  CARRScriptExecutionTask - [nsx@6876 comp="nsx-manager" level="WARNING" subcomp="upgrade-coordinator"] Failed to run the script: nice -n 10 sudo /opt/vmware/upgrade-coordinator-tomcat/bin/uc_helper.py carr-script -d -l. Exit code: 1, Output: [Errno 2] No such file or directory: '/image/carr/carr-script-pub/carr-script'

Environment

VMware NSX 4.2.4

Cause

During the upgrade to NSX 4.2.4, the system automatically starts running the CARR script. If the /image/carr/carr-script-pub folder is missing, the system cannot proceed with the precheck and installation because it cannot run the CARR script.

Resolution

Workaround:

1. Connect to the NSX Manager console using SSH as the root user.
2. Find the CARR script at /repository/4.2.4.0.0.25410638/carr/carr-script-pub.tar.gz
3. Create the folder /image/carr/carr-script-pub using the following command:

   mkdir -p /image/carr/carr-script-pub/

4. Extract (untar) the file into the folder /image/carr/carr-script-pub/ using the following command:

   tar -xzf carr-script-pub.tar.gz -C /image/carr/carr-script-pub/

5. Repeat steps 1 through 3 on the other two NSX Manager nodes.
6. Run the pre-check again from the SDDC Manager interface.
