Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a method, system, apparatus, and medium for preventing BMC restart during a restart test. Background Technology

[0002] AMD servers are highly favored by customers and consumers in the market due to their superior performance and excellent price-performance ratio. Servers currently using the ROME series CPU architecture are particularly popular for their high-speed processing capabilities. Servers, as the fundamental carriers of information systems, play a crucial role, especially in the massive storage of information. To ensure stable server operation, real-time monitoring of critical server hardware and its usage is necessary, a task typically accomplished using a Hardware Monitoring and Control System (BMC). Therefore, the BMC plays a vital role in monitoring and using critical hardware, making it especially important for developers to ensure the stable operation of the hardware monitoring firmware (BMC).

[0003] However, during current system stability testing, continuous system restarts are required, and BMC restarts frequently occur during this process. A BMC restart can lead to the loss of customer hardware monitoring data. If the server malfunctions at this time, abnormal hardware cannot be quickly located or diagnosed, posing an irreparable risk to the customer's usage.

[0004] In addition, during the continuous restart testing process, the BIOS will also continuously synchronize important hardware or configuration information to the BMC. This will cause the BMC to receive information constantly. If the BIOS or server system crashes, it may also cause the BMC to restart, thereby losing the monitoring of important hardware. Summary of the Invention

[0005] To address the above issues, the present invention aims to provide a method, system, device, and medium for preventing BMC restarts during restart testing. By setting up an efficient prevention and protection mechanism for the BMC, it ensures that the AMD server maintains a highly efficient and stable BMC operation state when operating under extreme conditions.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] In a first aspect, the present invention discloses a method for avoiding BMC restart during a restart test, comprising: powering on the AMD server and initiating a restart test under the current system;

[0008] Check if there are any BMC-related anomalies in the current system;

[0009] If abnormal information is found, the potential signal used to control the BMC restart is pulled as the first reference information, and the system restart information is obtained through CPLD as the second reference information. By comparing the first reference information and the second reference information, it is determined whether the BMC should perform a restart operation.

[0010] Real-time monitoring of the data flow in the data pipeline between the BMC and BIOS, and control over the acquisition of the data flow according to the first control mechanism;

[0011] Monitor the in-band communication data stream of the BMC in real time and control the in-band communication data stream according to the second control mechanism.

[0012] Furthermore, checking whether there is any BMC-related abnormal information in the current system includes:

[0013] Run the main process through BMC, capture the main process, and check if any abnormal monitoring logs are generated;

[0014] Examine the potential signal that controls the BMC restart and determine whether there are any abnormal fluctuations in the voltage value of the potential signal.

[0015] Furthermore, the abnormal information related to the BMC includes:

[0016] Abnormal fluctuations were observed in the abnormal monitoring logs generated by the BMC main process and in the potential signals controlling the BMC restart.

[0017] Furthermore, determining whether the BMC should perform a restart operation by comparing the first reference information and the second reference information includes:

[0018] If both the first reference information and the second reference information are signals that control the BMC to perform a restart operation, then the BMC will perform a restart operation.

[0019] Furthermore, the first control mechanism includes:

[0020] If the acquisition time of the current data stream exceeds the time threshold, it is determined to be an acquisition anomaly and the data stream is deleted, and the next data stream is acquired.

[0021] If the acquisition time of the next data stream exceeds the time threshold, it is determined to be an acquisition anomaly and the data interaction is stopped for a preset time before the data stream acquisition operation continues.

[0022] If the number of abnormal acquisitions exceeds the alarm threshold, the data stream acquisition operation will be stopped and a prompt message will be reported.

[0023] Furthermore, the second control mechanism includes:

[0024] If the in-band communication data stream of the BMC exceeds the preset value, then the in-band communication of the BMC will be rate-limited.

[0025] If the data obtained by the BMC's in-band communication is the same twice in a row, the corresponding data will be deleted.

[0026] If the data acquired by the BMC's in-band communication is the same twenty times in a row, the data transmission speed of the BMC's in-band communication will be reduced.

[0027] Furthermore, the time threshold is twenty seconds, and the alarm threshold is ten times.

[0028] Secondly, the present invention also discloses a system for avoiding BMC restart during restart testing, comprising:

[0029] The test startup module is used to power on the AMD server and perform a restart test under the current system.

