Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a BMC upgrading method, a BMC upgrading device, BMC upgrading equipment and a computer readable storage medium, which are used for rapidly upgrading a BMC and avoiding the problem that the BMC is failed to start or functions are lost due to damage of written content caused by overlong upgrading time.
Referring to fig. 1, a schematic flow diagram of a BMC upgrading method provided in an embodiment of the present invention is shown; the method specifically comprises the following steps:
s101, receiving a Firmware file to be written into the BMC;
wherein the Firmware file comprises a header area and a predetermined number of content storage areas. The predetermined number of content storage areas includes: the system comprises an uboot storage area, a kernel storage area, a file system storage area, a configuration file storage area and an application program storage area.
It should be noted that, in the existing BMC upgrading scheme, Firmware is written into corresponding Flash as a whole, and if BMC is upgraded by using the original upgrading scheme, 32M content needs to be written into Flash completely when BMC Firmware is upgraded by a client server, so that the time spent is long, the image damage probability is increased, the probability of influencing the startup and the normal operation of functions of the server is correspondingly increased, and troubles are caused to the client.
Therefore, in the application, in order to shorten the upgrading time, the Firmware file content is modified by modifying the Firmware packaging mode, so that a method for integrally writing the Firmware file into Flash is avoided, and the problem of mirror image damage caused by long BMC upgrading time is reduced to the maximum extent. The specific method is that the Firmware file needs to be divided into regions according to content features and attributes, for example: the Firmware file may be divided into a header area and a predetermined number of content storage areas. The specific number of the content storage areas may be set by self-definition according to the content characteristics and attributes, and is not limited in this embodiment.
S102, reading identification information recorded in a file header area of a Firmware file;
specifically, after the Firmware file is divided into areas, when a script is packaged each time, modified content needs to be recorded in a file header area of the Firmware file, the modified content can be recorded through identification information, and the identification information can indicate which area content is not modified, which area content is modified, which content is specifically modified, a specific storage position of the modified content, and the like. Therefore, when the Firmware file is obtained and updated, the identification information recorded in the file header area of the Firmware file may be written first, for example: firstly writing the initial 1M content of the Firmware file so as to select a content storage area to be written in Flash according to the recorded identification information, directly positioning the content storage area according to the identification information, writing the modified data content in Flash, and upgrading the BMC.
In addition, the specific space size of the header area and each content storage area, and what content is stored in each content storage area can be set by user according to needs. Referring to fig. 2, a schematic diagram of a Firmware file region division structure disclosed in the present invention is shown; as can be seen from the figure, in the present application, the Firmware file is divided into six regions, which are: the method comprises the following steps of (1) a file header area, an uboot storage area, a kernel storage area, a file system storage area, a configuration file storage area and an application program storage area; wherein, the file header area can be set as 1M space for recording the change content; the uboot storage area is an uboot storage position, namely a uboot. The kernel storage area is a kernel storage position, namely a ui file, and occupies a size of 4M; the file system storage area is a file system storage position and occupies 5M of size; the configuration file storage area is the storage position of each configuration file and occupies 5M of size; the application storage area is a storage location of each application, and occupies a size of 16M.
S103, determining the modified data content of the Firmware file by using the identification information;
wherein the determining the modified data content of the Firmware file by using the identification information comprises: determining a target content storage area in which the data content is modified by using the area identification information; and determining the modified data content in the target content storage area by using the content identification information, and determining the storage position of the modified data content according to the position identification information.
It is understood that, in the present application, the identification information may include area identification information indicating which area has no modified content and which area has modified content, content identification information indicating which area has specifically modified content, and location identification information indicating a specific storage location of the modified content, where the location identification information may be index information from which modified data content of the Firmware file can be directly located, thereby achieving fast determination of the modified data content. Therefore, after the identification information recorded in the file header area is read, the modified data content can be quickly positioned from the Firmware file by using the identification information, so that the upgrading can be carried out through the content.
And S104, writing the modified data content into the BMC to upgrade the BMC.
Wherein the writing the modified data content to the BMC to upgrade the BMC includes: and writing the modified data content into the Flash of the BMC by using the position identification information so as to upgrade the BMC.
It should be noted that, after the modified data content of the Firmware file is determined by using the identification information, the location where the modified data needs to be erased and written in Flash of the BMC can be searched according to the location identification information in the identification information, so that the modified data content is correspondingly written in.
It can be seen that, according to the upgrading method disclosed by the application, after the Firmware file is subjected to region division, identification information can be added during Firmware packaging, during upgrading, a region needing to be refreshed can be selected according to the identification information recorded in the divided region of the Firmware file, and the part which does not need to be modified is kept unchanged, so that the upgrading efficiency is improved.
