Physically connect additional FCoe cables between the IOMs and fabric interconnects.
Enable the additional ports in the Cisco Unified Computing System Manager. Configure the appropriate ports as a server port. Do this for both fabric interconnects.
Check the Cisco UCS chassis connectivity policy. By default, the chassis connectivity policy is set to global. This means that connectivity control is configured when the chassis is newly discovered, using the settings configured in the chassis discovery policy. Once the chassis is discovered, the chassis connectivity policy controls whether the connectivity control is set to none or port channel.
As acknowledging the chassis will be interruptive, acknowledge (as of Cisco UCS Manager Release 2.2(4)) or reset both IO modules individually.
