In the technical scheme, a double-Flash scheme is adopted to ensure service operation, and the service operation is performed in a main partition called Flash1 and in a spare partition called Flash 2. When the Flash1 is damaged, the operation is automatically switched to the Flash2 by means of a register in the chip. According to the scheme, redundant Flash is used for achieving main and standby, corresponding Flash is selected through FWMSPICS, so that Flash1 cannot be accessed when Flash2 is operated, and firmware cannot be recovered by software re-erasing of Flash 1.
In view of the above, the present disclosure provides a firmware management method, apparatus, electronic device, and machine-readable storage medium, so as to improve the problem that the firmware abnormality affects the operation of the service.
The specific technical scheme is as follows.
In one embodiment, the present disclosure provides a firmware management method applied to a server including and including only one piece of hardware storage device for storing firmware, the method including: the method comprises the steps of maintaining interactive connection with a hardware storage device through an SPI interface, configuring a first storage area and a second storage area in the hardware storage device, storing main firmware in the first storage area, and storing reserved firmware in the second storage area; responding to an event of main firmware abnormality, reading the firmware stored in the second storage area through the currently maintained interactive connection with the hardware storage device and operating the firmware; and according to an abnormality recovery unit included in the standby firmware, the first storage area is refreshed to recover the abnormal main firmware.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, the interactive connection with the hardware storage device is kept through an SPI interface, a first storage area and a second storage area are configured in the hardware storage device, main firmware is stored in the first storage area, and reserved firmware is stored in the second storage area;
step S12, in response to an event of main firmware abnormality, reading the firmware stored in the second storage area through the currently maintained interactive connection with the hardware storage device and running;
step S13, according to an abnormality recovery unit included in the standby firmware, the first storage area is refreshed to recover the abnormal main firmware.
By configuring the storage area of the main firmware and the storage area of the standby firmware on the same hardware storage device, when the standby firmware is started due to the abnormality of the main firmware, the interaction connection with the hardware storage device where the main firmware is positioned can be still maintained through the SPI interface, so that the repair and the refreshing of the main firmware through software are realized.
In one embodiment, the method for refreshing the first storage area to restore the abnormal main firmware according to the abnormality restoring unit included in the spare firmware includes: detecting a non-abnormal flag bit, and if the non-abnormal flag bit is not marked, executing a step of refreshing a first storage area to restore abnormal main firmware according to an abnormal restoring unit included in the spare firmware; the non-exception flag bit is marked when the non-main firmware exception event cause selects to enter the standby firmware.
In one embodiment, the non-abnormal flag bit is used for being detected by the server when the server is started, so that the server responds to the event that the non-abnormal flag bit is marked when the server is started, and the interaction connection with the hardware storage device is maintained through the SPI interface, and the firmware of the second storage area is read and operated.
In one embodiment, the method for refreshing the first storage area to restore the abnormal main firmware according to the abnormality restoring unit included in the spare firmware includes: preferentially using the updated mirror image after stability verification to write the first storage area so as to recover the abnormal main firmware, and if the updated mirror image after stability verification does not exist, using the initial mirror image to write the first storage area so as to recover the abnormal main firmware; and the updated mirror image after the stability verification is a mirror image which is written into the second storage area after the stability verification is performed for a preset time period.
In one embodiment, a flash (hardware storage device) is used to implement the primary and secondary partitions, and after the primary and secondary partitions are switched to each other, the primary partition can still be accessed. The flash space is divided into two parts, namely a front half part is used as a main partition, and a rear half part is used as a standby partition. Under normal conditions, the BMC is started in the main partition, and the user can use the functions normally.
There are two sources of firmware for exception recovery: (1) a factory image, which is considered reliable, which is used when there is no updated image; (2) the user updated mirror image is uploaded when the user upgrades and can be obtained in places such as a official network. When a user upgrades, the image file upgraded at the time is saved, but the state of the image file just upgraded is unreliable, so that 10 minutes of observation time is set, and abnormal conditions such as BMC restarting and the like do not occur within 10 minutes, and the new firmware is used for recovering the firmware abnormally.
After the main partition is abnormal and enters the standby partition, the trusted abnormal recovery firmware is used for carrying out abnormal recovery, the main partition is refreshed again, and the original configuration is kept unchanged. After successful brushing, the main partition is automatically switched to complete the abnormal recovery.
In order to judge whether the main firmware of the main partition is abnormal to enter the spare partition, defining a non-abnormal flag bit, wherein the non-abnormal flag bit can be a flag file, if the flag bit is manually switched to the spare partition, the flag file is generated, and the abnormal recovery flow is not executed. If the exception is in the spare partition, the flag file is not available, the main firmware exception is considered to happen, if the exception recovery function is started, the latest recovery mirror image is acquired, and the main partition is started to be brushed. After the brushing is finished, the issuing command is switched to the main partition, and the main partition is restored to be normal.
The image source of the BIOS is only obtained by uploading by a user, and when the user successfully updates the new BIOS image and the BIOS can normally run in the new version, the BIOS image can be considered to be available and used as an abnormal recovery image. When the BIOS starts an exception, an interrupt is sent to the BMC application, and after the exception is received, an exception recovery process is started.
According to the technical scheme, the single flash double partition is realized, and the address of the main partition can be accessed when the spare partition runs.
In one embodiment, the present disclosure also provides a firmware management apparatus, as in fig. 2, applied to a server, where the server includes and only includes a piece of hardware storage device for storing firmware, the method includes: the first module is used for maintaining the interactive connection with the hardware storage device through the SPI interface, configuring a first storage area and a second storage area in the hardware storage device, storing main firmware in the first storage area, and storing reserved firmware in the second storage area; the second module is used for responding to the event of the abnormality of the main firmware, reading the standby firmware stored in the second storage area and running through the currently maintained interactive connection with the hardware storage device; and the third module is used for refreshing the first storage area according to an abnormality recovery unit included in the standby firmware so as to recover the abnormal main firmware.
In one embodiment, the method for refreshing the first storage area to restore the abnormal main firmware according to the abnormality restoring unit included in the spare firmware includes: detecting a non-abnormal flag bit, and if the non-abnormal flag bit is not marked, executing a step of refreshing a first storage area to restore abnormal main firmware according to an abnormal restoring unit included in the spare firmware; the non-exception flag bit is marked when the non-main firmware exception event cause selects to enter the standby firmware.
