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.
NOTE
Tape pool configurations must be committed to take effect. There is an upper limit of 25 on the
number of tape pools you can add or modify in a single commit operation. Attempts to commit a
configuration that exceeds this maximum fails with a warning. Note that there is also a five second
delay before the commit operation takes effect.
