Use this page to confirm the FlashCopy® volume pair on which updates to the target volume of the volume pair will be discarded and restored to a previous FlashCopy relationship. The FlashCopy relationship is not deleted until changes are discarded.
During Global Mirror operations, if a FlashCopy target volume has inconsistent data, you can discard data and restore the FlashCopy pair back to a previous FlashCopy relationship. In most of the cases, the volumes are consistent and this process is not necessary.
When you select Discard changes from the action drop down and select a source volume that has more than one target volume, all related FlashCopy relationships will be listed on this page. Of the volumes that you select, at least one or more must be restorable.
