The number of hard disks expanded by the data center server is increased, and the number of corresponding hard disk backplanes is increased. From the perspective of asset Management, a Baseboard Management Controller (BMC) is required to be able to perform real-time asset Management on a hard disk backplane of a server.
In a server system, the BMC is generally used to manage assets of the server, such as hard disk backplane information and hard disk information. The BMC obtains the hard disk backplane and the hard disk information channel in the server, and currently, determines the hard disk backplane and the hard disk information channel by using Inter-Integrated Circuit (I2C) information. The specific method comprises the following steps: different hard disk backplanes adopt different addresses, and in the fourth channel of I2C, the BMC lists all hard disk backplane addresses in the broadcast range. When the BMC captures the information of the hard disk back plates, a broadcast call address mode is adopted, all the hard disk back plates mounted on the fourth channel can be matched with addresses sent by broadcast, and then response is carried out. The BMC judges that the broadcast address receives the response and returns a data signal, judges that the hard disk backboard exists and further judges that the hard disk on the hard disk backboard is in place, and in an actual situation, judges that a certain hard disk backboard exists by mistake and further judges that the hard disk is in place due to the existence of signal interference.

Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
In the actual product application process, the BMC acquires the hard disk backplane and the hard disk information channel in the server and judges by using I2C information at present. For example, the BMC is designed to support 3 different backplanes with addresses of 0X20, 0X22, and 0X24, but only 0X20 is installed in the configuration of actual product sales, and when the BMC broadcasts three addresses of 0X20, 0X22, and 0X24 at the same time, Data bits after two addresses of 0X22 and 0X24 are both recognized as Data due to signal interference, so the BMC error determination system has 3 hard disk backplanes.
Based on the problems, the invention provides a method for detecting the in-place of a server hard disk, which can increase the stability of reading the information of a hard disk backboard by a BMC. Under the condition that the current BMC judges whether the design of the hard disk exists by using the address of the hard disk backboard of I2C and the data response information, the BMC sets the actual shipment quantity of the configured hard disk backboard in the FRU by using the information of the BMC FRU according to different configuration types, so that the misjudgment phenomenon of the backboard by the BMC caused by the interference problem is avoided. Meanwhile, different FRU information is refreshed according to the number of the expanded backplates in subsequent expansion, and the update of the number of the display backplates of the BMC can be realized.
Fig. 1 is a schematic block diagram illustrating a method according to an embodiment of the present application, and as shown in fig. 1, a BMC includes a field replaceable unit FRU, where the FRU includes information about a hard disk backplane in the server, including:
And step 120, the BMC determines that N hard disks exist in the server according to the received address and response data of each hard disk backplane in the M hard disk backplanes and the hard disk backplane information in the server, wherein N and M are positive integers.
In a system planning stage, the number of hard disk backplanes supported is planned, or the number of the existing hard disk backplanes is planned, so that the number information of the hard disk backplanes, the identification of the hard disk backplanes or the information of other hard disk backplanes can be written into a Field Replaceable Unit (FRU).
In step 120, in another way, after the BMC receives the response data corresponding to one hard disk backplane, it cannot determine that the hard disk backplane exists, and only when the response data is received according to the hard disk backplane information included in the FRU, it can determine that the hard disk backplane exists, and thus determine that the hard disk on the hard disk backplane is in place.
Therefore, the method provided by the embodiment of the application can judge whether the hard disk backboard exists or not by writing the information of the hard disk backboard in the FRU in advance and saving the corresponding response data of the hard disk backboard, and further determine whether the hard disk exists on the hard disk backboard. The method provided by the application can effectively avoid the situation that the BMC misjudges the hard disk backboard caused by the interference problem.
Optionally, as an embodiment of the present application, when the hard disk backplane information includes identification information of each hard disk backplane in the server, the BMC determines that N hard disks exist in the server according to the received address and response data of each hard disk backplane in the M hard disk backplanes and the identification information of each hard disk backplane in the server.
That is to say, when the FRU prestores which hard disk backplanes exist on the server at all, when the BMC receives the addresses of the M hard disk backplanes and the corresponding response data, it will determine which of the M hard disk backplanes actually exist, and further determine the hard disks on the existing hard disk backplanes.
Optionally, as an embodiment of the present application, when the hard disk backplane information includes number information of each hard disk backplane in the server, the BMC determines that N hard disks exist in the server according to the received address and response data of each hard disk backplane in the M hard disk backplanes and the number information of the hard disk backplanes in the server.
That is, when the FRU prestores the maximum number of the hard disk backplates existing on the server, when the BMC receives the addresses of the M hard disk backplates and the corresponding response data, it will determine which of the M hard disk backplates actually exist according to the maximum number of the hard disk backplates, and further determine the hard disk on the existing hard disk backplates.
Optionally, as an embodiment of the present application, the method further includes: and updating the hard disk backboard information in the server included in the FRU.
Fig. 2 shows a schematic flow chart of a method of another embodiment of the present application. As shown in fig. 2, the BMC sends a broadcast message to the hard disk backplane on the server, and the hard disk backplane that receives the broadcast message returns response data, otherwise, it is determined that the hard disk backplane does not exist, and the hard disk on the hard disk backplane does not exist; and when the returned response data of the hard disk backboard is received and the existence of the hard disk backboard is determined according to the hard disk backboard information, determining that the hard disk on the hard disk backboard also exists or not.
For example, the BMC is designed to support 3 different backplanes, the addresses of the backplanes are 0X20, 0X22, and 0X24, and only 0X20 is installed in the configuration for actual product sales, for example, the number of hard disk backplanes stored in the FRU is 1, when the BMC broadcasts three addresses of 0X20, 0X22, and 0X24 at the same time, Data bits after two addresses of 0X22 and 0X24 are both identified by error as having Data due to the interference problem of signals, and since the number of hard disk backplanes in the FRU is 1, the BMC determines that the system has 1 hard disk backplane 0X20 and the hard disk on the hard disk backplane exists.
Fig. 3 shows a schematic block diagram of an apparatus according to another embodiment of the present application, and as shown in fig. 3, the apparatus 300 includes:
a field replaceable unit 310, the field replaceable unit 310 being configured to store hard disk backplane information in the server.

And the processing unit 330 is configured to determine that N hard disks exist in the server according to the received address and response data of each hard disk backplane in the M hard disk backplanes and the hard disk backplane information in the server, where N and M are positive integers.
Optionally, as an embodiment of the present application, when the hard disk backplane information includes identification information of each hard disk backplane in the server, the processing unit 330 is configured to determine that N hard disks exist in the server according to the received address and response data of each hard disk backplane in the M hard disk backplanes and the identification information of each hard disk backplane in the server.
