Enabling the Controller Disconnected Operation Mode on a Transport Zone

As covered in the introduction, CDO mode provides additional control plane resiliency during controller connectivity and controller cluster unavailability. With CDO mode enabled, VMs can be moved between ESXi hosts without data plane disruption, even if the whole controller cluster is down. In this recipe, we will show you how to enable CDO mode on a transport zone in NSX.

Getting ready

CDO mode is disabled by default in NSX. To enable CDO mode, the following prerequisites need to be satisfied:

• NSX is running on Version 6.3.0 or later
• The vSphere cluster has been prepared for NSX with VXLAN configured
• The NSX transport zone has been created
• The vSphere cluster has been added into the NSX transport zone

Note

For the universal transport zone, CDO mode can only be enabled from the Primary NSX Manager.
