[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on February 29, 2024, with application number 202410232080.7 and application name “A control method, device, server and medium for an indicating device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to a control method, device, server and medium of an indicating device. Background Art

[0004] Server hardware consists of a variety of boards, each of which can be plugged into various devices and displays that indicate their status. The baseboard management controller (BMC) indirectly controls these devices and their corresponding displays by reading and writing registers exposed by complex programmable logic devices (CPLDs).

[0005] As business needs increase, the CPLD's functionality may change. In this case, the board's CPLD needs to be updated to enable the new CPLD image. After the CPLD is updated, the values ​​in all CPLD register tables return to their default values, and any functions indirectly controlled by writing to the CPLD via the BMC are restored to their default states. When an indicator device is in its default state (for example, an indicator light is off), users may misjudge or be unable to determine the device's operating status based on the indicator device's status.

[0006] Therefore, after the CPLD is updated, how to keep the indicator device in the state before the CPLD is updated so that the user can accurately understand the working state of the device through the indicator device is a technical problem that needs to be solved urgently by people in this field.

[0033] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0034] The core of this application is to provide a control method, device, server and medium for an indicating device to solve the technical problem that after the CPLD is updated, the indicating device is in a default state, causing the user to misjudge or be unable to judge the working status of the device through the status of the indicating device.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The control method of the indicator device provided in the embodiment of the present application is applied to the baseboard management controller of the motherboard. Figure 1 is a flow chart of a control method of the indicator device provided in the embodiment of the present application. As shown in Figure 1, the method includes:

[0036] S10: Obtain the current secondary setting state of the indicator device corresponding to the target device;

[0037] S11: Acquire the current refresh status and the previous refresh status of the complex programmable logic device of the target board;

[0038] The refresh status includes the unrefreshed status, the refreshing status, and the refresh completed status.

[0039] S12: When it is detected that the current refresh state and the previous refresh state meet the preset requirements, it is determined that the complex programmable logic device of the target board has completed the update;

[0040] S13: When the baseboard management controller is working, the data corresponding to the current state to be set is written into the complex programmable logic device of the target board, so that the complex programmable logic device of the target board controls the state of the indication device to be the current state to be set.

[0041] Server hardware consists of various boards, such as the motherboard, fan board, power board, and input / output (IO) board. These boards are crucial components of a server and can accommodate various devices, such as the central processing unit (CPU), memory, hard drive, graphics processing unit (GPU), fan, and power supply modules. Each board also includes an indicator to indicate the device's status. These indicators typically include indicator lights and buzzers. For example, the fan board is a key component of these boards. It hosts a fan and controls its rotation, thereby reducing the server's temperature and preventing damage from overheating. The fan board also features a light-emitting diode (LED) to indicate the fan's status. The LED's on / off and color can be used to determine the fan's current status, such as whether it's plugged in, whether it's faulty, or whether its speed is too low.

[0042] A target board is a board on a server. When controlling a specific indicator device, the board connected to that indicator device is the target board. A target device is a device installed on the target board. When controlling a specific indicator device, the operating status of the target device is reflected by that indicator device. The type and number of target boards and target devices are not limited and are determined based on actual conditions. For example, in the example above, the target board is a fan board, the target device is a fan on the fan board, and the indicator device is an indicator light on the fan board.

[0043] Since the working state of the target device may change in practice, in order to enable the user to accurately understand the working state of the target device through the indicating device, the working state of the indicating device corresponding to the target device may also change as the working state of the target device changes. Therefore, in practice, the state of the indicating device corresponding to the target device may also change each time it is set. There is no limitation on the current state of the indicating device to be set, and it may be set according to user needs. However, in order for the indicating device to accurately reflect the working state of the device. In some embodiments, obtaining the current state of the indicating device corresponding to the target device to be set includes:

[0044] Get the in-place status of the target device;

[0045] In the case where it is detected that the target device is not in position, determining that the current secondary state to be set of the indicator device corresponding to the target device is the first state;

[0046] When the target device is detected to be in place, obtaining a property value of the target device; wherein the property of the target device is determined according to the type of the target device;

[0047] If it is detected that the attribute value is greater than or equal to the threshold, determining that the current state to be set of the indicator device corresponding to the target device is the second state;

[0048] If it is detected that the attribute value is less than the threshold, it is determined that the current secondary state to be set of the indicator device corresponding to the target device is the third state.

