You can add volumes to FabricPool by creating new volumes directly in the FabricPool-enabled aggregate or by moving existing volumes from another aggregate to the FabricPool-enabled aggregate.
Creating a volume for FabricPool
When you create a volume for FabricPool, you have the option to specify a tiering policy. If no tiering policy is specified, the created volume uses the default snapshot-only tiering policy. For a volume with the snapshot-only or auto tiering policy, you can also specify the tiering minimum cooling period.
Moving a volume to FabricPool
When you move a volume to FabricPool, you have the option to specify or change the tiering policy for the volume with the move. Starting in ONTAP 9.8, when you move a non-FabricPool volume with inactive data reporting enabled, FabricPool uses a heat map to read tierable blocks, and moves cold data to the capacity tier on the FabricPool destination.
