3. Verifying BMC failure resolution function
The part adopts a complex scene to annotate errors and verifies the fault analysis function of the BMC.
Specifically, by using the characteristic of remote, each remote terminal is opened, multiple error types are triggered at the same time, and the BMC fault analysis function is verified. The specific verification steps comprise:
step S1: and simultaneously injecting the same IERR error into the device of the same preset testing machine by adopting each remote terminal, and checking whether the BMC can analyze the corresponding fault analysis information.
The preset device of the tester in step S1 may be any one of a CPU, a memory, and a PCIE of the tester, for example, the preset device is set as a CPU of the tester in this embodiment. In specific implementation, a person skilled in the art may replace the CPU of the tester with the memory of the tester or the PCIE.
Specifically, in this embodiment, when this step S1 is implemented, it is checked whether the BMC of the test machine can resolve the fault resolution information corresponding to the first IERR error for the CPU of the test machine by using the remote terminal a, the remote terminal B, and the remote terminal C to simultaneously inject the same IERR error (hereinafter, referred to as "first IERR error") to the CPU of the test machine. If the check result is that the BMC can resolve the corresponding fault resolution information, the test of step S1 passes, otherwise, the entire test fails.
Step S2: and simultaneously injecting different IERR errors into the devices of the same preset testing machine by adopting each remote terminal, and checking whether the BMC can analyze corresponding fault analysis information.
Specifically, the remote terminal a, the remote terminal B and the remote terminal C are adopted to simultaneously inject different IERR errors into preset devices of a tester of the tester, and check whether the BMC can analyze corresponding fault analysis information. If the check result is that the BMC can resolve the corresponding fault resolution information, the test of step S2 passes, otherwise, the entire test fails.
For example, in step S2, the IERR errors injected by the remote terminal a, the remote terminal B, and the remote terminal C to each relevant device of the tester are an IERR error 1, an IERR error 2, and an IERR error 3 in sequence, and the IERR error 1, the IERR error 2, and the IERR error 3 are different (i.e., all different).
In addition, similar to step S1, the device of the tester preset in step S2 may be any one of a CPU, a memory, and a PCIE of the tester, and is set as the memory of the tester in this embodiment. In specific implementation, a person skilled in the art may replace the memory of the tester at that location with the CPU or PCIE of the tester.
And step S3: and simultaneously injecting IERR errors into the devices of at least two preset testers by adopting each remote terminal, and checking whether the BMC can analyze correct fault analysis information.
For example, in this embodiment, the at least two preset devices of the tester are the CPU and the PCIE of the tester, and when the specific implementation is implemented, the CPU and the PCIE of the tester may be integrally replaced by the CPU, the memory, and the PCIE of the tester, or may be replaced by a combination of any other related devices of the tester.
In the implementation, the remote terminal a, the remote terminal B and the remote terminal C are adopted to simultaneously inject the IERR error into the CPU and the PCIE of the test machine, wherein the IERR error is respectively injected into the CPU and the PCIE of the test machine by the remote terminal a, the IERR error is respectively injected into the CPU and the PCIE of the test machine by the remote terminal B, and the IERR error is respectively injected into the CPU and the PCIE of the test machine by the remote terminal C, and after the injection of the IERR error is completed, whether the BMC of the test machine can analyze correct fault analysis information is checked, if the IERR error can be analyzed, the test in the step S3 is passed, otherwise, the whole test fails.
It should be noted that, in this embodiment, the IERR errors injected into the CPU of the tester and the PCIE of the tester by using the remote terminal a are different, the IERR errors injected into the CPU of the tester and the PCIE of the tester by using the remote terminal B are different, and the IERR errors injected into the CPU of the tester and the PCIE of the tester by using the remote terminal C are different.
And step S4: and simultaneously injecting IERR errors and non-IERR errors into the devices of the same preset testing machine by adopting each remote terminal, checking whether the BMC can correctly distinguish the injected IERR errors and non-IERR errors, and performing correct fault analysis.
The preset device of the tester in step S4 may be any one of a CPU, a memory, and a PCIE of the tester, and in the specific implementation, the preset device may be selectively set by a person skilled in the art, for example, the preset device is a PCIE of the tester in this embodiment (the PCIE may be modified by the person skilled in the art according to an actual situation, for example, the preset device may be modified into the CPU or the memory of the tester).
When the step S4 is specifically implemented, the remote terminal a, the remote terminal B, and the remote terminal C are used to simultaneously inject an IERR error and a non-IERR error into the PCIE of the test machine (where the steps include that the remote terminal a is used to inject an IERR error and a non-IERR error into the PCIE of the test machine, the remote terminal B is used to inject an IERR error and a non-IERR error into the PCIE of the test machine, and the remote terminal C is used to inject an IERR error and a non-IERR error into the PCIE of the test machine), check whether the BMC can correctly distinguish the IERR error and the non-IERR error injected by the test machine, and check whether the BMC can perform correct failure analysis. If the check result is that the BMC can correctly distinguish the injected IERR error from the non-IERR error and make a correct fault analysis, the entire test is successful (i.e., the BMC fault diagnosis test of the test machine passes), otherwise the entire test fails (i.e., the BMC fault diagnosis test of the test machine fails).
Further, to facilitate the management of each remote terminal, the method 100 further includes a remote terminal management step: for managing each remote terminal. During specific implementation, a single management terminal can be used for performing addition, deletion, modification and query management on each remote terminal before the functions of configuring the remote terminal environment, checking the test environment and verifying the fault analysis of the BMC are performed.
