I need to write the procedures for tape verification and wish some
guidance:
(Background info:  AIX 4.3.3 running TSM 4.2.1 on LTO libraries).

1. How do you verify your permanent offsite tapes are still valid (Audit
Volume or other)?
2. How often do you verify those tapes?
3. How long will most LTO tapes take to do an Audit Volume?
4. What other tools are available verify a TSM tape is valid?
5. What is the best tool to use to verify that a "backupset" is still
valid?

Thanks for your responses.
