When trying to resize a LUN, you may receive the following error:
Data ONTAP API Failed: New size exceeds this LUN's initial geometry.
This occurs when you try to increase a LUN size to more than 10x it's original size, e.g. increasing a 50GB lun to 1TB. The 10x limitation is a hard limit and, to the best of my knowledge, cannot be exceeded. You'll need to trash the LUN and recreate it to exceed the 10x limitation.
