Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a mirror file management method, device, computer equipment and storage medium. Background Art

[0002] The rapid development of the Internet has also brought prosperity to the server market. During the startup and operation of the OpenPower server, the BIOS needs to frequently interact with the BMC to read and write the BIOS image.

[0003] The current method of reading and writing BIOS images for OpenPower servers is based on the IPMI protocol and the LPC bus. Since the speed of the BMC reading and writing the flash memory chip that stores the BIOS image is very slow, the protocol adopts the method of first loading the BIOS image into the BMC memory, directly reading and writing the memory, and finally writing the flash memory chip in a centralized manner. However, this easily causes the problem of the contents in the BMC memory and the flash memory chip being out of sync. Once the system is powered off or the BMC restarts abnormally, data will be lost. In addition, since the protocol involves two transmission processes, namely IPMI information and LPC bus reading and writing, the implementation is complex. One reading and writing requires multiple information transmissions, and the transmission speed is slow. In addition, both the BMC and the BIOS need to retain a large amount of runtime information. If one end is restarted, the runtime information of both parties is not equal, which may cause reading and writing abnormalities. Summary of the invention

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The rapid development of the Internet has also brought prosperity to the server market. During the startup and operation of the OpenPower server, the BIOS needs to frequently interact with the BMC to read and write the BIOS image.

[0043] The current method of reading and writing BIOS images for OpenPower servers is based on the IPMI protocol and the LPC bus. Since the speed of the BMC reading and writing the flash memory chip that stores the BIOS image is very slow, the protocol adopts the method of first loading the BIOS image into the BMC memory, directly reading and writing the memory, and finally writing the flash memory chip in a centralized manner. However, this easily causes the problem of the contents in the BMC memory and the flash memory chip being out of sync. Once the system is powered off or the BMC restarts abnormally, data will be lost. In addition, since the protocol involves two transmission processes, namely IPMI information and LPC bus reading and writing, the implementation is complex. One reading and writing requires multiple information transmissions, and the transmission speed is slow. In addition, both the BMC and the BIOS need to retain a large amount of runtime information. If one end is restarted, the runtime information of both parties is not equal, which may cause reading and writing abnormalities.

[0044] In view of this, the present invention provides an image file management method, which can realize image file management with only a single transmission mode, has a simple implementation method and a fast transmission speed, and before each reading and writing, it is necessary to first obtain a string list, i.e., runtime information, from the BMC external file system, thereby avoiding the problem that when both the image system and the BMC need to retain a large amount of runtime information, one end is restarted, and the runtime information of both parties is not equal, which may cause reading and writing abnormalities, thereby solving the problem of information asymmetry.

[0045] The following is a detailed description, please refer to Figure 1 , Figure 1 A flowchart of an image file management method provided by an embodiment of the present invention. An image file management method according to an embodiment of the present invention may include:

[0046] Step S101: Obtain file operation instructions and target file information.

[0047] In the embodiment of the present invention, the form of the file operation instruction is not limited, and it can be a small piece of data code, a specific high level or low level, or an identifier, etc., and the required form can be determined according to actual conditions. Among them, in the embodiment of the present invention, the instruction content of the file operation instruction is not limited, and it can be a file operation instruction for reading file information or a file operation instruction for writing file information.

[0048] Step S102: According to the target file information, the file ID corresponding to the target file information is determined using the string list.

[0049] In the embodiment of the present invention, the target file information includes information such as the file name of the file information being operated, and the string list is list information including the file ID (ID is the file number) and the file name of the file information. It should be noted that the file ID and the file name of the file information correspond one to one in the string list, wherein the file ID is a unique identifier used to represent the file information. There is no restriction on the form of the file ID, and the file ID can be represented by a column of numbers or a column of letters.

[0050] It should be noted that, in the embodiment of the present invention, the string list can be read according to the target file information using the platform level data model (PLDM) protocol, and then the file ID corresponding to the target file information can be determined according to the string list, wherein PLDM is a platform level data model. Specifically, in the embodiment of the present invention, it can be determined whether there is a file name corresponding to the file name of the target file information in the string list. If there is a corresponding file name, the file ID corresponding to the file name is determined according to the file name. If there is no corresponding file name, the operation is exited. For example, when there is a file name SectionName1 in the target file information, the string list is read using the PLDM protocol. If there is a file ID lidid1 corresponding to the file name SectionName1 in the read string list, the file ID lidid1 is obtained. If there is no corresponding file name, the operation is exited.

[0051] In the embodiment of the present invention, the string list is read by using the PLDM protocol, and a single protocol is used for reading, which is simple to implement and has a fast transmission speed.

[0052] Step S103: According to the file ID, determine the file information corresponding to the file ID, and operate the file information according to the file operation instruction.

