2. Click the Storage tab.
3. In the Storage tab navigation pane, select the volume.
4. In the right pane, click the Mappings tab.
5. In the right pane, select the server for which you want to modify mapping settings, then click Edit Settings. The Edit Settings wizard appears.
6. Click Continue. The wizard advances to the next page.
7. Clear the Allow the Storage Center to automatically determine the best Controller to activate Volume on check box.
8. From the Activate Volume on Controller drop-down menu, select the controller that should process IO for the volume/server mapping.
9. When you are finished, click OK.
