The Operation Failed with Error 32788

Hello,

I have installed windows server 2012 R2 Stnd Edition & running VM (Windows Server 2012 R2) on Hyper-V.

machine is working fine but i want to attached "Fiber channel Adapter" because i want to attach my EMC SAN AX5 LUNs with VM.

When i add hardware with VM then i am getting error message when switch ON VM  "The Operation Failed with Error 32788 "

I tried a lot but could not get any possitive result. Kindly let me know how to get EMX SAN LUN on Virtual Machine as my VM already working and i want to attach SAN LUNs to VM. 

Regards,
