0. activate fcoe first = config t > feature fcoe
1. create vfc
interface vfc 20
bind interface ethernet 20

then
create vsan database
e.g.
config t
vsan database
vsan 20 interface vfc20

then
normal MDS stuffs like creating alias, adding HBA pWWN to alias
then creating zone for FC
active zoneset,

after that in SAN - HP or V-max or clarion just add in storage group.
you shud be able to see the LUNs.

thats all.

It will be supported in Q1/2011 but you need 4458 mininum. Cisco SE are
trailing it in their lab.

Also, if you've a massive data center to design, its not good to use 55xx.
I'd rathe ruse MDS and let 55xx do ethernet switching only.
