Splitting a FlexClone volume from its parent volume
If you want the FlexClone volume to have its own disk space, rather than using that of its parent, you can split it from its parent. After the split, the FlexClone volume becomes a normal flexible volume.
Before you begin
The FlexClone volume must be online.
About this task
The clone-splitting operation deletes all the existing Snapshot copies of the clone. The Snapshot copies that are required for SnapMirror updates are also deleted. Therefore, any further SnapMirror updates might fail.
You can pause the clone-splitting operation, if you have to perform any other operation on the volume. You can resume the process after the operation is complete.
Steps
1. From the home page, double-click the appropriate storage system.
2. In the navigation pane, click Storage > Volumes.
3. Select the FlexClone volume that you want to split from its parent volume.
4. Click Clone > Split.
