Description

Technical Field

[0001] The present invention relates to the field of equipment operation and maintenance technology, and in particular to a method, device, equipment and storage medium for repairing equipment firmware. Background Art

[0002] Iterative updates of BIOS (Basic Input Output System) usually introduce new features and fixes. However, due to the improvement of features, some BIOS setup (configuration item) values ​​may be applicable in the old BIOS version but not in the new version, resulting in the POST (Power-On Self-Test) card self-test crash after upgrading to the new BIOS version. In this case, it is necessary to rely on the operation and maintenance personnel to restore the value of MMIO High Base (Memory-mapped input / output High Base) out of band or use the method of powering off the target device, opening the chassis cover, clearing CMOS (Complementary Metal Oxide Semiconductor, a piece of memory) to restore the option default value. After completing a series of operations, power on the target device again and complete the POST self-test, and finally enter the OS (Operating System) normally before use. The inconvenience of this method is: 1. If the operation and maintenance personnel set the value of MMIO High Base a long time ago and keep the configuration upgrade a long time later, downtime will occur. The operation and maintenance cannot determine the root cause of the downtime in the first time, and it takes a lot of time to locate the fault. 2. After the machine self-checks, a simple restart or power failure cannot restore to normal. It is necessary to modify the MMIO High Base option out of band or open the chassis to clear CMOS to restore the default value. The out-of-band manual modification or opening the cover to clear CMOS is a single operation, which greatly reduces the operation and maintenance efficiency.

[0003] It can be seen that how to efficiently handle downtime caused by version iteration is a problem that technical personnel in this field need to solve. Summary of the invention

[0018] Creating a query instruction carrying relevant information of a target configuration item through a basic input and output system, and sending the query instruction to a preset storage space;

[0019] The target default value corresponding to the target configuration item is returned after the preset storage space responds to the query instruction through the basic input and output system.

[0020] Optionally, the target configuration items in the upgraded firmware are tested to determine the corresponding reasons for the downtime, including:

[0021] Initiate a fault detection mechanism to analyze a target configuration item in the upgraded firmware to determine whether a first configuration item value of the target configuration item is within a preset threshold range;

[0022] If the value of the first configuration item is not within the preset threshold range, it is determined that the cause of the downtime is that there is an abnormal value setting of the target configuration item.

[0023] Optionally, the method of the present application further includes:

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0048] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] like Figure 1 As shown, the embodiment of the present application discloses a device firmware repair method, including:

[0050] Step S11, when the target device is powered on, a system self-check operation is triggered through the basic input and output system to obtain a corresponding self-check result; the current firmware of the basic input and output system is the upgraded firmware.

[0051] In an embodiment of the present application, the configuration item values ​​of the firmware of the basic input / output system (BIOS) of the target device may change before and after the upgrade; the change of the BIOS configuration item values ​​may cause the device to malfunction, such as a startup crash; therefore, when the device is powered on after the BIOS firmware is upgraded, a system self-test operation can be triggered to obtain corresponding self-test results; the system self-test mainly detects whether the upgraded firmware of the BIOS is compatible with the device.

[0052] In a specific embodiment, before triggering the system self-check operation through the basic input and output system, the method may further include: obtaining and executing a firmware upgrade command for the basic input and output system of the target device to perform a firmware upgrade operation on the basic input and output system of the target device; during the firmware upgrade operation of the basic input and output system, triggering a preset configuration item value saving operation to retain the default values ​​of the relevant configuration items of the firmware before the upgrade of the basic input and output system; correspondingly, repairing the first configuration item value of the target configuration item in the upgraded firmware through the basic input and output system to repair the first configuration item value of the upgraded firmware to the target default value, so as to start the target device based on the repaired firmware, including: querying the target default value corresponding to the target configuration item from the default values ​​of the relevant configuration items through the basic input and output system; triggering a repair operation on the first configuration item value of the target configuration item in the upgraded firmware through the basic input and output system and using the target default value to repair the first configuration item value of the upgraded firmware to the target default value, and obtaining the corresponding repaired firmware, so as to start the target device based on the repaired firmware. Specifically, the process of upgrading the firmware of the basic input-output system of the device should be completed in advance, and the corresponding firmware upgrade operation should be performed based on the firmware upgrade command for the basic input-output system firmware of the target device; and, during the firmware upgrade process, the default values ​​of several configuration items corresponding to the firmware before the upgrade need to be retained. Furthermore, when the firmware is repaired later, the basic input-output system can be used to query the target default value corresponding to the target configuration item from the pre-saved default values ​​of the relevant configuration items of the firmware before the upgrade; then the target default value can be used to trigger the repair operation of the first configuration item value of the target configuration item in the upgraded firmware; specifically, the first configuration item value is modified to the target default value of the firmware before the upgrade corresponding to the target configuration item, and the upgraded firmware is obtained after the configuration item value is modified; the repaired firmware can be used to restart the target device later.

