Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a method for upgrading a multi-level management system according to an embodiment of the present invention. The method for upgrading the multi-level management system includes:

Step S11: Obtain the images to be upgraded stored in all BMCs in the multi-level management system, and compare the images to be upgraded of the same type among the images to be upgraded stored in all BMCs to determine the target image to be upgraded with the highest version information in the same type;

Step S12: Send the target image to be upgraded to all BMCs, so that the target BMC can use the target image to be upgraded to upgrade;

Among them, the target BMC is any BMC in the multi-level management system.

In this embodiment, a method for upgrading a multi-level management system is provided. By using the method for upgrading a multi-level management system, any BMC can trigger the upgrade of the BMC that needs to be upgraded in the multi-level management system.

It should be noted that, in this embodiment, the CMC in the multi-level management system is used as the execution subject for description. Specifically, the CMC in the multi-level management system first obtains the images to be upgraded stored on all the BMCs in the multi-level management system. When the CMC obtains the images to be upgraded stored on all the BMCs in the multi-level management system, it then checks all the images to be upgraded. The images to be upgraded of the same type in the images to be upgraded stored in the BMC are compared to determine the target image to be upgraded with the highest version information among the images to be upgraded of the same type in the multi-level management system. Finally, when the CMC determines the version in the image to be upgraded When the target image with the highest information is to be upgraded, the CMC will send the target image to be upgraded to all BMCs under the control of the CMC for the target BMC that needs to be upgraded to be upgraded. That is, when the target BMC in the multi-level management system receives the target image to be upgraded sent by the CMC, the target BMC will use the target image to be upgraded to perform the upgrade.

Here, a specific example is used to illustrate. It is assumed that in a multi-level management system, the CMC controls 4 BMCs, that is, the CMC controls the BMCs on node A, node B, node C, and node D. When the multi-level management system needs to be upgraded, the CMC will first obtain the images to be upgraded stored in all BMCs in the multi-level management system, and add the images to be upgraded stored in node A, node B, node C, and node D. The images to be upgraded of the same type are compared to determine the target image to be upgraded with the highest version information among the nodes A, B, C, and D of the same type. If CMC finds that the version information of the target image to be upgraded in node A is higher than the version information of the image to be upgraded in node B, node C, and node D, in this case, it means that the version information of the image to be upgraded in node B, node C, and node D Upgraded images need to be upgraded. At this time, CMC will send the target image to be upgraded in node A to node B, node C, and node D. It is conceivable that when node B, node C, and node D receive the target image to be upgraded in node A, node B, node C, and node D can use the target image to be upgraded for upgrade.

Obviously, through such a setting method, it is equivalent to using any BMC under the control of CMC to trigger the upgrade of the BMC that needs to be upgraded in the multi-level management system, which avoids that the existing technology can only be upgraded through CMC. The defect of upgrading the BMC in the multi-level management system can significantly improve the user experience when upgrading the multi-level management system.

It can be seen that in this embodiment, the first step is to use the CMC in the multi-level management system to obtain the images to be upgraded stored in all BMCs in the multi-level management system, and perform the same type of images to be upgraded in the images to be upgraded stored in all BMCs. Compare to determine the target image to be upgraded with the highest version information in the same type; then, send the target image to be upgraded to all BMCs under the control of the CMC, so that the target BMC can use the target image to be upgraded to upgrade. Obviously, the upgrade method of the multi-level management system provided in this embodiment is equivalent to using any BMC under the control of the CMC to trigger the upgrade of the BMC that needs to be upgraded in the multi-level management system, thus avoiding the need to upgrade in the prior art. The defect that the BMC in the multi-level management system can only be upgraded through the CMC can significantly improve the user experience of the user when upgrading the multi-level management system.

Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation, the above-mentioned steps: the process of obtaining all the images to be upgraded stored by the BMC in the multi-level management system includes:

Obtain all the images to be upgraded stored in the BMC in the multi-level management system by polling.

Specifically, in this embodiment, CMC obtains the images to be upgraded stored in all BMCs in the multi-level management system by polling, because the polling operation is relatively simple and does not require designers to spend a lot of time writing Code, therefore, through this setting method, the control complexity of CMC can be relatively reduced.

