Background technique

BMC (Baseboard Management Controller) is the baseboard management controller. It is the core component of the server management system defined by the IPMI (Intelligent Platform Management Interface) protocol, that is, the intelligent platform management interface. It is a system-independent management software based on industry standards. The IPMI specification is used for some operations such as remote management of servers, firmware upgrades, and system monitoring.

With the rapid development of computer technology, BMC (Baseboard Management Controller) plays an increasingly important role in monitoring and management services in servers, and its status in the server industry is getting higher and higher. Attacks against BMC firmware emerge in an endless stream, and various Such an attack would cause the BMC firmware to malfunction. Therefore, in the process of using the server, whether it is operation maintenance or R&D process, it is unavoidable to encounter the situation that the BMC cannot be started. In recent years, due to the impact of the epidemic, telecommuting has also become the norm. At this time, when the BMC firmware crashes and cannot be recovered, the traditional recovery method is to log in to the system operating system to update the system software, or use the burner to update the system software. The Flash (memory chip) is disassembled and put into a specific burner for burning. These two traditional methods are too limited, relying on the operating system and the operating system has login permissions and read and write permissions. During the operation and maintenance period, due to the consideration of system and data security, customers often do not allow the operation and maintenance to enter the operating system. It is impossible to install the programming software in the operating system, and the machine often does not have the operating system installed in the development stage. Even if the operating system is installed, the operating system may be shut down when the BMC crashes, and it cannot be remotely turned on. Remove the Flash. It is difficult for programming to meet the main tone of remote office, and it relies too much on human intervention. Or store the backup image in the BMC or the machine in advance. The backup image is not flexible enough.

Therefore, in order to make up for the inability to remotely upgrade and quickly restore the BMC firmware in the prior art, it is particularly important to provide a fast, simple and flexible method for restoring the BMC firmware.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a method for updating BMC firmware according to an embodiment of the present invention. The method can include:

S100, monitor the original BMC;

This embodiment does not limit the specific method of monitoring the original BMC, as long as the running state of the original BMC can be monitored. For example, monitor the original BMC by monitoring the running state of the BMC fed back by the Host-CPU (host central processing unit) in the host; or monitor the running state of the original BMC by monitoring the heartbeat of the original BMC, that is, monitor the original BMC through the indicator lights. When the indicator is flashing, it means that there is a heartbeat, and the original BMC is not faulty. When the indicator is on, it means that no heartbeat is detected, and the original BMC is faulty.

S101, judge whether the original BMC is faulty according to the monitoring result;

This embodiment does not limit the specific means of judging whether the original BMC is faulty according to the monitoring result, as long as it can be judged whether the original BMC is faulty according to the monitoring result. For example, if the feedback message sent by the original BMC is not received after sending the dog feeding message, the Host-CPU (host central processing unit) determines that the original BMC is faulty, and then monitors the result determined by the Host-CPU (host central processing unit). to determine whether the original BMC is faulty. Or monitor the original BMC by monitoring the status of the indicator. When the status of the monitoring indicator is that the indicator is flashing, it is determined that the original BMC is not faulty. When the status of the monitoring indicator is that the indicator is always on, it is determined that the original BMC is present. Fault; for example, when the status of the monitoring indicator is green and flashing, it is determined that the original BMC is not faulty; when the status of the monitoring indicator is green and steady on, it is determined that the original BMC is faulty, and when the status of the monitoring indicator is red When the light is on, make sure the original BMC is being flashed.

S102, when the original BMC is faulty, flush the information stored in the test BMC into the original BMC.

