Description

Abnormal power-off detection method, electronic device and storage medium

technical field

The invention relates to the field of power-off detection, in particular to a detection method for abnormal power-off, electronic equipment and a storage medium.

Background technique

During the SSD development process, ABRUPT SHUTDOWN needs a lot of long-term tests to ensure the stability of the SSD in an abnormal power-off environment. At present, abnormal power-off tests often use manual plugging, use hot-swappable equipment (quarch), and use relays to control the power supply Buttons and other methods, in which manual plugging and unplugging cannot achieve a large number of long-term testing requirements; quarch hot-swapping equipment cannot meet the requirements of a large number of testing because it needs to add testing equipment and is expensive, and because it is between the SSD and the host Connecting a hot-swappable device may have a negative impact on the test; using a relay to control the switch button, after testing, due to the effect of the operating system and the host power supply, there is a high probability that it will enter NORMAL SHUTDOWN, and the accurate test of abnormal power-off cannot be guaranteed. For example, if the host is idle when the power-off detection task is started, it will send a normal power-off command, and then wait for the firmware to reply. If the host is busy, after processing tasks with higher priority, if there is no power to send a normal power-off command, an abnormal power-off will be triggered.

Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

The method provided by this application can be applied to the flow diagram of the abnormal power-off detection method shown in Figure 1. First, configure the first register status to indicate that the abnormal power-off test mode is entered, and then send a formatting command to the solid-state hard disk to format The file system of the solid-state hard disk and write the first template data into the file system and send a power-off command to the solid-state hard disk, then obtain the status of the second register and determine whether the solid-state hard disk has been powered off, and then try to access the file system, and finally from the file The system acquires the second template data and generates an abnormal power-off detection result according to the second template data and the first template data.

In one embodiment, as shown in FIG. 2, the present invention provides a method for detecting abnormal power-off, which is applied to a test host, and the method includes:

S201. In response to receiving the abnormal power-off test task, configure the state of the first register to indicate entering the abnormal power-off test mode;

S202. In response to receiving a shutdown instruction, send a power-off instruction to the solid state disk according to the shutdown instruction;

S203. In response to detecting that the second register state is power-off complete, complete the shutdown operation, wherein the second register state is performed by the solid-state hard disk according to the first register state and the power-off instruction to perform a pseudo-power-off action and configuration;

S204. In response to the completion of power-on again, detect the solid-state hard disk and generate an abnormal power-off detection result of the solid-state hard disk.

Specifically, before abnormal power-off detection is performed on the solid-state hard disk, the first register A corresponding to the solid-state hard disk can be configured through pcie to realize the control of the abnormal power-off test mode. For example, when the host receives an abnormal power-off detection task, write A=1 to the first register at this time, and the solid-state hard disk will enter the abnormal power-off test mode after being informed, and the solid-state hard disk will exit the abnormal power-off test mode when the first register is written A=0 , does not affect the use after the test.

In one of the embodiments, in response to receiving the shutdown instruction, sending the power-off instruction to the solid state disk according to the shutdown instruction includes:

Send a formatting instruction to the solid-state hard disk to format the file system of the solid-state hard disk;

Writing the first template data into the file system and sending a power-off instruction to the solid-state hard disk.

Specifically, when receiving the shutdown command sent by the user, the host starts to execute the shutdown action. First, the file system ext4 (Fourth extended filesystem) of the solid-state disk is formatted, and then the solid-state disk is formatted by using the fio tool. Write the pattern, and finally issue a power-off command to the SSD.

In one of the embodiments, in response to detecting that the state of the second register is power-off completion, completing the shutdown operation includes:

Detecting the second register corresponding to the solid state disk;

Acquiring the state of the second register and determining whether the solid state disk has been powered off;

If so, continue to complete the shutdown operation;

If not, the state of the second register is reacquired.

Specifically, as described above, after the test host sends a power-off command to the solid-state hard disk, the test host continues to obtain the state of the second register B corresponding to the solid-state hard disk. If it is detected that the second register shows that the solid-state hard disk has been powered off, Then the test host officially completes the shutdown operation, that is, other components in the host are also powered off. And when the second register B shows that the solid-state hard drive has not been powered off, you can first power off other components and then re-acquire the status of the second register B until the solid-state hard drive is powered off and the host completes the shutdown action.

In one of the embodiments, in response to the completion of power-on again, detecting the solid-state hard disk and generating the abnormal power-off detection result of the solid-state hard disk includes:

If successful, acquire second template data from the file system, and generate the abnormal power-off detection result according to the second template data and the first template data.

Specifically, the test host can complete the power-on and start-up through the relay control switch button. At this time, the solid-state hard drive is also successfully powered on. At this time, the test host tries to access the file system of the solid-state hard drive. If the file system cannot be accessed or is not detected, then It is determined that the solid-state drive is not mounted normally after the abnormal power-off test, and the user needs to be alerted at this time. If the file system is successfully detected and accessed, the test host obtains the pattern (second template data) after the abnormal power-off test from the file system and generates the final abnormal power-off detection result by comparing the two data.

In one of the embodiments, the generating the abnormal power-off detection result according to the second template data and the first template data includes:

determining whether the first template data and the second template data are the same;

If so, generate a first abnormal power-off detection result and send the first abnormal power-off detection result to the user;

If not, generate a second abnormal power-off detection result and send the second abnormal power-off detection result to the user.

Specifically, as mentioned above, after the second template data is successfully obtained, the original pattern (first template data) written into the file system before power-on and booting is compared with the second template data, and when the error between the two is less than For example, if it is within 1%, it means that the abnormal power-off detection of the solid-state drive is normal (the first abnormal power-off detection) and sent to the user. When the error between the two is greater than or equal to, for example, within 1%, it means that the abnormal power-off detection of the solid-state drive is abnormal (Second abnormal power-off detection) and sent to the user, wherein the error coefficient can be set by the user.

S303. Perform a pseudo power-off action according to the state of the first register and the power-off instruction;

S304. Configure the state of the second register to indicate that the solid state disk is powered off.

Specifically, when receiving and testing the power-off command sent by the host, the state of the first register A is obtained. If A=1, the solid-state hard disk enters the abnormal power-off test mode. At this time, the received power-off command is pseudo-down electric action. Including modifying the state of the corresponding second register to have been powered off, but not actually powering off its own file system, that is, when the host is turned off, the SSD does not perform a real power-off action and only modifies the state of the second register.

In one embodiment, the method also includes:

S305. Formatting the file system of the solid-state hard disk in response to receiving the formatting instruction issued by the test host;

S306. Receive the first template data sent by the test host and write it into the file system.

In one embodiment, the method also includes:

S307. In response to the test data reading request sent by the test host after power-on is completed, send the second template data to the test host, so that the test host can use the first template data and the second template data The abnormal power-off detection result is generated.

Specifically, as described above, after the solid state hard drive is powered on again, when the test data reading request sent by the host is received, the pattern (second template data) that has been powered off and powered on in the file system is sent It is used for the test host to compare and generate abnormal power-off detection results.

The scheme of the present application has the following beneficial effects:

1) It solves the problem that using the relay to control the switch button cannot guarantee that the abnormal power-off will occur every time the machine is shut down, and improves the precise control of the abnormal power-off test;

2) Compared with using quarch and other hot-swap test equipment, the test cost is reduced, and abnormal power-off tests of a large number of devices can be realized.
