Prepare an NVMe Storage Drive for Removal
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.
4. Prepare the NVMe drive for removal by powering off the NVMe drive slot. Type:
#
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.
