I just check the hdf5 file and I found that the  Corner Coordinates of one
subdataset is not the same as that of the hdf5 file.

I use "gdalinfo aa.he5" and the coordinate is :
----------------------------
 Upper Left  (    0.0,    0.0)
Lower Left  (    0.0,  512.0)
Upper Right (  512.0,    0.0)
Lower Right (  512.0,  512.0)
Center      (  256.0,  256.0)
--------------------------------
and one of the subdatasets if named
[HDF5:"d24.he5"://HDFEOS/GRIDS/ColumnAmountO3/Data_Fields/GhostColumnAmountO3].
Then I got its coordinate is :
---------------------------
Upper Left  (    0.0,    0.0)
Lower Left  (    0.0,  720.0)
Upper Right ( 1440.0,    0.0)
Lower Right ( 1440.0,  720.0)
Center      (  720.0,  360.0)
---------------------------
 Does that mean the gdal can not handle the hdf5 data?
