Figure 11-23 Selecting source and target for a FlashCopy mapping Figure 11-22 Creating a FlashCopy mapping with an existing target The Create FlashCopy Mapping window opens as shown in Figure 11-23. In this window,  you create the mapping between the selected source volume and the target volume you  want to create a mapping with. Then, click  Add . Important:  The source volume and the target volume must be of equal size. Therefore,  only targets of the same size are shown in the list for a source volume. Volumes that are a target in a FlashCopy mapping cannot be a target in a new  mapping. Therefore, only volumes that are not targets can be selected. To remove a mapping that was created, click  , as shown in Figure 11-24 on page 473. 472  Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
