5.7 TB Seems to be pretty normal to me. As the name of the storage pool
implies video content, I think you won`t get much more compression with
LTO enabled hardware compression on video files with a decent codec.

Why it is LTO2 capacity reads differently than 3590's. My 3590's report 40GB
when filling and at least 40GB when full. K tapes read 20/40 and LTO2's
200/400. So why wouldn't it show at least 400?
Is this a TSM, LTO or some other issue causing this?
Is a tape reporting 215GB when full really
sending it to the ITSM server?

It also makes no sense if estimated capacity is 400GB, and the
drive is
capable of supporting that, it only reports 200.
Sure it does... The native capacity of LTO2 is 200 GB (plus or minus
a tad, depending upon the actual length of the individual tape).
Think of a tape as containing 200

In my experience, the label command will not change the density of the

Generally speaking, rewriting a tape from its beginning, as relabeling
does, is the only opportunity to change a tape's density. This has
been true of computer tapes since the early days of open reel tapes.

1) did they tell you the tape capacity is 80G after compression or
