Hi Adai,

Thanks a lot.

I am facing the same issue with V3240 (ontap 8.0.2) in a customer site. Wondering what "resource limit id" shall I use to set up the "maxDedupeSizeInGB" parameter on v3240.


DFM command "dfpm reslimit" does not list any "maxDedupeSizeInGB" entry for V3240. The last Id that is used in the reslimit list is 214.

      Use the steps mentioned above by adai or in the burt public report to set the limit for V3240. Dedupe limit for V3240 with Ontap 8.0.2 is 16TB.
