QuestionQ36

ONTAP SAN implementation testing and troubleshooting

A LUN shows 90% space used in the NetApp ONTAP CLI, whereas a Windows Server reports only 10% space used.

What should be the first action to address this issue?

  • A Enable space allocation.
  • B Enable automatic resizing.
  • C Disable space allocation.
  • D Disable automatic resizing.
Explanation

ONTAP space allocation enables SCSI thin-provisioning support for a LUN. Windows supports this feature, allowing it to communicate released blocks through SCSI UNMAP so ONTAP can reclaim the unused LUN space. Automatic resizing does not resolve a discrepancy caused by unreclaimed blocks.
