Description
Technical Field
The present application relates to the field of server technologies, and in particular, to an Intelligent Platform Management Interface (IPMI) command processing method, a server, and a non-transitory computer-readable storage medium.
Background
The server's motherboard Management Controller (BMC) needs to handle the external interfaces of the server (e.g., System Interface (System Interface) for IPMI communication with the BMC, and the Intelligent platform Management bus Interface (I-based) for IPMI communication with the BMC2IPMI communication interface of C), IPMI communication interface for IPMI communication with BMCA trusted network Interface (LAN Interface)) to send an IPMI request command. The IPMI request commands sent by all external interfaces are processed sequentially through a Message Handler (Message Handler) activated by the BMC. If the message processing module calls the exception according to the IPMI request command, the subsequent IPMI request command cannot be processed and responded, and finally the external IPMI command interface (i.e. the external interface) of the BMC is completely disabled.
In summary, a technical problem to be solved by the present invention is to provide a method for processing an IPMI command, so that when an IPMI request command is processed by a message processing module activated by a BMC abnormally, the IPMI request command sent by a subsequent external interface can still be processed and responded.

The embodiment of the application provides an IPMI command processing method, a server and a non-transitory computer readable storage medium, which solve the problem that a message processing module started by a BMC cannot process subsequent IPMI request commands due to exception in IPMI request command processing, and finally all external IPMI command interfaces of the BMC are invalid.
In order to solve the technical problem, the present application is implemented as follows:
in a first aspect, an embodiment of the present application provides an IPMI command processing method, which includes the following steps: the main process of the BMC starts an active message processing module and a standby message processing module; the active message processing module receives and executes corresponding processing and response according to an IPMI request Command in an IPMI Command Queue (IPMI Command Queue) after being started; the standby message processing module continuously detects the state of the active message processing module after being started; when the standby message processing module detects that the active message processing module is in an abnormal state, the standby message processing module automatically replaces the active message processing module to execute work, resets the repairing active message processing module, and continuously detects whether the repairing of the active message processing module is finished; and when the standby message processing module detects that the active message processing module is repaired, the standby message processing module enters a sleep mode, and the active message processing module operates again.
In a second aspect, an embodiment of the present application provides a server, which includes: one or more processors, and a memory.

It will be understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, values, method steps, operations, components, and/or components, but do not preclude the presence or addition of further features, values, method steps, operations, components, and/or groups thereof.

In contrast, when an element is described as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.
Please refer to fig. 1, which is a flowchart illustrating an IPMI command processing method according to an embodiment of the present application. In this embodiment, the IPMI command processing method may be applied to the BMC of the server, as shown in fig. 1, and includes the following steps: the main process of the BMC starts an active message processing module and a standby message processing module (step 11); the active message processing module receives the IPMI request command in the IPMI command queue after being started and executes corresponding processing and response according to the IPMI request command in the IPMI command queue (step 12); the standby message processing module continuously detects the state of the active message processing module after being started (step 13); when the standby message processing module detects that the active message processing module is in an abnormal state, the standby message processing module automatically replaces the active message processing module to execute work, resets and repairs the active message processing module, and continuously detects whether the active message processing module is repaired (step 14); and when the standby message processing module detects that the active message processing module is repaired, the standby message processing module enters a sleep mode, and the active message processing module resumes operation (step 15).
More specifically, under normal conditions, the active message processing module sequentially processes and responds to the IPMI request commands in the IPMI command queue after being started, and the standby message processing module does not receive the IPMI request commands in the IPMI command queue after being started, and only continuously detects the state of the active message processing module; when the active message processing module cannot normally work due to the fact that the IPMI request command is processed abnormally, the standby message processing module enters an operation mode, immediately replaces the active message processing module to execute work (namely, continuously receives and executes corresponding processing and response according to the IPMI request command in the IPMI command queue), can process subsequent IPMI request commands without intervals, and repairs the active message processing module; when the standby message processing module detects that the active message processing module is repaired, the standby message processing module returns the IPMI request command processing permission to the active message processing module and continuously detects the state of the active message processing module (i.e., enters a sleep mode), and the active message processing module resumes normal operation (i.e., continuously receives and executes corresponding processing and responding according to the IPMI request command in the IPMI command queue). Therefore, the problem that the subsequent IPMI request command cannot be processed due to the exception of the active message processing module can be avoided.
