Complete this task to commit data to FlashCopy® target volumes to form a
consistency group on the target volumes as part of a disaster recovery process.
You can commit changes to FlashCopy target volumes if 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, the consistency groups at the remote site might be only
partially formed. You must verify the consistency group on the remote site
and determine whether the changes need to be “rolled forward” (committed)
or “rolled backward” (discarded). The commit task specifies that the last
consistency group that has been created by the Global Mirror session
is committed to the current state, and that reverting to the
previous consistency group state is no longer possible.

following steps to commit data to FlashCopy target volumes:
- In the navigation, select . A list of FlashCopy volumes