[0049] In order to obtain the in-place state and attribute value of the target device, an attribute table is established in an embodiment of the present application. The attribute table is a way of storing data and can be used for data interaction between different processes. Specifically, when obtaining the in-place state of the target device (that is, whether the device is inserted or not inserted into the board), the register for storing the in-place state data of the target device is read through the integrated circuit bus and address where the complex programmable logic device of the target board is located; the in-place state data of the target device read from the register for storing the in-place state data of the target device is stored in the attribute table; the in-place state of the target device is obtained from the attribute table.

[0050] When obtaining the attribute value of the target device, the register storing the attribute value of the target device is read through the integrated circuit bus and address of the complex programmable logic device of the target board; the attribute value of the target device read from the register storing the attribute value of the target device is stored in the attribute table; and the attribute value of the target device is obtained from the attribute table. After obtaining the attribute value, the attribute value is compared with a threshold value to determine the current state to be set for the indicator device. The threshold value is not limited and is determined based on actual conditions.

[0051] The following example illustrates the process of determining the current pending state of the fan light on the fan board. To facilitate user understanding, before explaining how to control the current pending state of the fan light on the fan board, some of the fan board's functions are explained. The fan's rotation and the status of the fan light are directly controlled by a complex programmable logic device (CPLD). CPLDs are digital integrated circuits typically used to implement various logic circuits, state machines, and timing control functions. The presence of the fan, the fan speed, and the illumination of the fan light are all directly controlled by the CPLD. The CPLD exposes a set of registers to other controllers, which can indirectly control the status of the fan and fan board by reading and writing to these registers. For example, the basic management controller can determine whether a fan is plugged in by reading specific CPLD registers and indirectly control the fan speed and the status of the fan light by writing to specific registers.

[0052] For some functions of the fan board, the complex programmable logic device and the baseboard management controller are often implemented in the following way: 1. Fan in-place status: controlled by the complex programmable logic device. The complex programmable logic device writes different values ​​to specific registers when in place and when not in place. The baseboard management controller can read the value to determine whether the fan is in place; 2. Fan speed: indirectly controlled by the baseboard management controller by writing to the complex programmable logic device. There are many devices plugged into various boards of the server. There are temperature sensors on the devices. The baseboard management controller obtains the temperature of the device by reading the values ​​of these temperature sensors, and then calculates the required pulse width modulation (Pulse Width Modulation) through a linear algorithm or a proportional-integral-derivative (PID) algorithm. Modulation (PWM) value, and then calculate the fan speed through the PWM value, and then write the speed into the specific register of the complex programmable logic device to control the fan speed; 3. Fan light: indirectly controlled by the baseboard management controller by writing to the complex programmable logic device. The baseboard management controller determines the fan's presence status by reading the complex programmable logic device. If it is not in place, the fan light is turned off by writing to the specific register of the complex programmable logic device. If it is in place, the fan speed is read. If the speed is higher than a certain speed, the fan light is turned green by writing to the specific register of the complex programmable logic device, indicating that the fan speed is normal. If it is lower than a certain speed, the fan light is turned orange by writing to the specific register of the complex programmable logic device, indicating that the fan speed is abnormal. The fan speed is determined by the temperature of each device on the server. The temperature of these devices may change continuously over time, so the baseboard management controller must write to the complex programmable logic device every second for the fan speed to ensure that the fan speed is real-time data.

[0053] Now that we've explained some of the fan board's functions, let's take the example of controlling the current pending state of the fan indicator on the fan board to explain how to determine the current pending state. This process consists of two parts: the first is obtaining the fan's status, and the second is determining the current pending state of the indicator based on the fan's status.

[0054] FIG2 is a flow chart of a method for obtaining fan status provided by an embodiment of the present application. As shown in FIG2 , the method includes:

[0055] S14: Read the fan status;

[0056] S15: Determine whether the fan is in place; if so, proceed to step S16; if not, proceed to step S17;

[0057] S16: Setting the fan speed value in the attribute table;

[0058] S17: Set the status of the fan in the attribute table to a scanning disabled state.