[0030] The information acquisition module is used to check whether there are any BMC-related abnormal information in the current system;

[0031] The restart determination module is used to pull the potential signal used to control the restart of BMC as the first reference information when there is abnormal information, and at the same time obtain the system restart information through CPLD as the second reference information. By comparing the first reference information and the second reference information, it is determined whether BMC should perform a restart operation.

[0032] The data transmission control module is used to monitor the data flow of the data pipeline between the BMC and BIOS in real time, and to control the acquisition operation of the data flow according to the first control mechanism.

[0033] The in-band communication control module is used to monitor the in-band communication data stream of the BMC in real time and control the in-band communication data stream according to the second control mechanism.

[0034] Thirdly, the present invention also discloses a device for preventing BMC restart during a restart test, comprising:

[0035] The memory is used to store the program that prevents the BMC from restarting during the restart test;

[0036] A processor, when executing a program to avoid BMC restart during the restart test, implements the steps of the method for avoiding BMC restart during the restart test as described in any of the above.

[0037] Fourthly, the present invention also discloses a readable storage medium storing a program for avoiding BMC restart during a restart test, wherein when the program for avoiding BMC restart during a restart test is executed by a processor, it implements the steps of the method for avoiding BMC restart during a restart test as described in any of the above claims.

[0038] Compared with existing technologies, the advantages of this invention are as follows: This invention discloses a method, system, device, and readable storage medium to prevent BMC restarts during restart testing. By improving the BMC's own anti-interference capability and making the data path for the BMC to receive abnormal information from the operating system less prone to blockage, it avoids the BMC from performing a restart operation due to data transmission anomalies. Through these two methods, corresponding protection measures are provided for the BMC during use in extreme server environments.

[0039] This invention, by setting up an efficient prevention and protection mechanism for the BMC, can ensure that AMD servers maintain a high-efficiency and stable operating state when operating in extreme environments, thus helping customers obtain a better user experience for AMD CPU platform server services.

[0040] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0045] The core of this invention is to provide a method to avoid BMC restarts during restart testing. In related technologies, during system stability testing, continuous restart testing is required, during which BMC restarts frequently occur. Once a BMC restart occurs, it can lead to the loss of customer hardware monitoring data. If the server malfunctions at this time, abnormal hardware cannot be quickly located or diagnosed, posing an irreparable risk to the customer. Furthermore, during continuous restart testing, the BIOS constantly synchronizes important hardware or configuration information to the BMC. This causes the BMC to continuously receive information; if the BIOS or server system crashes, it may also lead to a BMC restart, resulting in the loss of monitoring of critical hardware.

[0046] The method for preventing BMC restart during the restart test provided by this invention first involves powering on the AMD server and initiating a restart test under the current system. At this time, it checks for any BMC-related anomalies in the current system. If anomalies are found, the potential signal used to control the BMC restart is retrieved as the first reference information, and the system restart information is obtained through the CPLD as the second reference information. By comparing the first and second reference information, it is determined whether the BMC should perform a restart operation. Then, the data flow in the data pipeline between the BMC and BIOS is monitored in real time, and the acquisition of the data flow is controlled according to the first control mechanism; simultaneously, the in-band communication data flow of the BMC is monitored in real time, and the in-band communication data flow is controlled according to the second control mechanism. Therefore, this invention, by setting up an efficient prevention and protection mechanism for the BMC, can ensure that the AMD server maintains a highly efficient and stable BMC operation under extreme operating environments.

[0047] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] See Figure 1 As shown, this invention discloses a method for avoiding BMC restart during restart testing, comprising the following steps:

[0049] S1: Power on the AMD server and start a restart test under the current system.

[0050] First, power on the AMD server and run it. Then, after the AMD server has finished booting up, continuously perform restart tests within the operating system.

[0051] S2: Check if there are any BMC-related abnormal information in the current system.

[0052] It should be noted that the abnormal information related to BMC in this method includes two types of information: one is the abnormal monitoring log generated by the BMC main process, and the other is the abnormal fluctuation of the potential signal that controls the restart of BMC.

