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: 0000:07:00.1 driver: 2.1.1.1 BFA[0000:07:00.0][info] BFA_AEN_PORT_ONLINE: Base port online: WWN = 10:00:00:05:33:26:b3:e2.
