Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0015] It should be noted that in the description of the present application, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0016] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0017] Specifically, Figure 1 The flowchart of a switching method for a system disk provided by an embodiment of the present application is shown. The specific steps of this method are as follows: S101. If a first system disk startup operation is detected, it is determined whether the monitoring software is enabled; wherein, the first system disk startup operation is used to boot the system through the first system disk.

[0018] In one example, before determining whether the monitoring software is enabled, the method further includes: Configuring the enabling of the monitoring software according to a preset logic.

[0019] In one example, the first system disk is a key component for booting the system. The monitoring software can be a watchdog, which is used to monitor the running state of the system. The system needs to send a signal to the watchdog regularly to indicate its normal operation. If the system fails and cannot send the signal on time, the watchdog will trigger a predefined action, such as resetting the first system disk.

[0020] In this embodiment, configuring the enabling of the monitoring software according to a preset logic, specifically, reference can be made to Table 1.

[0021] Table 1 Configuring the enabling of the monitoring software according to a preset logic

[0022] In Table 1, NA means empty, Other OS means other systems, TRUE means the monitoring software is enabled, and FALSE means the monitoring software is not enabled.

[0023] S102: When the monitoring software is enabled and a startup failure signal is received, start a timer; the startup failure signal is used to indicate that a failure occurs during the system startup process.

[0024] In one example, the startup failure signal can be os loader start. If the monitoring software is enabled and the startup failure signal is received, it means that an abnormality occurs during the system startup process, and then the timer is started for timing at this time. The advantage of such a setting is that through the redundant time, the situation of erroneously switching the second system disk or restarting the first system disk due to misjudgment can be avoided.

[0025] S103: If a startup success signal is not detected before the timer expires, determine whether there is a second system disk; the startup success signal is used to indicate that the system starts successfully during the startup process.

[0026] In one example, if a startup success signal is not detected before the timer expires, it means that the system does not start successfully, and then it is determined whether there is a second system disk at this time.

[0027] In one example, the dual-system disk architecture involves two independent system disks, one as the primary system disk and the other as the backup system disk. In this embodiment, the first system disk is used as the primary system disk. When the first system disk cannot boot the system, the backup system disk will take over to ensure the continuous availability of the system.

[0028] S104: If so, switch to boot the system through the second system disk.

[0029] In one example, the second system disk is used as the backup system disk. After determining that it is a dual-system disk, the first system disk is switched to the second system disk, and then switched to boot the system through the second system disk.

[0030] A method for switching system disks provided by an embodiment of the present application, the method includes: if a first system disk startup operation is detected, determine whether the monitoring software is enabled; wherein, the first system disk startup operation is used to boot the system through the first system disk. When the monitoring software is enabled and a startup failure signal is received, start a timer; the startup failure signal is used to indicate that a failure occurs during the system startup process. If a startup success signal is not detected before the timer expires, determine whether there is a second system disk; the startup success signal is used to indicate that the system starts successfully during the startup process. If so, switch to boot the system through the second system disk. With this technical solution, it is possible to automatically switch without manual intervention when a failure occurs during the system startup process, thereby ensuring the high availability of the computer system.

[0031] Specifically, Figure 2 The flowchart of a method for switching system disks provided by an embodiment of the present application is shown, and the specific steps of the method are as follows: S201. If a first system disk startup operation is detected, determine whether the monitoring software is enabled; wherein, the first system disk startup operation is used to boot the system through the first system disk.

[0032] In one example, after determining whether the monitoring software is enabled, the method further includes: If not, stop the switching of the system disk.

[0033] In one example, if the monitoring software is not enabled, according to the situation in Table 1, it shows that there is no need to switch the system disk at this time, so stop the switching of the system disk.

[0034] In one example, after determining whether the monitoring software is enabled, the method further includes: Configure the monitoring duration and the configured timeout times of the monitoring software; wherein, the monitoring duration is the timing period of the timer; the configured timeout times are used to represent the number of times of switching the system disk.

[0035] In one example, the monitoring duration is the duration starting from when the timer starts. Among them, the timing period is preset by the user. For example, the timing period can be 10S, the start time of the timer is 12:10:40S, then the start time of the timer is 12:10:40S, and the end time of the timer is 12:10:50S.

[0036] In one example, the configured timeout times are used to represent the number of times of switching the system disk. For example, the configured timeout times can be 3 times, which means that the maximum number of times of switching the system disk is 3 times.

[0037] In one example, after switching to boot the system through the second system disk, the method further includes: Increase the number of switches by a preset number to obtain a target number; If the target number is greater than or equal to the configured timeout number, exit the monitoring software and record the state of the first system disk at the current moment.

[0038] In one example, the preset number can be 1. That is, when the system disk is switched once, the number of switches is increased by the preset number. For example, if the initial value of the number of switches is 0, after switching to boot the system using the second system disk, the target number is 1. If the target number is greater than or equal to 3, exit the monitoring software and record the state of the first system disk at the current moment. This indicates that the system disk is frequently switched, and it is necessary to maintain and record the state of the first system disk at the current moment so that the reason for the system startup failure can be queried in a timely manner.

