Answer

  • The size to which you can increase your LUN varies depending upon your version of ONTAP.
 

ONTAP version

Maximum LUN size

ONTAP 9.12.1P2 and later

128 TB for AFF, FAS, and ASA platforms

ONTAP 9.8 and later

  • 128 TB for All-Flash SAN Array (ASA) platforms

  • 16 TB for non-ASA platforms

ONTAP 9.5, 9.6, 9.7

16TB

ONTAP 9.4 or earlier
  • 10 times the original LUN size, but not greater than 16TB, which is the maximum LUN size.
  • For example, if you create a 100 GB LUN, you can only grow it to 1,000 GB.
  • The actual maximum size of the LUN might not be exactly 16TB. ONTAP rounds down the limit to be slightly less.
