In Figure 88 (page 189), 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.

Table 63 How it works—shared snapshots

C#First, a volume

C#_snap1C#_snap2C#_SCsnapNext, 3 snapshots

C#class_xFinally, SmartClone volumes from the latest snapshot

Latest snapshot becomes clone point

Older two snapshots become shared between clone point

and SmartClone volume.

The shared snapshots also appear under all the volumes which share them. In Figure 88 (page 189),

they are displayed under the original volume from which they were created, and under the single

SmartClone volume that shares them. The selected shared snapshot is highlighted in the navigation

window, under both the volumes with which it is shared. Shared snapshots can be deleted.

Creating SmartClone volumes

You create SmartClone volumes from existing volumes or snapshots. When you create a SmartClone

volume from another volume, you first take a snapshot of the original volume. When you create a

SmartClone volume from a snapshot, you do not take another snapshot.

To create a SmartClone volume

When you create SmartClone volumes, you either set the characteristics for the entire group or set

them individually.
