I feel like I'm getting incorrect information from available_media and
from getting reports from the gui on how much space is available on my
tapes.

I'm running 4.5 fp3 on solaris with an lto-1 autoloader with 9
tapes. These tapes hold 100GB uncompressed, and I'm not using compression
on any of my backups yet some of the output from available_media shows
well over 100gb on a tape. Tape 2771L1 says it has 247 gb if my math is
correct. That wouldn't even be possible if I was using compression.

I made the mistake of doing ALLOW_MULTIPLE_RETENTIONS_PER_TAPE before I
realized the ramifications, and now tape 2777L1 thinks it has multiple
retentions on it but I can't seem to find the offending image and move or
get rid of it. I think all the images on it are of the same retention
level.

Also, tape 2773L1 which claims to have 181GB on it really only has two
images that couldn't add up to more than 50GB, yet it says it's full. 

Does anybody have a better idea than me as to what is going on here?
