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.
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.
