AFF8020 revert from cDOT9.1 to cDOT 8.3.2P5 in-dedupe can't be turn on


Hi All,


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.


Many thanks.


Tony Wu



Did you follow the revert-procedure and disable all the new 9.0 and 9.1 functionality, e.g. compaction and so on?

Maybe somewhere there's still fragments of the newer configs left and it confuses ONTAP...





Please check the output for version (for cluster version) and version -node * (for node versions) commands.

Ensure that the OS version matches across all nodes and the cluster.
