System information

Note
These commands will only work if the d cbd settings for the Ethernet interface were not
changed.
5. Load the FCoE device now using:
# ifconfig ethX up
6. Start FCoE using:
# service fcoe start
The FCoE device should appear shortly, assuming all other settings on the fabric are correct.
To view configured FCoE devices, run:
# fcoeadm -i
After correctly configuring the Ethernet interface to use FCoE, Red Hat recommends that you set FCoE
and l l d pad to run at startup. To do so, use chkco nfi g, as in:
# chkconfig lldpad on
# chkconfig fcoe on
Warning
Do not run software-based DCB or LLDP on CNAs that implement DCB.
Some Combined Network Adapters (CNAs) implement the Data Center Bridging (DCB) protocol
in firmware. The DCB protocol assumes that there is just one originator of DCB on a particular
network link. This means that any higher-level software implementation of DCB, or Link Layer
Discovery Protocol (LLDP), must be disabled on CNAs that implement D CB.
25.7.1. Fibre-Channel over Et hernet (FCoE) T arget Set up
In addition to mounting LUNs over FCoE, as described in Section 25.7, “ Configuring a Fibre-Channel
Over Ethernet Interface” , exporting LUNs to other machines over FCoE is also supported.
Important
Before proceeding, refer to Section 25.7, “Configuring a Fibre-Channel Over Ethernet
Interface” and verify that basic FCoE set up is completed, and that fco ead m -i displays
configured FCoE interfaces.
