Detailed ways

The core of the present invention is to provide a method for recording abnormal state of a server, which can obtain a more specific working state of the server when the state of the server is abnormal, which is also conducive to subsequent failure cause analysis and failure resolution.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is an implementation flowchart of a method for recording an abnormal state of a server according to the present invention. The method for recording an abnormal state of a server is applied to a BMC (Baseboard Management Controller, baseboard management controller), and may include the following steps :

Step S101: Receive a first instruction sent by the BIOS indicating that the server state is abnormal.

The BIOS can learn whether the server is currently in an abnormal state. Specifically, the abnormal state of the server described in this application refers to the abnormal state of the operating system of the server, such as abnormal shutdown. The BIOS can determine that the server is currently in an abnormal state through the relevant interrupt signal.

When the BIOS determines that the server is in an abnormal state, it will actively send the first command, and after the BMC receives the first command, it can determine that the server state is abnormal.

Step S102: After receiving the first instruction, obtain the VGA signal of the server and store it, and record the abnormal state of the server by recording the screen.

After receiving the first command, the BMC determines that the server state is abnormal, and will actively obtain the VGA (Video Graphics Array, video graphics array) signal in the server. The VGA signal can reflect the specific working state of the server, that is, the specific execution of the relevant process. .

The BMC will record the abnormal status of the server by recording the screen. It should be noted that the screen recording described in this application means that the BMC will continuously obtain the VGA signal, so that after parsing the VGA signal obtained by the BMC, the staff You can view the specific working status of the server when an abnormality occurs through video, instead of restricting the BMC or the server to have a display screen.

After the BMC obtains the VGA signal of the server, it can be compressed first and then stored. The storage location can also be set and selected as needed. For example, the BMC can compress and store the recorded video in the TF card of the server.

When acquiring the VGA signal, the VGA signal can usually be acquired from the ASPEED chip. For example, in a specific implementation manner, the operation of acquiring and storing the VGA signal of the server described in step S102 may be specifically: from and PCH (Platform The VGA signal of the server is obtained from the ASPEED AST2500 chip connected to the Controller Hub (integrated south bridge) and stored.

In a specific embodiment of the present invention, after step S102, it may further include:

receive data analysis instructions;

After receiving the data analysis command, analyze the stored VGA signal, and display the analyzed video on the BMC WEB.

In this embodiment, in order to facilitate the staff to perform data analysis, after receiving the data analysis instruction, the stored VGA signal can be parsed, and the parsed video can be displayed on the BMC WEB, that is, the staff can use any device After logging in to the BMC WEB, you can easily view the video data, so as to analyze the failure of the server based on the specific working state of the server when it is in an abnormal state.

By applying the technical solution provided by the embodiment of the present invention, when the BIOS detects that the server state is abnormal, it will actively send a first instruction indicating that the server state is abnormal to the BMC. After the BMC receives the first instruction, it will obtain the VGA signal of the server and carry out Storage, the VGA signal can record the specific working status of the server. Therefore, BMC can record the working status of the server in an abnormal state by recording the screen, which is conducive to saving more and more specific server status information. Therefore, the solution of the present application can obtain a more specific working state of the server when the state of the server is abnormal, which is also conducive to subsequent failure cause analysis and failure resolution.

In a specific embodiment of the present invention, it can also include:

In the process of acquiring and storing the VGA signal of the server, when receiving the second instruction sent by the BIOS indicating that the server state is restored to normal, the acquisition of the VGA signal of the server is stopped.

It can be understood that the server will automatically return to the normal state after some abnormal conditions occur, for example, by restarting to return to the normal state. After the server returns to the normal state, there is no need to continue screen recording. Therefore, in this embodiment, , when the BIOS detects that the server is back to normal, it will actively send a second instruction to the BMC, and once the BMC receives the second instruction, it will stop acquiring the VGA signal. This implementation can avoid acquiring invalid data.

In a specific embodiment of the present invention, it can also include:

In the process of acquiring and storing the VGA signal of the server, when the duration of the inability to acquire the VGA signal reaches the preset first duration, the acquisition of the VGA signal of the server is stopped.

Considering that in some occasions, the server will be completely shut down and powered down, and the BMC will no longer be able to obtain the VGA signal. Therefore, in this implementation manner, when the BMC obtains the VGA signal of the server and stores it, when the When the duration of the inability to acquire the VGA signal reaches the preset first duration, it means that the VGA signal of the server can no longer be acquired, and the acquisition of the VGA signal can be stopped, so as to avoid continuously querying whether the VGA signal can be acquired. LF. The value of the first duration can also be set and selected as required.

In a specific embodiment of the present invention, it can also include:

When the duration of acquiring the VGA signal of the server reaches a preset second duration, stop acquiring the VGA signal of the server.

In this implementation, considering that the storage space for storing VGA signals is limited, continuously acquiring too many VGA signals may cause the storage space to be exhausted, and in general, the server will not be in a state where VGA signals can be acquired for a long time. The abnormal state, that is, it is either restored to normal by means of restarting or the like, or completely shut down, and the VGA signal can no longer be acquired by the BMC. Therefore, a second duration is set in this implementation manner. The specific value of the second duration can be set and adjusted according to the actual situation, for example, set to 10 minutes. When the duration of acquiring the VGA signal of the server reaches the preset second duration, the acquisition of the VGA signal of the server is stopped, which can prevent the server from being in an abnormal state in which the BMC can continuously acquire the VGA signal in special occasions. Occurrence of running out of storage space.

In a specific embodiment of the present invention, it can also include:

After receiving the first instruction, the hardware display device is used to prompt the abnormal state of the server, and at the same time, the abnormal state of the server is prompted on the BMCWEB.

When the BMC receives the first instruction, it means that the server is in an abnormal state. Therefore, the BMC can display the abnormal state of the server through the hardware display device, such as flashing indicator lights, switching colors, etc., which is helpful for the on-site staff to find the abnormal situation in time. At the same time, the abnormal status of the server will be prompted on the BMC WEB, which is helpful for remote staff to notice the abnormal situation in time after logging in to the BMC WEB.
