Looking in the "Magstar MP 3575 Tape Library Dataserver: Multiplatform Implementation"
Redbook, p.136, the hardware compression settings are controlled from AIX. The default
setting is compression "on". Page 146 indicates that format=3570C uses compression.
However it SHOULD be done, the fact remains that Nancy is not getting any compression.
Someone may have modified the device settings. By modifying the device settings and
changing ADSM to format=drive (this is not really necessary, but useful for adding XLC
cartridges), this should give her what she wants.

Wait a minute...TSM is supposed to set tape drive characteristics, among the
drives that it directly supports, per administrative specifications: it should
not be necessary to forcibly alter drive characteristics with the product.
Doesn't the DEVclass FORMAT=3570C take care of this?
