No disks were found on which to perform cluster validation tests

Hi 

I decide to Run File Server Failover clustering on My lab.

I install Two Windows Server 2012 in VM (Hyper-V machine) and then install file server and fail over clustering.

My problem is when i use validation , it cant find any disk despite i have create another Disk for fail over as you can see in the following pivtures

and in the fail over cluster i cant find any disk , and in the validation report i see this warning .

I Love God,because he help me to find Technet.