[0059] In implementation, in order to obtain the status of the fan, specifically, 1. the baseboard management controller reads the register related to the fan position through the integrated circuit bus and address where the complex programmable logic device of the fan board is located;

[0060] 2. Determine whether the fan is in place based on the value of the relevant register. If not, set the fan status in the attribute table to prohibit scanning;

[0061] 3. If the fan is in place, continue to read the fan speed related registers, obtain the fan speed, and store it in the attribute table.

[0062] After obtaining the fan status, the indicator light's current secondary state (LEDPattern) is determined based on the fan status. If the fan is not in place, the fan light's current secondary state is determined to be the first state, meaning the fan light is off (LEDPattern can be set to 0x00). If the fan is in place and the fan speed is greater than or equal to a threshold (for example, 500 rpm), indicating the fan is functioning normally, the fan light's current secondary state is determined to be the second state (normal state, LEDPattern can be set to 0x01, meaning green light). If the fan is in place and the fan speed is less than a threshold (for example, 500 rpm), indicating the fan is running too low, the fan light's current secondary state is determined to be the third state (abnormal state, LEDPattern can be set to 0x10, meaning orange light).

[0063] As business needs change, the functions of the complex programmable logic device may be added or changed. In this case, it is necessary to update the complex programmable logic device of the board so that the new complex programmable logic device image can take effect. However, after the complex programmable logic device is updated, the values ​​in all register lists in the complex programmable logic device will become default values, and those functions that are indirectly controlled by writing to the complex programmable logic device through the baseboard management controller will be restored to the default state, such as the fan light will be restored to the default state - off. At this time, the user will misjudge or be unable to judge the working status of the device based on the status of the indicator device. Therefore, in the embodiment of the present application, after determining that the complex programmable logic device of the target board has been updated, the complex programmable logic device is rewritten so that the indicator device maintains its original state.

[0064] Updating a CPLD involves two steps: upgrading and refreshing. The first step involves the baseboard management controller (BMC) writing the CPLD upgrade file to the CPLD via the integrated circuit bus. However, the CPLD does not take effect immediately, requiring a second step, refreshing. Refreshing involves the BMC writing a command to the CPLD via the integrated circuit bus, which enables the new CPLD upgrade file to take effect. Because refreshing the CPLD to enable the new CPLD file while the server's operating system (OS) is running can affect the functionality of the Basic Input / Output System (BIOS) and the operating system, some data that requires the BIOS to obtain the CPLD and then pass it to the BMC cannot be passed to the BMC. Furthermore, after refreshing the CPLD, the values ​​in all CPLD registers return to default values. The value of a particular register controls the motherboard's power-on state. If this default value causes the motherboard to lose power, shutting down the operating system. If the operating system is still running at this time, this can affect functionality. Therefore, refreshing the CPLD is done only after the server is shut down. In practice, the server may be in the power-on state or the power-off state. The following describes the method of updating the complex programmable logic device of the target board when the server is in the power-off state and the method of updating the complex programmable logic device of the target board when the server is in the power-on state. In some embodiments, updating the complex programmable logic device of the target board includes:

[0065] Obtain the image file of the complex programmable logic device of the upgraded target board;

[0066] Writing the upgraded image file of the complex programmable logic device of the target board into the complex programmable logic device of the target board;

[0067] Obtain the motherboard's complex programmable logic device to obtain the server's power on / off status;

[0068] When it is detected that the power-on / off state of the server is the power-off state, a refresh operation of the complex programmable logic device of the target board is executed.

[0069] In order to facilitate users to understand the update process of the complex programmable logic device, a refresh variable is set in the embodiment of the present application. Specifically, before updating the complex programmable logic device of the target board, it also includes:

[0070] Setting a refresh variable used to represent a refresh state to a first preset value and storing the value in the attribute table;

[0071] After detecting that the server is in the shutdown state, and before completing the refresh operation of the complex programmable logic device of the target board, the method further includes:

[0072] Setting the refresh variable to a second preset value and storing it in the attribute table;

[0073] After detecting that the refresh operation of the complex programmable logic device of the target board is completed, the method further includes:

[0074] The refresh variable is set to a third preset value and stored in the attribute table; wherein the first preset value, the second preset value, and the third preset value are not equal.

