Tape pools overview

Tape cartridges and volumes can be organized into a tape pool (a collection of tape media). The

same data encryption keys are used for all cartridges and volumes in the pool. Tape pools are used

by backup application programs to group all tape volumes used in a single backup or in a backup

plan. The tape pool name or number used must be the same name or number used by the host

backup application. If the same tape pool name or number is configured for an encryption group,

tapes in that tape pool are encrypted according to the tape pool settings instead of the tape LUN

settings.

Encryption switches and encryption blades support tape encryption at the tape pool level (for most

backup applications) and at the LUN (tape drive) level. Since Tape Pool policies override the LUN

(tape drive) policies, the LUN pool policies are used only if no tape pools exist or if the tape

media/volume does not belong to any configured tape pools.
