There is a limitation of 5.3G.  You can use the undocumented command SHOW LVMFA
to see the limitation for that and for the size of the data base.  The
limitation is
the same for all current versions of the ADSM/TSM server.  It might change in
the
future.

IC15376 is not quite accurate (although it does mention 5G not 5.5G).
IY09200 is accurate on the 5416K value, although the difference between the
5416K and the 5420K is not because of control information, only with how
calculations were performed that store data structures in a certain fixed
area in the first 1M area of each DB and LOG volume.
