Platform management represents a series of monitoring and control functions, the object of operation being the system hardware. Such as by monitoring the temperature, voltage, fans, power supplies, etc. of the system and making corresponding adjustments to ensure that the system is in a healthy state.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Example 1
The embodiment 1 of the application creatively provides a safe starting method of a baseboard management controller, adopts a double-mirror design mode, and provides an abnormal mirror image self-recovery mechanism and an escape upgrading means while ensuring that a standby mirror image can be started when the mirror image is started abnormally through a hardware timeout mechanism, and multiple strategies jointly ensure that the BMC mirror image can still be recovered to be normal when the BMC mirror image is illegally tampered or destroyed.
(1) Dual mirror switching mechanism
The BMC image contains three parts, U-boot, kernel (kernel) and file system. The U-boot is a mirror image bootstrap program, and when the U-boot starts normal booting, the watchdog timing function of the BMCAspeed chip is started, and the function of the watchdog is a time countdown counter. For example, the watchdog timeout time is 60 seconds, the U-boot starts the boot image program to start timing, if the kernel information is not successfully booted within 60 seconds, the watchdog will not close and timeout. The BMCAspeed chip is set to switch the spi interface to the standby flash information by overtime action, namely, the flash is started continuously from the standby flash, so that the double-mirror image switching logic is realized.
In addition, if the U-boot successfully guides the kernel information, the kernel starting program can update the watchdog timeout time again, namely, the kernel starting process timeout time is set, so that the problem that the starting process is blocked and the mirror image cannot be switched due to the fact that information systems such as kernel panic and the like appear in the kernel starting process is avoided.
The exception of any step in the mirror image starting process is ensured through the time-out mechanism limitation of the U-boot process and the kernel process, and the mirror image switching mechanism can be triggered.
(2) Mirror image anomaly recovery mechanism
The BMC can be started from the master image under normal conditions, but when the master image is started abnormally, an image switching mechanism is started, and if the standby image can be started normally, the starting process is completed by the standby image. After the starting is finished, the BMC performs self-checking according to the expected chip register, detects the starting time of the current mirror image, whether the mirror image is started overtime or not and the like, and determines that the starting main mirror image is in an abnormal state once the starting time is found to exceed the expected time of normal starting and the mirror image starting sequence is not manually switched, so that the starting main mirror image needs to be recovered immediately, and the problem that the starting time is overlong due to the fact that the mirror image switching mechanism is started again in the next starting is avoided.
The specific implementation process of the BMC main image recovery mechanism is as follows:
the BMC starts from the standby mirror image at the time, firstly, performs all erasing actions on the flash memory (flash) information of the main mirror image, then, copies and stores the standby mirror image content to a/var/log directory through a dd command, and independently stores the configuration related partition; and finally, the copy mirror image and the configuration information are written into the main mirror image flash chip according to the partition position again.
(3) The escape method comprises the following steps: BMC for upgrading U-boot
The two strategies can cope with the situation that the main image cannot be started due to abnormality, but the standby image can be started normally; if the standby mirror image is not started, the BMC can not be updated and recovered on line, the BMC chip can only be taken down from the main board, and the BMC chip can be refreshed off line by using the burner, so that a large amount of manpower and material resources are wasted. Therefore, the escape method for upgrading the BMC by the U-boot can trigger the recovery strategy of the U-boot image of the standby image even if the standby image cannot be started.
Firstly, a U-boot part in a BMC image is burnt on a flash chip protection partition, namely, no matter how the image is damaged, a U-boot starting program is not affected. When the primary image fails to start and the standby image also fails to start, the specific implementation steps are as follows:
1. starting the main mirror image, triggering a mirror image switching mechanism to switch to the standby mirror image for starting due to abnormal mirror images;
2. the standby image continues to start, but the image is also abnormal, cannot start normally, and triggers an image switching mechanism, so that the system tries to start from the main image again.
3. The master image is started again, the U-boot startup procedure detects the expected register information in the startup process, and the backup image can be judged to be unable to be started normally by finding the image switching mechanism triggered by the two times of watchdog overtime.
4. The master image U-boot triggers an image recovery mechanism, the BMC image can be loaded into BMC memory information through tftp, and then the U-boot guides the BMC image loaded in the memory, but not the abnormal image which cannot be started in the master flash chip. After the memory image is successfully guided, the BMC self-checking process can find out multiple image starting failure information so as to trigger an image abnormal recovery mechanism.
