Issue/Introduction

 

Domainmanager.log on SDDC Manager: 

[c.v.e.s.o.model.error.ErrorFactory,dm-exec-1] VCF_ERRORS_GENERIC_INPUT_PARAM_ERROR Invalid parameter: port group <port_group_name> already exists
com.vmware.evo.sddc.orchestrator.exceptions.OrchTaskException: Invalid parameter: port group <port_group_name> already exists
        at com.vmware.vcf.common.contract.fsm.actions.impl.CreateVlanPortGroupAction.preValidate(CreateVlanPortGroupAction.java:144)

Environment

VMware Cloud Foundation 5.x

 

Cause

The option "USE ESXI MANAGEMENT VMK'S VLAN" is to let the admin decide whether to use ESXI management network for edge management or to use a different network for the same. If you go with ESXi management network, it tries to create a portgroup with same VLAN and portgroup name as ESXi management. But since the portgroup name already exists in the vCenter, this operation fails.

Resolution

Workaround:
When creating an Edge cluster for VI domain, if you select the option "USE ESXI MANAGEMENT VMK'S VLAN", please change the auto-populated portgroup name to something else so that there is no conflict.

If the environment is already in failed state, the partially deployed edge cluster should be removed using steps mentioned here: https://knowledge.broadcom.com/external/article/316110/vmware-cloud-foundation-nsxt-edge-clust.html.
