DETAILED DESCRIPTION

[0028] The technical solutions in some embodiments of the present application will be described below in conjunction with the drawings in some embodiments of the present application.

[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] Normally, various status monitoring, related log records, KVM remote operation and maintenance of the server require the BMC to work properly and can only operate when the BMC network is accessible. However, in some special environments, it may be difficult to access the BMC network, or the BMC itself has no network connection. The existing BMC function is already very powerful. It can monitor various states of the server and make log records, and can also be remotely operated through KVM. The baseboard management controller (Board Management Controller, BMC) is often referred to as the baseboard management controller in the hardware field. It is a dedicated microcontroller embedded in the server motherboard or blade server. Its main task is to monitor the hardware status of the server, including temperature, voltage, fan speed, etc., to ensure the stable operation of the server. When an abnormality is detected, the BMC can automatically perform fault recovery or alarm, thereby improving the reliability and availability of the server. In addition, the BMC also supports remote management functions, allowing administrators to easily monitor and manage the server through the remote access interface.

[0031] However, all operations require normal BMC network access. However, different computer rooms may have different network configurations. After connecting the operation and maintenance computer to the switch via a network cable, you may encounter various problems such as being unable to know the BMC IP of the problem server, complex network segments, and IP address conflicts, which may lead to BMC network inaccessibility. There are even cases where the BMC is completely disconnected from the network and runs offline in some computer rooms for special purposes. The different levels of operation and maintenance personnel in the computer room may also make the operation more complex and changeable. Therefore, how to quickly and easily extract BMC log information, or extract BMC log information without network access, and simplify operator operations is an optimizable problem.

[0032] In view of this, some embodiments of the present application provide a log extraction method in a non-network state, the method comprising: detecting a preset interface on a server in a non-network state; obtaining pre-stored log data when it is detected that an extraction device is connected to the preset interface; storing the pre-stored log data on the extraction device. In an embodiment of the present application, a USB interface connected to the BMC is used as a preset interface, and the log data is stored when the BMC has a network. In this way, if there is no network and it is detected through the preset interface that an extraction device is inserted, the pre-stored log data is stored on the extraction device, so that the log data on the BMC can be extracted in a non-network state.

[0033] like Figure 1 As shown, an embodiment of the present application provides a log extraction method without a network state, the method comprising: S101, in the absence of a network state, detecting a preset interface on a server; Specifically, the embodiment of the present application is applied to a storage server. A BMC and a storage device are provided inside the storage server. A plurality of USB interfaces are provided outside the storage server, and the BMC is connected to one of the USB interfaces.

[0034] If the BMC is in a state of no network, the BMC detects the preset interface on the storage server, that is, the USB interface connected to the BMC.

[0035] S102, when it is detected that an extraction device is connected to a preset interface, obtaining pre-stored log data; Specifically, if the BMC detects that an extraction device is connected to the preset interface, the pre-stored log data is obtained from the storage device.

[0036] That is to say, when designing the storage server, the USB channel of the BMC needs to be pulled out and made into an interface appearance to facilitate the connection and extraction of devices, such as a USB flash drive.

[0037] S103: Store the pre-stored log data on the extraction device.

[0038] Specifically, after detecting the extraction device, the BMC automatically stores the pre-stored log data on the extraction device. For example, after recognizing the USB flash drive connection, the BMC can automatically transfer the relevant log information at the time of connection (such as BMC one-click collection log, all BIOS log information of the day, firmware extraction, etc.) to the USB flash drive.

[0039] The implementation method of the embodiment of the present application is to use the USB interface of the BMC channel. The operator only needs to connect a USB flash drive device with a special interface (such as USB-C) to the USB interface connected to the BMC, and various logs saved in advance by the BMC can be automatically saved to the USB flash drive. The operator can unplug the USB flash drive after waiting for a few minutes and connect it to any computer to view relevant log information, thereby realizing the extraction of log data on the BMC without a network.

[0040] Some embodiments of the present application use the USB interface connected to the BMC as a preset interface, and store log data when the BMC has a network. In this way, if there is no network and the preset interface detects that an extraction device is inserted, the pre-stored log data is stored on the extraction device, so that the log data on the BMC can be extracted when there is no network.

[0041] Another embodiment of the present application further supplements the log extraction method without network status provided in the above embodiment.

[0042] Optionally, obtain pre-stored log data, including: Obtain pre-stored log data within a preset time period from a pre-set storage device, wherein the pre-set storage device includes at least an eMMC storage chip or an SD card, and the log data includes at least all log information of the BIOS on that day, firmware extraction information, and sensor data, and the sensor data includes at least current values, voltage values, and temperature values ​​of each node.

[0043] BIOS log information and other information may require a large space to save, and real-time sensor information (voltage value, current value, temperature value) will also use a large capacity to save. BMC usually reserves an SD channel to connect the eMMC storage chip or SD card. BMC saves the logs collected by BMC one-click, all BIOS log information of the day, firmware extraction information, and sensor information to the storage device at preset time intervals or as needed.

