Set up NVMe over Fibre Channel on the host side

NVMe initiator configuration in a Fibre Channel environment includes installing and configuring the nvme-cli package, and enabling the NVMe/FC initiator on the host.

1. Install the nvme-cli package:

   # zypper install nvme-cli

2. Enable and start the nvmefc-boot-connections service.

   systemctl enable nvmefc-boot-connections.service

   systemctl start nvmefc-boot-connections.service

3. Set Ipfc_enable_fc4_type to 3 to enable SLES12 SP4 as an NVMe/FC initiator.

   # cat /etc/modprobe.d/lpfc.conf
   options lpfc lpfc_enable_fc4_type=3

4. Re-build the initrd to get the Emulex change and the boot parameter change.

   # dracut --force

5. Reboot the host to reconfigure the Ipfc driver.

   # reboot

   The host is rebooted and the NVMe/FC initiator is enabled on the host.

   Note: After completing the host side setup, configuration of the NVMe over Fibre Channel ports occur automatically.