[0053] In a specific embodiment, triggering a preset configuration item value saving operation to retain the default values ​​of the configuration items of the firmware before the basic input and output system upgrade may include: triggering the preset configuration item value saving operation to save the default values ​​of the configuration items of the firmware before the basic input and output system upgrade to a preset storage space; correspondingly, querying the target default value corresponding to the target configuration item from the default values ​​of the relevant configuration items through the basic input and output system, may include: creating a query instruction carrying the relevant information of the target configuration item through the basic input and output system, and sending the query instruction to the preset storage space; obtaining the target default value corresponding to the target configuration item returned by the preset storage space after the basic input and output system responds to the query instruction. Specifically, the process of saving the default values ​​of several configuration items of the firmware before the basic input and output system upgrade is firstly to trigger the preset configuration item value saving operation, and based on the operation, save the default values ​​of the configuration items of the firmware before the basic input and output system upgrade to the pre-prepared storage space. It can be understood that in the subsequent query process of the target default value corresponding to the target configuration item, a query instruction carrying relevant information of the target configuration item can be created through the basic input and output system, and based on the query instruction, the target default value corresponding to the target configuration item can be queried from the default values ​​of each configuration item of the firmware before the upgrade saved in the preset storage space; the target default value is the configuration item value corresponding to the target configuration item in the firmware before the upgrade.

[0054] Step S12: If the self-test result indicates that the target device crashes at the target location during the startup process, the target configuration item in the upgraded firmware is tested to determine the corresponding crash cause; wherein the target configuration item is the high base address of the memory mapped input and output.

[0055] Furthermore, the above steps can be used to perform a system self-test on the device to obtain the corresponding self-test results; it is understandable that if there is no problem with the self-test, the device can directly enter the operating system normally and complete the startup. When the self-test result indicates that the target device crashes at the target position point during the startup process, where the target position point refers to the position 0x31, it is necessary to detect the target configuration items in the upgraded firmware to determine the cause of the crash based on the test results; it is understandable that when the system crashes at the position 0x31, it is necessary to detect the high base address (MMIO High Base) of the memory mapped input and output to determine whether the crash is caused by an unreasonable setting of the value of MMIO High Base.

[0056] In a specific embodiment, detecting the target configuration item in the upgraded firmware to determine the corresponding cause of downtime may include: starting a fault detection mechanism to analyze the target configuration item in the upgraded firmware to determine whether the first configuration item value of the target configuration item is within a preset threshold range; if the first configuration item value is not within the preset threshold range, then determining that the cause of downtime is that the target configuration item has a numerical setting abnormality. Specifically, in the process of detecting the target configuration item to determine the cause of downtime, the fault detection mechanism may be started to analyze the first configuration item value of the target configuration item in the upgraded firmware to determine whether the first configuration item value is within a preset threshold range, which is a threshold range of configuration item values ​​for the target configuration item that is pre-set so that the device can normally boot into the operating system; if the first configuration item value of the target configuration item in the upgraded firmware is not within the preset threshold range, then it means that the first configuration item value is abnormal, and it can be determined that the cause of the current device downtime is that the target configuration item has a numerical setting abnormality.