[0075] When it is detected that the server is in the power-on state, at least the integrated circuit bus and address of the target board's complex programmable logic device and a flag indicating that the target board's complex programmable logic device has not been refreshed are stored in the motherboard's memory, and the target board's complex programmable logic device is refreshed after a power cycle (power off, wait a few seconds, then power on). Executing the target board's complex programmable logic device refresh operation after the power cycle includes:

[0076] After the power cycle, a fourth preset value is written into a memory for storing power-on and power-off states in the complex programmable logic device of the mainboard to control the server to shut down; the fourth preset value is not limited and is determined according to actual conditions;

[0077] Reading data in the memory of the mainboard, and determining whether the data in the memory of the mainboard contains a flag indicating that the complex programmable logic device of the target board has not been refreshed;

[0078] If so, a refresh operation of the complex programmable logic device of the target board is performed according to the integrated circuit bus and address where the complex programmable logic device of the target board is located in the memory of the main board.

[0079] Similarly, in order to facilitate users to understand the update process of the complex programmable logic device, a refresh variable is set in the embodiment of the present application. Specifically, before updating the complex programmable logic device of the target board, it also includes:

[0080] Setting a refresh variable used to represent a refresh state to a first preset value and storing the value in the attribute table;

[0081] After detecting that the data in the memory of the mainboard includes a flag indicating that the complex programmable logic device of the target board has not been refreshed, and before completing the refresh operation of the complex programmable logic device of the target board according to the integrated circuit bus and address of the complex programmable logic device of the target board in the memory of the mainboard, the method further includes:

[0082] Setting the refresh variable to a second preset value and storing it in the attribute table;

[0083] In the case where a refresh operation of the complex programmable logic device of the target board is completed according to the integrated circuit bus and address where the complex programmable logic device of the target board is located in the memory of the main board, the method further includes:

[0084] The refresh variable is set to a third preset value and stored in the attribute table; wherein the first preset value, the second preset value, and the third preset value are not equal.

[0085] For the above-mentioned method of updating a complex programmable logic device when the server is in a shutdown state and the method of updating a complex programmable logic device when the server is in a powered-on state, when it is detected that the current refresh state and the previous refresh state meet preset requirements, determining that the complex programmable logic device of the target board has completed the update includes:

[0086] When it is detected that the refresh variable corresponding to the previous refresh state is the first preset value or the second preset value, and the refresh variable corresponding to the current refresh state is the third preset value, it is determined that the complex programmable logic device of the target board has completed updating.

[0087] There is no limit on the first preset value, the second preset value, and the third preset value of the refresh variable. For example, if the initial value is set to 0, it means that no refresh is being performed, 1 means that refresh is being performed, and 2 means that refresh is completed.

[0088] Since refreshing a complex programmable logic device (CPLD) requires shutting down the server, to ensure normal operation of the server after the refresh is complete, in practice, if it is detected that the data in the motherboard's memory does not contain a flag indicating that the complex programmable logic device of the target board has not been refreshed, or if a refresh operation of the complex programmable logic device of the target board is performed based on the integrated circuit bus and address of the target board's CPLD in the motherboard's memory, a fifth preset value is written to the memory used to store the power on / off status to control the server to start up. The fifth preset value is not limited and is determined based on actual conditions.

[0089] To help users further understand the update process of a complex programmable logic device, FIG3 is a flowchart of a method for updating a complex programmable logic device provided in an embodiment of the present application. As shown in FIG3 , the method includes:

[0090] S18: Set the refresh variable to 0 and set it in the attribute table;

[0091] S19: Upgrade the complex programmable logic device until the upgrade is completed;

[0092] S20: Read the power-on / off related attributes in the attribute table to determine whether the device is currently powered on; if not, proceed to step S21; if so, proceed to step S22;

[0093] S21: temporarily storing the unrefreshed flag bit and the bus address of the complex programmable logic device in the memory of the mainboard;

[0094] S22: Set the refresh variable to 1 and set it in the attribute table;

[0095] S23: executing a refresh operation of the complex programmable logic device;

[0096] S24: Set the refresh variable to 2 and set it in the attribute table.

[0097] In practice, updating a complex programmable logic device includes the following process:

[0098] 1. Before updating the complex programmable logic device, set the refresh variable to 0, indicating that it is not in the refresh phase, and set it in the attribute table;

[0099] 2. When upgrading the CPLD image file through scripts, web interfaces, or Redfish, the baseboard management controller will split the image file into fixed-size pieces and write them to the CPLD on the fan board through the integrated circuit bus. At this point, the new CPLD image is not yet effective and requires a second refresh operation to take effect.

