Volume Migration Using the Tiered Storage Manager CLI
1-1 Tiered Storage Manager Software Components
The following software components are needed to use the Tiered Storage Manager CLI to perform volume
migration.
• Device Manager server
The Device Manager server is a prerequisite program for the Tiered Storage Manager server.
Tiered Storage Manager obtains configuration information about storage subsystems as well as
information about volumes (LDEVs) from the Device Manager server. Also, the user management
functionality provided by Device Manager is used to perform system registration for the user groups and
users that use Tiered Storage Manager.
• Tiered Storage Manager server (Management server)
The Tiered Storage Manager server (Management server) performs migration (relocation of volume data)
within the domain control storage subsystem and the external storage subsystems that are connected to
it, based on information received from the Management client.
To use the Tiered Storage Manager server, the Device Manager server must be installed on the same
server.
• Tiered Storage Manager client (Management client)
The Tiered Storage Manager client (Management client) is used by system administrators, and storage
administrators on the host side.
The Management client provides users with information needed to perform migration, as obtained from
Tiered Storage Manager server, and relays migration requests from the user to the Management server.
The Management client consists of a CLI client and a Web client. The CLI client requires a Java
execution environment.
For details on how to operate the Web client, please refer to the HP StorageWorks XP Tiered Storage
Manager User's Guide.
