Cleaning Up the NSX-T Environment

If necessary, you can run a script to remove all NSX-T objects created by NCP.

The installation files include the following cleanup scripts:

• nsx_policy_cleanup.py - Use this script if NSX-T resources are created using Policy mode.
• nsx_cleanup.py - Use this script if NSX-T resources are created using Manager mode.

Before running the script, perform the following tasks:

• Stop NCP.
• Remove all resources that you created and are associated with the NCP-created objects. The script will fail if you do not delete those objects. For example, if NCP created a segment, and you created a distributed firewall (DFW) rule and group associated with the segment, you must delete the DFW rule and group, or remove the associations. Or if you attached VMs to the segment, you must delete the VMs or detach them from the segment.

For example:

python nsx_policy_cleanup.py --mgr-ip={nsx_mngr_ip} -u admin -p {password} -c {k8s_cluster_name} --no-warning -r

In some cases, the top-tier-router-id parameter must be be specified.
