In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a BMC upgrading method provided in the present application, where the BMC upgrading method includes:
s101: the upgrading image file of the BMC is written into the PCH Flash in a flashing mode;
specifically, an area for storing an upgrade image file of BMC is divided in PCH (platform memory controller Hub, an integrated south bridge of intel corporation) Flash in advance, when the BMC needs to be upgraded, the upgrade image file is firstly written into the PCH Flash through an in-band tool, the writing speed is improved, and meanwhile, the upgrade image file of the BMC does not need to be directly written into the BMC Flash, so that the BMC can normally operate, and the normal work of the BMC cannot be influenced.
S102: when the BMC is restarted, detecting whether an upgrade image file exists in the PCH Flash, if so, executing S103;
s103: and burning the upgrade image file into the BMC Flash so as to enable the BMC to be started through the upgrade image file.
It can be understood that there are various operating conditions that require BMC restart, and therefore, in this embodiment, in the process of BMC restart each time, it is detected whether an upgrade image file exists in PCH Flash, and if so, the upgrade image file is burned into BMC Flash, and the upgrade of BMC is completed in the process of BMC restart, so that BMC is started according to the upgrade image file. The whole upgrading process is asynchronous upgrading, and the BMC does not need to be forced to restart immediately, so that the external service of the BMC cannot be influenced.
As a preferred embodiment, before burning the upgrade image file into the BMC Flash, the BMC upgrade method further includes:
verifying the upgrade image file;
the process of burning the upgrade image file into the BMC Flash comprises the following steps:
and burning the successfully verified upgrade image file into the BMC Flash.
Specifically, in order to ensure the operation stability and the safety of the server, the upgrade image file needs to be checked, so that potential safety hazards caused by malicious tampering of the upgrade file are avoided, the checking mode can be md5 or hash, and the checking mode can be selected according to actual engineering requirements, which is not specifically limited herein.
Specifically, the upgrade image file which is successfully checked is burned into the BMC Flash, so that the BMC can be started through the upgrade image file, the upgrade image file which is failed in checking is discarded, and the BMC is still started according to the initial image file which is used before the upgrade image file is received.
As a preferred embodiment, before burning the upgrade image file into the BMC Flash, the BMC upgrade method further includes:
integrating the upgrade image files to obtain a target image file;
the process of burning the upgrade image file into the BMC Flash comprises the following steps:
and burning the target image file into the BMC Flash.
It can be understood that, in the present application, the upgrade image file is stored in the PCH Flash in advance, and in the process of restarting the BMC, the upgrade image file is detected to exist in the PCH Flash, and after the upgrade image file is acquired, the upgrade image file is integrated into a target image file meeting the storage requirement of the BMC Flash, and then the target image file is burned into the BMC Flash, so that the BMC is started according to the target image file to complete BMC upgrade.
In the application, it is considered that the PCH Flash can be originally accessed in-band, and therefore, an area, such as 32M, in which the upgrade image file of the BMC can be stored is divided in the PCH Flash. Under an OS (Operation System), the image file is updated and written into the PCH Flash, so that the normal use of BMC is not influenced, and the writing speed can be increased. When the BMC is restarted next time, the BMC reads the upgrade image file from the PCH Flash first, performs integrity check, and if the check is passed, the upgrade image file is flushed into the BMC Flash, thereby completing the upgrade. According to the method and the system, BMC can be upgraded quickly, the whole upgrading process is asynchronous upgrading, the BMC is not required to be forced to restart, integrity verification of the upgrade image file is added, and the safety is high.