[0053] Specifically, first, the main process of the BMC is run, and the process is captured to check for any abnormal monitoring logs. Then, the voltage signal controlling the BMC restart is examined to determine if there are any abnormal fluctuations in its voltage value. If abnormal monitoring logs are generated or the voltage signal controlling the BMC restart shows abnormal fluctuations, it can be confirmed that there are BMC-related anomalies in the previous system.

[0054] S3: If abnormal information exists, pull the potential signal used to control the BMC restart as the first reference information, and at the same time obtain the system restart information through CPLD as the second reference information. By comparing the first reference information and the second reference information, determine whether the BMC should perform a restart operation.

[0055] Specifically, after obtaining the first reference information and the second reference information, if both the first reference information and the second reference information are signals that control the BMC to perform a restart operation, then the BMC performs a restart operation.

[0056] In a specific implementation, if abnormal information exists, the BMC retrieves the potential information of the corresponding set point. This potential information is used to control the BMC restart ground potential signal and maintain a stable operating state related to voltage and current. Based on this potential information identification, the system restart information obtained by the BMC through the CPLD also needs to be identified. That is, the contents of the two types of information are compared. Since the two types of information cannot simultaneously trigger and be determined to indicate a BMC restart operation within a certain time interval, if neither type of information is determined to indicate a BMC restart operation, then no restart operation is performed. Conversely, if both types of information are determined to indicate a BMC restart operation, then the BMC restart operation is performed. Through this mechanism, abnormal interference from system restarts on the BMC can be effectively eliminated.

[0057] S4: Monitors the data flow in the data pipeline between the BMC and BIOS in real time, and controls the acquisition operation of the data flow according to the first control mechanism.

[0058] Specifically, the system monitors the data flow in the data pipeline between the BMC and BIOS in real time. If the acquisition time of the current data flow exceeds twenty seconds, it is considered an acquisition anomaly, and the data flow is deleted before acquiring the next data flow. If the acquisition time of the next data flow exceeds twenty seconds, it is considered an acquisition anomaly, and data interaction is stopped for a preset time before resuming data flow acquisition. Furthermore, if the number of acquisition anomalies exceeds ten, the data flow acquisition operation is stopped, and a warning message is reported.

[0059] In a specific implementation, if the BIOS freezes and crashes at a certain interface, data interaction with the BMC will be stuck at a specific point. Prolonged waiting for pipeline information can create the illusion of congestion, causing the BMC to restart. To address this issue, this step adds data flow judgment to the information pipeline. It judges the acquisition time of the same data stream; if the acquisition time exceeds a set threshold (e.g., 20 seconds), it is considered abnormal, and the data is quickly deleted. Then, it continues to acquire the next series of data. If it still cannot be acquired within the specified time, an abnormality is determined, interaction is stopped, and interaction is attempted again after a period of time. When the number of acquisition attempts exceeds ten, data acquisition will cease, an abnormality is determined, and a prompt message is reported.

[0060] S5: Monitor the in-band communication data stream of BMC in real time and control the in-band communication data stream according to the second control mechanism.

[0061] Specifically, the BMC's in-band communication data stream is monitored in real time. If the BMC's in-band communication data stream exceeds a preset value, the in-band communication of the BMC is rate-limited. If the data obtained by the BMC's in-band communication is the same twice in a row, the corresponding data is deleted. If the data obtained by the BMC's in-band communication is the same twenty times in a row, the data transmission speed of the BMC's in-band communication is reduced.

[0062] In a specific implementation, server system restarts continuously impact BMC in-band communication; these constant in-band restarts can cause congestion in internal channels, as both in-band acquisition and BMC operation run on the IPMI main thread. To avoid this problem, this step first monitors the data stream used by the system to communicate with the BMC. This can be done by capturing packets over a certain period of time, then calculating the amount of captured data.

[0063] At this point, the size and frequency of in-band data exchange can be determined by comparing it with the size of a pre-defined interactive data stream.

[0064] If it can be determined that data exchange is too slow or too frequent, corresponding restrictions will be implemented, accepting only carriers of important data. Furthermore, each time data is acquired, it will be compared with the previously acquired data; if they are identical, the data will be promptly and completely deleted. If the same data appears twenty times consecutively, information will be filtered and acquired at a normal rate according to project requirements.

