vfc error disabled because of Ethernet port down?

[sokarlsson]

We are building a new datacenter and is starting to set up the SAN.

This small DC consist of 2 Nexus 5596UP, a Compellent SAN and 2 Dell M1000e cassis with blade servers.

naive FC part in Nexus has been easy to set up but we have problems with the FCOE setup.
Since the blades are not installed yet none of the Ethernet ports are up. As soon as we bind an ethernet port to a vfc the vfc goes to error disable with this message:

%PORT-2-IF_DOWN_ERROR_DISABLED: %$VSAN 1900%$ Interface vfc101 is down (Error disabled)

Config snippets:

vlan 1900

  fcoe vsan 1900

  name VSAN-A-FCOE

vlan 1901

  name VSAN-B-FCOE

vsan database

  vsan 1900 name "VSAN-A"

  vsan 1901 name "VSAN-B"

interface vfc101

  bind interface Ethernet1/1

  no shutdown

vsan database

  vsan 1900 interface vfc101

  vsan 1900 interface fc2/13

  vsan 1900 interface fc2/14

  vsan 1900 interface fc2/15

  vsan 1900 interface fc2/16

interface Ethernet1/1

  switchport mode trunk

  spanning-tree port type edge trunk

vlan 1900
  fcoe vsan 1900
  name VSAN-A-FCOE

vlan 1901
  name VSAN-B-FCOE

vsan database
  vsan 1900 name "VSAN-A"
  vsan 1901 name "VSAN-B"

vsan database
  vsan 1900 interface vfc101
  vsan 1900 interface fc2/13
  vsan 1900 interface fc2/14
  vsan 1900 interface fc2/15
  vsan 1900 interface fc2/16

interface vfc101
  bind interface Ethernet1/1
  no shutdown

interface Ethernet1/1
  switchport mode trunk
  spanning-tree port type edge trunk

Do the vfc go error disable because the ethernet interface being down? I was under the impression it should just go "down"

Forgot. Software release on the Nexus switches are 5.0(3)N2(1)

What you are seeing is normal.. Here are outputs from my lab switch where I shut Eth1/20 which is tied to vFC 20

Thanks a lot. Being used to IOS and that error disable means that one manually have to bring an error disabled port up so I got a bit worried.
