NVMe/FC Configuration on Linux Hosts
For details on NVMe/FC configuration for Red Hat Enterprise Linux hosts, see
Red Hat Knowledge Article 4706181 (Is NVMe
over Fibre (NVMeoF) supported...)

Setting the Linux Host NVMe Qualified Name
About this task
You can configure the host NVMe Qualified Name (NQN) using either Hostname or UUID. For visibility and simplicity, it is
recommended to use Hostname.
Steps
1.
Connect to the ESXi host as
root
.
2.
Edit the
/etc/nvme/hostnqn
file and modify the UUID format to Hostname format.
Before:
# nvme show-hostnqn
nqn.2014-08.org.nvmexpress:uuid:daa45a0b-d371-45f6-b071-213787ff0917
After:
# nvme show-hostnqn
nqn.2014-08.org.nvmexpress:Linux-Host1
3.
The value must comply with
NVMe Express Base Specification
, Chapter 4.5 (NVMe Qualified Names).
4.
If you want to revert back to UUID format, run the following command to create a new NQN and update the
/etc/nvme/
hostnqn
file:
# nvme gen-hostnqn
nqn.2014-08.org.nvmexpress:uuid:51dc3c11-35b6-e311-bcdd-001e67a3bceb

2.
Edit the
/etc/modprobe.d/qla2xxx.conf
configuration file with the following data:
options qla2xxx ql2xextended_error_logging=1 ql2xfwloadbin=2 ql2xnvmeenable=1
NOTE:
ql2xnvmeenable=1
enables NVMe-oF, and
ql2xnvmeenable=0
disables it.
