Figure 5 summarizes the relationships among the
physical device environment, TSM storage and policy objects, and
clients. The numbers in the following list correspond to the numbers in
the figure.
- (1)
- When clients are registered, they are associated with a policy
domain. Within the policy domain are the policy set, management class,
and copy groups.
- (2), (3)
- When a client backs up, archives, or migrates a file, it is bound to a
management class. A management class and the backup and archive copy
groups within it specify where files are stored and how they are managed when
they are backed up, archived, or migrated (space-managed files).
- (4), (5)
- Storage pools are the destinations for backed-up, archived, or
space-managed files. Copy groups specify storage pools for backed-up or
archived files. Management classes specify storage pools for
space-managed files.
Storage pools are mapped to device classes, which represent devices.
The storage pool contains volumes as indicated by the device type associated
with the device class. For example, a storage pool that is mapped to a
device class with a device type of CARTRIDGE contains only cartridge
tapes.
All devices require a device class that specifies at least a device
type.
- (6)
- Files that are initially stored on disk storage pools can migrate to tape
storage pools if the pools are set up in a storage hierarchy.
