Description
Technical Field
The invention relates to the technical field of servers, in particular to a method and a device for starting a serial port log and a computer readable storage medium.
Background
With the advent of big data, cloud computing and artificial intelligence era, the internet traffic and data volume are dramatically increased, the carrying pressure of a server is higher and higher, and the requirement on the link stability of the whole system is higher and higher. The health state of the server in the power-on starting and running processes needs to be monitored in real time, slight errors can be corrected through a verification mechanism in the starting and running processes, the influence on the running of the server is small, if serious faults occur, the system can be down, and the caused consequences are service interruption of a client, data loss and unpredictable loss.
The operation of the server is divided into two stages, namely a Power On Self Test (POST) stage and a system operation stage, wherein the two stages are closely connected. In the POST stage, after the server is powered on, a Basic Input Output System (BIOS) detects and initializes hardware of the server, the BIOS plays a leading role in the process, the BIOS starts to find and boot the System after the BIOS self-inspection is completed, at this time, the BIOS transfers control to the System, and the BIOS only has Basic functions such as interrupt processing.
After the control right is transferred to the system, some faults occurring in the server may be recorded in a system log and a Baseboard Management Controller (BMC) log, and the system log and the BMC log may be analyzed to perform problem location analysis. However, in the POST process, because the logs recorded and transmitted to the BMC by the BIOS are very few, and there is no place to record fault logs in relation to the BIOS code, there is no way to analyze and locate the fault if a serious fault such as downtime occurs in the POST process.
The most effective way to analyze such problems is to export the serial log of the BIOS during the POST process, which requires turning on the debug mode of the BIOS, which is off by default. If it is to be turned on, the BIOS version needs to be redeveloped and refreshed on the failed server, which results in the disappearance of the failure phenomenon.
Therefore, how to implement the fault detection of the power-on self-test is a problem to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a method for starting a serial log according to an embodiment of the present invention is described in detail. Fig. 1 is a flowchart of a method for starting a serial port log according to an embodiment of the present invention, where the method includes:
s101: and when the server does not finish the power-on self-test within the preset starting time, restarting the server and recording the restarting times.
The preset starting time can be set according to the time required by the power-on self-test when the server operates normally. For example, the preset activation time may be set to 6 minutes. The power-on self-test process can be completed within 6 minutes when the server is normally running.
And when the power-on self-test is not completed within the preset starting time after the server is started, the power-on self-test is abnormal.
The abnormality of the power-on self-test may be a transient abnormality or a fault abnormality. For transient abnormity, the server is restarted to solve the problem, and the server enters a power-on self-test stage after being restarted to complete power-on self-test within preset starting time.
For the fault abnormity, the problem often cannot be solved by restarting the server, the server enters a power-on self-test stage after being restarted, and when the server still cannot complete the power-on self-test within the preset starting time, the server can be restarted again. And adding 1 to the corresponding restart times of the server every time the server is restarted.
S102: and judging whether the restarting times of the server in the preset time period are greater than or equal to a preset threshold value.
The server is restarted once, so that when the power-on self-test is completed within the preset starting time, the last power-on self-test failure is caused by the transient abnormality of the server, and at the moment, the recording of the serial port log in the power-on self-test process is not required. Therefore, in the embodiment of the present invention, the value of the preset threshold is certainly greater than 1. For example, the preset threshold may be set to 2.
The preset time period may be set by integrating the time spent by the power-on self-test when the server operates normally and a preset threshold, for example, the preset time period may be set to 30 minutes.
The influence of the transient abnormality of the server on the power-on self-test can be reduced by setting a preset threshold value to judge the restarting times.
When the restart time of the server is greater than or equal to the preset threshold within the preset time period, it indicates that the power-on self-test is a fault abnormality, and at this time, S103 may be executed. When the restarting frequency of the server in the preset time period is smaller than the preset threshold value, the server can successfully complete the power-on self-test, the operation can be ended, and the server enters the system operation stage.
Taking the preset threshold value as 2 and the preset time period as 30 minutes as an example, when the server is restarted for the first time, the number of times of restarting is 1, and if the server still cannot complete the power-on self-test within the preset starting time after the first restart, the server is restarted for the second time, and at this time, the number of times of restarting is 2. When the server is restarted for the second time, the number of times of restarting reaches the preset threshold, and if the time interval between the first time of restarting the server and the second time of restarting the server is less than 30 minutes, it indicates that the server has executed continuous restarting for many times in a short time, and at this time, S103 may be executed.
S103: and starting a log recording mode of power-on self-test.
In the embodiment of the invention, a power-on self-test log recording program can be preset, and when the log recording mode is started, the power-on self-test log recording program starts to run, so that the serial port log of the server in the power-on self-test process is recorded.
In a specific implementation, the logging mode may be initiated by setting a flag bit. The flag bits can be divided into valid flag bits and invalid flag bits, for example, the valid flag bits can be represented by the number 1, and the invalid flag bits can be represented by the number 0.
When the flag bit of the power-on self-test log recording program is adjusted to be an effective flag bit, the server starts a log recording mode during power-on self-test, and therefore serial port logs in the power-on self-test process of the server are recorded.