5. When the mirror image exception recovery mechanism is triggered, the BMC is started from the main mirror image position at the moment, but the mirror image in the main flash machine chip is not loaded, but the mirror image is loaded into the memory in a common file transfer protocol mode. A common file transfer protocol (TrivialFileTransferProtocol, TFTP) is used to provide the boot image for the client. Theoretically, any server, on any platform, can be used as long as these protocols are implemented. Therefore, when the abnormal image recovery mechanism is triggered, the standby image of the BMC is erased and rewritten. After the mirror image recovery is completed, the standby mirror image is recovered to be normal, and an abnormal mirror image recovery mechanism is started for the main mirror image when the standby mirror image is started next time.
In summary, the present embodiment has the following main contents:
(1) Switching between two physical Flash through WATCHDOG timeout mechanism; even if any FLASH image content is completely destroyed, another standby image can ensure the normal starting of the BMC, and the problem that the BMC cannot be started under the serious destruction condition that a single FLASH is erased and the like is solved.
(2) By the mirror image recovery mechanism, when the problem that the FLASH fails in mirror image starting is perceived, the abnormal mirror image can be automatically recovered, and the problem of abnormal starting of the mirror image is solved when the FLASH is started next time.
(3) And reserving a U-boot upgrading escape means, wherein even if two physical FLASH are verified and destroyed and cannot be started, the U-boot program on the partition can be protected, the network is used for guiding the image to start in a tftp mode, and after the image is started, the user can start.
In the safe starting method of the baseboard management controller, a double-mirror design mode is adopted, the standby mirror image can be started when the mirror image is started abnormally through a hardware timeout mechanism, an abnormal mirror image self-recovery mechanism and an escape upgrading means are provided, multiple strategies jointly ensure that the mirror image can still be recovered to be normal when the mirror image is illegally tampered or destroyed, the safe starting of the baseboard management controller is ensured, the mirror image recovery can be realized under the condition that the single mirror image or the double mirror images are abnormal, and the debugging efficiency and the product stability in the research and development process are greatly improved.
Example 2
The method for safely starting the baseboard management controller can be applied to an application environment shown in figure 1. The master mirror image flash memory chip 1 and the backup mirror image flash memory chip 2 are respectively written with the master mirror image and the backup mirror image, the master mirror image and the backup mirror image can both start the baseboard management controller 3 (BMC), the baseboard management controller 3 (BMC) is a chip, in addition, a guide image can be provided for the baseboard management controller 3 (BMC) through a common file transfer protocol (TrivialFileTransferProtocol, TFTP), the guide image is a memory mirror image, and the guide image is stored in the guide memory 4, and is not the master mirror image and the backup mirror image stored in the master mirror image flash memory chip 1 and the backup mirror image flash memory chip 2.
In one embodiment, as shown in fig. 2, a method for safely starting a baseboard management controller is provided, and the method is applied to the structure in fig. 1 for illustration, and includes the following steps:
step S1, setting a main mirror image and a backup mirror image for starting a baseboard management controller;
step S2, when the baseboard management controller is started, starting the baseboard management controller by adopting the main mirror image;
step S3, when the time for starting the baseboard management controller by adopting the main mirror image exceeds the first time, starting the baseboard management controller by adopting the backup mirror image;
and S4, after the backup mirror image is adopted to start the baseboard management controller, checking whether the main mirror image is abnormal, and if so, setting that the time for starting the baseboard management controller by adopting the main mirror image exceeds a second time without starting the baseboard management controller, wherein the second time is smaller than the first time, and starting the baseboard management controller by adopting the backup mirror image.
By setting the second time length smaller than the first time length, the application can enable the backup mirror image to be recovered immediately in the process of starting the baseboard management controller when the primary mirror image is abnormal, and avoid overlong starting time caused by starting the mirror image switching mechanism again in the next starting.
As shown in fig. 3, in this embodiment, the steps of setting the primary mirror and the backup mirror for the baseboard management controller to start include:
step S11, setting a master image and a backup image to comprise an image bootstrap program, a kernel and a file system;
step S12, writing the master image and the backup image into the master image flash memory chip and the backup image flash memory chip respectively;
step S13, when the baseboard management controller is started, the mirror image guiding program guides the kernel to start the baseboard management controller, and a countdown counter in the baseboard management controller is started to count the time for starting the baseboard management controller by adopting the main mirror image.
The time countdown counter is a watchdog timing function of the BMCAspeed chip, for example, the watchdog timeout time is 60 seconds, the U-boot starts the boot mirror program to start timing, and if the kernel information is not successfully booted within 60 seconds, the watchdog cannot be closed and times out. The BMCAspeed chip is set to switch the spi interface to the standby flash information by overtime action, namely, the flash is started continuously from the standby flash, so that the double-mirror image switching logic is realized.
In this embodiment, after the backup image is adopted to start the baseboard management controller, if the master image is checked to be abnormal, the method further includes:
And deleting the master image and storing the backup image copy as a new master image.
