Plug it in and enjoy. Works out of the box - never needed to configure anything.
If it's multipathed, you have to install and configure multipathd (https://help.ubuntu.com/lts/serverguide/multipath-setting-up-dm-multipath.html)

Hello, I'm having a big problem, I need to assign a lun FC directly to a virtual server. Just as it is possible in vmware and hyperv. I can work with luns on the proxmox server, allocating virtual machines on them. But how to proceed to assign a lun directly to the virtual machine?
This depends on your HBA support and NPIV to at least support this in Linux. I do not know of any method do achieve this in Proxmox VE. I tried in the past but failed. In general, this should be possible, because you can do it with QEMU:

@Fransuelo: what you want is called scsi pass through in the Proxmox / Qemu world.
I have not tested it myself but some users are using this with success:

He means that the VM has its own virtualized FC HBA on the fiber (at least you can do that on VMware and Hyper-V and I think he means that), such that the SAN switch is able to see it.
OK, right this is NPIV. As I understand it works similarly to SRV-IO, where you can splt a physical NIC in a number of personalities that you assign to the VMs via pci passthrough.
I don't have the hardware available to test but looking at the documentation @LnxBil mentionned it seems the hypervisor pass a fiber channel device ID (wwnn) to the guest.

@manu, Interesting working sr-iov. My FC is a brocade-825. Do you have any idea if it works with sr-iov or npiv? And how would I move to my virtual machine? Command line or would it be by proxmox interface?
This is all highly experimental. I tried to do this over a year ago and failed due to the "old" hardware for that (does also not work in VMware without proper SRV-IO stuff), so I really can't give you more information on that.
