Description

Baseboard management controller remote debugging system and method

The invention relates to a baseboard management controller (BMC) remote debugging system and method.

In the server system, the BMC is mainly responsible for the intelligent monitoring of the substrate. When the BMC is abnormal (such as the system crashes without a reason), the engineers usually check the running status of the BMC firmware (Firmware) through the debugging serial port. Analyze the cause of the anomaly and draw conclusions. However, in the server products that have been shipped, such as the cabinet server, the Debug port is usually not soldered, and even if there is a welding debug string, it is necessary to remove the boot case and connect the debug line. When debugging, after sending the Intelligent Platform Management Interface (IPMI) command from the client, you need to check the information returned from the debug serial port. This is cumbersome to operate, and there is also a risk of causing human damage to the product when the main casing is opened.

In view of the above, it is necessary to provide a BMC remote debugging system and method, which can enable a worker to conveniently diagnose, debug and test the user's BMC system at a remote location.

A BMC remote debugging system, the system includes: a receiving module, configured to receive a command sent by a remote terminal to switch the debugging mode of the BMC to a remote debugging when an abnormality occurs in the BMC; Acquiring the abnormal information of the abnormality of the BMC, and writing the abnormal information into the buffer one; the sending module is configured to send the abnormal information in the buffer one to the remote terminal through the network card; the receiving module The method is further configured to receive a debug command sent by the remote terminal for the abnormal information, and write the debug command into the buffer 2. The execution module reads the debug command for the abnormal information from the buffer 2. And execute the debug command to debug the BMC exception.

A BMC remote debugging method, the method includes: receiving step 1, when the BMC is abnormal, receiving a command sent by the remote terminal to switch the debugging mode of the BMC to the remote debugging; acquiring the step, acquiring the BMC Abnormal abnormal information occurs, and the abnormal information is written into the buffer one; the sending step sends the abnormal information in the buffer one to the remote terminal through the network card; and receiving step 2, receiving the remote terminal sending the The debug command of the exception information is written into the buffer 2; the execution step is to read the debug command for the exception information from the buffer 2, and execute the debug command to debug the BMC exception.

Compared with the prior art, the BMC remote debugging system can quickly connect the server system end to the serial port of the BMC through the multiplexer, which can conveniently control the serial port debugging of the BMC at a remote location.

2 is a block diagram of a remote debugging system of the substrate management controller of the present invention.

3 is a flow chart of a preferred embodiment of a method for remotely debugging a substrate management controller of the present invention.

As shown in FIG. 1 , it is an application environment diagram of the BMC remote debugging system of the present invention. The BMC remote debug system 34 is applied to the server 1 to debug the BMC 3. The server 1 further includes a serial port 31 and a network card 32. The BMC 3 includes a buffer one 33, a buffer two 35, a storage 36, and a processor 37. The server 1 communicates with the remote terminal 4 via the network card 32. The remote terminal 4 is configured to send a debugging command according to the BMC abnormality information when an abnormality occurs in the BMC.

The buffer one 33 is used to store abnormal information, such as a sudden crash when the BMC is booted to the kernel, a BMC 10 startup run to a certain thread suddenly crashes, a network error occurs when the BMC 10 is running, and the like.

The buffer 2 is used to store a debug command, and the debug command is a command of the debug BMC sent by the remote terminal 4 according to the abnormal information when the BMC is abnormal.

The serial port 31 is used for the serial output of the local output of the BMC operating state, and is used for locally debugging the BMC.

The remote terminal 4 can be a desktop computer, a notebook computer, a tablet computer, or the like.

As shown in Figure 2, it is a module diagram of the BMC remote debugging system. In this embodiment, the BMC remote debugging system 34 includes a setting module 340, a determining module 341, a triggering module 342, a receiving module 343, an obtaining module 344, a sending module 345, and an executing module 346. The module referred to in the present invention refers to a series of computer programs that can be executed by the processor 37 and that can perform fixed functions, which are stored in the storage unit 36. In the present embodiment, the functions of the respective modules will be specifically described in the flowchart of FIG.

As shown in FIG. 3, it is a flowchart of a preferred embodiment of the BMC remote debugging method of the present invention. The order of the steps in the flowchart may be changed according to different requirements, and some steps may be omitted.

In step S10, the setting module 340 sets an Original Equipment Manufacturer (OEM) command to control the debugging mode of the BMC 3. The debugging mode includes serial port debugging and remote debugging. For example, setting 0 means “serial debugging” and setting 1 means “remote debugging”. The default debugging mode of BMC 3 is serial debugging.

In the step S11, when the BMC 3 performs the serial port debugging, the determining module 341 determines whether the BMC is abnormal according to whether the abnormality information is recorded in the log log of the storage 36 of the BMC 3.

When the abnormality information is recorded in the log of the storage 36 of the BMC 3, the BMC has an abnormality, and the step S12 is performed. When the abnormality information is not recorded in the log of the storage 36 of the BMC 3, the BMC has no abnormality. End.

In step S12, the trigger module 342 triggers the remote terminal 4 to send an OEM command to switch the debugging mode of the BMC 3 to remote debugging.

In step S13, the receiving module 343 receives the OEM command sent by the remote terminal 4 to switch the debugging mode of the BMC to the remote debugging. In the performance of the operation interface, a debug mode selection window can be set in the display interface of the remote terminal 4, and when the remote terminal 4 is triggered to send an OEM command, the selection window appears and receives the customer's selection.

In step S14, the acquisition module 344 acquires the abnormality information of the abnormality of the BMC 3, and writes the abnormality information into the buffer 33.

In step S15, the sending module 345 sends the abnormal information in the buffer 33 to the remote terminal 4 through the network card 32.

In step S16, the remote terminal 4 analyzes the cause of the abnormality according to the received abnormal information, and sends a debug command of the abnormality. Corresponding to at least one debug command for each exception information.

In step S17, the receiving module 343 receives the abnormal debugging command sent by the remote terminal 4 by using the network card 32, and writes the debugging command into the buffer 235.

In step S18, the execution module 346 reads the abnormal debug command from the buffer two 35, and executes the debug command to debug the abnormality of the BMC 3.

After the abnormal debugging is completed, the trigger module 342 triggers the remote terminal 4 to send an OEM command to switch the debugging mode of the BMC 3 to the serial port debugging.

According to the present invention, the BMC remote debugging system can send the abnormal information to the remote terminal when the BMC is abnormal, and the remote terminal sends a debugging command to the BMC according to the abnormality to debug the abnormality of the BMC. In this way, there is no need to serialize the BMC, and remote diagnosis and debugging can greatly facilitate the system development, debugging and testing of the staff.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
