Hello everyone!
I am currently using CESM2.2.0 and attempting to branch from CMIP6 data. I have obtained the CMIP6 restart file, which is named "b.e21.BHIST.f09_g17.CMIP6-historical.001.rest.1980-01-01-00000". Here is my operational process:
1、Create new case
/work/software/cesm/2.2.0_openmpi2020/cime/scripts/create_newcase --case ~/ymt/case_cesm2/control --compset BHIST --res f09_g17 --run-unsupported
2、change pelayout
./xmlchange NTASKS_CPL=90,NTASKS_ATM=90,NTASKS_LND=60,NTASKS_ICE=30,NTASKS_OCN=30,NTASKS_ROF=60,NTASKS_GLC=90,NTASKS_WAV=90,NTASKS_IAC=1,NTASKS_ESP=1
./xmlchange ROOTPE_ICE=60,ROOTPE_OCN=90
./case.setup
3、
./xmlchange STOP_OPTION=nmonth
./xmlchange STOP_N=2
./xmlchange RUN_TYPE=branch
./xmlchange RUN_REFCASE=b.e21.BHIST.f09_g17.CMIP6-historical.001
./xmlchange RUN_REFDATE=1980-01-01
./xmlchange JOB_WALLCLOCK_TIME=96:00:00
4、copy restart to run dir
cp /archive/users/lisl01/ybj/restart/1980-01-01-00000/* /work/users/lisl01/cesm/CMIP6_branch.001/run/
5、
./case.build --skip-provenance-check
6、
./case.submit
ERROR: RUN FAIL: Command 'mpirun -np 240 /work/users/lisl01/cesm/CMIP6_branch.001/bld/cesm.exe >> cesm.log.$LID 2>&1 ' failed

My question is, is this due to an issue with my operating method, or is it a compatibility issue that requires the use of CESM2.1? If it is possible to do this with CESM2.2, what should I do?

Thank you
