Description
Technical Field
The present invention relates to the field of server maintenance, and in particular, to a method, an apparatus, a device, and a computer-readable storage medium for updating a BMC firmware.
Background
The bmc (baseboard Management controller), which is a core component in a server Management system defined by an IPMI (intelligent Platform Management interface) protocol, is Management software independent of the system, is based on an IPMI specification of an industry standard, and is used for performing operations such as remote Management, firmware upgrade, system monitoring, and the like on a server.
With the rapid development of computer technology, the monitoring and management service role of BMC (baseboard management controller) in the server is also getting bigger and higher, and the status in the server industry is getting higher, and the attack layer for BMC firmware is endless, and various attacks can cause BMC firmware to malfunction. Therefore, during the use of the server, no matter in the operation maintenance or development process, the situation that the BMC cannot be started cannot be avoided. In recent years, due to the influence of epidemic situations, remote office is also normalized, and at the moment, when the BMC firmware is crashed and cannot be recovered, the traditional recovery method is to log in a system operating system and update the operating system through system software, or to disassemble a Flash (memory chip) through a burner and put the Flash into a specific burner for burning. The two traditional methods have strong limitations, depend on an operating system, and the operating system has login authority and read-write authority, in an operation and maintenance time period, due to the consideration of system and data safety, a client usually does not allow the operation and maintenance to enter the operating system, and is more impossible to load burning software in the operating system, while a machine in a development stage usually does not have the operating system, even if the operating system is installed, the operating system may be in a shutdown state when the BMC is crashed, and cannot be started remotely, Flash is detached to be burned, and the burning is difficult to conform to the main basic tone of remote office, and the method is very dependent on human intervention. Or the backup mirror image is stored in the BMC or the machine in advance, and the backup mirror image is not flexible enough.
Therefore, in order to make up for the deficiency that the prior art cannot remotely upgrade and quickly recover the BMC firmware, it is important to provide a method for quickly, simply and flexibly recovering the BMC firmware.

and performing the step of flashing the information stored in the test BMC into the original BMC again.
Optionally, the BMC firmware updating method further includes:
counting the number of times of flashing the information stored in the test BMC into the original BMC;

Therefore, the original BMC is monitored through the method; judging whether the original BMC has a fault according to a monitoring result; when the original BMC fails, the information stored in the test BMC is flashed into the original BMC. Compared with the prior art that the OS is required to be logged in to the system to be updated through system software, or Flash is detached to be placed in a specific burner to be burned through the burner, the prior art depends on an operating system too much, in an operation and maintenance time period, due to the consideration of system and data safety, a customer usually does not allow the operation and maintenance to enter the operating system, and is more unlikely to install burning software in the operating system, while a machine in a development stage is usually not provided with the operating system, even if the operating system is installed, the operating system may be in a shutdown state when the BMC crashes, and cannot be remotely started, the Flash is detached to be burned, and the Flash is difficult to conform to the main debug of remote office, and the intervention of a person is too dependent. The BMC firmware updating method provided by the application can directly recover without manual intervention, does not depend on the damage condition of the BMC firmware at all, only monitors the original BMC, and directly writes the information stored in the test BMC into the original BMC when the original BMC is found to have a fault. Therefore, the method for updating the BMC firmware is more convenient and flexible.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a BMC firmware updating method according to an embodiment of the present invention. The method can comprise the following steps:
s100, monitoring an original BMC;
the embodiment does not limit the specific method for monitoring the original BMC, as long as the operating state of the original BMC can be monitored. For example, monitoring the original BMC by monitoring the BMC operation status fed back by a Host-CPU (Host central processing unit) in the Host; or monitoring the running state of the original BMC by monitoring the heartbeat of the original BMC, namely monitoring the original BMC by an indicator light, wherein when the indicator light flashes, the original BMC indicates that the heartbeat exists, no fault occurs in the original BMC at the moment, and when the indicator light is normally on, the heartbeat is not detected, and the original BMC fails at the moment.
S101, judging whether the original BMC has a fault according to a monitoring result;
in this embodiment, a specific means for determining whether the original BMC fails according to the monitoring result is not limited, and it is only required to determine whether the original BMC fails according to the monitoring result. For example, if a feedback message sent by the original BMC is not received after the dog feeding message is sent, the Host-CPU (Host central processing unit) determines that the original BMC has a fault, and then determines whether the original BMC has a fault by monitoring a result determined by the Host-CPU (Host central processing unit). Or monitoring the original BMC by monitoring the state of the indicator light, determining that the original BMC has no fault when the indicator light is monitored to be in a flashing state, and determining that the original BMC has a fault when the indicator light is monitored to be in a normally-on state; for example, when the status of the indicator light is monitored to be green light flashing, it is determined that the original BMC is not in fault, when the status of the indicator light is monitored to be green light, it is determined that the original BMC is in fault, and when the status of the indicator light is monitored to be red light, it is determined that the original BMC is in flashing.
