Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, there is provided an SSD extension information obtaining method based on hdbarm, the method including:
step 102, adding an expansion function into a code frame of the hdbarm, wherein the expansion function is used for acquiring an error log, a serial port log and an assertion log respectively;
104, analyzing the command line parameters and judging whether the format of the command line parameters is legal or not when the hdpam runs;
step 106, if the format of the command line parameters is legal, obtaining the device drive letter and the log type in the command line;
step 108, obtaining a device code through the drive letter information according to the device drive letter and the log type and sending a log reading command;
step 110, if the corresponding log information is successfully read, the read log information is saved in the file.
Referring to the schematic diagram of the communication between the hdchart and the SSD shown in fig. 2, the upper half portion represents the existing basic functional portion, and may perform the hard disk test and the basic information acquisition, and the lower half portion is the implementation of the extended function, and may perform the vendor custom log acquisition and other functions.
Specifically, since hdarm is a network open source code whose architecture is running in command line mode and has no graphical interface, we will develop extended functionality according to this framework with reference to the code framework. When 'hdarm-h' is input, the description of the command line parameter is returned, and the description of the extended function is also added. Here, the types of logs obtained are classified into three types of logs, including: error log, serial log uart log and assertion log assert log.
When hdpam is running, the command line parameters format is as follows:
sudo./hdparm–get-error-log[device]
specifically, since the tool requires root rights to execute, "sudo" needs to be added, where "/hdchart" indicates that the program is executed, "-get-error-log" indicates that the in-disc error log information is currently acquired, [ device ] indicates the disc drive of the currently operated disc, like "/dev/sdb", which needs to be viewed through "lsblk" and the current target disc drive is found through the disc drive information listed on the screen.
Finally, after the program is successfully executed, the log is printed out on the screen to be obtained, the log is stored in the file in real time, and finally the log is printed out to be obtained, so that the program is completely executed.
In this embodiment, an extension function is added to a code frame of the hdpole, where the extension function is used to obtain an error log, a serial port log, and an assertion log respectively; analyzing command line parameters when the hdpam runs and judging whether the format of the command line parameters is legal or not; if the format of the command line parameters is legal, acquiring the device 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; if the corresponding log information is successfully read, the read log information is saved in the file. According to the scheme, the expansion function of log acquisition is directly added into the hdbarm code frame, so that the receiving and transmitting of the custom command can be realized, and the function of acquiring the expansion information inside the SSD is further realized. In addition, work efficiency can also be promoted greatly, maintenance cost is reduced.
In one embodiment, as shown in fig. 3, there is provided an SSD extension information obtaining method based on hdchart, wherein the steps of parsing a command line parameter and judging whether a format of the command line parameter is legal when hdchart is run include:
step 302, judging whether the log type in the command line parameters is one of an error log, a serial port log or an assertion log;
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 parameters are legal;
step 306, if the log type is not one of the error log, the serial port log or the assertion log, judging that the command line parameter is illegal, and reporting an error to end the program.
In one embodiment, as shown in fig. 4, there is provided an hdbarm-based SSD extension information obtaining method, which further includes, after the step of obtaining the device disc identifier and the log type in the command line if the format of the command line parameter is legal:
step 402, judging whether the device disc symbol is legal;
step 404, if the device disk symbol is legal, acquiring a device code through the disk symbol information according to the device disk symbol and the log type, and sending a log reading command;
step 406, if the device driver is illegal, reporting error and ending the program.
Specifically, referring to the flowchart of the method for obtaining SSD extension information based on hdchart shown in fig. 5, in the above embodiment, the program starts to analyze whether the command line parameter is legal, and the format of the command line parameter is shown in the above embodiment, and the command line parameter must be one of error log, serial log uart log or assertion log server log, or else an error is reported, and the program ends. In addition, the device disk symbol needs to be legal, if the format is not right or the disk symbol value is illegal, the error is reported to end the program. If the command line analysis is successful, the hard disk drive symbol and the log type are obtained, the program obtains the equipment code through the drive symbol information, then sends a command for reading the log, records the log information if the command is successfully executed, stores the log information into a file, and exits the program if the log information is failed to be obtained.
In the above embodiment, the function to be added can be directly added into the code frame, so that the receiving and sending of the custom command can be realized, and the function of acquiring the internal extension information of the SSD is realized.
