FlexClone volumes and LUNs
You can clone FlexVol volumes that contain LUNs and LUN clones.
Note: LUNs in this context refer to the LUNs that Data ONTAP serves to clients, not to the array LUNs used for storage on a storage array.
When you create a FlexClone volume, LUNs in the parent volume are present in the FlexClone volume but they are not mapped and they are offline. To bring the LUNs in the FlexClone volume online, you need to map them to igroups. When the LUNs in the parent volume are backed by Snapshot copies, the FlexClone volume also inherits the Snapshot copies.
If the parent volume contains FlexClone files or FlexClone LUNs (LUNs created by using the volume file clone create command), those FlexClone files and FlexClone LUNs are present in the FlexClone volume and they share storage with the FlexClone files and FlexClone LUNs in the parent volume.
