Detailed Description
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.
The embodiment of the application discloses a BMC dual-firmware mirror synchronization method, which is applied to a server and is shown in figure 1, and the method comprises the following steps:
step S11: a check is made to see if the primary firmware partition image of the working disk and the backup firmware partition image of the mirrored disk are complete in RAID 1.
In this embodiment, first, dual firmware (i.e., main firmware and standby firmware) of the BMC needs to be allocated to two disks (i.e., a working disk and a mirror disk) located in RAID1 (i.e., a disk mirror), and a mirror structure of the two disks of RAID1 after allocation is shown in fig. 2, where the two disks include firmware 1 (i.e., the main firmware) and firmware 2 (i.e., the standby firmware), firmware data in the firmware 1 and the firmware 2 are both stored in a partitioned manner, the firmware 1 is located in the working disk of RAID1, and the firmware 2 is located in the mirror disk of RAID 1. It will be appreciated that since firmware 2 is an image of firmware 1 as backup firmware, the partition present in firmware 1 is also present in firmware 2, as in firmware 1 located on a RAID1 working disk in fig. 2, which includes two logical partitions and two data partitions, firmware 2 located on a RAID1 image disk should include the same partition as firmware 1, i.e., the two logical partitions and the two data partitions.
It should be noted that, in general, the firmware of the BMC may be burned or upgraded into a flash (hard disk) through a burner or a WEB page of the BMC, which is equivalent to installing an operating system for the flash, and after the burning or upgrading is completed, various logic partitions and data partitions may be formed, where the flash partition of the BMC mainly includes: the boot partition is used for storing bootloaders (namely boot loaders) and belongs to the logic partition; the kernel partition is used for storing the Linux kernel and belongs to the logic partition; a rofs (read only file system) partition for storing necessary executable files, such as configuration files required by the Linux system, belongs to the logical partition; an rwfs-log partition belonging to the data partition (i.e., read write file system-log, log partition of a read-write file system); an rwfs-conf partition (a profile partition of a read-write file system) belonging to a data partition. Thus, logical partitions and data partitions located in the primary firmware partition image and the backup firmware partition image in RAID1 include, but are not limited to, boot partitions, kernel partitions, ROFS partitions, rwfs-log partitions, rwfs-conf partitions, and the like.
In this embodiment, after the dual firmware of the BMC is respectively allocated to the two disks located in RAID1, further, the integrity of the firmware partition images (i.e., the primary firmware partition image of the working disk and the backup firmware partition image of the mirror disk) located in the two disks of RAID1 is detected. In a particular embodiment, the integrity of the primary firmware partition image of the working disk and the backup firmware partition image of the mirrored disk located in RAID1 may be checked by the kernel portion.
In this embodiment, before detecting whether the primary firmware partition image of the working disk and the backup firmware partition image of the mirror disk in RAID1 are complete, the method specifically further includes: adding a target service program created based on the RAID1 in a main business logic service program of the BMC, and initializing a main firmware and a standby firmware of the BMC to be the RAID1 when the target service program is executed. Specifically, according to the application, firstly, a target service program needs to be created based on RAID1, the target service program is used for respectively allocating dual firmware of a BMC to two disks of RAID1, then the created target service program is added to a main business logic service program of the BMC, after an operating system is powered on, a U-Boot (i.e., a Universal Boot Loader for an embedded system) starts a watchdog, and starts to Boot a kernel of the BMC to start a whole BMC system, i.e., the main business logic service program, after the BMC system is successfully started, related monitoring management software and a WEB server are operated, the watchdog is fed, the target service program is created based on RAID1, and after the target service program is started, the dual firmware (i.e., main firmware and standby firmware) of the BMC is initialized to RAID 1.
Step S12: if the main firmware partition image of the working disk and the standby firmware partition image of the mirror disk in the RAID1 are complete, the BMC is started by calling the main firmware partition image, and target firmware data to be mirrored, which is generated in a normal operation process of the BMC, is acquired.
