VEN Unpairing Details

During unpairing, the VEN performs the following actions. These actions are specific to the workload operating system.

Linux/AIX/Solaris

• Unpairs the VEN from the PCE.
  • Sends a "deactivate" message to the PCE.
• Restores the host firewall state to the requested or open state if no state is specified. Possible values of the state are:
  • Open: All ports are open after VEN uninstalls.
  • Saved: The firewall is restored to its state just before the VEN was installed.
• Uninstalls the illumio-ven package.
  • Removes program and data files.
  • Removes repo and GPG files and package.

Windows

• Unpairs the VEN from the PCE.
  • Sends a “deactivate” message to PCE.
• Stops all VEN services.
• Unregisters services from Service Control Manager.
• Restores Windows Firewall to requested state.
  • Open: All ports are open after VEN uninstalls.
  • Saved: Restore the firewall to its state just before the VEN was installed.
• Removes Program Files and ProgramData directories.
• Removes VEN registry keys.
• Removes Certificate.
• Unregisters VEN Event provider.

Support Report During Unpairing

When you unpair a workload, the VEN creates a local Support Report for diagnostic purposes in case you need a record of the VEN after it is uninstalled.

On Linux/Unix, the generated Support Report is saved to the /tmp directory. On Windows, the generated Support Report is saved to the C:\Windows\Temp directory. If a there is an existing Support Report in this directory, it will be overwritten with the new one.
