step 108, acquiring equipment codes through the drive letter information according to the equipment drive letter and the log type and sending a log reading command;
and step 110, if the corresponding log information is successfully read, saving the read log information into a file.
Referring to a schematic diagram of communication between the hdparm and the SSD shown in fig. 2, an upper half part represents a basic functional part that is currently available, and the basic functional part can perform hard disk test and basic information acquisition, and a lower half part implements an extended function, and can perform functions such as vendor-defined log acquisition.
Specifically, because the hdparm has network open source code, the architecture of the hdparm runs in a command line mode, and no graphical interface exists, and therefore by referring to the code framework, extended functions are developed according to the framework. When inputting "hdparm-h", the introduction description of the command line parameter is returned, and the description of the extended function is added. Here, the types of the acquired logs are classified into three types of logs, including: error log, serial port log uart log, and assertion log assert log.
When hdparm is running, the command line parameter format is as follows:
sudo./hdparm–get-error-log[device]
specifically, since the tool needs root authority to execute, "sudo" needs to be added, wherein "/hdparm" indicates that the program is executed, "-get-error-log" indicates that currently acquired is error log information in the disk, [ device ] indicates the disk character of the currently operated disk, which is shaped like "/dev/sdb", and the disk character information needs to be viewed through "lsblk", and the current target disk character is found through the disk character information listed through the screen.
And finally, after the program is successfully executed, the log is printed on a screen, the log is acquired, the log is stored in a file in real time, and the program execution is finished when the log is finally printed and acquired.
In this embodiment, an extension function is added to a code frame of the hdparm, and the extension function is used for acquiring an error log, a serial port log and an assertion log respectively; when the hdparm runs, analyzing the command line parameters and judging whether the format of the command line parameters is legal or not; if the format of the command line parameter is legal, acquiring the equipment drive letter and the log type in the command line; acquiring a device code through the drive letter information according to the device drive letter and the log type and sending a log reading command; and if the corresponding log information is successfully read, saving the read log information into a file. According to the scheme, the expansion function of log acquisition is directly added into the hdparm code frame, so that the receiving and sending of the user-defined command can be realized, and the function of acquiring the expansion information in the SSD is further realized. In addition, the working efficiency can be greatly improved, and the maintenance cost is reduced.
In an embodiment, as shown in fig. 3, an SSD extended information obtaining method based on hdparm is provided, in which the step of parsing the command line parameters and determining whether the format of the command line parameters is legal when the hdparm runs includes:

step 304, if the log type is one of an error log, a serial port log or an assertion log, judging that the command line parameter is legal;
and step 306, if the log type is not one of an error log, a serial port log or an assertion log, judging that the command line parameters are illegal, and reporting an error to finish the program.
In one embodiment, as shown in fig. 4, there is provided an SSD extended information obtaining method based on hdparm, the method further includes, after the step of obtaining the device drive letter and the log type in the command line if the format of the command line parameter is legal:
step 402, judging whether the device drive letter is legal;
step 404, if the device drive letter is legal, acquiring a device code through the drive letter information according to the device drive letter and the log type, and sending a log reading command;
in step 406, if the device driver is illegal, an error is reported and the procedure is ended.
Specifically, referring to the flowchart of fig. 5 in which software executes the SSD extended information obtaining method based on hdparm, in the above embodiment, a program needs to analyze whether a command line parameter is legal at the beginning, and the format of the command line parameter is as shown in the above embodiment, which must be one of the command line parameter, that is, one of an error log, a serial port log uart log, or an assertion log assert log, otherwise, an error is reported, and the program is ended. In addition, the device drive letter needs to be legal, if the format is not correct, or the drive letter value is illegal, an error is reported to end the program. If the command line is successfully analyzed, acquiring a disk identifier and a log type of the hard disk, acquiring a device code by the program through disk identifier information, then sending a log reading command, if the command is successfully executed, recording the log information, saving the log information in a file, and if the log information acquisition fails, exiting the program.
In the embodiment, the function to be newly added can be directly added into the code frame, so that the receiving and sending of the user-defined command can be realized, the function of obtaining the expansion information in the SSD is realized, the working efficiency can be greatly improved, and the maintenance cost is reduced.