In this embodiment, if the main firmware partition image of the working disk in RAID1 and the standby firmware partition image of the mirroring disk are complete, that is, the partition image data of the main firmware and the standby firmware in the two disks of RAID1 are complete, the BMC may be further started by calling a logic partition in the main firmware partition image, and then target firmware data to be mirrored, which is generated by the BMC in a normal operation process, is acquired.
In a specific embodiment, the obtaining target firmware data to be mirrored, which is generated in a normal operation process of the BMC, may specifically include: and acquiring a configuration file and log information generated in the normal operation process of the BMC, and taking the configuration file and the log information as target firmware data to be mirrored. In this embodiment, after the BMC is started by calling the logical partition in the main firmware partition image, log information generated by the BMC in a normal operation process and a configuration file generated by user modification configuration may be further collected, and the collected log information and the collected configuration file are used as target firmware data to be mirrored.
Step S13: and storing the target firmware data into a standby firmware partition of the mirror disk according to a partition mirror image mode.
In this embodiment, after target firmware data to be mirrored, which is generated during the normal operation of the BMC, is acquired, the target firmware data is stored in a standby firmware partition of the mirror disk in a partition mirroring manner. For example, in the normal operation process of the BMC, if a user modifies the configuration of the firmware 1 in fig. 2, the configuration file generated after modification is stored in the data partition 1, and the partition corresponding to the firmware 2 is also modified correspondingly, that is, the configuration file is added to the data partition 1 of the firmware 2.
Further, the BMC dual firmware image synchronization method may further include: when the BMC needs firmware upgrading, one disk is randomly selected from the working disk and the mirror image disk to serve as a target disk, and the other disk serves as a disk to be upgraded; upgrading the firmware in the target disk to obtain upgraded firmware, and setting a flag bit with synchronous all partitions in the upgraded firmware; when the updated firmware is executed by the BMC, storing all partition images of the updated firmware in the target disk to the disk to be updated. In this embodiment, when the dual firmware in the BMC needs to be upgraded, in order to reduce the upgrade time, one disk may be randomly selected from a working disk and a mirror disk of RAID1 as a target disk, the other disk is used as a disk to be upgraded, then the firmware in the target disk is upgraded to obtain an upgraded firmware, that is, only one firmware of the BMC is upgraded, then a flag bit for synchronizing all partitions is set in the upgraded firmware, and when the BMC executes the upgraded firmware, it is found that the flag bit for synchronizing all partitions exists in the upgraded firmware, then all partitions of the upgraded firmware in the target disk are mirror-stored in the disk to be upgraded, that is, both the two pieces of firmware in the BMC are upgraded.
It can be seen that, in the embodiment of the present application, it is first detected whether a main firmware partition mirror image of a working disk located in RAID1 and a standby firmware partition mirror image of a mirror disk are complete, and if the main firmware partition mirror image of the working disk located in RAID1 and the standby firmware partition mirror image of the mirror disk are complete, a BMC is started by calling the main firmware partition mirror image, target firmware data to be mirrored generated in a normal operation process of the BMC is acquired, and then the target firmware data is stored in the standby firmware partition of the mirror disk in a partition mirror image manner. Therefore, according to the embodiment of the application, the BMC dual-firmware mirror image data are stored in a partitioned mode through the two disks in the RAID1, the completeness and the synchronization of the BMC dual-firmware mirror image data can be guaranteed, and the stability of the server BMC is improved.
The embodiment of the application discloses a specific method for synchronizing dual firmware images of a BMC (baseboard management controller), which is shown in fig. 3 and comprises the following steps:
step S21: a check is made to see if the primary firmware partition image of the working disk and the backup firmware partition image of the mirrored disk are complete in RAID 1.
Step S22: if the primary firmware partition image of the working disk and the backup firmware partition image of the mirror disk in the RAID1 are incomplete, determining whether the primary firmware partition image or the backup firmware partition image is complete.
In this embodiment, if the primary firmware partition image of the working disk and the backup firmware partition image of the mirror disk in RAID1 are incomplete, the integrity of the primary firmware partition image and the integrity of the backup firmware partition image are respectively determined.
