AX 150i LUN cannot initialize in windows 2012 R2 64 bit

I am using a Clariion AX150i in my office, i tried to connect windows 2012 R2 64 bit system to a LUN in this SAN, I installed the MPIO, ISCSI Initiater in the system. in the SAN i can see the active connection,  in the windows disk management i can see the drive, THE SCTUAL SIZE OF THE DISK, type ISCSI etc but cannot initialize the disk and cannot create the partition and could not store data. what should i do.

When i try to initialize with diskpart , i am getting an error message " DISKPART HAS REFERENCED AN OBJECT WHICH IS NOT UP-TO-DATE"

what are the configuration required to setup a cluster in this LUN.

please help Me.
