Hi,
Are you using -n with h5dump?
Here is an output of h5dump with -n flag for one of the NPP files we work with:
h5dump -n
SVM16_npp_d20120724_t0927227_e0928468_b03831_c20120730184331707971_XXXX_XXX.h5
HDF5
"SVM16_npp_d20120724_t0927227_e0928468_b03831_c20120730184331707971_XXXX_XXX.h5"
{

dataset /Data_Products/VIIRS-M16-SDR/VIIRS-M16-SDR_Aggr
dataset /Data_Products/VIIRS-M16-SDR/VIIRS-M16-SDR_Gran_0
}
}
Please try
h5dump -H <file_name>.h5
to get the HDF5 objects stored in the file and their attributes
or just
h5dump <file_name>.h5
to get all content (be aware this one will print all datasets values!)
