You can use the volume move start command to enable encryption by moving an existing volume. You can use the same aggregate or a different aggregate.

About this task

Beginning with ONTAP 9.8, you can use volume move start to enable encryption on a SnapLock or FlexGroup volume.

If you enable “cc-mode” when you set up the Onboard Key Manager, volumes you create with the volume move start command are automatically encrypted. You need not specify -encrypt-destination true.

You can use aggregate-level encryption to assign keys to the containing aggregate for the volumes to be moved. A volume encrypted with a unique key is called an VE volume. A volume encrypted with an aggregate-level key is called an AE volume (for Aggregate Encryption). Plaintext volumes are not supported in AE aggregates.

What you’ll need

You must be a cluster administrator to perform this task, or an SVM administrator to whom the cluster administrator has delegated authority.

Delegating authority to run the volume move command

Steps

Move an existing volume and specify whether encryption is enabled on the volume:

To convert…	Use this command…
A plaintext volume to an VE volume	`volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination true`
An VE or plaintext volume to an AE volume (assuming aggregate-level encryption is enabled on the destination)	`volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-with-aggr-key true`
An AE volume to an VE volume	`volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-with-aggr-key false`
An AE volume to a plaintext volume	`volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination false -encrypt-with-aggr-key false`
An VE volume to a plaintext volume	`volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination false`

To convert…

Use this command…

A plaintext volume to an VE volume

volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination true

An VE or plaintext volume to an AE volume (assuming aggregate-level encryption is enabled on the destination)

volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-with-aggr-key true

An AE volume to an VE volume

volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-with-aggr-key false

An AE volume to a plaintext volume

volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination false -encrypt-with-aggr-key false

An VE volume to a plaintext volume

volume move start -vserver SVM_name -volume volume_name -destination-aggregate aggregate_name -encrypt-destination false

For the entire command syntax, see the man page for the command.

The following command converts a plaintext volume named vol1 to an VE volume:

cluster1::> volume move start -vserver vs1 -volume vol1 -destination-aggregate aggr2 -encrypt-destination true

Assuming aggregate-level encryption is enabled on the destination, the following command converts an VE or plaintext volume named vol1 to an AE volume:

cluster1::> volume move start -vserver vs1 -volume vol1 -destination-aggregate aggr2 -encrypt-with-aggr-key true

The following command converts an AE volume named vol2 to an VE volume:

cluster1::> volume move start -vserver vs1 -volume vol2 -destination-aggregate aggr2 -encrypt-with-aggr-key false

The following command converts an AE volume named vol2 to a plaintext volume:

cluster1::> volume move start -vserver vs1 -volume vol2 -destination-aggregate aggr2 -encrypt-destination false -encrypt-with-aggr-key false

The following command converts an VE volume named vol2 to a plaintext volume:

cluster1::> volume move start -vserver vs1 -volume vol2 -destination-aggregate aggr2 -encrypt-destination false

View the encryption type of cluster volumes:

volume show -fields encryption-type none|volume|aggregate

The encryption-type field is available in ONTAP 9.7 and later.

For complete command syntax, see the man page for the command.

The following command displays the encryption type of volumes in cluster2:
```
cluster2::> volume show -fields encryption-type

vserver  volume  encryption-type
-------  ------  ---------------
vs1      vol1    none
vs2      vol2    volume
vs3      vol3    aggregate
```

Verify that volumes are enabled for encryption:

volume show -is-encrypted true

For the entire command syntax, see the man page for the command.

The following command displays the encrypted volumes on cluster2:

cluster2::> volume show -is-encrypted true

Vserver  Volume  Aggregate  State  Type  Size  Available  Used
-------  ------  ---------  -----  ----  -----  --------- ----
vs1      vol1    aggr2     online    RW  200GB    160.0GB  20%

Result

If you are using a KMIP server to store the encryption keys for a node, ONTAP automatically pushes an encryption key to the server when you encrypt a volume.