[0057] Step S13: If the cause of the downtime is that there is an abnormal value setting of the target configuration item, the first configuration item value of the target configuration item in the upgraded firmware is repaired through the basic input and output system to repair the first configuration item value of the upgraded firmware to the target default value, so as to start the target device based on the repaired firmware; the target default value is the second configuration item value of the target configuration item of the pre-upgrade firmware corresponding to the upgraded firmware.

[0058] In the embodiment of the present application, the above steps can be used to determine the reason why the target device crashes during the startup process; if the target device crashes because the target configuration item of the upgraded firmware has an abnormal value setting, it is necessary to repair the first configuration item value of the target configuration item with the abnormality. Further, the first configuration item value of the target configuration item is repaired, specifically replacing the first configuration item value with a target default value that meets the startup requirements; the target default value can be queried from the configuration item information corresponding to the firmware before the upgrade, and the second configuration item value corresponding to the target configuration item can be queried from the several configuration item values ​​corresponding to the firmware before the upgrade; then the second configuration item value is used as the target default value to repair the first configuration item value of the upgraded firmware.

[0059] In a specific embodiment, it may also include: configuring a watchdog for monitoring the system status in the target device; accordingly, before starting the target device based on the repaired firmware, it also includes: after repairing the first configuration item value of the upgraded firmware to the target default value, triggering a restart operation through a preset watchdog to restart the target device based on the repaired firmware. Specifically, a watchdog for monitoring the system status may be configured in advance in the target device, and the watchdog may be triggered based on a freely set fault recovery time. Furthermore, after replacing and repairing the first configuration item value of the upgraded firmware with the second configuration item value of the pre-upgraded firmware, a restart operation may be triggered through a preset watchdog, the basic input and output system may be restarted, and the system self-check operation may be restarted to start the target device into the corresponding operating system.

[0060] In another specific embodiment, the process of repairing the first configuration item value of the target configuration item in the upgraded firmware through the basic input and output system to repair the first configuration item value of the upgraded firmware to the target default value can also include: recording the modification operation information corresponding to the repair of the first configuration item value of the target configuration item by the basic input and output system; sending the modification operation information to the preset terminal so that the modification operation information can be viewed through the preset terminal. Specifically, in the process of starting the target device and repairing the first configuration item value of the target configuration item in the upgraded firmware through the basic input and output system, the relevant modification operation information can be recorded, and the recorded modification operation information can be sent to the preset terminal so that relevant personnel can understand the device startup and configuration item value repair process through the preset terminal.

[0061] In another specific embodiment, the process of starting the target device based on the repaired firmware may also include: if the target device is in a downtime state again, the basic input and output system is used to repair the values ​​of several configuration items corresponding to the repaired firmware that meet the preset downtime conditions to the default configuration item values ​​corresponding to the relevant pre-upgrade firmware, so as to start the target device based on the repaired firmware. Specifically, if the target device is in a downtime state again during the subsequent startup process after the target device repairs the values ​​of the target configuration items through the above steps, it means that there are still configuration items with abnormal values ​​in the repaired firmware. At this time, the basic input and output system can be used to repair the values ​​of several configuration items in the repaired firmware that meet the preset downtime conditions (cause of the downtime failure) to the default configuration item values ​​of the relevant configuration items of the pre-upgrade firmware, and then the repaired firmware is used to restart the target device to successfully complete the system self-check and enter the corresponding operating system. It is understandable that after repairing the first configuration item value of the target configuration item of the upgraded firmware of the target device, if the shutdown failure still occurs when restarting, the relevant configuration items in the upgraded firmware can be modified in sequence through the pre-set mapping relationship between the shutdown failure and the configuration item, and the device can be restarted after each modification to try to boot into the operating system. In this way, the modification of each configuration item in the upgraded firmware can be minimized while satisfying the normal startup, and the user experience of the device can be avoided as much as possible due to the modification of the configuration item.

