IBM Tivoli Storage Manager, Version 7.1

Tivoli Storage Manager storage objects

Devices and media are represented by objects that you define. Information about these objects is stored in the Tivoli® Storage Manager database.

You can query, update, and delete the following objects:

Library
Drive
Device class
Disk Devices
Storage pool
Storage pool volume
Data mover
Path
Server

Libraries
A physical library is a collection of one or more drives that share similar media-mounting requirements. That is, the drive can be mounted by an operator or by an automated mounting mechanism.
Drives
A drive object represents a drive mechanism within a library that uses removable media. For devices with multiple drives, including automated libraries, you must define each drive separately and associate it with a library.
Device class
Each device that is defined to Tivoli Storage Manager is associated with one device class. The device class specifies the device type and media management information, such as recording format, estimated capacity, and labeling prefixes.
Library, drive, and device-class objects
Library objects, drive objects, and device-class objects taken together represent physical storage entities.
Storage pools and storage-pool volumes
A storage pool is a collection of volumes that are associated with one device class and one media type. For example, a storage pool that is associated with a device class for 8-mm tape volumes contains only 8 mm tape volumes.
Data movers
Data movers are devices that accept requests from Tivoli Storage Manager to transfer data on behalf of the server. Data movers transfer data between storage devices without using significant server, client, or network resources.
Paths
Paths allow access to drives, disks, and libraries. A path definition specifies a source and a destination. The source accesses the destination, but data can flow in either direction between the source and destination.
Server objects
Server objects are defined to use a library that is on a SAN and that is managed by another Tivoli Storage Manager server, to use LAN-free data movement, or to store data in virtual volumes on a remote server.
