I could not find nvme-fc at all.

Could you please confirm whether UBUNTU support FC-NVME with Cisco UCS Blade / x-series servers.

If yes then please share the fnic driver version.

"Note: In the depends list nvme-fc and nvmet-fc are not found."

This seems to be a misinterpretation.
For some historic reason in the kernel module naming the dash and underscore characters are somewhat interchangeable.

All the mentioned modules nvme-core.ko, nvme-fc.ko and nvme-fabrics.ko are available in the current kernel packages in the /lib/modules/<kernelversion>/kernel/drivers/nvme/host/nvme-core.ko directory.

What kind of "support for FC-NVMe with fnic driver 1.6.0.53" are you missing?

I am not aware that Ubuntu does something specific. If that support is available in the standard Linux kernel, then Ubuntu will have that function in its kernel packages. If the Linux kernel does not have it, Ubuntu will not have it either.

Thanks for information.

As said in this mail chain "Ubuntu server does not support FC-NVME with Cisco"

So, just want to know if there is any plan for Ubuntu to support FC-NVME with Cisco UCS Servers.
