You can use the snap delete command to view ownership information of busy Snapshot copies. Before you can delete a busy Snapshot copy, you need to release the Snapshot copy from the application that is using it.
This information is useful for determining why a particular Snapshot copy is busy, and whether to stop the activity in progress. For example, if the snap delete command output displays a locked Snapshot copy that is imposing a resource constraint, you can delete that Snapshot copy and free up space.
