6 Uninstalling VNFM

Note:

VNFM uninstallation requires manual intervention and impacts existing configurations. Proceed only if you intend to completely remove the VNFM.

Following are the steps to uninstall VNFM:

1. Log in to your OpenStack cloud platform using appropriate credentials.
2. Delete the VNFM Stack: Within OpenStack, locate the management interface for managing deployed stacks. Identify the VNFM stack and initiate its deletion process.
3. Delete Associated Volume (Optional): After removing the VNFM stack, an associated volume containing VNFM data will remain. Deleting this volume permanently removes all VNFM data.

Note:

The volume cannot be restored. If you want to save data for future VNFM deployments, don't delete the volume.

Preserving Configurations for Redeployment:

If you intend to reinstall VNFM in the future and require current data, save the associated volume during the uninstalling procedure. This volume can then be used during a new VNFM deployment to restore your previous settings.

Security Considerations for Redeployment:

The VNFM volume stores sensitive operational and configuration information. When reinstalling VNFM, the administrator is responsible for attaching this volume to the new instance. Ensure that data on the volume is only accessed through the VNFM application.