[0100] 3. Read the power-on / off related properties in the property table to determine whether the device is currently powered on or off. If it is powered off, the complex programmable logic device refresh operation can be performed at this time, and step 4 can be executed. Otherwise, step 5 can be executed.

[0101] 4. If the system is shutting down, first set the refresh variable to 1 and then write it to the property table, indicating that the CPLD is being refreshed. Then the baseboard management controller refreshes the CPLD by writing preset values ​​to specific registers of the CPLD. After the refresh, the new CPLD image takes effect. Then set the refresh variable to 2 and set it to the property table, indicating that the refresh is complete.

[0102] 5. If the computer is powered on, the complex programmable logic device refresh operation cannot be performed at this time. First, temporarily store relevant information such as the unrefreshed flag, the integrated circuit bus where the fan board is located, the address, and other related information in the mainboard's electrically erasable programmable read-only memory (EEPROM), and then perform the refresh operation when the power is cycled.

[0103] FIG4 is a flow chart of a method for performing a refresh of a complex programmable logic device during a power cycle according to an embodiment of the present application. As shown in FIG4 , the method includes:

[0104] S25: The user executes a power cycle instruction;

[0105] S26: Shut down the system by writing to a specific register of the motherboard's complex programmable logic device;

[0106] S27: After the shutdown is successful, read the data in the mainboard memory;

[0107] S28: Determine whether there is a power-on flag; if so, proceed to step S29; if not, proceed to step S32;

[0108] S29: Set the refresh variable to 1 and set it in the attribute table;

[0109] S30: executing a complex programmable logic device refresh operation;

[0110] S31: Set the refresh variable to 2 and set it in the attribute table;

[0111] S32: Start the system by writing to specific registers of the motherboard's complex programmable logic device.

[0112] In implementation, the method for performing a refresh of a complex programmable logic device during a power cycle specifically includes the following steps:

[0113] 1. When the user performs a power cycle through commands or the web interface, the baseboard management controller will first indirectly control the server shutdown by writing a specific value to a specific register in the motherboard complex programmable logic device;

[0114] 2. After the server is shut down, the CPLD refresh operation can be performed. First, the data in the mainboard's electrically erasable programmable read-only memory is read to determine whether there is an unrefreshed flag in the electrically erasable programmable read-only memory. If not, it indicates that the CPLD update operation was not performed when the server was turned on. In this case, the server can be turned on directly by writing to the specific register of the CPLD.

[0115] 3. If there is an unrefreshed flag, it means that the server update operation was performed while the server was turned on. Then read the integrated circuit bus, address and other information where the fan board is located from the mainboard's electrically erasable programmable read-only memory. First, set the refresh variable to 1 and set it in the attribute table. Then refresh the complex programmable logic device, then set the refresh variable to 2 and set it in the attribute table, and finally turn on the server.

[0116] In order to determine whether the complex programmable logic device of the target board has completed the update, in an embodiment of the present application, the current refresh state of the complex programmable logic device of the target board and the refresh state of the previous refresh state are obtained. When it is detected that the current refresh state and the previous refresh state meet the preset requirements, it is determined that the complex programmable logic device of the target board has completed the update. There is no limitation on the preset requirements, and the determination is based on the actual situation. As described above, if the refresh variable corresponding to the current refresh state is 2, and the refresh variable corresponding to the previous refresh state is 0 or 1, then it is determined that the complex programmable logic device of the target board has completed the update.

[0117] In implementation, after it is determined that the complex programmable logic device has completed updating, the complex programmable logic device may be written in the following manner.

[0118] Method 1: After updating the CPLD, restart the baseboard management controller. The baseboard management controller will rewrite the CPLD after restarting, and the indicator device will maintain its original status.

[0119] Method 2: Regardless of whether the complex programmable logic device is updated, the complex programmable logic device is written once every second. In this way, even after the complex programmable logic device is updated, the original state of the indicating device can be maintained.

[0120] However, in method one, the baseboard management controller needs to be restarted. If the baseboard management controller is processing other business operations, the function of the baseboard management controller will be affected. This method makes the complex programmable logic device and the baseboard management controller too tightly coupled, which does not conform to the principle of high cohesion and low coupling.

