Christo - Feel free to browse http://people.bu.edu/rbs/ADSM.QuickFacts
          for accumulated real-world explanations of various TSM messages.
In this case:

ANS9281E Space management kernel extension is downlevel from the server program.
        Encountered when a new level of the HSM software was installed over a
        live HSM system - a bad thing to do.  See: installfsm

The Space Manager is a *SM invention.  The kernel extension is loaded by the
/etc/rc.adsmhsm script (a symlink to ADSM's /usr/lpp/adsm/rc.adsmhsm), as
invoked by /etc/inittab's "adsmsmext" entry.  You can see if ADSM HSM is
installed by doing 'lslpp -l "adsm*"' in AIX, or something similar on other
platforms.  Don't expect a TSM install to automatically remove ADSM software,
which is to say that your system was probably running HSM before, and that
the TSM 3.7 you installed is probably there in addition to the old ADSM code.
When installing a TSM client, always be careful to pick the components you
really want - don't automatically install everything just because it's there.
