Subject: Fibre channel network interfaces + Linux SAN

Two things I'm trying to solve with my fc hardware.  How do I enable these 
for IP networking, and how do I offer say lvm logical volumes behind Linux 
as a SAN? I'd like nodes to be bootable and offer specific volumes as their 
disks.  I'm using 2.6.28 

As for networking, I vaguely remember setting up IPv4 on fibre channel some 
time ago.  So far I have two hosts connected to a Compaq Storage Works FC 
arbitrated loop.  Each host has Online for 
/sys/class/fc_host/hostN/port_state.  I can't find the network device in 
/proc/net/dev or via ifconfig -a. 

riddle: 2.6.18-5-xen-vserver-686
00:0a.0 Fibre Channel [0c04]: Emulex Corporation LP8000 Fibre Channel Host 
Adapter [10df:f800] (rev 02) 

armada: 2.6.18-5-vserver-686
01:0b.0 Fibre Channel [0c04]: Emulex Corporation LP8000 Fibre Channel Host 
Adapter [10df:f800] (rev 02) 

Both have lpfc loaded (if you didn't guess that by now).  I thought there 
was a more generic ip<->fc net driver. I did find net/802/fc.c using fc%d as 
the net device, and lpfc.ko is the only module I've found containing fc%d. 

modinfo lpfc seems to apply to the fc layer only.  I did find some outdated 
Emulex documentation about configuring this hardware for a network 
interface. 

Any comments? 

Thanks, 

Scott
