Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.
Fig. 1 is a flowchart of a method for dynamically managing a server daughter card sensor according to an embodiment of the present invention, and as shown in fig. 1, the steps include:
step S101: the BMC detects whether the server daughter card on the server motherboard is in place.
Specifically, the BMC scans the state of the slot daughter card of the server motherboard and determines whether the server daughter card on the slot of the server motherboard is in place according to the state of the slot daughter card. For example, the BMC scans each slot of the server motherboard at regular time, obtains the slot daughter card status of each slot, if the in-place signal of the slot is 1, the daughter card is in place, and if the in-place signal of the slot is 0, the daughter card is not in place.

Specifically, the SDR is read from the nonvolatile memory of the server sub-card according to the corresponding relation between the BMC and the server sub-card. For example, in one SUB record in the BMC, the slot number field corresponds to the slot X, the FRU entity ID and the entity instance correspond to all sensors on the daughter card FRU, and when the daughter card a is inserted into the slot X, the BMC obtains the FRU entity ID and each SDR corresponding to the entity instance from the nonvolatile memory of the daughter card a inserted into the slot X.
Step S103: and the BMC stores the SDR read from the server daughter card, and specifically stores the SDR in an SDR library of the BMC so as to manage the server daughter card sensor by using the SDR.
The method further comprises the following steps: after the BMC stores the SDR read from the server sub-card, deleting the stored SDR of the server sub-card when the BMC detects that the server sub-card is pulled out of the server motherboard. Specifically, whether the SDR of the server sub-card is stored in an SDR library is judged according to the corresponding relation between the BMC and the server sub-card, and when the SDR of the server sub-card is judged to be stored in the SDR library, the SDR is deleted. For example: in a SUB record in the BMC, the slot number field corresponds to the slot X, the FRU entity ID and the entity instance correspond to all sensors on the daughter card FRU, when the daughter card A is pulled out of the slot X, the BMC inquires each SDR corresponding to the FRU entity ID and the entity instance of the daughter card A previously inserted into the slot X in an SDR library of the BMC, and deletes each SDR corresponding to the FRU entity ID and the entity instance of the daughter card A.
It will be understood by those skilled in the art that all or part of the steps in the method according to the above embodiments may be implemented by a program, which may be stored in a computer-readable storage medium, and includes steps S101 to S103 when the program is executed.