This embodiment does not limit the type of information stored in the test BMC, as long as it can be flashed to the original BMC. For example, the information stored in the test BMC can be the information before the original BMC fails; or no information is stored in the test BMC, at this time, the blank information is written to the original BMC, that is, the original BMC is erased through the blank test BMC. The information stored in the BMC; or the information stored in the test BMC is the information required to run the monitoring management service corresponding to the original BMC, and then flash to the blank original BMC, that is, the test BMC can be flashed in the blank original BMC Write. This embodiment also does not limit the timing of flashing the information stored in the test BMC to the original BMC. For example, when the original BMC fails, it automatically switches to the state of flashing the information stored in the test BMC to the original BMC, for example , when receiving a flash command, flash the information stored in the test BMC to the original BMC. This embodiment does not limit what operation should be performed when the original BMC is not faulty. For example, when the original BMC is not faulty, it is forbidden to perform the flashing of the information stored in the test BMC to the original BMC; or when the original BMC is not faulty, perform the original BMC remote management of the server, firmware upgrade, system monitoring Wait for some action. In this implementation, after the information stored in the test BMC is flashed into the original BMC, automatic reset of the original BMC can be realized, that is, automatic switching to the running state of the original BMC can be realized.

Based on the above implementation, the embodiment of the present invention monitors the original BMC; determines whether the original BMC is faulty according to the monitoring result; when the original BMC fails, flashes the information stored in the test BMC to the original BMC . Since the embodiment of the present invention is compared with the technical solution in the prior art in which the Flash needs to be disassembled through a burner and placed in a specific burner for burning, this embodiment only monitors the original BMC, and when it is found that the original BMC is faulty , flash the storage information in the test BMC to the original BMC, so that the original BMC can return to the normal state as soon as possible. It can be seen that the technical solutions provided by the embodiments of the present invention can quickly restore the damaged original BMC firmware in a timely manner without manual intervention.

Based on the above-mentioned embodiment, in order to further facilitate the subsequent analysis of the reason for the failure of the original BMC firmware, when the original BMC fails, it may also include:

The storage information of the original BMC is read and stored.

This embodiment does not limit the location where the storage information of the original BMC is read and stored, as long as the storage information of the original BMC can be read and stored.

This embodiment reads and stores the storage information of the original BMC when the original BMC fails, in order to facilitate the follow-up. The reason for the failure of the original BMC is analyzed, and this embodiment can facilitate problem analysis and location, and facilitate development, operation and maintenance, so as to avoid such failures in the original BMC as much as possible.

Based on the above embodiment, in order to further improve the success rate of flashing, after the information stored in the test BMC is flashed to the original BMC, it may further include:

Get the duration after flashing is completed;

When the duration exceeds a preset time threshold, and the original BMC after flashing cannot operate normally;

The step of flashing the information stored in the test BMC into the original BMC is performed again.

In this embodiment, the duration after the flashing is completed refers to the duration after the information stored in the test BMC is completely flashed to the original BMC. This embodiment does not limit the specific value of the preset time threshold, which may be limited according to the time required for restarting the original BMC. For example, it can be 4 minutes, 5 minutes, 6 minutes, 7 minutes, etc. This embodiment does not limit the specific timing for judging the original BMC running state after flashing after the preset time threshold. For example, if it is found that the original BMC after the flashing cannot run normally 5 minutes after the flashing is completed, you need to continue to perform the steps of flashing the information stored in the test BMC to the original BMC; or if the flashing is found 4 minutes after the flashing is completed If the original BMC cannot run normally, it is necessary to continue to perform the steps of flashing the information stored in the test BMC to the original BMC; or when the reset signal is received after the flashing is completed, after the flashing is detected after a preset time threshold Whether the original BMC of the test BMC can run normally, if it cannot run normally, it means that the flashing is unsuccessful, and you need to perform the steps of flashing the information stored in the test BMC to the original BMC again; or when the flashing is completed, it will automatically reset, and then in Check whether the original BMC after flashing can run normally within the preset time threshold. If it cannot run normally, it means that the flashing is unsuccessful, and you need to perform the steps of flashing the information stored in the test BMC to the original BMC again. This embodiment does not limit the operations that need to be performed after the original BMC after flashing and writing can run normally when the preset time threshold is exceeded. For example, when the flashed original BMC can run normally after the preset time threshold is exceeded, a prompt message is sent to remind the user that the flashed original BMC can be used normally, or no information is sent and the original BMC is directly executed without failure. Perform the appropriate action.

