Atul Since VisIt did not try any file readers (and there should be several that are using HDF5), maybe the problem is that you are using a newer HDF5 binary format that is not understood by the older HDF5 library that VisIt might be using? Do you have access to a tool called "h5format_convert", and if so, can you apply it to your HDF5 files?
