Need help adding FC luns

[Matty Sarro]

Thanks for your help everyone. I am pursuing this both on the SAN
itself, as well as from the OS. The SAN itself apparently defaults to
using loop mode FC, and it showed both ports as in a disconnected
state. I switched it to auto-negotiate and the ports report as up on
the SAN. After rebooting the server I see the following in dmesg:

scsi1 : Brocade FC/FCOE Adapter, model: Brocade-425 hwpath:

Nothing shows up in fdisk -l.
