Starting a FlashCopy consistency group–Prepare and start

You can use the Starting FlashCopy® Consistency Group panel in the SAN Volume Controller Console to prepare and start the FlashCopy consistency group. Before FlashCopy mappings in the selected FlashCopy consistency can start, all the mappings must first be prepared. When the FlashCopy mappings are prepared, any data that resides in the cache for the source virtual disks (VDisks) is transferred to disks thus ensuring that the copy operation includes all data currently on the source VDisks. After the preparation action completes for the FlashCopy mappings in the consistency group, the system starts the FlashCopy consistency group.

1. Click Manage Copy Services > FlashCopy Consistency Groups in the portfolio. The Viewing FlashCopy Consistency Groups panel is displayed.
2. Select the appropriate group's row from the table.
3. Select Start a Consistency Group from the task list and click Go. If the selected FlashCopy consistency group contains mappings that are not in the prepared state then the Starting FlashCopy Consistency Groups–Prepare and Start panel displays.
4. Click Prepare and Start.
