No data on these tapes.  They are scratch 3592s.  They were in the

characters and checked them back in to tsm as scratch tapes.  tsm
still sees them as 6 characters.  Do I have to physically removed
them from the library, reinventory to get rid of the 6 characters,
then reinsert them to pick up the 8 characters?

IBM Technote 1217789 will be a good reference for your purposes.
Particularly see the last paragraph.
