Step 3 Run the cat /sys/bus/pci/slots/
the drive corresponding to the slot ID and record all bus IDs. As shown in
9-12, the bus ID of slot 8 is 0000:81:00.
In the command,

Step 4 Run the ls -l /sys/class/block/ command to list the mapping between NVMe PCIe
SSD drive letters, PCIe bus IDs, and 80 IDs in /sys/class/block/, as shown in
9-13.

Step 5 Obtain the mapping between slot IDs and SSD drive letters based on the mapping
between the slot IDs and bus IDs. For example, in
corresponding to nvme0n1 is 0000:81:00.0, and the 80 ID is 0000:80:02.0.
