Windows
Windows FC-NVMe does not support point to point (also called N2N) direct attach
to Target/LUN configuration. It does support fabric configuration through FC
Switch fabric.
Unloading and Reloading the Linux Driver
Follow the instructions in this section to unload and reload the Linux driver.
To unload and reload the Linux driver:
1. List all the FC-NVMe connected target controllers by issuing the following
command:
# ls /dev/nvme* | grep -E nvme[0-9]+$
The preceding command should list all connected /dev/nvme[x]
devices. For example:
/dev/nvme0
/dev/nvme1
2. Disconnect all of the FC-NVMe target devices by issuing the following
commands to each of the /dev/nvme[x] devices listed in Step 1:
# nvme disconnect -d /dev/nvme0
# nvme disconnect -d /dev/nvme1
3. Unload the current driver by issuing the following command:
# modprobe -r qla2xxx
4. Reload the driver to auto-discover the FC-NVMe subsystems by issuing the
following command:
# modprobe -v qla2xxx
