Recovering from a disaster through the fast reverse process
The Global Mirror fast reverse restore feature allows a FlashCopy relationship to be reversed without waiting for the background copy of the original FlashCopy to complete.
About this task
You can use the fast reverse restore feature of FlashCopy to speed up the recovery process.
- Create a FlashCopy target on the existing Metro Mirror source by choosing the FlashCopy target and a Metro Mirror source.
- Select the Fast Reverse restore
option. FlashCopy copies the partial data that copied to Volume C before the disaster occurred to Volume B. The action 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.
