b. To obtain the slot number (APIC ID) for the bus address, type the following
command to list all of the PCIe slot numbers and the corresponding bus
addresses:
#
egrep –H '.*' /sys/bus/pci/slots/*/address
This commands returns output similar to the following:
/sys/bus/pci/slots/10/address:0000:b8:00
/sys/bus/pci/slots/11/address:0000:b6:00
/sys/bus/pci/slots/12/address:0000:b2:00 (instance nvme0, pcie slot 12, drive label
nvme2)
/sys/bus/pci/slots/13/address:0000:b4:00 (instance nvme1, pcie slot 13, drive label
nvme3)
In the above output, the bus addresses for the corresponding NVMe instances are
highlighted in bold text.
In the above output, notice that the instance names for the NVMe drives does not
Note -
correspond to the NVMe drive labels on the front of the server, that is, pci/slots/12/address:
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
storage drive label on the front of the server, see
NVMe Storage Drives" on page
c. Disconnect all users of the NVMe drive and back up the NVMe drive data as
needed.
i.
Use the umount command to unmount any file systems that are mounted
on the device.
ii. 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.
iii.
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.
iv.
Run the blockdev --flushbufs device command to flush any outstanding
I/O to all paths to the device.
