TSM certainly sets the drive attributes to effect hardware compression.
The 'C' at the end of the DEVclass FORMAT spec incites the server to
set that drive attribute. In AIX, the drive attributes currently in effect
can be listed via 'lsattr -EHl rmt1'. Solaris must have something similar,
but that's beyond my experience.
