Chapter 10. Copy services 515
In its basic mode, the IBM FlashCopy function copies the contents of a source volume to a
target volume. Any data that existed on the target volume is lost, and that data is replaced
by the copied data.
From the Copy Services option on the main panel, use the Consistency Groups option, as
shown in Figure 10-11. A
Consistency Group is a container for mappings. You can add
many mappings to a Consistency Group.

From the Copy Services option on the main panel, use the FlashCopy Mappings pane, as
shown in Figure 10-12. A
FlashCopy mapping defines the relationship between a source
volume and a target volume.
