Environment

VMware NSX 4.X

VCF 9

Cause

Some Transport Zone Profiles may not have a property profile_id populated. The script published on the documentation page doesn't handle these objects properly.

Resolution

This issue is resolved in VCF 9.0.2, available at Broadcom downloads.

If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.

Workaround:

1. Download the patched script attached to this article: uens-enable-423.tgz
2. SCP the file to the NSX Manager as root in /root (same node as previous run).
3. SSH the NSX Manager as root.
4. Change directory: cd /opt/vmware/migration-coordinator-tomcat/bin
5. Patch the script with the newer version: tar -xvzf /root/uens-enable-423.tgz
6. Correct file permissions: chown -R umc:umc uens-adoption
7. Change directory: cd uens-adoption/config/
8. Follow instruction in the README file to use run the enable_uens.py with the same config file used last time.
