FCoE issue in ucs with 5548up

Hello

I'm facing issue with FCoE ..

I'm using Fi-6248 UP nexus 5548UP

 

from 5k to Fi it is running with vpc and I have created two iseland SAN-A and SAN-B .

SAN-A is connected between 5548Up and FI-6248Up as well as SAN-B is connected between others two 548Up and FI-6248Up

 

I'm Using FCoE from both the sides to boot server from SAN..

I'm facing the issue like FCoE up link is not available ..from UCS

My Fi's are running with NPV mode .Initially before booting the server I can see the flogi of FI's in both the 5k's 5548 UP but when I try to boot the server those FI's flogi's are replaced with server vhba flogi.I should get both the flogi's Fi-A and Fi-B in both 5k 's but both sides Fi flogi's are replacing. with server vhba-0 and vhba-1...

from UCS it is showing FCoE uplink is not available...

FCoE Interface State is Intermediate and faults I'm getting F1082 and F1083..
