Re: expanding vmware lun without extents

Hi Friend,

VMware vSphere cannot modify the size of a LUN or other storage device on the array. Modifying the size of an array device must be done using the storage array vendor's management tools. (Refer-VMware KB: Growing or expanding a VMFS volume or datastore )

But you can increase the size of datastore.

Refer :below resources :
