You can delete clones if you find them no longer necessary.

You cannot delete clones that acts like source for other clones.

For example, if the production database is db1, database clone1 is cloned from backup of db1 and subsequently clone1 is protected. The database clone2 is cloned from backup of clone1. If you decide to delete clone1, you must first delete clone2, and then delete clone1.

  2. In the Resources page, either select the resource or resource group from the View drop-down list.

  3. Select the resource or resource group from the list.

    The resource or the resource group topology page is displayed.

  4. From the Manage Copies view, select Clones either from the primary or secondary (mirrored or replicated) storage systems.

  5. Select the clone, and then click delete icon.

After you finish

Sometimes the file systems are not deleted. You must increase the value of the CLONE_DELETE_DELAY parameter by running the following command:./sccli Set-SmConfigSettings

After modifying the value of the parameter, restart the SnapCenter Plug-in Loader (SPL) service.