[0065] This embodiment provides a method to avoid BMC restarts during restart testing. By improving the BMC's own anti-interference capabilities and making the data path for the BMC to receive abnormal information from the operating system less prone to blockage, the BMC is prevented from performing a restart operation due to data transmission anomalies. These two methods provide corresponding protection measures for the BMC during extreme server environments, ensuring that AMD servers maintain efficient and stable operation under extreme usage conditions.

[0066] See Figure 2 As shown, the present invention also discloses a system for avoiding BMC restart during restart testing, comprising: a test startup module 1, an information acquisition module 2, a restart determination module 3, a data transmission control module 4, and an in-band communication control module 5.

[0067] Test startup module 1 is used to power on the AMD server and start a restart test under the current system.

[0068] In a specific implementation, test startup module 1 is specifically used to: perform a power-on and startup operation on the AMD server. After the AMD server has finished booting up, a restart test is continuously performed under the operating system.

[0069] Information acquisition module 2 is used to check whether there is any BMC-related abnormal information in the current system.

[0070] In a specific implementation, the information acquisition module 2 is specifically used to: capture the main process running through the BMC and check if any abnormal monitoring logs are generated; check the potential signal controlling the BMC restart and determine if the voltage value of the potential signal has abnormal fluctuations; if abnormal monitoring logs are generated or the potential signal controlling the BMC restart has abnormal fluctuations, it can be determined that there is BMC-related abnormal information in the current system.

[0071] The restart determination module 3 is used to pull the potential signal used to control the restart of the BMC as the first reference information when there is abnormal information, and at the same time obtain the system restart information through the CPLD as the second reference information. By comparing the first reference information and the second reference information, it is determined whether the BMC should perform a restart operation.

[0072] In a specific implementation, the restart determination module 3 is specifically used to: when abnormal information exists, pull the potential signal used to control the BMC restart as the first reference information, and simultaneously obtain the system restart information through the CPLD as the second reference information. After obtaining the first and second reference information, if both the first and second reference information are signals controlling the BMC to perform a restart operation, then the BMC performs the restart operation. Otherwise, the BMC restart operation is not performed.

[0073] The data transmission control module 4 is used to monitor the data flow of the data pipeline between the BMC and the BIOS in real time, and to control the acquisition operation of the data flow according to the first control mechanism.

[0074] In a specific implementation, the data transmission control module 4 is specifically used to: monitor the data flow of the data pipeline between the BMC and BIOS in real time; if the acquisition time of the current data flow exceeds twenty seconds, it is determined to be an acquisition anomaly, and the data flow is deleted, and the next data flow is acquired; if the acquisition time of the next data flow exceeds twenty seconds, it is determined to be an acquisition anomaly, and the data interaction is stopped for a preset time before continuing the data flow acquisition operation. If the number of acquisition anomalies exceeds ten, the data flow acquisition operation is stopped, and a prompt message is reported.

[0075] The in-band communication control module 5 is used to monitor the in-band communication data stream of the BMC in real time and control the in-band communication data stream according to the second control mechanism.

[0076] In a specific implementation, the in-band communication control module 5 is specifically used for: real-time monitoring of the in-band communication data stream of the BMC; if the traffic of the in-band communication data stream of the BMC exceeds a preset value, then performing a flow limiting operation on the in-band communication of the BMC; if the data obtained by the in-band communication of the BMC is the same twice in a row, then deleting the corresponding data; if the data obtained by the in-band communication of the BMC is the same twenty times in a row, then reducing the data transmission speed of the in-band communication of the BMC.

[0077] This embodiment provides a system that avoids BMC restart during restart testing. By setting up an efficient prevention and protection mechanism for the BMC, it can ensure that AMD servers maintain a high-efficiency and stable operating state when operating under extreme usage environments, helping AMD CPU platform server services to achieve a better user experience for customers.

Check the potential signal controlling the BMC restart and determine if the voltage value of the potential signal has abnormal fluctuations. If abnormal monitoring logs are generated or the potential signal controlling the BMC restart has abnormal fluctuations, it can be determined that there is BMC-related abnormal information in the current system.

[0089] In a specific implementation, when the processor executes the computer program stored in the memory, it can specifically implement the following steps: When abnormal information exists, it retrieves a potential signal used to control the BMC restart as first reference information, and simultaneously obtains system restart information through the CPLD as second reference information.
