Unable to create Edge Cluster through SDDC Manager 5.2.1 with error during validation of "Supplied compute cluster to host edge(s) is not DVPG compliant cluster"

Products

• VMware SDDC Manager

Issue/Introduction

The error seen within SDDC Manager for the "Add Edge Cluster" creation is  "Supplied compute cluster to host edge(s) is not DVPG compliant cluster." for the "Validate if specified vSphere cluster is DVPG compliant".

Environment

SDDC Manager 5.2.1

Cause

DVPG was a new feature as part of SDDC Manager 5.1.   VCF 5.1 and beyond, the VM_MANAGEMENT port group will be required/created to enable the traffic isolation between management VMs (such as SDDC Manager, NSX Manager, and vCenter) and ESXi Management VMkernel interfaces.

If Edge clusters were created prior to VCF 5.1, they will not have the required VM_MANAGEMENT port group.  Thus when creating a new Edge cluster, that now requires the VM_MANAGEMENT port group, the Edge cluster validation fails as it does not see that port group on the compute cluster.

Resolution

Apply the config-drifts in the upgraded VCF 5.2.1 environment.

It needs to run the config-drifts so the VM_MANAGEMENT port group will be created for the existing Edge Clusters to enable traffic isolation.

Once Config-drifts are successfully applied, the VM_MANAGEMENT port group will be created on the VI domain for the existing Edge Clusters.

To apply the configuration drifts within the SDDC-Manager UI:

1. Go to VI domain, click "Updates" tab, look for "Available Configuration Updates", and apply the configuration drifts.

2. Retry the Edge cluster creation, if that still fails a reboot of the SDDC manager appliance may be needed.
