Mike,

DGN files can contain a variety of geometry types in one layer.  Shapefiles
can only have one geometry type in a file.  You will need to do a translation
for each type of geometry you want to capture.  Something like:

/usr/local/bin/ogr2ogr -skipfailures -f "ESRI Shapefile" -nlt POLYGON \
   /susepool2/xxxpolygon.shp /test.dgn
/usr/local/bin/ogr2ogr -skipfailures -f "ESRI Shapefile" -nlt LINESTRING \
   /susepool2/xxxline.shp /test.dgn
/usr/local/bin/ogr2ogr -skipfailures -f "ESRI Shapefile" -nlt POINT \
   /susepool2/xxxpoint.shp /test.dgn

PS. this is really an OGR question and would be better addressed to the
gdal-dev mailing list.

Good luck,