It should be noted that the active message processing module and the standby message processing module may be, but are not limited to, the same message processing module, and the difference between the two modules is that the roles are different (i.e. under normal conditions, the active message processing module is a message processing module in an operation mode, and the standby message processing module is a message processing module in a sleep mode; when the active message processing module is abnormal, the standby message processing module is changed to the message processing module in the operation mode; and the active message processing module is repaired to be the message processing module in the operation mode, and the standby message processing module is changed back to the message processing module in the sleep mode).
In an embodiment, in step 11, the main process of the BMC may start the active message processing module and the standby message processing module at the same time.
In another embodiment, in step 11, the main process of the BMC may start the active message processing module and the standby message processing module sequentially. It should be noted that the standby message handling module needs to be started by the main process of the BMC during the normal operation of the active message handling module.
In an embodiment, before step 12, the IPMI command processing method may further include: the external interface sends the IPMI request command to the IPMI command queue through Inter-Process Communication (IPC) (step 10). The external interface may be, but not limited to, a system interface for IPMI communication with the BMC, an intelligent platform management bus interface, and a network interface. That is, the IPMI request commands sent by the external interface are sequentially stored in the IPMI command queue, and the IPMI request command stored in the IPMI command queue at the earliest time is processed by the active message processing module at the earliest time. In another embodiment, the step 10 may also be performed before the step 11.
In one embodiment, the step 12 of receiving and executing the corresponding process and response according to the IPMI request command in the IPMI command queue may include: and receiving and calling a corresponding processing program according to the IPMI request command in the IPMI command queue for processing, and returning a processing result to an external interface sending the IPMI request command. In this embodiment, the transmitting the processing result back to the external interface sending the IPMI request command may include: and returning the processing result to an external interface sending the IPMI request command through a corresponding Response Queue (Response Queue). In one example, when the IPMI request command being processed is sent by a network interface, the processing result is returned to the network interface via a network echo queue. In another example, when the IPMI request command to be processed is sent by a system interface, the processing result is returned to the system interface through a system response queue. In yet another example, when the IPMI request command to be processed is sent by the IPMI interface, the processing result is returned to the IPMI interface via the IPMI response queue.
In an embodiment, the IPMI command processing method may further include: after receiving an IPMI request command in an IPMI command queue, the active message processing module sets a Timeout counter value (namely the value of u8 RemainTimeoutMs) and sets a Timeout flag bit (namely Timeout) to be 1 so as to start a timer thread, wherein the Timeout counter value is greater than or equal to a default counter value; the timer thread decrements the timeout counter value after starting until the timeout counter value is reduced to 0; and when the standby message processing module detects that the overtime flag bit is 1 and the value of the overtime counter is reduced to 0, the standby message processing module detects that the active message processing module is in an abnormal state. The time corresponding to the default counter value is the time required by the active message processing module to normally process an IPMI request command; the timeout flag bit and the timeout counter value may be stored in a shared Memory (Share Memory); the timer thread may decrement the timeout counter value by one every millisecond until the timeout counter value is decremented to 0; however, the present embodiment is not limited to the present application, and can be adjusted according to actual requirements. In this embodiment, the IPMI command processing method may further include: after the active message processing module processes and responds to an IPMI request command each time, the overtime flag bit is set to be 0. Therefore, when the standby message processing module detects that the timeout flag bit is 0, the standby message processing module detects that the active message processing module is in a normal state.
