Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, 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 only a part of the embodiments of the present application, 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 application.
For a better understanding of the present application, embodiments of the present application are explained in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for performing mirror image storage based on a CPLD according to an embodiment of the present application. As can be seen from fig. 1, the method for performing mirror image storage based on CPLD in this embodiment mainly includes the following processes:
s3: and refreshing the firmware version of the CPLD according to the acquired firmware loading command. Wherein, CPLD includes: a first mirrored storage area and a second mirrored storage area.
In this embodiment, two mirror image storage areas are fully utilized, the first mirror image storage area Compressed image1 is used as an active mirror image loading area, and the second mirror image storage area Compressed image0 is used as a standby mirror image storage area. Compressed image is a Compressed image.
The method for refreshing the firmware version of the CPLD in the embodiment comprises two methods: one is to refresh the firmware version of the CPLD in an I2C manner. And the other method is to refresh the firmware version of the CPLD in a GPIO mode.
Further, in this embodiment, step S3 is preceded by step S1: and the client logs in a BMC management interface of the server. And step S2: the firmware load command is sent by the BMC.
As can be seen from fig. 1, after the CPLD firmware version is refreshed, step S4 is executed: and judging whether the version of the CPLD firmware is qualified or not according to a return value in the refreshing result.
The return value is used for representing a firmware refreshing result, and whether the firmware version refreshing of the CPLD is qualified or not can be determined through the return value.
If the refresh is qualified, executing step S5: and loading a new CPLD firmware version from the first mirror image storage area.
That is, after the CPLD of the current version is successfully refreshed, the firmware data updating area of the CPLD refreshed by the user is the Compressed image1 area, and the new version of the CPLD is also loaded from the Compressed image1, but not from the Compressed image0.
S6: and determining the version of the CPLD firmware in the second image storage area according to the acquired firmware rollback command.
Specifically, step S6 includes the following processes:
s61: acquiring a firmware rollback command from the BMC, wherein the firmware rollback command comprises: perform rollback and not perform rollback.
The firmware rollback in this embodiment is: rollback.
S62: and if the firmware rollback command is to execute rollback, copying the data in the first mirror image storage area to a second mirror image storage area by using the CPLD, wherein the version of the CPLD firmware in the second mirror image storage area is a new version of the CPLD firmware.
S63: and if the firmware rollback command is that the rollback is not executed, keeping the version of the CPLD firmware in the second image storage area unchanged.
As can be seen from steps S61-S63, if the CPLD version is in the refresh successful state, it needs to further confirm whether to perform rollback, and then determine whether to update the firmware version of the CPLD in the second mirror storage area. Therefore, according to the method in this embodiment, the CPLD does not actively load the Compressed image0, nor actively update the data, so that two identical images caused by the active rollback can be avoided, and the space data of the image storage can be saved. In practical applications, the user can manually control whether the CPLD copies the data of the Compressed image1 to the Compressed image0 by issuing a command to the address of the standby image.
With continued reference to fig. 1, if the refresh is not qualified, step S7 is performed: and loading the spare CPLD firmware version from the second mirror image storage area.
That is, after the CPLD reads the refresh failure through its own relevant return value, the CPLD automatically loads the standby image of the Compressed image0 area. By adopting the method in the embodiment, the step S7 can ensure that the standby mirror image is available after the firmware is failed to refresh, thereby greatly improving the stability of the loaded mirror image of the CPLD. Through the step S62, timely update of the standby mirror image can be ensured, so that the CPLD version after the loading failure of the active mirror image is ensured to be correct, which is beneficial to improving the efficiency of mirror image storage.
Further, in the present embodiment, after steps S6 and S7, the process returns to re-execute step S1: and refreshing the firmware version of the CPLD according to the acquired firmware loading command. Namely, according to the acquired new firmware loading command, the firmware version of the CPLD is refreshed, so that the mirror storage of the next cycle is started.
The following describes in detail specific steps of the method for performing mirror image storage based on a CPLD in the present embodiment in practical application.
1) A user logs in a BMC management interface of the server;
2) A user selects system maintenance- > FirmWare updating- > uploading CPLD FirmWare;
3) After the refreshing is finished, the BMC automatically issues a command to trigger CPLD FirmWare reloading, and the CPLD takes effect;
4) If the CPLD fails to refresh, the CPLD reads that the refreshing fails through the self-related return value, and at the moment, the CPLD automatically loads the standby mirror image of the Compressed image0 area;
5) If the CPLD of the current version is successfully refreshed, the CPLD FirmWare data updating area refreshed by the user is a Compressed image1 area, and the new version of the CPLD is loaded from the Compressed image1 instead of the Compressed image0;
6) In the state of successful refresh, the CPLD will not actively load the Compressed image0 and will not actively update data, which is to avoid two identical images caused by the active rollback, if the CPLD actively performs the rollback, the existence of the standby image is meaningless, and at this time, the user issues a command to the address of the standby image, and the user manually controls whether to copy the data of the Compressed image1 to the Compressed image0.
In summary, by using the method of the embodiment, the situations that the RSU fails and the mirror image of the CPLD cannot be loaded normally due to some reasons can be effectively solved, and the CPLD of the server can be ensured to load a stable version for the temporary use of the client, so that the stability of the server operation is improved.