[0121] In method 2, since the complex programmable logic device is written once every second, the resources of the central processing unit and memory will be greatly wasted, resulting in high CPU occupancy and high memory usage. In addition, the baseboard management controller controls the status of the fan light by writing the complex programmable logic device through the integrated circuit bus. This is an operation of software controlling hardware. If the integrated circuit bus is hung, the process of the baseboard management controller writing the complex programmable logic device through the integrated circuit bus may take a long time to complete. If it is written once every second, it will take a long time to complete each time, which may affect other functions of the software system.

[0122] Therefore, in order to solve the problem of the impact on the baseboard management controller business caused by restarting the baseboard management controller after refreshing the complex programmable logic device, and to reduce the number of times the complex programmable logic device is written, thereby avoiding the waste of central processing unit resources and memory resources, in the embodiment of the present application, after determining that the complex programmable logic device has completed the update, when the baseboard management controller is working, the data corresponding to the current secondary state to be set is written into the complex programmable logic device of the target board, so that the state of the indicator device is controlled by the complex programmable logic device of the target board to be the current secondary state to be set.

[0123] In the method provided by the embodiment of the present application, first, after determining that the complex programmable logic device of the target board has completed the update, the baseboard management controller writes the data corresponding to the current state to be set into the complex programmable logic device of the target board, so that after the complex programmable logic device is updated, the indicator device can still maintain the state to be set before the complex programmable logic device is updated, rather than the default state, so that the indicator device can accurately reflect the working state of the device, and the user can accurately understand the working state of the device through the indicator device; secondly, since the baseboard management controller is working, the baseboard management controller writes the data corresponding to the current state to be set into the complex programmable logic device of the target board, compared with the method of restarting the baseboard management controller to write the complex programmable logic device, the method provided by the present application ensures that the baseboard management controller is up to date. and other services on the processing controller; thirdly, compared with the method of writing to the complex programmable logic device every second regardless of whether the complex programmable logic device is updated, the method provided in the present application only writes to the complex programmable logic device after determining that the complex programmable logic device has completed the update, thereby reducing the number of times the complex programmable logic device is written, avoiding the waste of central processing unit resources and memory resources, and also avoiding the possible impact on software performance caused by hardware failures such as integrated circuit bus lines, thereby improving the user experience when using the server; in addition, in the method, by detecting that the current refresh status and the previous refresh status meet the preset requirements, it is determined that the complex programmable logic device of the target board has completed the update, thereby achieving accurate judgment on the completion of the update of the complex programmable logic device, making the timing of writing the complex programmable logic device more accurate.

[0124] In practice, the working state of a device usually remains unchanged over a period of time. If the working state of the indicator device is updated by writing to the complex programmable logic device every second, it will lead to a waste of CPU resources and memory resources. Therefore, in order to reduce resource waste, in some embodiments, after writing the data corresponding to the current secondary state to be set to the complex programmable logic device of the target board, the method further includes: returning to the step of obtaining the current secondary state to be set of the indicator device corresponding to the target device to obtain a new current secondary state to be set;

[0125] Determine whether the current secondary waiting setting state is the same as the new current secondary waiting setting state;

[0126] If so, the data corresponding to the current state to be set in the complex programmable logic device of the target board is kept unchanged;

[0127] If not, the data corresponding to the new current secondary state to be set will be written into the complex programmable logic device of the target board so that the state of the indicator device can be updated from the current secondary state to be set to the new current secondary state to be set through the complex programmable logic device of the target board.

[0128] Here, we continue to use the fan light as an example to illustrate its current pending state. Relative to the new current secondary pending state (represented by LEDPattern), the previous current secondary pending state is the previously set state (represented by PreLEDPattern). If PreLEDPattern and LEDPattern are different, this indicates a change in the fan state, requiring the fan light's state to be updated. Specifically, data representing the new current secondary pending state is written to the target board's complex programmable logic device (CPLD), thereby controlling the target board's CPLD to update the indicator's state from the current secondary pending state to the new current secondary pending state.

[0129] In the method provided in this embodiment, the complex programmable logic device is written only when it is detected that the current state to be set is different from the new state to be set. Compared with the method of updating the working status of the indicating device by writing the complex programmable logic device every second, the method provided in this embodiment reduces the waste of resources.

