Showing related volumes
You can show the FlashCopy mapping dependencies by selecting a target or source volume
in the FlashCopy window and clicking Show Related Volumes in the Actions drop-down
menu (as shown in Figure 10-39) or right-clicking the selected volume.
Figure 10-39 Show Related Volumes menu
The FlashCopy mapping dependency tree opens, as shown in Figure 10-40.

Restoring from a FlashCopy
Complete the following steps to manipulate FlashCopy target volumes to restore a source
volume to a previous known state:
1. Identify the FlashCopy relationship that you want to restore. In our example, we want to
restore FlashVol1, as shown in Figure 10-44.

2. Create a mapping by using the target volume of the mapping to be restored. In our
example, it is FlashVol1_01, as shown in Figure 10-45. Select Advanced FlashCopy
Use Existing Target Volumes.

3. The Source Volume is preselected with the target volume that was selected in the previous
step. Select the Target Volume from the drop-down menu (you select the source volume
that you want to restore). In our example, we select FlashVol1, as shown in Figure 10-46.
