Looks like I figured out the problem. When the input data is being downloaded inside the site or the input data server, the following data is followed by the following path:
/home/user/inputdata/cesm2_init/f.e21.FWsc2000climo.f09_f09_mg17.cesm2.1-exp011.001/0003-01-01/f.e21.FWsc2000climo.f09_f09_mg17.cesm2.1-exp011.001.cam.i .0003-01-01-00000.nc
But inside your site, this path has a v2 both inside the path and the file name.
/cesm/inutdata/cesm2_init/f.e21.fwsc2000Climo.f09_f09_mg17.cesm2.1-exp011.001_v2/0003-01-01-01/f.e21.FWsc2000climo.f09_f09_mg17.cesm2.1-exp011.001_v2.cam.i.0003-01-01-00000.nc
However, what can be done? How to continue downloading input data?
