[gpfsug-discuss] LTFS/EE - fixing bad tapes..

I'm kinda curious... I've noticed a few message on this subject -- so I 
went to the doc....

The doc seems to indicate there are some circumstances where removing the 
tape with the appropriate command and options and then adding it back will 
result in the files on the tape becoming available again...  But, of 
course, tapes are not 100% (nothing is), so no guarantee.   Perhaps  the 
rigamarole of removing and adding back is compensating for software glitch 
(bug!)  -- Logically seems it shouldn't be necessary -- either the tape is 
readable or not -- the system should be able to do retries and error 
correction without removing --  but worth a shot.

(I'm a gpfs guy, but not an LTFS/EE/tape guy)
