32 Understanding Veritas Volume Manager
How VxVM handles storage management
Note: You can use the Veritas Intelligent Storage Provisioning (ISP) feature to
create and administer application volumes. These volumes are very similar to
the traditional VxVM volumes that are described in this chapter. However, there
are significant differences between the functionality of the two types of volume
that prevent them from being used interchangeably. Refer to the Veritas Storage
Foundation Intelligent Storage Provisioning Administrator’s Guide for more
information about creating and administering ISP application volumes.
In Figure 1-10, volume vol01 has the following characteristics:
■ It contains one plex named vol01-01.
■ The plex contains one subdisk named disk01-01.
■ The subdisk disk01-01 is allocated from VM disk disk01.
