We have a new FAS 2552 with 8.3.1 and it seems to insist on using ADP.
Tried setting the following;
setenv root-uses-shared-disks false
setenv allow-ssd-partitions false
setenv root-uses-shared-ssds false
Then removing the partitions from all disks and removing ownership in maint mode...
But after a reboot and option 4, ADP is back on and every other disk is "shared"
Anyone done this before?

NetApp strongly discourages customers moving away from the ADP feature of clustered Data ONTAP 8.3.x.Please call the technical support for further assistance and log a case.

We have a number of customers who wanted to layout their new cDOT infrastructure without using the ADP function, primarily to reduce their data aggregate count, and maintain consistency with other existing deployments. Typically these solutions comprise multiple shelves, so there are partitioned and non-partitioned disks to start with.
Start the build process as normal to establish the cluster, create a new small aggregate from the non-partitioned disks on each controller, move the root aggregates, remove and re-assign partition ownership so that any given disk and all of its partitions are owned by a single node, then unpartition the disks and zero the spares.
To move the root aggregate, refer to the following: https://kb.netapp.com/support/index?page=content&id=3013873&locale=en_US
To invoke the environment variable change use: setenv root-uses-shared-disks? false the first time you drop to Loader during the root aggregate move process.
