Nexus 7000 and FCoE port settings

Hi Gurus,

I have posted on storage networking forum already about the issue but none has replied. So thought of posting in this forum.

1st thing i want to know is the difference between shared and permanent intreface membership in a VDC. Actually how they play if the interface is shared between two VDC? Specially when one is storage VDC and one is networking.

I just have created a storage VDC and shared some interface members with the default VDC. But unable to turn on priority flow control for the interfaces in the storage VDC. Error shown is given below. Just looking for an explanation. If  any white paper or some documents available for deploying FCoE using Nexus 7000 will be helpful. How do we do ETS bandwidth management in Nexus 7000 for FCoE?

fcoe-dvt(config-if)# priority-flow-control mode auto

ERROR: pfc config not allowed on shared interface (0x1a000000)
