Complete this task to discard changes to FlashCopy® target
volumes to form a consistency group on the target volumes as part of a disaster
recovery process.
You cannot discard changes to FlashCopy target volumes unless you
have modified the FlashCopy relationship using the FlashCopy
Revertible action and have selected the Allow target to be
restored to pre-FlashCopy state option, which changes the Restorable property
value to Yes.
If a FlashCopy consistency group formation operation
does not complete, you must determine whether to discard changes (revert to
a previous consistent state) or commit the operation to the current state.
As part of a disaster recovery process, determine the state of the consistency
groups in the affected sessions. The Discard Changes task specifies that the
previous consistency group that was created by the Global Mirror session
becomes the current state, and committing changes is no longer possible.
