cvlabel reports wrong size

I have 4 MAC PRO (late 2013) running Sierra OS. Disk Utility and cvlabel reports different sizes for disks.

I am unable to configure second Xsan volume . /dev/disk2 is 120TB as reported by diskutil but cvlabel reports 15 TB. Any help would be greatly appreciated.

bash-3.2# diskutil list