[0130] There are multiple devices on the server, and the working status of the multiple devices may need to be displayed through the status of the corresponding indicator devices. In order to ensure that the working status of each device is reflected through the corresponding indicator device as much as possible, in some embodiments, before obtaining the current state to be set of the indicator device corresponding to the target device, the following is also included:

[0131] Acquire information of all target devices and store the information of the target devices in an attribute table; wherein the information of the target devices at least includes the quantity of all target devices and an identifier of each target device;

[0132] Obtaining the current secondary setting state of the indicator device corresponding to the target device includes:

[0133] The current secondary setting state of the indicator device corresponding to each target device is obtained from the attribute table respectively.

[0134] All devices are recorded in the attribute table, and the steps of the above-mentioned control method of the indicating device are executed for each device, so that after the complex programmable logic device is updated, the indicating device corresponding to each device can still correctly reflect the working status of the device, thereby improving the user experience when using the server.

[0135] In order to enable those skilled in the art to better understand the present application, the following uses the control process of a fan light as an example, and further describes the present application in detail in conjunction with the accompanying drawings and specific implementation methods. The specific lighting process is divided into the following modules: 1. Fan status acquisition module; 2. Complex programmable logic device update module; 3. Power cycle refresh module; 4. Lighting module. The control process of the fan status acquisition module (refer to FIG2 ), the control process of the complex programmable logic device update module (refer to FIG3 ), and the control process of the power cycle refresh module (refer to FIG4 ) have been described in detail above and will not be repeated here. Only the control process of the lighting module will be described.

[0136] FIG5 is a flow chart of a method for controlling a lighting module according to an embodiment of the present application. As shown in FIG5 , the method includes:

[0137] S33: Get the number of fans;

[0138] S34: traverse all fans;

[0139] S35: Obtain the fan value and status in the attribute table, and obtain the status and speed of each fan;

[0140] S36: Determine whether the fan status is scanning prohibited; if so, proceed to step S37; if not, proceed to step S38;

[0141] S37: Set the fan light's current state to 0x00;

[0142] S38: Determine whether the fan speed is less than a threshold; if so, proceed to step S39; if not, proceed to step S40;

[0143] S39: Set the fan light's current state to 0x10;

[0144] S40: Set the fan light's current state to 0x01;

[0145] S41: Determine whether the state set last time is different from the state that should be set currently or determine whether the variable refreshed last time is 0 or 1, and whether the variable refreshed currently is 2; if so, proceed to step S42;

[0146] S42: Write to the specific register of the complex programmable logic device to set the fan light on and off and color;

[0147] S43: Assign the value of the state that should be set currently to the state set last time, assign the value of the currently refreshed variable to the value of the last refreshed variable, and return to step S35.

[0148] It should be noted that, for step S41, if no, the value of the specific register of the complex programmable logic device remains unchanged.

[0149] In practice, the control method of the lighting module specifically includes the following process:

[0150] 1. Obtain the number of fans that should be on the current server by reading the attribute table, and then iterate over each fan and perform subsequent operations on each fan;

[0151] 2. Read the speed and status of each fan from the attribute table to determine whether the fan status is "disable scanning". If it is, it means that the fan is not currently plugged in. Then, set the fan light's current status LEDPattern to 0x00, which is off.

[0152] 3. If the fan status is not in the "Disable Scan" state, it indicates that the fan is plugged in. Continue to determine whether the fan speed is less than a certain threshold, such as 500 rpm. If it is, the fan speed is too low and a fault may have occurred. Set the fan light's current status LEDPattern to 0x10, which indicates an orange light.

[0153] 4. If the fan speed is not lower than the threshold, it indicates that it is normal. Set the fan light's current status LEDPattern to 0x01, which is a green light.

[0154] 5. Determine whether "PreLEDPattern (indicates the last fan light setting state, the default value is 0xff) and LEDPattern (indicates the current fan light setting state, 0x00 is off, 0x01 is green light, 0x10 is orange light, and 0xff is the default value when the baseboard management controller starts) are different" or "PreRefresh (indicates the last CPLD refresh state) is 0 or 1 and refresh (indicates the current CPLD refresh state) is 2." If the PreLEDPattern value is different from the LEDPattern value, it means that the fan state has changed and the fan light state needs to be updated. If PreRefresh is 0 or 1 and refresh is 2, it means that the CPLD has just been refreshed and the fan light has returned to the default state - off. The fan light state needs to be updated again.

