This issue is not related to remaining/free space. It has something to do with drive's tracks/cylinders/heads/etc.

You can resize LUNs with <6G only up to 64G. LUNs with >6G up to 10x of its original size. Google for "netapp lun resize 10x".

Proper implementation should based on these rules either clone & resize or do a completely new LUN (create & copy?).
