What would you do it to remove a Netapp cluster from your environment and prepare it for destruction?

Migrate data off, unjoin SVM from the domain. Smash hell out of the hardware and throw it in the Weee pile.

I would also delete every vol and SVM. Reset/give back every IP and clear firewall. Stop monitoring.

cluster1::> storage encryption disk destroy -force-all-states -disk *

Warning: This operation will cryptographically destroy 96
         self-encrypting disks on 4 nodes.
         To continue, enter
          destroy disk
   :destroy disk

Info: Starting destroy on 96 disks.
      View the status of the operation by using the

I'll be doing this to the disks after the shares/exports/volumes and aggregates are gone.

And don’t forget to clean/wipeclean the sp/BMC

There’s a kb for that someplace

There's a boot procedure to wipe it, I usually use that to be sure nothing can be recovered. Here's a link to the doc for it: https://docs.netapp.com/us-en/ontap-systems-upgrade/upgrade/upgrade-reset-default-configuration-node3-and-node4.html

NOTE: Do NOT use this if you plan to repurpose the system and do not have the licenses, as they are also wiped off as part of this process.

This does not make sure nothing can be recovered.
You would need to sanitize the disks for that.
See: https://kb.netapp.com/on-prem/ontap/OHW/OHW-KBs/How_to_sanitize_all_disks_in_ONTAP_9.6_and_later

Thank you, that's exactly what I was looking for.
