Tape pool configuration
Tape pools are used by tape backup application programs to group all configured tape volumes
into a single backup to facilitate their management within a centralized backup plan. A tape pool is
identified by either a name or a number, depending on the backup application. Tape pools have
the following properties:
• They are configured and managed per encryption group at the group leader level.
• All encryption engines in the encryption group share the same tape pool policy definitions.
• Tape pool definitions are not needed to read a tape. The tape contains enough information
(encryption method and key ID) to enable any encryption engine to read the tape. Tape pool
definitions are only used when writing tapes.
• Tape pool names and numbers must be unique within the encryption group.
• If a given tape volume belongs to a tape pool, tape pool-level policies (defaults or configured
values) are applied and override any LUN-level policies.
• Tape drive (LUN) policies are used if no tape pools are created or if a given tape volume does
not belong to any configured tape pools.
