Slot IDs
Step 3
Query the bus IDs based on the slots IDs.
Run the following command to query the bus ID of a NVMe PCIe SSD:
cat /sys/bus/pci/slots/$slot/address
In the command,
$slot
indicates the slot ID, which is obtained in
.

Bus IDs that map to slot IDs
, the bus ID of the NVMe PCIe SSD in slot 8 is
0000:81:00
.
Step 4
Query information about the NVMe PCIe SSD drive letters.
For example, to query information about the NVMe PCIe SSDs in
/sys/class/block/
, run the
following command:
ls -l /sys/class/block/
