Method, apparatus, device and system for capturing trace of NVME hard disc

A method for capturing a trace of a Non-Volatile Memory Express (NVME) hard disc, wherein the method is applied to a fixture plate including a processor and a dial switch, the method comprising:

• acquiring register error information, wherein the register error information is register information collected by a Basic Input Output System (BIOS) when an error occurs in a peripheral component interconnect express (PCIe) link in which the NVME hard disc is located;
• parsing address information carried by the register error information to obtain a corresponding error type;
• determining whether the error type is consistent with a current error type corresponding to the dial switch;
• triggering a protocol analysis instrument to capture the PCIe trace of the NVME hard disc if the error type is consistent with the current error type corresponding to the dial switch;
• wherein the fixture plate is connected with the protocol analysis instrument, and the BIOS sends the register error information to the fixture plate through a Baseboard Management Controller (BMC), and the address information of the register error information has a corresponding relationship with the error type.

A device for capturing a trace of an NVME hard disc comprising a processor, wherein the processor is used to perform the following steps when the processor executes computer programs stored in a memory:

• acquiring register error information, wherein the register error information is register information collected by a Basic Input Output System (BIOS) when an error occurs in a PCIe link in which the NVME hard disc is located;
• parsing address information carried by the register error information to obtain an error type;
• determining whether the error type is consistent with a current error type corresponding to a dial switch of a fixture plate;
• triggering a protocol analysis instrument to capture a PCIe trace of the NVME hard disc if the error type is consistent with the current error type corresponding to the dial switch in the fixture plate.
