Figure 90 Navigation window with shared snapshots
.
In Figure 90 on page 245, the original volume is C#. Three snapshots were created from C#:
• C#_snap1
• C#_snap2
• C#_SCsnap
Then a SmartClone volume was created from the latest snapshot, C#_SCsnap. That volume has a
base name of C#_class. The older two snapshots, C#_snap1 and C#_snap2, become shared snapshots,
because the SmartClone volume depends on the shared data in both those snapshots.

Older two snapshots become shared between clone point and SmartClone
volume.
The shared snapshots also appearunder all the volumes which share them. In
they are displayed under the original volume from which they were created, and under the single
