Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

In view of the foregoing, a first aspect of the embodiments of the present invention provides an embodiment of a method for detecting a UBM backplane based on a BMC. Fig. 1 is a schematic diagram illustrating an embodiment of a method for detecting a UBM backplane based on BMC according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps performed in the BMC:

s1, receiving commands to be executed by the UBM backplane, and setting different sequence numbers for each command;

s2, matching the received execution result with the command according to the sequence number, and recording the result in a log;

s3, monitoring the UBM backboard; and

s4, responding to the UBM backboard, analyzing the log and positioning the position where the abnormality occurs.

UBM (Universal backplate management) is a new type of universal Backplane management scheme. UBM provides a generic backplane management framework through which Host can determine backplane functionality, DFC (device fabric connector) status and control information, and read DFC to HFC interconnection information on the backplane, etc.

On the UBM backplane, the HFC's Sideband I/O (Sideband input/output) signals need to be connected to the UBM controller and UBM FRU, with the high speed signals being connected directly from the HFC to the DFC. The UBM controller manages the Sideband I/O signals of HFC and DFC at the same time, uses I2C protocol to communicate with Host connected with HFC, and responds to the read-write command related to various UBM protocols sent by Host.

In the embodiment of the invention, a new I2C link is added between the Host and the BMC, the Host sends the corresponding Command to the BMC when sending the read-write Command to the UBM backboard, and simultaneously, the Host sends the received return state and the execution result to the BMC to record and store after the execution of the UBM Command is finished, so that when the backboard is in trouble, a user can conveniently log in a BMC interface to analyze the execution result of the corresponding Command and quickly locate the fault position.

The BMC receives commands to be executed by the UBM backplane, and each command corresponds to a different sequence number. In some embodiments, further comprising: the host sends a command to be executed by the UBM backplane to the UBM backplane controller and the BMC through I2C respectively. And the Host simultaneously sends the code of the UBM Command to be executed to a Controller and a BMC (baseboard management Controller) of the backboard through the I2C, and the Host simultaneously carries out sequence numbering on the Command when sending the code to the BMC so that the BMC carries out one-to-one matching on the Command and the execution result. In some embodiments, the each command corresponds to a different sequence number, including: each command is sequentially set with an increasing number according to the order of execution. Of course, this is not a limitation on the sequence number, which serves to distinguish commands, as long as any numbering is possible that achieves this effect.

In some embodiments, further comprising: and the host receives the execution result returned by the UBM backboard and sends the execution result to the BMC. After receiving the execution result returned by the UBM backplane, the Host sends the sequence number of the Command, the Command Command word and the execution result to the BMC, the BMC performs matching recording on the Command and the execution result to the log according to the received sequence number, and the specific Command code and the return result are processed in a differentiated manner according to the different Command. The specific communication formats of BMC and Host may be as follows:

in some embodiments, said analyzing said log and locating a location of an anomaly in response to said UBM backplane occurrence comprises: the execution results are analyzed in response to the execution results not having been received for more than a threshold time and/or an error between the execution results and the expected execution results exceeding a threshold. For example, the time threshold may be set to 1 second, and if the corresponding execution result is not received within 1 second after the BMC receives the command to be executed by the UBM backplane, it is determined that the UBM backplane is abnormal. Or, the expected execution result may be preset according to the command, for example, the expected execution result is 8-10, and the execution result obtained from the host is 7, and it is considered that the UBM backplane is abnormal. After the UBM backboard is abnormal, the position of the fault can be determined according to a specific execution result, and the fault can be solved quickly.

Fig. 2 is a flowchart illustrating an embodiment of a method for detecting a UBM backplane based on BMC according to the present invention. As shown in fig. 2, beginning at block 101 and proceeding to block 102, commands to be executed by the UBM backplane are received, each command corresponding to a different sequence number; proceeding to block 103, matching the execution result with the command according to the sequence number, and recording the result in the log; then proceed to block 104, monitor the UBM backplane; then, the process proceeds to block 105, whether the UBM backplane is abnormal is judged, if yes, the process proceeds to block 106, the log is analyzed, the abnormal position is located, and then the process proceeds to block 107 to end, and if not, the process ends directly.
