We have got one datastore which is empty (No VMS on it) but still says under space utilization in vsphere client that half of 1.5TB is Virtual Disks and another half is free. I dont understand why its saying so instead of saying 100% of free space. ArcIT-495903.flv

The reason for this is that you made the datastore too large.

1.  Ensure that that the LUN/volume is deleted
2.  Create a datastore that is 2TB-512B  or less
3.  Format with 8MB block size

@paulsolov:- The datasize is already 8MB. And the datastore is already 1.46TB which < 2TB.

From what I see it is showing

total space: 2.9TB

Virtual disk: 1.49TB
Free Space: 1.49TB

If you created a LUN that is 2.9TB, I would advise to recreate.

It is showing 1.5TB free of 3TB.. not .50% of 1.5TB

That is correct.  Delete the entire LUN and recreate a LUN that is a just a bit under 2TB.  Depending on your needs you may want to keep the LUNs within 500GB to 1TB in size for better performance.

if you look at the Maximums Document

Max Size is 2TB-512bytes.
