In step S13, the firmware that repaired the failure is updated according to the new main firmware.
And repairing the original main firmware with the firmware according to the new main firmware, namely the original standby firmware, and synchronizing the firmware with the fault according to the data stored in the new main firmware so as to finish the quick fault repair.
Two storage units are arranged in one storage control device, one firmware is stored respectively, and when the current main firmware fails to operate, the standby firmware is called to execute storage control, so that one storage control device can meet the requirement of dual backup of storage control, and the hardware cost is reduced.
As a technical solution, updating the main firmware according to an update instruction; whether the standby firmware is consistent with the main firmware is checked; and updating the backup firmware inconsistent with the main firmware according to the main firmware so as to make the backup firmware consistent with the main firmware.
When the firmware needs to be updated, the current main firmware is updated, and then the standby firmware is updated according to the data stored in the updated main firmware.
As a technical scheme, the standby firmware is updated according to an update instruction; taking the original standby firmware as a new main firmware and the original main firmware as a new standby firmware; and updating the new standby firmware according to the updating instruction.

As a technical solution, the updating and repairing the firmware with the failure according to the new main firmware includes: and taking the repaired firmware as new standby firmware.
After the original main firmware with the fault is repaired, the repaired original main firmware is used as a new standby firmware and is not switched back to the original main and standby firmware, so that the switching frequency and frequency of the system firmware are reduced, and the influence is reduced.
The present disclosure also provides a storage control apparatus, as shown in fig. 2, applied to a storage control device, where the storage control device includes a first storage unit and a second storage unit, and the first storage unit and the second storage unit respectively store firmware, and the apparatus includes: the control module 21 is configured to select one of the firmware stored in the first storage unit and the firmware stored in the second storage unit, use the selected firmware as a main firmware, and perform storage control, and use the unselected firmware as a backup firmware; a switching module 22, configured to, if the main firmware fails, use the standby firmware as a new main firmware to perform storage control; and the repair module 23 is configured to update and repair the failed firmware according to the new main firmware.
As a technical solution, updating the main firmware according to an update instruction; whether the standby firmware is consistent with the main firmware is checked; and updating the backup firmware inconsistent with the main firmware according to the main firmware so as to make the backup firmware consistent with the main firmware.

As a technical solution, the updating and repairing the firmware with the failure according to the new main firmware includes: and taking the repaired firmware as new standby firmware.
The firmware version information is stored in the SPI flash, so that double SPI flash is directly designed on a storage control card (storage control equipment), and double backup redundancy control can be realized on the firmware information.
Dual backup of storage firmware using dual SPI design
The hardware framework design is as shown in FIG. 3, and a single-card double-SPI flash structure is used for replacing the original double-raid design on hardware. The biggest difference between the design and the common array card is that the design of the main SPI flash and the standby SPI flash is made on the control chip. The SPI flash is actually the location where the storage control card firmware version information is stored.
After the server is provided with the storage control card, the system is installed by using the card, and after the system is installed. For the memory card, the memory control card firmware information is stored in the SPI flash, and the main SPI flash backs up this part of the information to the backup SPI flash. If the firmware state is found to be wrong in the running process of the storage service, the system can carry out data synchronization from the standby SPI flash and correct the current firmware state by using the firmware information in the standby SPI flash. At the moment, the standby SPI flash is switched to be a master from a standby state, the original master SPI flash is marked as standby, and meanwhile, firmware version information is synchronized from the existing master SPI flash, so that data consistency is finally realized.
When the consistency detection of the firmware version information exists on the software design matched with the memory card or the action of triggering the upgrading of the firmware exists, the synchronization requirement is triggered in an interruption mode. When the firmware information of the main SPI flash is changed, inconsistent information interruption can be triggered to the memory card firmware management system, and the management system can synchronize the information of the main SPI flash and the standby SPI flash for one time.