[0155] 6. The baseboard management controller writes the value of LEDPattern to the specific register of the fan board complex programmable logic device, and the complex programmable logic device controls the on and off of the fan light;

[0156] 7. Finally, assign the value of LEDPattern to PreLEDPattern and the value of refresh to PreRefresh, and continue the next loop.

[0157] Furthermore, Figure 6 illustrates an architecture for maintaining fan light status after updating a fan board's complex programmable logic device (CPLD), as provided by an embodiment of the present application. As shown in Figure 6, the architecture includes fan board 1 and mainboard 2, which exchange data to maintain fan light status after updating the fan board's CPLD. The arrows in Figure 6 are based on the fan status acquisition module, CPLD update module, power cycle refresh module, and light-on module. Data flowing into these four modules represents a read, while data flowing out represents a write.

[0158] The method for maintaining the fan light status after updating the fan board complex programmable logic device through the above architecture specifically includes the following process:

[0159] 1. The fan status acquisition module reads the fan status from the fan board complex programmable logic device register list;

[0160] 2. The fan status acquisition module reads the fan speed from the fan board complex programmable logic device register list;

[0161] 3. The fan status acquisition module writes the fan status and speed to the baseboard management controller attribute table;

[0162] 4. The complex programmable logic device update module upgrades the complex programmable logic device image to the complex programmable logic device on the fan board;

[0163] 5. The complex programmable logic device update module writes the value of the refresh variable into the baseboard management controller attribute table;

[0164] 6. The baseboard management controller reads the motherboard complex programmable logic device to obtain the server's power on / off status and writes it into the baseboard management controller attribute table;

[0165] 7. The complex programmable logic device update module reads the attribute table to obtain the power on / off status;

[0166] 8. The complex programmable logic device update module writes the unrefreshed flag bit and bus address and other information into the mainboard EEPROM;

[0167] 9. The CPLD update module writes the fan board CPLD register to refresh the CPLD;

[0168] 10. The shutdown refresh module shuts down the server by writing to the motherboard complex programmable logic device register;

[0169] 11. The shutdown refresh module reads the motherboard memory (specifically, the electrically erasable programmable read-only memory) to obtain information such as the unrefreshed flag and the fan board bus address;

[0170] 12. The shutdown refresh module writes the value of the refresh variable into the baseboard management controller attribute table;

[0171] 13. The shutdown refresh module writes the fan board complex programmable logic device register to refresh the complex programmable logic device;

[0172] 14. The lighting module reads the baseboard management controller attribute table to obtain the number of fans;

[0173] 15. The lighting module reads the baseboard management controller attribute table to obtain the fan speed and status;

[0174] 16. The lighting module reads the baseboard management controller attribute table to obtain the refresh variable value;

[0175] 17. The lighting module writes the fan board complex programmable logic device register.

[0176] In the method provided in this embodiment, by determining whether the fan board's complex programmable logic device has been refreshed, if the refresh is complete, the complex programmable logic device is rewritten to re-light the light. This method solves the problem of the fan indicator light not lighting up after the complex programmable logic device is refreshed because the baseboard management controller cannot sense the change in fan status. This method does not require restarting the baseboard management controller after refreshing the complex programmable logic device, thus avoiding the impact on the baseboard management controller's business. This method only rewrites the register corresponding to the complex programmable logic device fan indicator light once the complex programmable logic device is refreshed, without having to rewrite it every second, thus avoiding the waste of CPU resources and memory resources, and also avoiding the possible impact on software performance caused by hardware failures such as integrated circuit bus lines. Moreover, this method is compatible with both shutting down the computer to perform a complex programmable logic device update and performing a complex programmable logic device update.

[0177] It should be noted that the method provided in this embodiment is aimed at the problem that the fan indicator light does not light up after refreshing the complex programmable logic device of the fan board, but it is not limited to this problem. For example, other boards such as hard disk backplanes, motherboards, input and output boards, etc., if they have indicator lights or are not indicator lights but have only a few states, and the status is updated by writing the complex programmable logic device through the baseboard management controller after the state changes, this solution is applicable to them.
