1. Add package fcoe-util.x86_64, this package is included in the RHEL6 GA DVD.
2. Configure FCoE ( I used eth4).
#cd /etc/fcoe/
#cp cfg-ethx cfg-eth4
3. Start lldpad
#service lldpad start
4. Configure DCB
#dcbtool sc eth4 dcb on
#dcbtool sc eth4 app:fcoe e:1
5. Start FCoE
#service fcoe start
6. Assign an IP address to eth4 (optional for FCoE)
7. Check FCoE status
fcoeadm -i
8. Setup lldpad and fcoe to start when booting
# chkconfig lldpad on
# chkconfig fcoe on
