Use this page to confirm the volume pairs in which Metro Mirror will start a background copy and copy out-of-synchronous tracks.
This process copies data, that was updated on the source volume of the volume pair, to the associated target volume, since the specific copy pair was last suspended. Click OK to resume processing of the volume pair associated with the out-of-synchronization tracks. The volume pairs that you resumed will move back to Full duplex mode when out-of-synchronization tracks equal zero and the copy is complete.