In S101, the number of restarts is recorded, where there are various ways to record the number of restarts, one way may be recording by using a register, and another way may be setting a watchdog program. The watchdog program can realize the function of timing detection, and the watchdog program can be started once to detect whether the power-on self-check is completed within the preset starting time after the server is restarted. The number of times the watchdog program is started is the number of times the server is restarted.
In specific implementation, when the server is started, whether the server completes power-on self-test within preset starting time can be judged; and when the server cannot complete the power-on self-test within the preset starting time, restarting the server, triggering a preset watchdog program, and detecting whether the server completes the power-on self-test within the preset starting time by using the watchdog program.
Accordingly, it can be determined whether the number of times the watchdog program is triggered within the preset time period is greater than or equal to the preset threshold. When the number of times of the watchdog program being triggered within the preset time period is greater than or equal to the preset threshold, S103 is executed.
By setting the watchdog program, whether the server completes power-on self-test within the preset starting time can be detected, the starting times of the watchdog program can be used as the restarting times of the server, and extra storage resources are not required to be spent for recording the restarting times of the server.
According to the technical scheme, when the server does not finish the power-on self-test within the preset starting time, the fact that the power-on self-test process is abnormal is indicated, the server can be restarted at the moment, and the restarting times are recorded. And adding 1 to the restart times every time the server is restarted, and judging whether the restart times of the server in a preset time period are greater than or equal to a preset threshold value. When the restart times of the server in a preset time period are greater than or equal to a preset threshold value, it indicates that the power-on self-test abnormality still exists when the server is continuously restarted for multiple times, at this time, a log recording mode of the power-on self-test can be started, and a serial port log of the power-on self-test process after the server is restarted is recorded. In the technical scheme, when the power-on self-test is normally operated, the log recording mode of the power-on self-test is not started, and the server executes the power-on self-test according to the conventional power-on self-test process without spending too long time. And only when the power-on self-test process of the server is judged to be abnormal, starting a log recording mode of the power-on self-test to record a serial port log of the power-on self-test process, so that the fault detection of the power-on self-test is realized.
In practical application, the abnormality of the power-on self-test of the server is not always continuous through the maintenance of management personnel. If the log recording mode of the power-on self-test is always started, it takes a long time to perform the power-on self-test after each time the server is powered on and started. Therefore, in the embodiment of the present invention, after the log recording mode of the power-on self-test is started, the log recording mode of the power-on self-test may be closed when it is determined that the power-on self-test of the server is restored to the normal working state.
The trigger condition for closing the logging mode of the power-on self test can be various.
In combination with the above described watchdog program, a feasible way may be to determine whether the watchdog program is triggered within the second preset time period.
When the server does not complete the power-on self-test within the preset starting time, the watchdog program is triggered when the server is restarted.
In practical application, except for the restart of the server when the power-on self-test is abnormal, the server can also execute normal power-on restart due to service requirements.
After the server starts the log recording mode of the power-on self-test, timing is carried out when the server is powered on and restarted, or timing is started when the server triggers the watchdog program for the first time, when the watchdog program is not triggered in a second preset time period, the situation that the server is not abnormal in the power-on self-test does not occur in the second preset time period, and at the moment, the log recording mode of the power-on self-test can be closed.
The value of the second preset time period is greater than the value of the preset time period in S102, for example, the second preset time period may be set to 60 minutes.
After the server starts the log recording mode of the power-on self-test, taking the example that the server starts timing when the server triggers the watchdog program for the first time, if the watchdog program is not triggered again by the server within 60 minutes, the power-on self-test process of the server is recovered to be normal, and at this time, the log recording mode of the power-on self-test can be closed.
The second feasible trigger condition may be that after the log recording mode of the power-on self-test is started, when the server restarts and completes the power-on self-test, it is determined whether the time interval between the current restart time and the last restart time of the server is greater than or equal to a preset time limit value.
After the server starts a log recording mode of the power-on self-test, if the server still has the abnormal condition of the power-on self-test, the server can execute a plurality of times of restarting operations in a short time. Therefore, if the time interval between the current restart time and the last server restart time is greater than or equal to the preset time limit, it indicates that the server restart belongs to the normal service requirement, and the server restart is not caused by abnormal power-on self-test, the power-on self-test process of the server is recovered to be normal, and at this time, the log recording mode of the power-on self-test can be closed.
The third feasible trigger condition may be that after the log recording mode of the power-on self-test is started, when the server has no abnormality in the power-on self-test for two consecutive times, the log recording mode of the power-on self-test is closed.
It should be noted that, in the embodiment of the present invention, two consecutive power-on self-tests of the server do not have an abnormality, rather than the server executes two power-on self-tests within a short time, the two power-on self-tests may have a time interval, and the two consecutive power-on self-tests refer to two power-on self-tests that are adjacent in time.
When no abnormity occurs in the two continuous power-on self-tests, the power-on self-test process of the server is recovered to be normal, and at the moment, the log recording mode of the power-on self-test can be closed.
For closing the log recording mode of the power-on self-test, in a specific implementation, a flag bit of a preset power-on self-test log recording program may be adjusted to be an invalid flag bit, so that the log recording mode is in a closed state when the server is in the power-on self-test.
After the log recording mode of the power-on self-test is started, the working state of the power-on self-test of the server is detected, so that the log recording mode of the power-on self-test can be closed in time when the power-on self-test of the server is recovered to be normal, and the influence of long-time starting of the log recording mode on the power-on self-test time is reduced.
