Use this procedure in place of the fast reverse process. The fast
reverse process allows a FlashCopy relationship to be reversed without waiting
for the background copy of the original FlashCopy to complete.
It is not necessary to use the fast reverse feature of FlashCopy
for your recovery. However, the wait for recovery is significantly longer
if you do not.
- Initiate a background copy on the Volume B to Volume C FlashCopy
relationship.
- Wait for the background copy to complete. Observe the out-of-sync
tracks.
- Select the Reverse relationship and Initiate background
copy options on the Volume B to Volume C FlashCopy relationship. This
reverses the FlashCopy relationship such that Volume C is the source and Volume
B is the target.
