Chapter 6. Volume configuration
A volume is a logical disk provisioned out of a storage pool and is recognized by a host with a
unique identifier (UID) field and a parameter list.

the classes of volumes available, and the topologies that they are associated with. It also
provides an overview of advanced customization available.
The second part describes how to create volumes by using the GUI’s
Quick and Advanced
volume creation menus, and shows you how to map these volumes to defined hosts.
The third part provides an introduction to the new volume manipulation commands, which are
designed to facilitate the creation and administration of volumes used for
IBM HyperSwap
