Did you perhaps try the following (or similar)?
hdf5_merge gxx.file_0.h5 gxx.file_1.h5 gxx.h5
That will not work since hdf5_merge does not adjust the field IOProcs in
the files which tells the VisIt reader how many files to look for.
What works is eg.
hdf5_merge restart1/gxx.file_0.h5 restart2/gxx.file_0.h5
Instead you can use
hdf5_slicer --match '.*' --out3d-cube gxx.file_0.h5 gxx.file_1.h5 gxx.h5
from carpetiohdf5. Neither one does any merging of patches, they simply
copy datasets from one file to he other.