[0039] S202. When the monitoring software is enabled and a startup failure signal is received, start a timer; the startup failure signal is used to indicate that a failure occurs during the system startup process.

[0040] In one example, the content of this step can refer to the content of step S102 and will not be elaborated here.

[0041] S203. If a startup success signal is not detected before the timer expires, determine whether there is a second system disk; the startup success signal is used to indicate that the system starts successfully during the startup process.

[0042] In one example, the expiration of the timer means exceeding the counting period.

[0043] In one example, the method further includes: If a startup success signal is detected before the timer expires, exit the monitoring software.

[0044] In one example, if a startup success signal is detected before the timer expires, it means that the system startup is delayed, but it has started successfully before the counting period. Since the system has started successfully, exit the monitoring software.

[0045] In one example, after determining whether there is a second system disk, the method further includes: If not, restart the system to boot using the first system disk.

[0046] In one example, if there is no second system disk, it is still necessary to restart the system to boot using the first system disk. At this time, the number of switches can be increased by the preset number to obtain a target number; if the target number is greater than or equal to the configured timeout number, exit the monitoring software and record the state of the first system disk at the current moment. In this embodiment, the number of switches can also be used to represent the number of times of restarting the same system disk.

[0047] The specific startup process of the first system disk can be referred to as follows: If a startup operation of the first system disk is detected, it is determined whether the monitoring software is enabled; wherein, the startup operation of the first system disk is used to boot the system through the first system disk. When the monitoring software is enabled and a startup failure signal is received, a timer is started; the startup failure signal is used to indicate that a failure occurs during the system startup process. If a startup success signal is detected before the timer expires, the monitoring software is exited.

[0048] S204. If so, if a startup operation of the second system disk is detected, it is determined whether the monitoring software is enabled; wherein, the startup operation of the second system disk is used to boot the system through the second system disk.

[0049] In one example, the method further includes: Configure the system disk status in the startup status register of the system disk to a second preset value, and configure the status of the storage disk position register to a third preset value.

[0050] Among them, the second preset value can be 0. Further, the second preset value is used to represent that a failure occurs during the process of booting the system. This failure may occur during the process of booting the system by the first system disk or during the process of booting the system by the second system disk.

[0051] In one example, the third preset value can be 1, wherein the third preset value is used to represent the identification information of the first system disk, that is, it indicates that the first system disk is currently used to boot the system.

[0052] In this embodiment, during the process of switching to booting the system through the second system disk, the status configuration of the storage disk position register is modified from the third preset value to the fourth preset value.

[0053] Among them, the fourth preset value can be 2, and the fourth preset value represents the identification information of the second system disk, that is, it indicates that the second system disk is currently used to boot the system. In this embodiment, if the status configuration of the storage disk position register is modified from the third preset value to the fourth preset value, it indicates that the startup operation of the system is switched from the first system disk to the second system disk.

[0054] The advantage of such a setting is that it is possible to determine whether the system startup is successful by checking the system disk status in the startup status register of the system disk, and to determine which system disk is currently used to boot the system by checking the status of the storage disk position register.

[0055] S205. When the monitoring software is enabled and a startup success signal is received, configure the system disk status in the startup status register of the system disk to a first preset value, and then exit the monitoring software; where the first preset value is used to indicate that the system has started successfully during the startup process.

[0056] In this embodiment, the startup success signal indicates that the system has started successfully. If the system has started successfully, the system disk status in the startup status register of the system disk can be set to the first preset value. The first preset value is used to indicate that the system has started successfully during the startup process. Specifically, the system may be successfully booted by the first system disk or the second system disk.

[0057] S206. When the monitoring software is enabled and a startup failure signal is received, start a timer; the startup failure signal is used to indicate that a failure has occurred during the system startup process.

[0058] In one example, the content of this step can refer to the content of step S102 and will not be elaborated here.

[0059] S207. If a startup success signal is not detected before the timer expires, determine whether there is a first system disk; the startup success signal is used to indicate that the system has started successfully during the startup process.

[0060] In one example, the content of this step can refer to the content of step S103 and will not be elaborated here.

[0061] S208. If so, switch to booting the system through the first system disk.

[0062] In one example, the content of this step can refer to the content of step S104 and will not be elaborated here.

[0063] A system disk switching method provided by an embodiment of the present application includes: after switching to booting the system through the second system disk, increase the number of switches by a preset number to obtain a target number; if the target number is greater than or equal to the configured timeout number, exit the monitoring software and record the status of the first system disk at the current moment. The number of switches can also be used to represent the number of times of restarting the same system disk. With this technical solution, the system disk will not be frequently switched or restarted, and the damage rate of the system disk can be reduced.

[0065] In one example, the device 30 further includes: The third detection module 305 is used to exit the monitoring software if a startup success signal is detected before the timer expires.