In this embodiment, the method for synchronizing dual firmware images of a BMC may further include: executing the target service program, judging whether the U-Boot is started within preset time, if not, setting a mirror image starting failure zone bit in the target service program, and executing the step of judging whether the main firmware partition mirror image or the standby firmware partition mirror image is complete. Specifically, after executing a target service program created based on RAID1, if the U-Boot is not started within a preset time, if the U-Boot is not started within 5 minutes, that is, if the U-Boot does not successfully feed a dog to the watchdog of the U-Boot, it indicates that at least one of the main firmware partition image and the spare firmware partition image is incomplete, and the U-Boot sets an image start failure flag bit in the target service program, and then executes the step of determining whether the main firmware partition image or the spare firmware partition image is complete, that is, determines whether there is a complete firmware partition image capable of starting the BMC in two disks of RAID 1.
Step S23: and if the primary firmware partition mirror image or the standby firmware partition mirror image is complete, taking the complete partition mirror image as a target partition mirror image, and taking the other partition mirror image as an incomplete partition mirror image.
In this embodiment, if a complete partition image exists in the primary firmware partition image and the backup firmware partition image, the complete partition image is used as a target partition image, and the other partition image is used as an incomplete partition image.
Step S24: and recovering the logical partition image of the incomplete partition image by using the logical partition image of the target partition image, and starting the BMC by using the logical partition image of the target partition image.
In this embodiment, if the primary firmware partition image or the backup firmware partition image is complete, the complete partition image is used as a target partition image, and another partition image is used as an incomplete partition image, and further, the logical partition image of the incomplete partition image may be recovered by using the logical partition image of the target partition image, that is, the incomplete partition image is recovered by using the complete partition image, and then the BMC is started by using the logical partition image of the target partition image.
Step S25: and acquiring firmware data to be mirrored, which is generated in the normal running process of the BMC and is started by using the logical partition mirror image of the target partition mirror image, and mirroring the firmware data partition to be mirrored to the data partition of the incomplete partition mirror image.
In this embodiment, after the BMC is started by using the logical partition image of the target partition image, firmware data to be mirrored, which is generated in a normal operation process when the BMC is started by using the logical partition image of the target partition image, is acquired, and the firmware data to be mirrored is stored in the data partition of the incomplete partition image in a partition image manner. The firmware data to be mirrored includes, but is not limited to, configuration files, log information and other data.
In this embodiment, after mirroring the firmware data partition to be mirrored to the data partition of the incomplete partition mirroring, the method further includes: and clearing the mirror image starting failure flag bit in the target service program. It is understood that, in order to improve the utilization rate of RAID1 disk resources, the image start failure flag bit in the target service program may be deleted after the incomplete partition image is restored by using the complete partition image.
For a more specific processing procedure of the step S21, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.
It can be seen that, in the embodiment of the present application, when it is detected that the primary firmware partition image and the backup firmware partition image located in RAID1 are incomplete, it is further determined whether the primary firmware partition image or the backup firmware partition image is complete, and if there is a complete partition image, the logical partition image of the incomplete partition image is recovered by using the logical partition image of the complete partition image, and the firmware data image to be mirrored, which is generated in the normal operation process of the BMC, is stored in the data partition of the incomplete partition image. Therefore, according to the embodiment of the application, the two disks in the RAID1 are used for respectively storing the BMC dual firmware image data in a partitioned manner, a logical partition with a problem can be automatically repaired, and integrity and synchronization of the BMC dual firmware image data are guaranteed.
Correspondingly, an embodiment of the present application further discloses a BMC dual firmware image synchronization device, which is applied to a server, and as shown in fig. 4, the device includes:
the image detection module 11 is configured to detect whether a primary firmware partition image of a working disk and a backup firmware partition image of a mirror disk in RAID1 are complete;

and a data storage module 13, configured to store the target firmware data in a spare firmware partition of the mirror disk according to a partition mirror manner.