S102, when the original BMC has a fault, the information stored in the test BMC is written into the original BMC in a flashing mode.
This embodiment does not limit the type of information stored in the test BMC as long as it can be flashed into the original BMC. For example, the information stored in the test BMC may be information before the original BMC fails; or the test BMC does not store any information, and the blank information is written into the original BMC in a flashing mode at the moment, namely the information stored in the original BMC is erased through the blank test BMC; or the information stored in the test BMC is information required for running the monitoring management service corresponding to the original BMC and is further written into the blank original BMC, namely the test BMC can write in the blank original BMC. The embodiment also does not limit the time for flashing the information stored in the test BMC to the original BMC, for example, when the original BMC fails, the state of flashing the information stored in the test BMC to the original BMC is automatically switched to, for example, when a flash instruction is received, the information stored in the test BMC is flashed to the original BMC. This embodiment does not define what should be done when the original BMC does not fail. For example, when the original BMC does not fail, performing flashing of information stored in the test BMC to the original BMC is prohibited; or when the original BMC is not in fault, executing some operations of remote management, firmware upgrade, system monitoring and the like of the original BMC on the server. In the implementation, after the information stored in the test BMC is flashed to the original BMC, the automatic reset of the original BMC can be realized, namely, the running state of the original BMC is automatically switched.
Based on the above embodiment, the embodiment of the present invention monitors the original BMC; judging whether the original BMC has a fault according to a monitoring result; when the original BMC fails, the information stored in the test BMC is flashed into the original BMC. Compared with the technical scheme that the Flash needs to be detached and placed in the specific burner for burning through the burner in the prior art, the Flash testing method and the Flash testing device only monitor the original BMC, when the original BMC is found to be in fault, the storage information in the tested BMC is written into the original BMC in a flashing mode, and therefore the original BMC can be recovered to a normal state as soon as possible. Therefore, the technical scheme provided by the embodiment of the invention can quickly restore the damaged original BMC firmware in time without manual intervention.
Based on the above embodiment, further to facilitate subsequent analysis of the reason that the original BMC firmware fails, when the original BMC fails, the method may further include:
and reading and storing the storage information of the original BMC.
The embodiment does not limit the location where the storage information of the original BMC is read and stored, as long as the storage information of the original BMC can be read and stored. The embodiment reads and stores the storage information of the original BMC when the original BMC fails, so that the reason for the failure of the original BMC is conveniently analyzed, the embodiment can facilitate problem analysis and positioning and development, operation and maintenance, and further avoid the failure of the original BMC again.
Based on the above embodiment, further in order to improve the success rate of the flashing, after the information stored in the test BMC is flashed to the original BMC, the method may further include:
obtaining the duration time after the flash is finished;
when the duration time exceeds a preset time threshold value, and the original BMC after the flashing cannot normally run;
and performing the step of flashing the information stored in the test BMC into the original BMC again.
The duration after the flashing is completed in this embodiment refers to the duration after the stored information is completely flashed to the original BMC by the test BMC. The embodiment does not limit the specific value of the preset time threshold, and the time required by the restart of the original BMC may be limited. For example, it may be 4 minutes, 5 minutes, 6 minutes, 7 minutes, or the like. In this embodiment, the specific time for determining the running state of the original BMC after the flash is not limited to the specific time after the preset time threshold. For example, if the original BMC after the flash is found to be incapable of operating normally after 5 minutes, the step of flashing the information stored in the test BMC to the original BMC needs to be continuously executed; or after the flash is finished for 4 minutes, if the original BMC after the flash cannot normally run, the step of writing the information stored in the test BMC into the original BMC needs to be continuously executed; or when a reset signal is received after the flashing is finished, detecting whether the original BMC after the flashing can normally operate or not after a preset time threshold value, and if the original BMC after the flashing can not normally operate and the flashing is not successful, executing the step of flashing the information stored in the test BMC into the original BMC again; or after the flash is finished, automatically resetting, and further detecting whether the original BMC after the flash can normally operate within a preset time threshold, wherein if the original BMC after the flash cannot normally operate, the flash is not successful, and the step of flashing the information stored in the test BMC into the original BMC needs to be executed again. This embodiment does not limit the operations that the original BMC after the flush may need to perform after the normal operation after the preset time threshold is exceeded. For example, when the original BMC after flashing exceeds the preset time threshold can normally operate, the prompt message is sent to prompt the user that the original BMC after flashing can be normally used, or no message is sent, and the corresponding operation executed when the original BMC does not fail is directly executed.
