Symptoms:
In TCA 2.3, there is an issue which causes a port group reconfigure action to be triggered when cell site hosts are picked up for provisioning in a domain. When this reconfigure action is triggered, if there are any disconnected or unreachable hosts attached to the VDS then the reconfigure fails, thereby failing the provisioning of the hosts that were picked up and they are marked as FAILED.
This issue mainly happens if any of the port groups have vmnics that are marked to be set as unused uplinks.
Error:
Failed to reconfigure the vds: hostname reason: (vim.fault.DvsOperationBulkFault) {
dynamicType = <unset>,
dynamicProperty = (vmodl.DynamicProperty) [],
msg = 'Cannot complete a vSphere Distributed Switch operation for one or more host members.',
faultCause = <unset>,
faultMessage = (vmodl.LocalizableMessage) [],
hostFault = (vim.fault.DvsOperationBulkFault.FaultOnHost)
