It can be understood that the RAID card is a PCIe device, and enumerating PCIe The purpose of the operation of the device is to identify all RAID cards in the system. Then assign independent PCIe bus addresses to the RAID card and BMC (Baseboard Management Controller), and the server system management engine assigns the RAID card and BMC with terminal ids corresponding to their respective PCIe bus addresses, so that the id manages RAID cards to improve management efficiency. After the terminal ids of each RAID card and the BMC are allocated, the BMC obtains the terminal id of each RAID card, and each RAID card can also obtain the terminal id of the BMC. After performing the above operations, the BMC sends broadcast messages to each RAID card through each terminal id. By sending a broadcast message, it can notify all RAID cards at one time without sending data to each RAID card separately. The traffic load is low. Correspondingly, each RAID card can also send feedback packets to the BMC according to the terminal id of the BMC.

The firmware of the RAID card records the serial log files according to the recording period. After receiving the broadcast message sent by the BMC, the RAID card interacts with the BMC through the MCTP over PCIe protocol and sends the corresponding serial port log files, so as to realize that there is no need to connect the physical device on the RAID card. The serial port connector can save the serial port log file to the BMC.

Among them, the recording period can be set to be relatively small, in order to achieve the purpose of recording serial port log files in real time, and the comprehensiveness and integrity of log records are convenient for later analysis of problems.

S103: Record the feedback message corresponding to each RAID card.
