Recently, I revert the AFF8020 from cDOT 9.1 to cDOT 8.3.2P5, but there is some strange condition afterward.
The System Manager and Command line can't enable inline dedupe
The error as below:
DATA ONTAP APF failed: Inline Deduplication requires an effective cluster version of DATA ONTAP 8.3.2 or later
Please help to share your experience to see how it solves.