In one embodiment, in step 14, the reset repair active message processing module may include: killing the active message processing module; and restarting the active message processing module and setting the timeout flag bit to 0. In other words, the timeout flag is cleared after the active message processing module is restarted. In this embodiment, the IPMI command processing method may further include: when the standby message processing module detects that the overtime flag bit is 0, the active message processing module is detected to be repaired. In other words, the standby message processing module determines whether the active message processing module completes repairing by detecting the timeout flag bit of the active message processing module.
In an embodiment, before step 15, the IPMI command processing method may further include: after each processing and responding to an IPMI request command, the standby message processing module detects whether the active message processing module completes the repair (step 16). In another embodiment, the standby message processing module may continuously detect whether the active message processing module completes repairing. In yet another embodiment, the standby message processing module may periodically and continuously detect whether the active message processing module is repaired.
In an embodiment, the IPMI command processing method may further include: the active message processing module puts the IPMI request command into the shared memory after receiving the IPMI request command in the IPMI command queue each time; and when the standby message processing module judges that the active message processing module is in an abnormal state, the standby message processing module reads the IPMI request command finally put into the shared memory and executes corresponding processing and response. Therefore, the standby message processing module can not only continuously process and respond to the IPMI request command in the IPMI command queue, but also process and respond to the IPMI request command causing the exception of the active message processing module.
Please refer to fig. 2, which is a schematic structural diagram of a server according to an embodiment of the present application. As shown in fig. 2, the server 2 includes: one or more processors 21 and memory 22, the memory 22 being used to store one or more computer programs 221. When executed by the one or more processors 21, the one or more computer programs 221 cause the one or more processors 21 to implement the IPMI command processing method described above. The one or more computer programs 221 may be, but not limited to, software programs, computer-executable programs, and modules, such as modules corresponding to the IPMI command processing method in the above-described embodiment (for example, an active message processing module and a standby message processing module), and the processor 21 executes various functional applications and data processing of the server 2 by running the software programs, the computer-executable programs, and the modules stored in the memory 22, so as to implement the above-described IPMI command processing method.
In the present embodiment, fig. 2 only shows one processor 21 and one program 221 as an example; the processor 21 and the memory 22 in the server 2 may be connected by a bus or other means, and fig. 2 illustrates the connection by a bus as an example.
In the present embodiment, the memory 22 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function, and the like; the storage data area may store various data. Further, the memory 22 may include a high speed random access memory, and may also include a non-volatile memory, such as: at least one magnetic disk storage device, flash memory device, or other non-volatile solid state storage device.
Please refer to fig. 3, which is a schematic structural diagram of a non-transitory computer-readable storage medium according to an embodiment of the present application. As shown in fig. 3, the non-transitory computer-readable storage medium 3 stores a computer program 31, and the computer program 31 implements the IPMI command processing method described above when executed by a processor. The non-transitory computer readable storage medium 3 may be, but is not limited to, a Read-Only Memory (ROM), a magnetic disk or an optical disk.
In summary, in the embodiment of the present application, the design of the two message processing modules (i.e., the active message processing module and the standby message processing module) is started by the main process of the BMC, so that when the active message processing module processes an IPMI request command abnormally, the standby message processing module immediately replaces the active message processing module to execute work, and can process subsequent IPMI request commands without an interval. In addition, the standby message processing module can also repair the active message processing module, and the IPMI request command processing authority is returned to the active message processing module after the active message processing module is repaired. In addition, through the design of the timeout counter value and the timeout flag bit, the standby message processing module can detect the state of the active message processing module and confirm whether the active message processing module completes repairing. Furthermore, the active message processing module puts the received IPMI request command into the shared memory each time, so that the standby message processing module can process and respond to the IPMI request command in the IPMI command queue in a continuous manner and can process and respond to the IPMI request command causing the abnormality of the active message processing module.
Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present application may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for causing a server to execute the methods according to the embodiments of the present application.

Rather, this invention encompasses modifications and similar arrangements as would be apparent to one skilled in the art. The scope of the claims is, therefore, to be construed in the broadest manner to include all such obvious modifications and similar arrangements.
