What causes this error?

  • A The volume auto-grow is disabled.
  • B The LUN reached maximum capacity.
  • C The LUN can be expanded up to 10 times its original size.
  • D Space reservation is enabled.
Explanation

In ONTAP 9.4 and earlier, a LUN can be expanded to no more than 10 times its original size, subject to a 16 TB maximum. A 200 GB LUN therefore cannot be enlarged by 3 TB because the resulting size exceeds its allowed initial-geometry growth limit.
