Hi,
Its on you device class definitions.
Device Class Name: LTO_PRIM
Device Type: LTO
Format: DRIVE
You can change the default from "drive" to ultrium 4c for forced compression.
This will only help if you data is not already compressed (being compressed
data by nature like .jpg/zip etc or due to host based compression).
(from help upd dev)

Where do I enable compression for LTO4 tapes/drives in a 3584 library? The
