CESM case.setup "module command None purge" error on Grace (custom machine)

[Jiaojiao]

Describe your problem or question:
Hello, I am Jiaojiao Dong, a PhD student from Texas A&M University, I am a new beginner of CESM, and met a problem when I tried to setup a case, the details are as followings:

CESM version: 2.1.5
Machine: TAMU Grace HPC cluster

No changes to source code. Only modified config_machines.xml and config_batch.xml for the custom machine port (grace2).

Steps to reproduce:
1. Customized config_machines.xml and config_batch.xml for the Grace cluster (see key config_machines.xml content below).
2. Ran:
./create_newcase --case /scratch/user/jiaodong/test_grace2 --res f19_g16 --compset X --mach grace2
3. cd /scratch/user/jiaodong/test_grace2
4. ./case.setup
ERROR: module command None purge failed with message:
/bin/sh: None: command not found

This is the details of config_machines.xml


Still see the same error. Any suggestions on what might be causing this?

Thank you!

Is this the vista system? Here is what I have in config_machines.xml (for cesm3, but very similar)

Dear Jedwards,

Thank you very much for your reply. However, Grace runs on a Linux system. I have included some additional details in the attached figure for your reference.

Okay. I think that the point that I was trying to make is that you need to provide the init_path and cmd_path for (at least) the python and sh interfaces to the modules command.

Dear Jedwards,

Thank you for your help, I will try it.
