Is CESM1.0.1 F_2000 did not support T85_T85 or It is my fault?

Hello,
I tried to creat a case with -res T85_T85 -compset F_2000, but it is failed.
By the way, the -res T42_T42 and T31_T31 are work well.
Is there anyone who knows the reason?

CSEG and Liaisons
If you look in the file models/atm/cam/bld/namelist_files/namelist_defaults_cam.xml you will find the default values for ncdata in the elements. The T85 file which is distinquished by the attribute hgrid="128x256" has an associated date given by the attribute ic_ymd="901". In other words, there is no January 01 dataset provided, just one for September 01. This means you need to explicitly set the value of ncdata for your run since a default value will not be found. It may be possible to start the run from jan 01 using the sep 01 dataset, so that would be my first recommendation.

As an aside the reason that there aren't so many initial files provided for Eulerian dycore is because that is no longer the main supported dycore in CAM. It is now supported mainly for the purpose of low resolution paleoclimate runs (T31 in particular).
