we may have some movement, but how can you resize a lun downwards ???

it might be that ESX doesn't support LUNS over 2Tb

we orginally had one that was 1 but we extended it to 2.5Tb, within the lun the VMFS is only 1Tb so, how do i resize the partition down ???

this might not be the way forwards but we need that data so any help would be great
