15.1 Overview
The InForm OS space management commands allow you to change the way that virtual
volumes are mapped to logical disks in order to move virtual volume regions from one logical
disk to another. This enables you to compact logical disks, and free up disk space so that it can
be reclaimed for use by the system. These commands require the use of the InForm CLI.
15.2 Reclaiming Space
As discussed in Chapter 2, Overview, virtual volumes are made up of multiple logical disks,
where each logical disk contains regions that are mapped to the virtual volume.
