad sectors. It is worth noting that the value is not 0. The larger the value, the higher the risk factor. Other Error Count indicates that the disk may be loose and may need to be reinserted. MegaCli can detect all disks in the array and notify administrators.

Monitor and record the operating conditions of hard disk hardware such as magnetic heads, discs, motors, and circuits through detection instructions in the hard disk hardware, and compare them with the preset safety values set by the manufacturer. If the monitoring conditions will or have exceeded the expected If the safety range of the safety value is set, the monitoring hardware or software of the host computer can automatically warn the user and perform minor automatic repairs to ensure the safety of hard disk data in advance.

Specifically, the application requests protection of a test method based on Linux system to automatically inspect storage information and health status, which is characterized in that the method specifically includes the following steps:

Automatically install the MegaCli tool;

print disk properties;

Scan and print raid card id information;

Refer to the current disk status, if there is raid information, print the raid status, if not print the disk information;

View all physical disk devices FW;

Print the slot numbers corresponding to all physical disks;

Check whether the disk supports and enable smart technology, print FW, slot number, dev attribute of raid, and list FW version;

When both the hard disk and the operating system support SMART technology and are turned on, if the hard disk is in bad condition, a warning message will be displayed.

The method for testing storage information and health status based on the automatic inspection of the Linux system as described above is also characterized in that the disk information includes model, capacity, temperature, density, sector, seek time, transmission, bit error rate.

Detailed ways

The specific implementation steps of the automated testing described in the present invention will be described below through an embodiment.

The present invention is mainly used for matching raid cards on storage machines or servers, and automatically inspects corresponding information and health status of disks under the Linux system, which can realize the following functions:

1. Print disk properties;

2. Automatically install the MegaCli tool;

3. Scan and print raid card id information;

4. Refer to the current disk status, if there is raid information, print the raid status, if not print the disk information;

5. View all physical disk devices FW;

6. Print the slot numbers corresponding to all physical disks;

7. Check whether the disk supports and enable the smart technology, print the dev attribute of the raid, and list the FW version;

8. When both the hard disk and the operating system support SMART technology and are turned on, if the hard disk is in bad condition, SMART technology can display an English warning message on the screen: "WARNING: IMMEDIATLY BACKUP YOUR DATAAND REPLACE YOUR HARD DISK DRIVE, A FAILURE MAY BE IMMINENT".

Shown in accompanying drawing 1 is the flow chart of automated test described in the present invention.

1. Prepare the test environment

Hardware requirements: one server or storage machine/raid card/disk;

Software requirements: MegaCli tool, Linux system.

2. Build a test environment

Configure the raid card and the disk to be tested on the server or storage machine, enter the Linux system, copy the MegaCli tool and the automation script to the desktop, and run the test application.

The application section reads as follows:

Obviously, what is shown above is only a specific embodiment of the present invention, and for those skilled in the art, other technical solutions can also be obtained according to the above-mentioned embodiments without creative work, and in this All equivalent changes made within the protection scope of the invention shall fall within the protection scope of the present invention, and all belong to the protection scope of the present invention.

In summary, the automated testing method of the present invention is simple to implement, does not require manual operation, and truly realizes rapid automated testing, greatly improving the efficiency of R&D testing and production.
