Did you implement the getGridCoverageNames method? I believe that's what
GeoServer uses to show the GUI.
Does it work if you try to configure the single HDF5 file?
But yes, it may well be that there is some unintended contamination with
StructuredGridCoverage2DReader, while we do not
mandate implementing that interface for multi-coverage data, the reality is
that right now all officially supported multi-coverage
sources also do implement that interface (netcdf, image mosaic) so there
might be some unintended hiccup along the way (either
in the mosaic, or in geoserver), and the only mosaic of multiple coverages
that we tested is the netcdf one.
