The Issue

When you have attached a vSphere Storage Policy to your vSphere Namespace, and tried to create a cluster using the Storage Policy Name, you find it will fail with an error such as:

Error from server (storage class is not valid for control plane VM: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl', 

storage class is not valid for worker VMs: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl', 

storage class Tanzu Storage Policy under spec.settings.storage.defaultClass is not valid: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl'): error when creating "cluster.yaml": 

admission webhook "default.validating.tanzukubernetescluster.run.tanzu.vmware.com" denied the request: storage class is not valid for control plane VM: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl', 

storage class is not valid for worker VMs: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl', 

storage class Tanzu Storage Policy under spec.settings.storage.defaultClass is not valid: StorageClass 'Tanzu Storage Policy' is not assigned for namespace 'deanl'

When you look at the vSphere namespace, the Storage Policy is attached.

And example of the erroneous Tanzu Cluster definition YAML:

apiVersion: run.tanzu.vmware.com/v1alpha1
kind: TanzuKubernetesCluster
metadata:
  name: deanl-cluster
  namespace: deanl
spec:
  distribution:
    version: v1.18.5
  topology:
    controlPlane:
      class: best-effort-small
      count: 1
      storageClass: "Tanzu Storage Policy"
    workers:
      class: best-effort-small
      count: 1
      storageClass: "Tanzu Storage Policy"
  settings:
    network:
      cni:
        name: calico
    storage:
      defaultClass: "Tanzu Storage Policy"