[0053] In the embodiment of the present invention, the file information corresponding to the file ID can be determined according to the file ID. It should be noted that, it is possible to first determine whether the corresponding file ID exists in the file list according to the file ID. If the corresponding file ID exists, the file list is used to determine the file information corresponding to the file ID. If the corresponding file ID does not exist, the operation is exited. The file list is list information including the file ID and the file information, and the file ID and the file information correspond one to one in the string list. For example, the code fileName=lidid n.lid can be used to determine whether the corresponding file ID exists in the file list, where lidid n.lid is the file ID.

[0054] In the embodiment of the present invention, the file information can be operated according to the file operation instruction. Specifically, if the file operation instruction is a read instruction, it is necessary to return the relevant file information data after reading the file information. If the file operation instruction is a write instruction, it is necessary to write the corresponding data in the corresponding file information.

[0055] Based on the above embodiments, the embodiments of the present invention provide an image file management method, which can realize image file management with only a single transmission mode, has a simple implementation method and a fast transmission speed, and before each reading and writing, it is necessary to obtain a string list, that is, runtime information, from the BMC external file system. In this way, when both the image system and the BMC need to retain a large amount of runtime information, one end is restarted, and the runtime information of both parties is not equal, which may cause reading and writing abnormalities, thereby solving the problem of information asymmetry.

[0056] Please refer to Figure 2 , Figure 2 This is a flow chart of another image file management method provided by an embodiment of the present invention. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution.

[0057] Step S201: storing file information by mounting.

[0058] In the embodiment of the present invention, mounting is a process by which the operating system makes computer files and directories on a storage device such as a hard disk, a read-only compact disk (CD-ROM) or a shared resource accessible to users through the computer's file system.

[0059] It should be noted that, in the embodiment of the present invention, image file information can be received, the image file information can be split to obtain file information, and then, according to the file information, the file ID and the name of the file information are matched one by one to establish a string list, and the file information and the string list are stored in a baseboard management controller (BMC) external file system, wherein the image file information can be the file information stored in the BIOS (basic input / output system) image, and the BMC is a baseboard management controller responsible for managing the interface between the system management software and the platform hardware. In the embodiment of the present invention, there is no restriction on the BMC external file system, which can be a multimedia card (MMC) external to the BMC, or a storage card external to the BMC. Specifically, for example, the entire BIOS image file can be divided into multiple sections, and the name of each section and the file ID can be matched to form a string variable list, and then the BMC can split the BIOS image into multiple binary files and the string list according to the section and store them in the BMC external MMC card, and use the MMC card as the actual BIOS image, wherein the section can be obtained by splitting the entire file of the BIOS image. In this way, when the BMC is turned on, two runtime variables can be updated according to the content of the BIOS image section file in the file system, that is, the MMC card. One is a file list, which stores the file name and unique file ID of each file, and the other is a string variable list, which stores the name of each section of the BIOS image and the corresponding unique file ID.

[0060] In the embodiment of the present invention, file information can be stored in a mounting manner, and the BIOS image can be directly loaded into the BMC memory by mounting the file, thereby avoiding the problem of information asymmetry between the flash memory chip and the BMC memory, and further avoiding the reading and writing abnormality caused by information asynchrony.

[0061] Step S202: Obtain file operation instructions and target file information.

[0062] For the specific content of the above step S202, reference may be made to the corresponding content disclosed in the above embodiments, which will not be repeated here.

[0063] Step S203: According to the target file information, the file ID corresponding to the target file information is determined using the string list.

[0064] For the specific content of the above step S203, reference may be made to the corresponding content disclosed in the above embodiments, which will not be repeated here.

[0065] Step S204: Send the file ID to the BMC.

[0066] In the embodiment of the present invention, the file ID can be sent to the BMC. It should be noted that there is no limitation on the sending method. The file ID can be sent to the BMC using a data transmission protocol. Specifically, the file ID and the location and data of the file information being operated can be sent to the BMC using the PLDM protocol. The file ID can also be sent to the BMC using other methods.

[0067] Step S205: The BMC determines the file information corresponding to the file ID according to the file ID, and operates the file information according to the file operation instruction.

[0068] In the embodiment of the present invention, after the BMC receives the file ID, the file information corresponding to the file ID can be determined according to the file ID, and the file information can be operated according to the file operation instruction. Specifically, for example, after the BMC receives the file ID, the file information corresponding to the file ID can be determined from the file list of the MMC card according to the file ID, and then the file information can be operated according to the file operation instruction, wherein the MMC card is a multimedia card which is a small erasable solid-state memory card.

[0069] Based on the above embodiments, the embodiments of the present invention provide an image file management method, which uses a mounting method to store file information, and directly loads the BIOS image into the BMC memory by mounting the file, thereby avoiding the problem of information inequality between the flash memory chip and the BMC memory, and further avoiding the reading and writing abnormalities caused by information asynchrony. In addition, before each reading and writing, it is necessary to obtain a string list, that is, runtime information, from the BMC external file system. In this way, when both the image system and the BMC need to retain a large amount of runtime information, one end is restarted, and the runtime information inequality of both parties may cause the reading and writing abnormalities, thereby solving the problem of information inequality.
