HCX IX Mobility Agent deployment fails with vSphere Distributed Switch operation error

Products

• VMware HCX

Issue/Introduction

• VMware HCX IX Mobility Agent (MA) deployment fails during the Interconnect (IX) appliance configuration phase.
• The task fails with the following error string: "Cannot complete a vSphere Distributed Switch operation for one or more host members"
• You can notice below error even : 
  "vDS operation failed on host <host_IP>, got (vmodl.fault.invalidArgument) exception."
"The host is in a different datacenter (DC_Name) than the vCenter VDS datacenter (DC_Name)."
  
  
• Review of vCenter Server logs may indicate an invalidArgument exception during the vDS operation.
  
   
  
  
• This symptom occurs when an IX appliance attempts to interface with a vSphere Distributed Switch (vDS) that is not associated with the host's Datacenter or Cluster.

Environment

VMware HCX

Cause

• This issue occurs when an IX appliance attempts to interface with a vSphere Distributed Switch (vDS) that is not associated with the host's Datacenter or Cluster.
• When a Compute Profile includes multiple Datacenters or Clusters that do not share the same Distributed Virtual Switch (vDS), the IX appliance may attempt to attach to a vDS that is not physically or logically reachable from the cluster where the appliance is deployed.

Resolution

1. Log in to the HCX Manager 443 UI.

2. Navigate to Infrastructure > Interconnect > Compute Profiles.

3. Create individual Compute Profiles for each cluster or datacenter that utilizes a unique or non-shared vDS.

4. During the Select Clusters step of the wizard, limit the scope to only those clusters attached to the intended DVS.

5. Create a new Service Mesh using the newly created, cluster-specific Compute Profile.
