Recovering from a disaster using the fast reverse process

Use this process for the Global Mirror fast reverse restore feature, which allows a FlashCopy relationship to be reversed without waiting for the background copy of the original FlashCopy to complete.

You can use the fast reverse restore feature of FlashCopy to speed up the recovery process. Using the DS Storage Manager, you make the following selections:

  1. Create a FlashCopy target on the existing Metro Mirror source by choosing the FlashCopy target and a source Metro Mirror .
  2. Select the Fast Reverse restore option.
    FlashCopy copies the partial data that had been copied to Volume C before the disaster occurred to Volume B. This creates a consistent copy on Volume B. Processing also provides a background copy of the consistent group for Volume B.
    Note: When you initiate the fast reverse restore process, Volume C becomes unusable.
