Applies to

  • ONTAP 9
  • NetApp Volume Encryption (NVE)
  • NetApp Aggregate Encryption (NAE)

Answer

Use one of the following methods:

1. Use another aggregate:

a. Move the volumes to another non-NAE aggregate and convert them to plain text volumes:

::> volume move start -vserver <vserver_name> -volume <volume_name> -destination-aggregate <aggr_name> -encrypt-destination false -encrypt-with-aggr-key false

2. Use the same aggregate:

a. Assuming you have space in the existing NAE aggregate, move the volumes to convert them from NAE to NVE (which NAE aggregates do allow) in the same aggregate:

::> volume move start -vserver <vserver_name> -volume <volume_name> -destination-aggregate <aggr_name> -encrypt-destination true -encrypt-with-aggr-key false

b. After all the volumes are NVE, and no NAE encrypted volumes exist, disable NAE on the aggregate:::> aggregate modify -aggregate <aggr_name> -node <node_name> -encrypt-with-aggr-key false. 

Note: Make sure that no aggregate snapshot copies exist, or the command will fail.

c. Move the NVE volumes to unencrypt them and convert them to plain text:

::> volume move start -vserver <vserver_name> -volume <volume_name> -destination-aggregate <aggr_name> -encrypt-destination false

Note: If the step b was missed, the volume move will fail with the error:

Error: command failed: The destination aggregate "aggr_name" is an NAE (NetApp Aggregate Encryption) aggregate. Non-encrypted volumes are not supported in such aggregates.
