Hello. Timely subject for me as I have just begun using LTO-2s and LTO-1s. I was a big DLT users for years, still am but not with Tivoli.
Note.. assuming of course, one must remember that if you are compressing the Tivoli backup data on disk, when it gets to tape, even if you are compressing on tape, the tape won't compress very much??? Then on this note, I am curious why when I defined my LTO-2 and LTO-1 tape types, I specified LTO2C and LTO1C which should compress up to 400 GIGs for an LTO2 and 200 GIGs for an LTO1. But my q vol shows 200 GIGs and 100 GIGs used at FULL. Anyone else see this or comment.

The "EST CAP" is set when you define the DEVCLASS, probably 80GB in this case (see line for tape 000034). When data is then writtent to the tape, the EST Cap is updated to the ACTUAL capacity when the tape gets FULL. This may be higher or lower than the value in the defioned devclass. The tape will show the original EST Cap while FILLING until the amount of data exceeds this value. Then it increases as data is added until tape is FULL. The tapes that show FULL but have a pct Util less than 100 are mostly tapes had some of the data expired since they became FULL. David B.
