Splitting a clone

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


  1. In the left navigation pane, click Resources, and then select the appropriate plug-in from the list.
  2. On 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.
  3. Select the appropriate resource from the list.
    The resource topology page is displayed.
  4. From the Manage Copies view, select the cloned resource (for example, the database or LUN), and then click .
  5. Review the estimated size of the clone that is to be split and the required space available on the aggregate, and then click Start.
  6. Monitor the operation progress by clicking Monitor > Jobs.
    The clone split operation stops responding if the SMCore service restarts and the databases on which the clone split operation was performed are listed as clones in the Resources page. You should run the Stop-SmJob cmdlet to stop the clone split operation, and then retry the clone split operation.

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.

For example:
<add key="CloneSplitStatusCheckPollTime" value="300000" />

The clone split start operation fails if backup, restore, or anther clone split is in progress. You should restart the clone split operation only after the running operations are complete.
