As Wanda Prather said:

*       If I have a problem reading a tape during reclaim, I can
recreate it with a RESTORE command from another copy pool.

Indeed, I recently had a tape which was unreadable, rife with I/O
errors.  I simply entered the command 'Restore Volume...', and
voila, data back.  This is a delightful capability, much like
entering the fictional command 'fix problem'.  Exploiting ADSM
facilities means you are "covered" - life is made much easier
for you as an administrator.
