Illumio Core 25.2.10 Administration Guide

Effects of Unpairing VENs

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 source.

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.
