Issue/Introduction
Symptoms:
When upgrading to VMware NSX for vSphere 6.3.0 with a HW VTEP in the environment, you may experience this symptom:
- Upgrade is halted
- You see the error similar to:
Cannot continue upgrade due to errors: "(1)" Hardware Gateway(s)found in the system. Unable to proceed with the upgrade. Please contact VMWare Support to continue. Please correct before proceeding.
Environment
VMware NSX for vSphere 6.3.x
VMware NSX for vSphere 6.1.x
VMware NSX for vSphere 6.2.x
Cause
This issue occurs because there is a HW VTEP configuration present. NSX for vSphere 6.3.0 supports only TLS 1.2 secure connections in the control plane. HW VTEPs that do not support TLS, thus cannot connect to the NSX Controllers. The upgrade has been blocked to avoid disconnecting these HW VTEPs and impacting network traffic.
