About virtualizing volumes
Virtualizing volumes is the process of mapping volumes in a source storage system to a target storage
system.
The volumes in the source storage system (registered and referred to as external volumes ) can
then be managed in the same way as the volumes in the target storage system (registered and referred
to as
internal volumes ).
Virtualizing volumes allows you to use P9000 Command View AE Suite to centrally manage volumes
in multiple source storage systems from a single storage system.
External volumes can be used for various purposes, including:
• External volumes can be allocated to hosts the same as internal volumes are.
• Important data on internal volumes can be backed up to external volumes.
• Infrequently accessed data on internal volumes can be moved to external volumes for archiving.
To externally connect an SMI-S Enabled storage system, execute it from CLI. For details about how to
use CLI to externally connect a storage system and disconnect an external connection, see the HP
P9000 Command View Advanced Edition Suite Software CLI Reference Guide.
Prerequisites for virtualizing volumes
Volume virtualization provides the capability to optimize storage services to applications by facilitating
movement of data between tiers and migration of data between different generations of technology.
Before virtualizing volumes, verify the following:
• The internal and external storage systems are registered in P9000 Command View AE Suite.
• External Storage Software is installed on the target storage system.
• The external storage system is connected to one or more external ports of the internal storage
system.
In addition, determine:
• The required number and capacity of volumes you are virtualizing.
• The number of paths between the external and internal storage systems.

Before you perform this task, review “ Prerequisites for virtualizing volumes ” on page 28.
To virtualize volumes:
1. From the Actions menu, select Virtualize Volumes.
2. Specify the appropriate information.
To change default values, click Path Priority Setting, Host Group and LUN Settings, or External
