Preparing a FlashCopy mapping–Restore

You can use the Preparing FlashCopy® Mapping–Restore panel in the SAN Volume Controller Console to prepare the FlashCopy mapping for a restore operation.

During the prepare operation for a FlashCopy mapping, the cluster verifies that the target virtual disk (VDisk) is also not a source VDisk in another active FlashCopy mapping. If no dependencies for the selected mapping exist, then the mapping is prepared and can be started. If a dependency exists, you can prepare the mapping to restore data only. The restore option allows you to recover from application failures without changing existing backup configurations or without losing target data.  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 prepare a FlashCopy mapping:

  1. Click Manage Copy Services > FlashCopy Mappings in the portfolio. The Viewing FlashCopy Mappings panel is displayed.
  2. Select the FlashCopy mapping that you want to start and select Prepare a Mapping from the task list, and click Go. If the selected FlashCopy mapping has target VDisk that are also source VDisk in another active FlashCopy mapping, then the Prepare FlashCopy Mapping–Restore panel displays.
  3. Click Prepare for Restoring. The Viewing FlashCopy Mappings panel is displayed.
