How Veritas Volume Manager works
Databases require their storage media to be robust and resilient to failure. It is
vital to protect against hardware and disk failures and to maximize performance
using all the available hardware resources. Using a volume manager provides this
necessary resilience and eases the task of management. A volume manager can
help you manage hundreds of disk devices and makes spanning, striping, and
mirroring easy.
Veritas Volume Manager (VxVM) builds virtual devices called volumes on top of
physical disks. Volumes are accessed by a file system, a database, or other
applications in the same way physical disk partitions would be accessed. Using
volumes, VxVM provides the following administrative benefits for databases:

Allows volume layout changes without application or
database downtime. Online relayout can be used to
change performance or reliability characteristics of
underlying storage.
Online relayout
Ensures that all mirrors contain exactly the same data
and that the data and parity in RAID-5 volumes agree.
