[VMC] Configuring Hybrid Linked Mode (HLM) from Cloud SDDC

Products

• VMware Cloud on AWS

Issue/Introduction

Prerequisites and recommendations for configuring HLM from a VMC on AWS SDDC

Environment

VMC on AWS

Cause

• It is now recommended to configure HLM directly from the VMC on AWS SDDC instead of using the vCenter Cloud Gateway Appliance (VCGA). 
• The VCGA will be completely deprecated for use with HLM post SDDC version 1.24. 
• The VCGA is no longer being updated or patched. 
• VMware Cloud Gateway Notice of Deprecation FAQ

Resolution

Before configuring HLM, review the prerequisites:

• The on-premise vSphere environment must be vSphere 6.5 Patch d or later. 
• The on-premise vSphere environment cannot be at a higher version than the SDDC vSphere version. 
• The SDDC vSphere version can be verified using the Correlating VMware Cloud on AWS SDDC Versions With Their vSphere Components documentation. 
• Verify the correct firewall ports are open in both environments.
• The network connectivity for HLM can be validated by using the VMware Cloud Console Connectivity Validator. 
• The complete list of prerequisites can be found in the Hybrid Linked Mode Prerequisites documentation. 

If the prerequisites and recommendations have been followed and HLM is failing to link, open a ticket with support.