In addition, in practical applications, all BMCs in the multi-level management system can also actively report their own operating information to the CMC, so that the CMC can be informed of the operating conditions of each BMC in time, so that the CMC can obtain multiple levels. The purpose of storing images to be upgraded in all BMCs in the management system.

Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation manner, the above-mentioned steps: the upgrade process of the target BMC using the target image to be upgraded includes:

When the target BMC receives the target image to be upgraded, it determines whether the version of the target image to be upgraded is higher than the version of the image to be upgraded running on the target BMC itself and the version of the image to be upgraded stored in the target BMC itself;

If yes, the target BMC itself is upgraded by using the target image to be upgraded.

In actual operation, it may happen that the target BMC stores the image to be upgraded, but the target BMC has not yet started running the image to be upgraded. Therefore, in this embodiment, when the target BMC receives the target image to be upgraded , The first step is to determine whether the version of the target image to be upgraded is higher than the version of the image to be upgraded running on the target BMC itself and the version of the image to be upgraded stored in the target BMC itself. If the version of the target image to be upgraded is higher than that of the target BMC itself The version of the image to be upgraded and the version of the image to be upgraded stored in itself indicate that the target BMC needs to be upgraded. At this time, the target BMC can use the target image to be upgraded for upgrade.

Obviously, through the technical solution provided by this embodiment, the erroneous upgrade phenomenon of the target BMC can be avoided.

Based on the foregoing embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation manner, the image to be upgraded includes an initial image of the image to be upgraded and a mirror head capable of characterizing the attributes of the image to be upgraded.

Obviously, in the actual operation process, the image type of the image to be upgraded is used to automatically identify the target device in the target BMC that needs to be upgraded when the image to be upgraded is upgraded, and the image version of the image to be upgraded is used to determine that the image to be upgraded needs to be upgraded during the upgrade. Whether the current running mirror version of the target device is consistent with the mirror version provided in the mirror to be upgraded.

It can be seen that the technical solution provided by this embodiment can further ensure the reliability of the image to be upgraded during the upgrade process.

When the target BMC receives the target image to be upgraded, it searches for the device to be upgraded in the target BMC according to the image header in the target image to be upgraded, and uses the target image to be upgraded to upgrade the device to be upgraded.

It is understandable that if the device to be upgraded in the target BMC is located in a different storage location, this may increase the time for the target BMC to find the device to be upgraded. Therefore, in this embodiment, the target BMC is using In the process of upgrading the target image to be upgraded, the first step is to find the device to be upgraded in the target BMC based on the image header in the target image to be upgraded. Because the image header of the target image to be upgraded contains the attributes of the image to be upgraded, so, When the target BMC receives the target image to be upgraded, it can find the device to be upgraded in the target BMC according to the image header in the target image to be upgraded, and use the target image to be upgraded to upgrade the device to be upgraded.

Obviously, through the technical solution provided in this embodiment, the search speed of the target BMC when searching for the device to be upgraded can be relatively improved.

As a preferred implementation manner, the above steps: the process of searching for the device to be upgraded in the target BMC according to the mirror header in the target image to be upgraded includes:

Programmable Logic Device) or PSU (Power Supply Unit) to be upgraded. Because BMC or BIOS or CPLD or PSU are relatively common devices in practical applications, the technical solution provided in this embodiment can be relatively Improve the universality in the process of upgrading the equipment to be upgraded in the target BMC.

Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation, the above-mentioned steps: before the process of obtaining all the images to be upgraded stored in the BMC in the multi-level management system, it also includes:

Specifically, in this embodiment, in order to improve the speed and efficiency of the CMC in obtaining the image to be upgraded from all BMCs in the multi-level management system, a preset image storage area is set in the target BMC in advance to store the image to be upgraded. Mirroring, that is, when the target BMC receives the image to be upgraded sent by the target user, the target BMC will store the image to be upgraded sent by the target user in the preset image storage area of the target BMC.

It is conceivable that when the image to be upgraded is stored through the preset image storage area set in the target BMC, the search time of the CMC when obtaining the image to be upgraded from the target BMC can be relatively shortened, thereby improving the CMC Obtain the speed and efficiency of the image to be upgraded from the multi-level management system.