Based on the above embodiment, in order to prevent the original BMC from being unable to be restored by flashing, the flashing is always performed, which affects the efficiency of restoring the original BMC firmware. The method for updating the BMC firmware may also include:

Count the number of times that the information stored in the test BMC is written to the original BMC;

When the number of times exceeds the preset number of flashing and writing, execution of the step of flashing the information stored in the test BMC to the original BMC is suspended, and a prompt message that cannot be flashed normally is output.

This embodiment does not limit the specific value of the preset number of refreshes, for example, the preset number of times of refresh is 5 times, the number of times of preset refresh is 3 times, the number of times of preset refresh is 4 times, and the like. This embodiment also does not limit the specific type of the prompt information that cannot be written normally, for example, the prompt information that cannot be written normally can be prompted in the form of text, or the prompt information that cannot be written normally can be prompted in the form of vibration. Or the prompt information that cannot be written normally can be prompted in the form of voice.

Based on the above embodiment, in order to further facilitate monitoring of the running state of the original BMC and timely discovery of faults, the monitoring of the original BMC may include:

Monitor the original BMC through indicator lights;

When the indicator light flashes, the original BMC is not faulty;

When the indicator light is always on, the original BMC is faulty.

This embodiment does not limit the specific type of the indicator light. For example, when the green light is flashing, it means that the original BMC is not faulty, and when the green light is always on, it means that the original BMC is faulty. Or when the red light is flashing, it means that the original BMC is not faulty, and when the red light is always on, it means that the original BMC is faulty.

Based on the above embodiment, further in order to speed up the rate at which the original BMC is updated by the recruiting test BMC, before the monitoring of the original BMC, it may further include:

When receiving the read instruction, read the original BMC;

Flash the content in the original BMC into the test BMC.

In this embodiment, the specific content to be flashed into the test BMC is not limited, and the user can flash the content of the original BMC to the test BMC according to his own needs.

Based on the above-mentioned embodiment, in order to find out a problem with the original BMC firmware in time and quickly, the monitoring of the original BMC may include:

The raw BMC is monitored on a preset cycle.

This embodiment does not limit the specific time of the preset period. For example, 1 second, 2 seconds, 3 seconds, etc.

To sum up, based on the above embodiments, the BMC firmware update method provided by the embodiments of the present invention can quickly and flexibly update the BMC firmware without manual intervention. In addition, this embodiment provides a method for updating your BMC firmware. When the original BMC firmware fails, the storage information of the original BMC can be read and stored, which further facilitates subsequent accurate analysis of the cause of the original BMC firmware failure; When the flashed original BMC cannot run normally after the preset time threshold is exceeded; the step of flashing the information stored in the test BMC into the original BMC is performed again. To further prevent the situation where one-time flashing may not be successful, and through multiple flashing, the success rate of flashing can be improved. Further in this embodiment, by counting the number of times that the information stored in the test BMC is written to the original BMC, when the number of times exceeds the preset number of times of brushing, the execution of the described brushing of the information stored in the test BMC is suspended. The steps in the original BMC, and output the prompt information that cannot be flashed normally. Prevention is because the failure of the original BMC cannot be solved by flashing the information stored in the test BMC, resulting in endless flashing, so the present embodiment outputs the prompt information that cannot be flashed normally; and, further this embodiment passes the indicator light. to monitor the original BMC; when the indicator light is flashing, the original BMC is not faulty; when the indicator light is always on, the original BMC is faulty. This method can quickly and simply find out that the original BMC is faulty; further, in this embodiment, when a read instruction is received, the original BMC is read; and the content in the original BMC is flashed into the test BMC. By flashing the content in the original BMC to the test BMC before using the test BMC to update the original BMC, the subsequent use of the test BMC to restore the original BMC is more accurate and faster. It can be seen that the BMC firmware update method provided by the embodiment of the present invention can be fast, simple, and flexible, and can restore the original BMC without manual intervention.
