Detailed Description
The core of the application is to provide a BMC starting method, a BMC starting device, a server and a computer readable storage medium, corresponding flash operation is executed on a first storage medium firstly, a firmware mirror image in a second storage medium is kept to operate, then BMC is started, when the starting is successful, the first storage medium is used for starting, and when the starting is unsuccessful, BMC starting operation is executed from the second storage medium, so that the problem that the BMC cannot be started due to programming failure is solved, and the reliability and the stability of the BMC are improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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.
In the prior art, there are three methods for upgrading dual BMC storage media: the memory medium of the BMC is required to be taken down by programming the mirror image through the burner; mirroring the serial brush into a storage medium in an NFS mounting mode; and refreshing BMC mirror image data through the network page. The latter two ways are more commonly used because the burning threshold is more difficult when the chip is removed, but in the latter two ways, occasionally, the situation that the BMC firmware data of the previous two storage media cannot be burned after being erased occurs, which results in that the BMC cannot be restarted because the boot path is erased. Therefore, no matter what starting mode is adopted in the prior art, the situation that the BMC cannot be normally started after being upgraded is possible, and the reliability and the stability of the BMC are reduced.
Therefore, the application provides a BMC starting method, which includes executing corresponding flash operation on a first storage medium, maintaining a firmware image in a second storage medium, starting BMC, starting through the first storage medium when starting is successful, and executing BMC starting operation from the second storage medium when starting is unsuccessful, so that the problem that the BMC cannot be started due to programming failure is solved, and reliability and stability of the BMC are improved.
A BMC boot method provided in the present application is described below with reference to a specific embodiment.
Referring to fig. 1, fig. 1 is a flowchart of a BMC starting method according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, performing firmware image flash operation on a first storage medium of the BMC, and marking a hardware upgrading identifier;
the step aims to perform firmware image flash operation on a first storage medium of the BMC and mark a hardware upgrading identifier. Namely, the normal firmware image flash operation is executed on the first storage medium in the BMC, so as to update the firmware data of the BMC.
Optionally, this step may include:
step 1, performing firmware image flash operation on a first storage medium of the BMC;
Step 2, when the firmware image flash operation is completed, marking the hardware upgrading identification as a successful identification;
and 3, when the firmware image flashing operation fails, marking the hardware upgrading identifier as a failure identifier.
It can be seen that this alternative is primarily illustrative of how a firmware image flash operation may be performed. Specifically, in this alternative, the firmware image flash operation is first performed on the first storage medium of the BMC. The executed firmware image flash operation can adopt the prior art to provide any kind of firmware image flash operation. Then, when the firmware image flash operation is completed, marking the hardware upgrading identification as a successful identification; and when the firmware image flash operation fails, marking the hardware upgrading identifier as a failure identifier.
S102, carrying out firmware image holding operation on a second storage medium of the BMC;
and on the basis of the S101, performing firmware image holding operation on a second storage medium of the BMC. I.e. keeping the original firmware image data stored in the second storage medium.
In the prior art, when firmware data is updated for a BMC with dual storage media, firmware data update operations are performed for both a first storage medium and a second storage medium. I.e. all data in the storage medium is subjected to a refresh operation. Therefore, when the refreshed firmware data is wrong and normal starting operation cannot be performed, the BMC thoroughly has a problem and cannot be started, so that normal BMC operation is influenced, and the reliability of the BMC is reduced.
Therefore, in this step, the firmware image holding operation is performed on the second storage medium of the BMC, so that the second storage medium holds and stores the firmware image data that is stably started before the firmware is updated. So that when the first storage medium fails to boot, the firmware image in the second storage medium is used for booting.
In this embodiment, the first storage medium refers to a master storage medium in the BMC device, and the second storage medium refers to a slave storage medium in the BMC device.
Optionally, this step may include:
step 1, judging whether firmware mirror image data which is the same as that before the flash of the first storage medium is stored in a second storage medium of the BMC; if yes, executing step 2; if not, executing the step 3;
step 2, judging to keep successful;
and 3, copying the firmware image data before the first storage medium is flushed to a second storage medium.
