Preparing a FlashCopy consistency group–Restore

Use the Preparing a FlashCopy® Consistency Group–Restore in the SAN Volume Controller Console to prepare all the FlashCopy mappings within a consistency group.

This panel indicates that the target virtual disks (VDisks) of the mappings in this group are the source VDisks of some other active FlashCopy mappings. When the FlashCopy consistency group is being prepared with restore option, the prepare operation can fail if dependencies exist between the any of the FlashCopy mapping in the consistency group and other FlashCopy mappings on the cluster that have also been prepared or started with the restore option.

To determine if dependencies exist between the selected FlashCopy mappings and other mappings, use the Viewing FlashCopy Mappings panel to determine whether other FlashCopy mappings are linked to the selected mapping through shared source or target VDisks. If the restore option is set on any of these linked mappings, then you cannot prepare the selected FlashCopy mapping with the restore option.

Complete the following steps to start a 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 Prepare a Consistency Group from the task list and click Go. If the selected FlashCopy consistency group contains has mappings where target VDisks are also source VDisks in other active FlashCopy mappings, then the Prepare FlashCopy Consistency Groups–Restore panel displays.
  4. Click Prepare for Restoring.
