You can use SnapCenter to split a cloned resource from the parent resource. The clone that is split becomes independent of the parent resource.
About this task
- You cannot perform the clone split operation on an intermediate clone.
For example, after you create clone1 from a database backup, you can create a backup of clone1, and then clone this backup (clone2). After you create clone2, clone1 is an intermediate clone, and you cannot perform the clone split operation on clone1. However, you can perform the clone split operation on clone2.
After splitting clone2, you can perform the clone split operation on clone1 because clone1 is no longer the intermediate clone.
- When you split a clone, the backup copies and clone jobs of the clone are deleted.
- For information about clone split operation limitations, see the Logical Storage Management Guide.
Steps
- In the left navigation pane, click Resources, and then select the appropriate plug-in from the list.
- In the Resources page, select the appropriate option from the View list:
Option Description For database applications Select Database from the View list. For file systems Select Path from the View list. - Select the cloned resource (for example, the database or LUN), and then click
. - Review the estimated size of the clone that is to be split and the required space available on the aggregate, and then click Start.
- Monitor the operation progress by clicking .
After you finish
If you want a longer poll time or shorter poll time to check whether the clone is split or not, you can change the value of CloneSplitStatusCheckPollTime parameter in SMCoreServiceHost.exe.config file to set the time interval for SMCore to poll for the status of the clone split operation. The value is in milliseconds and the default value is 5 minutes.