It can be seen that this alternative is intended to illustrate how the firmware image retention operation is performed on the second storage medium. In the alternative, firstly, whether the same firmware image data as that before the flash of the first storage medium is stored in the second storage medium of the BMC is judged; if so, judging that the storage is successful, namely storing firmware image data which can be normally started before the flash in the second storage medium; and if not, copying the firmware image data before the first storage medium is flushed to the second storage medium. Therefore, the alternative scheme can always keep the firmware image data which can be normally started before the first storage medium is flushed and stored in the second storage medium.
S103, when the BMC is started from the first storage medium, judging whether the hardware upgrading identifier is a successful identifier; if yes, executing S104; if not, executing S105;
on the basis of S102, this step is intended to determine whether the hardware upgrade flag is a successful flag when the BMC is started from the first storage medium. That is, when the BMC is started, it is determined whether the hardware upgrade flag of the first storage medium in the BMC is a successful flag. If yes, the firmware image data in the first storage medium can be normally started at the moment. If not, the firmware image data in the first storage medium has problems and cannot be normally started.
Therefore, the step mainly judges whether the firmware image data can be normally started, and also can execute the pre-starting operation on the firmware image data in the first storage medium, so as to judge whether the firmware image data can be normally started according to the operation result.
S104, starting the BMC from the first storage medium;
this step is intended to boot the BMC from the first storage medium. That is, the firmware image data in the first storage medium is correct data and can be used directly. Thus, the BMC may be booted from the first storage medium.
Optionally, this embodiment may further include:
When the BMC is started from the first storage medium, the firmware image data in the first storage medium is flushed into the second storage medium.
Therefore, in this alternative, when the first storage medium can be normally started, it is indicated that the firmware image data in the first storage medium is correct data, and then the data is flushed into the second storage medium, so as to complete the firmware flushing operation of the BMC.
And S105, executing the BMC starting operation from the second storage medium.
This step is intended to start the BMC from the second storage medium. That is, the firmware image data in the first storage medium cannot be normally started, and a start operation needs to be performed from the firmware image data in the second storage medium.
Optionally, this embodiment may further include:
when the BMC starting operation is executed from the second storage medium, the firmware image data in the second storage medium is written into the first storage medium in a flash mode.
It can be seen that the present alternative is primarily intended to illustrate that when the BMC is booted from the second storage medium, the firmware image data in the second storage medium is available and the firmware image data in the first storage medium is not available. Therefore, the firmware image data in the second storage medium is flash-written into the first storage medium, so that the BMC stores the normal firmware image data.
In summary, in this embodiment, the corresponding flash operation is executed on the first storage medium, the firmware image in the second storage medium is kept, then the BMC is started, the first storage medium is used for starting when the start is successful, and the BMC start operation is executed from the second storage medium when the start is unsuccessful, so that the problem that the boot cannot be performed due to the burn-in failure is avoided, and the reliability and the stability of the BMC are improved.
A BMC boot method provided in the present application is described below with reference to a specific embodiment.
In this embodiment, the method may include:
step 1, erasing the firmware image data of the main storage medium and reserving the firmware image data of the auxiliary storage medium.
And 2, brushing the latest firmware image data into a main storage medium, and marking an upgrading mark in hardware.
And 3, starting the BMC from the main storage medium and checking a hardware mark.
Step 4, if the upgrade fails, the slave storage medium is started through the watchdog, and the firmware image data of the slave storage medium is flushed into the master storage medium; and if the upgrade is successful, erasing the secondary storage medium, and flushing the firmware image data of the primary storage medium into the secondary storage medium.
It can be seen that, in this embodiment, the corresponding flash operation is executed on the first storage medium, the firmware image in the second storage medium is kept, then the BMC is started, the first storage medium is used for starting when the start is successful, and the BMC start operation is executed from the second storage medium when the start is unsuccessful, so that the problem that the boot cannot be performed due to the burn-in failure is avoided, and the reliability and the stability of the BMC are improved.
