Description
This KB explains how to disable all storage efficiency (SE) features on a volume.
Beginning ONTAP release 9.2, storage efficiency is enabled by default on All Flash FAS (AFF) platforms.
Under certain conditions such as below, it becomes necessary to undo the SE savings:
- Converting a thin provisioned volume to thick and host a LUN, since AFF by default creates thin provisioned volumes
- Changing the SE compression type
- Changing the application io size to improve the compression savings
