HCX - Resync service mesh failed with the error "Cannot complete a vSphere Distributed Switch operation for one or more host members"

Products

• VMware HCX

Issue/Introduction

• An HCX Compute Profile is created with multiple datacenters selected in the "Service Resources".
• The following error is observed in /common/logs/admin/app.log:

java.lang.RuntimeException: Interconnect Service Workflow interconnectConfigureMA failed. Error: Adding Mobility Agent Host failed. Adding host to DVS <DVS NAME> failed. Error : Cannot complete a vSphere Distributed Switch operation for one or more host members.

• On vCenter tasks, the task fails while adding the MA (Mobility Agent) host with the error message:  "The host is in a different  datacenter <name> than the vCenter VDS datacenter <name>."

Environment

HCX 

Cause

This limitation is explained in the Compute Profile Considerations and Concepts, where deployment cluster and service clusters must be confined to a single data center, as DVS cannot be used across different datacenters.

Resolution

• Using a single HCX service mesh across multiple datacenters is not supported.
• If vCenter contains multiple datacenters, create a new HCX Compute Profile selecting the deployment cluster and service cluster from the same datacenter, then deploy the service mesh.
