Aiming at the defects of lower test efficiency, certain damage to a sensor and the like when the sensor faults are subjected to simulation test in the related technology, the application provides a sensor fault injection method, a device, a server and a storage medium.

The present application will be described below with reference to fig. 1 to 5 by taking an example in which the execution subject is a sensor fault injection device. It should be noted that, the sensor fault injection method provided by the present application is applied to a server, where the server includes: the BMC comprises a sensor monitoring module, wherein the sensor monitoring module is used for carrying out alarm judgment on sensor readings reported by the FRU modules.
Fig. 1 is a flow chart of a sensor fault injection method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps: step 110, step 120, step 130 and step 140. The method flow steps are only one possible implementation of the application. The method comprises the following steps:
step 110, receiving a fault injection instruction issued by a user through an external interface provided by the BMC;
it can be understood that the external interface provided by the BMC refers to an interface of the FRU module that needs to inject the fault.
In the specific implementation, when the simulation test is carried out on the sensor faults, the fault injection instruction issued by the user is received through the external interface provided by the BMC.
Step 120, judging the current working mode of the BMC;
further, after receiving the fault injection instruction issued by the user, the current working mode of the BMC needs to be judged at the interface layer.
In general, the operation mode of the BMC is classified into a non-test mode and a test mode. The non-test mode is mainly used in a normal operation mode, in which the actual reading of the sensor is taken, without supporting fault injection of any instructions. The test mode is mainly used for simulating the scene of the abnormal state, and because the fault injection of the sensor is mainly used for functional test verification such as sensor alarm and the like, namely, the fault injection of the target FRU module is only supported under the condition that the current working mode of the BMC is the test mode. Therefore, before fault injection is set, a determination needs to be made as to the current operation mode of the BMC.
Step 130, judging whether the target FRU module corresponding to the fault injection instruction is a shared device or not under the condition that the current working mode of the BMC is a test mode;
it is understood that the target FRU module refers to an FRU module that requires injection of a fault.
Further, in the case that the current working mode of the BMC is a test mode, it is required to determine a sharing attribute of the target FRU module corresponding to the fault injection instruction, where the sharing attribute of the FRU module includes a sharing device and a non-sharing device. And executing step 140 under the condition that the target FRU module corresponding to the fault injection instruction is a shared device.
For the sharing attribute of the target FRU module is a sharing device, because the design condition of the corresponding FRU module only acquires data information on the master controller and then synchronizes the data information to the slave controller, when the sharing device simulates a fault condition, fault injection is needed to be realized on the master controller through the flag bit, the data information is reported to the sensor monitoring module, and faults can be effectively injected, so that the sharing device only supports fault injection on the master controller.
For the sharing attribute of the target FRU module, the corresponding FRU module respectively reads the temperature of the sensor on each controller and then synchronizes the data information to other modules, so that fault injection on any controller can be supported for the non-sharing device.

Further, the fault injection interface of the target FRU module is called to transmit the fault injection instruction to the target FRU module, and the fault marking bit of the target FRU module is set to be in a setting state, so that the fault injection sensor is implemented in a software mode.
In the embodiment of the application, the fault injection instruction issued by the user is received through the external interface provided by the BMC; judging the current working mode of the BMC; judging whether a target FRU module corresponding to the fault injection instruction is a shared device or not under the condition that the current working mode of the BMC is a test mode; and under the condition that the target FRU module corresponding to the fault injection instruction is a shared device, determining a master-slave state of a controller in the target FRU module, and under the condition that the master-slave state of the controller in the target FRU module is dominant, calling a fault injection interface of the target FRU module to transmit the fault injection instruction to the target FRU module, and setting a fault flag bit of the target FRU module to be in a set state. According to the application, the fault is injected into the sensor in a software mode, so that the fault testing efficiency of the analog sensor can be improved, and meanwhile, the damage to the sensor can be reduced.
In some embodiments, the method further comprises:
and under the condition that the target FRU module detects that the current working mode of the BMC is a test mode and the fault marking position of the target FRU module is in a set state, acquiring the reading of a corresponding sensor through the target FRU module, setting the reading of the sensor as an invalid value, and reporting the reading of the sensor to the sensor monitoring module.
It should be noted that, the sensor fault injection method provided by the application is suitable for the FRU module sensor for independently acquiring the temperature, specifically, the FRU module sensor for independently acquiring the temperature generates a sensor number through the architecture configuration catalog definition file, accesses hardware in the corresponding FRU module to realize the physical scanning of the relevant temperature, provides a temperature reading interface for the sensor monitoring module after the temperature point is acquired, and is used for the sensor monitoring module to be connected with a hook to realize the management and alarm judgment of the sensor reading.
In a specific implementation, when the target FRU module detects that the current working mode of the BMC is a test mode and the fault marking position of the target FRU module is in a set state, the target FRU module is used for collecting the corresponding reading of the sensor, setting the reading of the sensor as an invalid value, and exemplarily setting the set invalid value as FF, so that the fault is injected into the sensor in a software mode, and meanwhile, the reading of the sensor is reported to the sensor monitoring module, and further management and alarm judgment of the reading of the sensor are realized through the sensor monitoring module.