[0044] In some embodiments of the present application, when the network status is normal, the BMC stores relevant log information during connection (such as BMC one-key collection log, all log information of the BIOS on the day, firmware extraction, etc.) and sensor data in a storage device.

[0045] Optionally, in the absence of a network state, a preset interface on the server is detected, including: In the absence of a network connection, the preset USB interface on the server is tested.

[0046] In some embodiments of the present application, when there is no network, the BMC detects a preset USB interface on the storage server to determine whether an extraction device is inserted.

[0047] Specifically, Figure 3 As shown in the figure, the storage server pulls out the SD channel of the BMC and connects it to the eMMC storage or SD (Secure Digital Memory Card) card as a log cache space. Pull out the USB channel of the BMC and connect it to the USB interface that can be connected to the server to facilitate the connection of the USB disk.

[0048] When the BMC is not connected to the network and needs to extract the log data of the BMC storage device, the user can insert a USB flash drive into the preset USB interface. The BMC will detect the preset USB interface to determine whether there is an extraction device, that is, a USB flash drive inserted.

[0049] Optionally, the method further comprises: The UID light determines the transmission status of storing the pre-stored log data to the extraction device.

[0050] Specifically, the storage server is provided with a UID light. When the UID light of the server is on, it indicates that the unique identifier (UID) of the storage server is active. For example, when the network status of the storage server is normal, the UID light can identify whether remote data access is normal. If there is no network status, the different states of the UID light are used in the embodiment of the present application to identify the status of log writing to the USB flash drive. A fixed frequency combination can be used to flash to indicate the transmission status, so as to facilitate the operator to confirm when the USB flash drive can be removed.

[0051] Optionally, the UID light is used to determine the transmission status of storing the pre-stored log data on the extraction device, including: Different transmission states are determined according to the flashing frequency and flashing time of the UID light.

[0052] In the embodiment of the present application, the frequency and flashing time of the UID light can be set according to needs, so that different states can determine the transmission state of writing log data into the extraction device.

[0053] For example, if the UID light does not flash, it means that the transmission has not started; If the UID light flashes once at 1Hz and twice at 4Hz in a cycle, it means data is being written; If the UID light flashes once at a slow speed of 1 Hz, flashes four times at a fast speed of 4 Hz, and stops flashing for 2 seconds in a cycle, it means that the data has been sent.

[0054] In the embodiment of the present application, the flashing time may include the number of flashes or the duration of the light being on, which is not specifically limited here.

[0055] Some embodiments of the present application determine the transmission status of storing pre-stored log data on the extraction device by setting the flashing frequency and flashing time of the UID light, so that the progress of log extraction can be known in a timely manner.

[0056] like Figure 2 As shown, some embodiments of the present application provide a log extraction method without a network state, including: 1. After the BMC completes the startup and recognizes that the storage server is started, it records the BIOS serial port log in real time and saves it to the SD card / eMMC storage, generating a new file every day / each new startup.

[0057] 2. The BMC saves all sensor data information of the storage server to the SD card / eMMC storage every 1 minute (for example). The sensor data information includes the voltage value, current value, and temperature value of each node.

[0058] 3. When BMC detects that a USB flash drive has been inserted, it automatically saves the BIOS log generated on the day and all server sensor information files recorded in the last hour to the root directory of the USB flash drive.

[0059] 4. After the above files are sent, a one-key collection log is automatically generated and stored in a USB flash drive.

[0060] 5. During data transmission, the UID light flashes once at a slow speed of 1 Hz and flashes twice at a fast speed of 4 Hz in a cycle, indicating that data is being written.

[0061] 6. After all data has been sent, the UID light will flash once at 1Hz, flash four times at 4Hz, and stop flashing for 2 seconds, indicating that the data has been sent and the USB flash drive can be removed.

[0062] 7. Under BMC WEB, reserve relevant settings such as BIOS log preservation, sensor information preservation switch and preservation cycle time.

[0063] 8. The flashing mode of the UID light, storage cycle time, etc. can be adjusted as required.

[0064] It should be noted that each implementable method in this embodiment may be implemented separately, or may be implemented in combination in any combination without conflict, and this application is not limited thereto.

[0065] Another embodiment of the present application provides a log extraction device in a non-network state, which is used to execute the log extraction method in a non-network state provided by the above embodiment.

[0066] like Figure 4 , which is a schematic diagram of the structure of a log extraction device without network status provided by an embodiment of the present application. The log extraction device without network status includes a detection module 401, an acquisition module 402 and a storage module 403, wherein: The detection module 401 is used to detect the preset interface on the server in the absence of network status; The acquisition module 402 is used to acquire pre-stored log data when detecting that an extraction device is connected to a preset interface; The storage module 403 is used to store the pre-stored log data on the extraction device.