By deleting the master image and storing the backup image copy as a new master image, when the starting abnormality of the master image occurs, an image switching mechanism is started, and if the standby image can be started normally, the standby image covers the master image to realize BMC master image recovery.
As shown in fig. 4, in this embodiment, the step of deleting the primary image and saving the backup image copy as a new primary image includes:
step S41, obtaining the storage position of the main mirror image in the main mirror image flash memory chip;
step S42, deleting the master mirror stored in the master mirror flash memory chip;
in step S43, the backup image is copied to the storage location of the flash memory chip of the primary image and stored as a new primary image.
Specifically, the BMC starts from the standby mirror image, firstly performs all erasing actions on flash memory (flash) information of the main mirror image, then performs mirror image copying and storing to a/var/log directory through dd command on the standby mirror image content, and independently stores the configuration related partition; and finally, the copy mirror image and the configuration information are written into the main mirror image flash chip according to the partition position again. The way to save the backup image copy as a new master image is very convenient.
As shown in fig. 2, in this embodiment, the method further includes:
step S5, in response to the fact that the time length of starting the baseboard management controller by the master mirror image exceeds the first time length, and when the time length of starting the baseboard management controller by the backup mirror image exceeds the first time length, starting the baseboard management controller by the master mirror image and the backup mirror image again;
and S6, in response to the total times of starting the baseboard management controller by adopting the master mirror image and the backup mirror image being larger than a first threshold value, starting the baseboard management controller by adopting the network boot memory mirror image in a common file transfer protocol mode.
The method is to reserve a U-boot upgrading escape means, even if two physical FLASH are verified and destroyed and cannot be started, the U-boot program on the partition can be protected, the network is used for guiding the image to start in a tftp mode, and after the image is started.
It can be understood that the application can not only adopt the network boot memory mirror image of the common file transfer protocol (tftp) mode to start the baseboard management controller, but also adopt remote control to upgrade the main mirror image and the backup mirror image for starting the baseboard management controller at the same time, and can also upgrade the main mirror image and the backup mirror image for starting the baseboard management controller at the same time in an external U-disk mode, thus being capable of directly covering the main mirror image and the backup mirror image which are destroyed to generate errors and increasing the reliability of the system.
As shown in fig. 5, in this embodiment, the step of booting the memory mirror to start the baseboard management controller through the network in the normal file transfer protocol manner includes:
step S61, loading the memory mirror image in a common file transfer protocol mode;
step S62, deleting the backup image, and storing the memory image copy as a new backup image;
in step S63, the baseboard management controller is started up by using the new backup image.
The master image U-boot triggers an image recovery mechanism, the BMC image can be loaded into BMC memory information through tftp, and then the U-boot guides the BMC image loaded in the memory, but not the abnormal image which cannot be started in the master flash chip. After the memory image is successfully guided, the BMC self-checking process can find out multiple image starting failure information so as to trigger an image abnormal recovery mechanism.
As shown in fig. 2, in this embodiment, when the total number of times of starting the baseboard management controller by using the primary mirror and the backup mirror is greater than the first threshold, the step of starting the baseboard management controller by booting the memory mirror through the network in the normal file transfer protocol manner further includes:
Step S7, after the baseboard management controller is started by adopting the new backup mirror image, the baseboard management controller is controlled to restart;
and S8, deleting the master image and saving the new backup image copy as a new master image when the master image is checked to be abnormal in the restarting process of the baseboard management controller.
When the mirror image exception recovery mechanism is triggered, the BMC is started from the main mirror image position at the moment, but the mirror image in the main flash machine chip is not loaded, but the mirror image is loaded into the memory in a common file transfer protocol mode. A common file transfer protocol (Trivial File Transfer Protocol, TFTP) is used to provide the boot image for the client. Theoretically, any server, on any platform, can be used as long as these protocols are implemented. Therefore, when the abnormal image recovery mechanism is triggered, the standby image of the BMC is erased and rewritten. After the mirror image recovery is completed, the standby mirror image is recovered to be normal, and an abnormal mirror image recovery mechanism is started for the main mirror image when the standby mirror image is started next time. After the backup image is updated, the backup image is started again, the main image is automatically deleted, and a new backup image copy is stored as a new main image, so that the simultaneous updating of the main image is avoided.
In the safe starting method of the baseboard management controller, a double-mirror design mode is adopted, the standby mirror image can be started when the mirror image is started abnormally through a hardware timeout mechanism, an abnormal mirror image self-recovery mechanism and an escape upgrading means are provided, multiple strategies jointly ensure that the mirror image can still be recovered to be normal when the mirror image is illegally tampered or destroyed, the safe starting of the baseboard management controller is ensured, the mirror image recovery can be realized under the condition that the single mirror image or the double mirror images are abnormal, and the debugging efficiency and the product stability in the research and development process are greatly improved.
