Removing and Replacing an NVMe Storage Drive
Using Oracle Linux
Note - NVMe storage drives are supported only on servers that are running the Oracle Solaris or
Oracle Linux operating system. Servers that are running Oracle VM, Windows Server, or Red
Hat Enterprise Linux do not support NVMe drives.
The following sections describe how to remove and replace an NVMe storage drive on a server
that is running the Oracle Linux operating system.

Unmount an NVMe Storage Drive
1.
Log in to Oracle Linux that is running on the server.
2.
Remove the NVMe storage device path.

To find the PCIe addresses (Bus Device Function), type:
# find /sys/devices |egrep ‘nvme[0-9][0-9]?$’
This commands returns output similar to the following:
/sys/devices/pci0000:80/0000:80:03.0/0000:b0:00.0/0000:b1:04.0/0000:b2:00.0/misc/nvme0
/sys/devices/pci0000:80/0000:80:03.0/0000:b0:00.0/0000:b1:05.0/0000:b4:00.0/misc/nvme1
In the above listing the PCIe addresses are highlighted in bold text.
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)
