Tape pool configuration

LUN policies versus tape pool policies
The Brocade encryption platform supports tape encryption configuration at the tape pool level and
at the LUN (tape drive) level. Tape drive (LUN) policies serve as a fallback mechanism in the event
that no tape pools are created or a given tape volume does not belong to any configured tape
pools. 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 pool labeling
Tape pools may be identified by either a name or a number depending on your backup application.
Numbers are always entered and displayed in hex notation. Names and numbers are independent;
it is possible to have one tape pool with the name "ABC" and another with the hex number "ABC".
The following rules apply when creating a tape pool label:
• Tape pool names are limited in length to 63 characters. They may contain alphanumeric
characters, and in some cases, underscores (_) and dashes (-).
• Tape pool numbers are limited to eight hex digits. Valid characters for tape pool numbers are
0-9, A-F, and a-f.
