0000:b2:00 corresponds to instance nvme0; however, on the front of the server, this drive is
labeled NVMe2. For a table that shows the relationship between the pci/slot# and the NVMe

Use the umount command to unmount any file systems that are mounted
on the device.
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 might 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 metadata from the disk.
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.
Run the blockdev --flushbufs device command to flush any outstanding
I/O to all paths to the device.
