s101: sending broadcast messages to each RAID card according to the terminal id of each RAID card, wherein the terminal id of each RAID card corresponds to a PCIe bus address;
specifically, before this step is performed, an operation of enumerating a PCIe (Peripheral Component Interconnect Express) device by the server BIOS is further included, and it is understood that the RAID card is a PCIe device, and the purpose of the operation of enumerating the PCIe device is to determine all RAID cards in the system. And then allocating independent PCIe bus addresses for the RAID card and the BMC (Baseboard Management Controller), and allocating terminal ids corresponding to the PCIe bus addresses for the RAID card and the BMC by the server system Management engine, so that the RAID card can be managed directly according to the terminal ids in the following process, and the Management efficiency is improved. After the terminal ids of the RAID cards and the BMC are allocated, the BMC acquires the terminal id of each RAID card, and each RAID card may also acquire the terminal id of the BMC. After the operation is executed, the BMC sends the broadcast message to each RAID card through each terminal id, all RAID cards can be informed at one time in a mode of sending the broadcast message, data do not need to be sent to each RAID card independently, the flow load of the server is low, and correspondingly, each RAID card can also send a feedback message to the BMC according to the terminal id of the BMC.

The RAID card firmware records the serial port log files according to the recording period, after receiving the broadcast message sent by the BMC, the RAID card interacts with the BMC through an MCTP over PCIe protocol and sends the corresponding serial port log files, and therefore the serial port log files can be stored to the BMC without being connected with a physical serial port connector on the RAID card.
The recording period can be set to be relatively short so as to achieve the purpose of recording serial port log files in real time, the comprehensiveness and integrity of log records are achieved, and later-stage analysis is facilitated.

The problem can be reflected by the serial port log file which is closer to the current moment, so that when analysis is needed, the target serial port log file acquired in the n nearest sending periods to the current moment can be selected for analysis, and the efficiency is improved.
In conclusion, by adopting the scheme of the application, the serial port log file of the RAID card can be stored without connecting a serial port line. When a system downtime problem caused by an RAID card occurs in the research, development and test process and the operation of a data center server, the serial port log file can be analyzed at the first time, the root cause is searched to achieve rapid debug and solve the problem, a large amount of time for reproducing the problem and capturing the serial port log file is saved, the problem solution in the product research and development process is accelerated, if the problem occurs at a client, the problem can be timely solved, and the customer satisfaction degree is increased.
