This commands returns output similar to the following:
/sys/bus/pci/slots/100/address:0000:12:00
/sys/bus/pci/slots/101/address:0000:13:00
/sys/bus/pci/slots/102/address:0000:14:00
/sys/bus/pci/slots/103/address:0000:15:00
For example, the PCIe address 0000:12:00.0 matches the PCIe slot number (100) for the
drive labeled NVMe0 on the system front panel.
3. Remove the NVMe storage device path.
a.
Use the umount command to unmount any file systems that are mounted on
the device.
In Linux, NVMe drives do not use the standard block device labeling, such as /dev/sd*.
For example, NVMe drive 0 that has a single namespace block device would be /dev/
nvme0n1. If you formatted and partitioned that namespace with a single partition, that
would be /dev/nvme0n1p1.
b. Remove the device from any multiple device (md) and Logical Volume
Manager (LVM) volume using it.
If the device is a member of an LVM Volume group, then it may be necessary to move data
off the device using the pvmove command, then use the vgreduce command to remove the
physical volume, and (optionally) pvremove to remove the LVM meta data from the disk.
c.
If the device uses multipathing, run multipath -l and note all the paths to the
device. Then, remove the multipathed device using the multipath -f device
command.
d.
Run the blockdev --flushbufs device command to flush any outstanding I/O
on all paths to the device.
Prepare the NVMe drive for removal by powering off the NVMe drive slot. Type:
4.
#
echo 0 > /sys/bus/pci/slots/slot_number/power
Where slot_number is the PCIe slot number (e.g., 100, which represents the drive labeled
NVMe0 on the system front panel).
5. Verify that the blue OK to Remove indicator on the NVMe drive is lit.
