I tried:

#PETSc Option Table entries:
-dm_view hdf5:res.h5
-snes_monitor_residual hdf5:res.h5::append

And see this:
 ...
#End of PETSc Option Table entries
There is one unused database option. It is:
Option left: name:-dm_view value: hdf5:res.h5

And, of course, I get the same bad h5 file as before. In other codes I have
had to add code. I tried simply adding

ierr = DMViewFromOptions(ctx->dm,NULL,"-dm_view");CHKERRQ(ierr);

before the solve, but that did not change anything (same bad h5 file) other
than remove the 'options left' warning.

I tried to clone the code that I use for printing vectors manually by
adding this before the solve:

      ierr = DMViewFromOptions(ctx->dm,NULL,"-dm_view");CHKERRQ(ierr);
      ierr =
PetscOptionsGetViewer(PETSC_COMM_SELF,NULL,"-snes_monitor_residual",&viewer,&fmt,&flg);CHKERRQ(ierr);
      if (flg) {
ierr = PetscViewerPushFormat(viewer,fmt);CHKERRQ(ierr);
      }

But got this error in the solve:
