7 Creating Volumes
Introduction
This chapter describes how to create volumes in Volume Manager
(VxVM). Volumes are logical devices that appear as physical disk
partition devices to data management systems. Volumes enhance
recovery from hardware failure, data availability, performance, and
storage configuration.
Volumes are created to take advantage of the VxVM concept of virtual
disks. A file system can be placed on the volume to organize the disk
space with files and directories. In addition, you can configure
applications such as databases to organize data on volumes.
NOTE Disks and disk groups must be initialized and defined to VxVM before
volumes can be created from them. See Chapter 2, “Administering
Disks,” on page 63 and Chapter 4, “Creating and Administering Disk
Groups,” on page 151 for more information.
