In Figure 8-18 the mirrored volume, Mir, is limited in its actual capacity by its
smallest child, Sim2. To resize Sim2 to two terabytes, simple volume, Sim3, is
concatenated to Sim2 to create the resized cube volume, XSim 2.

Retracting a Volume
After resizing a volume but before expanding its hierarchy, you can use the CLI
command volume retract to delete the added volume(s) used to resize the
original volume. The head of the volume hierarchy is retracted, not the resized
volume.