Based on the foregoing embodiment, further to prevent the problem that the original BMC cannot be restored by the flush, which results in the flush being always performed and affects the efficiency of restoring the original BMC firmware, the BMC firmware updating method may further include:
counting the number of times of flashing the information stored in the test BMC into the original BMC;
and when the number of times exceeds the preset flashing number of times, suspending the step of flashing the information stored in the tested BMC into the original BMC, and outputting prompt information which cannot be flashed normally.
In this embodiment, specific values of the preset number of times of flashing are not limited, for example, the preset number of times of flashing is 5 times, the preset number of times of flashing is 3 times, the preset number of times of flashing is 4 times, and the like. The embodiment also does not limit the specific type of the prompt message which cannot be normally swiped and output, and for example, the prompt message which cannot be normally swiped may be prompted in a text form, or the prompt message which cannot be normally swiped may be prompted in a vibration form, or the prompt message which cannot be normally swiped may be prompted in a voice form.
Based on the above embodiment, further to facilitate monitoring the operating state of the original BMC and to discover a fault in time, the monitoring the original BMC may include:
monitoring the original BMC through an indicator light;
when the indicator light flashes, the original BMC does not fail;
when the indicator light is normally on, the original BMC fails.
This embodiment does not limit the specific type of indicator light, for example, when the green light flashes, it represents that the original BMC is not malfunctioning, and when the green light is constantly on, it represents that the original BMC is malfunctioning. Or when the red light flashes, the original BMC is not in fault, and when the red light is normally on, the original BMC is in fault.
Based on the above embodiment, further to accelerate the rate of updating the original BMC by the logging test BMC, before monitoring the original BMC, the method may further include:
when a reading instruction is received, reading the original BMC;
and flashing the content in the original BMC into the test BMC.
In this embodiment, the specific content that is flashed to the test BMC is not limited, and the user may flash the content in the original BMC to the test BMC according to the user's needs.
Based on the above embodiment, further to timely and quickly find that the original BMC firmware has a problem, the monitoring the original BMC may include:
and monitoring the original BMC according to a preset period.
The embodiment does not limit the specific time of the preset period. Such as 1 second, 2 seconds, 3 seconds, etc.
In summary, based on the above embodiments, the BMC firmware updating method provided in the embodiments of the present invention can quickly and flexibly update the BMC firmware without manual intervention. In addition, according to the BMC firmware updating method provided by the embodiment, when the original BMC firmware fails, the storage information of the original BMC can be read and stored, so that the reason why the original BMC firmware fails is further conveniently and accurately analyzed; and when the time exceeds a preset time threshold, the original BMC after the flashing cannot normally run; and performing the step of flashing the information stored in the test BMC into the original BMC again. The situation that one-time flash writing can not be successfully performed is further prevented, and the success rate of flash writing is improved through multiple times of flash writing. Further, in this embodiment, the number of times of flashing the information stored in the test BMC to the original BMC is counted, and when the number of times exceeds the preset number of times of flashing, the step of flashing the information stored in the test BMC to the original BMC is suspended, and a prompt message that the flashing cannot be performed normally is output. The method prevents the fault of the original BMC from being solved by the brushing of the information stored in the tested BMC, so that endless brushing is caused, and the prompt information which cannot be brushed normally is output; and further this embodiment monitors the original BMC through indicator lights; when the indicator light flashes, the original BMC does not fail; when the indicator light is normally on, the original BMC goes wrong. By the method, the fault of the original BMC can be quickly and simply found; further, this embodiment reads the original BMC when receiving a read instruction; and flashing the content in the original BMC into the test BMC. Before the original BMC is updated by using the test BMC, the content in the original BMC is written into the test BMC in a flashing mode, so that the subsequent use of the test BMC for recovering the original BMC is more accurate and faster. Therefore, the BMC firmware updating method provided by the embodiment of the invention can be fast, simple and flexible, and can restore the original BMC without manual intervention.
