Hello Viswa, The 1.5TB lun will need to be deleted and recreated to a smaller capacity. The VMWare lun can be extended to the recovered space assuming both the VMWare lun and newly free up disks are configured with the same Raid protection.  Caution: Prior to the delete, the data residing on the NAS lun will need to be backup or migrated to a different location.  Regards,  EMC
Hi  We have installed VNXe-3100 Unified storage to one of our customers.  1. The storage size for a vmware LUN was allocated as 800GB 2. There are 3 LUNS allocated for 3nos NAS servers with 1.5TB, 800GB & 1TB respectively. 3. The vmware capacity is now running low on disk space. 4. Out of the 1.5TB NAS volume, only 400GB is being used.  Now my question is -- Q. Can we be able to reduce the capacity in the NAS LUN & reassign that space to the vmware LUN.  Appreciate your help at the earliest.  Thanks - Viswa
