Figure 5-117 Bus IDs that map to slot IDs
b. Run the ls -l /sys/class/block/ command to query the mapping between
NVMe PCIe SSD drive letters, PCIe bus IDs, and 80 IDs in /sys/class/
block/. See Figure
drive letters of NVMe PCIe SSDs according to the mapping between slot
IDs and bus IDs queried in
For example, drive letter nvme0n1 maps to PCIe bus ID 0000:03:00.0 and
80 ID 0000:00:03.1. According to
drive letter nvme0n1 maps to slot ID 31.
Run the following command to remove the NVMe PCIe SSD:
n > /sys/bus/pci/slots/ $slot /power
– echo
– In the command, the value of
removal, and the value 1 indicates hot insertion. If the value 0 is used,
the hot removal command is executed but the NVMe PCIe SSD is not
physically removed.
– For example, to hot-remove the NVMe PCIe SSD in slot 0, run the echo 0
> /sys/bus/pci/slots/30/power command.
