Welcome to the VMware Community forums. ESX(i) have a 2 TB LUN limit. With ESX it'll used up the first 2 TB and ignore the rest, but with ESXi for some reason it ignores 2 TB chunks and uses the rest (0.05 TB in your case). If you recreate the array as 2.0 TB - 512 B you'll be able to use that full amount of storage.
Full marks worked like a charm. Divied it up into 2 parts and they both showed up immediatly.
