● Stop all programs accessing the NVMe PCIe SSD.
● If a
le system is mounted to the NVMe PCIe SSD, unmount the le system
from it.
● Query the mapping between slot IDs and drive letters of NVMe PCIe SSDs
using the following method:
a. Open the command terminal on the OS, run the cat /sys/bus/pci/slots/
$slot
/address command to query the bus IDs that map to slot IDs, and
record all bus IDs. For example, slot 31 maps to bus ID 0000:03:00, as
shown in Figure 5-117.
In the command,
$slot
indicates a hard disk slot on the OS. Its value
ranges from 30 to 37.