[0062] It can be seen that the present application can, through the basic input and output system, promptly locate the configuration options that cause the downtime when a downtime occurs after a firmware upgrade; and use the pre-reserved default values ​​of the relevant configuration items of the pre-upgrade firmware to repair the upgraded firmware, so as to quickly handle the downtime caused by the firmware upgrade; when the device faces such downtime problems, it can automatically restore the default values ​​without fault location or manual restoration of the default values, and restart and power on normally; the entire process does not require human intervention, which reduces the difficulty of operation, reduces the possibility of human operational errors, and can improve the stability and reliability of the system.

[0063] like Figure 2 As shown, the embodiment of the present application discloses a device firmware repair method, which specifically includes:

[0064] In the embodiment of the present application, after the BIOS firmware is upgraded, the device will retain the configuration item related information of the original BIOS firmware before the upgrade; after that, the device is powered on and starts, and runs POST. There may be two situations in which the machine is powered on and started normally, or it crashes during the boot process. Further, if the power is on normally and the boot is completed, the operating system is entered normally; if the boot process crashes, check whether the device crashes at position 0x31; if the device card self-check crashes at position 0x31, it is judged that the device failed to boot due to the MMIO value being too large, and the BIOS can send a command to set the MMIO option to restore the default value (the default value can be 4T). After restoring the default value, the BIOS can automatically restart after the watchdog of the corresponding time is triggered through the pre-set watchdog (corresponding to FRB time, i.e. Fault Recovery Boot time, which refers to the time required for the system to recover from a fault when a fault occurs.). During the restart process, the BIOS restarts the POST process. At this time, since the MMIO value has been restored to the default value, the post can be completed smoothly, and the machine enters the OS (operating system) normally. It should be noted that while executing the above steps, the relevant modification operation information can be recorded and presented on the web management interface for the administrator to view. It is understandable that the operation and maintenance personnel need to retain the relevant information of each configuration item before the BIOS firmware upgrade in advance. Due to the uncertainty in the upgrade process or the compatibility problem between the new version of BIOS and the hardware, the device may crash at a specific location (such as 0x31). After the crash, the BIOS immediately starts the fault detection mechanism and determines the specific cause of the crash by analyzing the log information, error code, etc. during the POST process. According to the fault detection results, the BIOS locates the specific configuration option MMIO High Base that causes the problem. For example, the crash fault is caused by the value of MMIO High Base being set to the maximum value of 56T. At this time, the BIOS can restore the value of MMIO High Base of the upgraded firmware of the device to the factory default value of 4T or other values ​​through the relevant configuration item information of the firmware before the upgrade saved in advance, and send the setting action to the BMC to record it on the WEB side to prompt the user that the value of MMIO High Base has changed. After MMIO High Base is restored to the default value, the machine automatically restarts as the watchdog triggers. The machine can pass the self-test normally and enter setup or OS normally after POST is completed for user use.

[0065] It can be seen that during the device startup POST process, if the device crashes at a specific position (such as position 0x31), the BIOS can detect and repair the fault by itself, and restore the relevant configuration options to the default values ​​before the upgrade. It can quickly handle the crash caused by the firmware upgrade. The entire process does not require human intervention, which reduces the difficulty of operation, reduces the possibility of human operation errors, and can improve the stability and reliability of the system.

[0066] like Figure 3 As shown, the embodiment of the present application discloses a device firmware repairing apparatus, comprising:

[0067] The self-check module 11 is used to trigger a system self-check operation through a basic input and output system when the target device is powered on, and obtain a corresponding self-check result; the current firmware of the basic input and output system is the upgraded firmware;

[0068] The judgment module 12 is used to detect the target configuration item in the upgraded firmware to determine the corresponding cause of the downtime when the self-test result indicates that the target device has crashed at the target position point during the startup process; wherein the target configuration item is the high base address of the memory mapped input and output;

[0070] It can be seen that the present application can, through the basic input and output system, promptly locate the configuration options that cause the downtime when a downtime occurs after a firmware upgrade; and use the pre-reserved default values ​​of the relevant configuration items of the pre-upgrade firmware to repair the upgraded firmware, so as to quickly handle the downtime caused by the firmware upgrade.
