Using cloud migration controls to override a volume's default tiering policy

You can change a volume's default tiering policy for controlling user data retrieval from the cloud tier to performance tier by using the -cloud-retrieval-policy option introduced in ONTAP 9.8.

  • Modifying a volume using the -cloud-retrieval-policy option requires ONTAP 9.8 or later.
  • You must have the advanced privilege level to perform this operation.
  • You should understand the behavior of tiering policies with -cloud-retrieval-policy.

    How tiering policies work with cloud migration

Modify the tiering policy behavior for an existing volume by using the volume modify command with the -cloud-retrieval-policy option: 
volume modify -volume <volume_name> -vserver <vserver_name> -cloud-retrieval-policy <policy_name>
vol modify -volume fp_volume4 -vserver vs0 -cloud-retrieval-policy promote
