Storage policies assigned to the Supervisor manage how such objects as a control plane VM, vSphere Pod ephemeral disk, and container image cache are placed within datastores in the vSphere storage environment. As a vSphere administrator, you typically configure storage policies when enabling the Supervisor. If you need to make any changes in the storage policy assignments after initial Supervisor configuration, perform this task. You can also use this task to activate or deactivate file volume support for ReadWriteMany persistent volumes in TKG clusters.

Generally, the changes you make to the storage settings apply only to new objects in Supervisor. If you use this procedure to activate file volume support in TKG clusters, you can do it for the existing clusters.

Prerequisites

If you plan to activate file volume support on TKG clusters for persistent volumes in ReadWriteMany mode, follow prerequisites in Creating ReadWriteMany Persistent Volumes in vSphere with Tanzu in the vSphere with Tanzu Services and Workloads documentation.

Procedure

  1. In the vSphere Client, navigate to Workload Management.
  2. Click the Supervisors tab and select the Supervisor to edit from the list.
  3. Click the Configure tab and click Storage.

  4. Change storage policy assignments for the control plane VMs.
    If your environment supports a vSphere Pod, you can also change storage policies for an ephemeral virtual disk and container image cache.
    Option Description
    Control Plane Node Select the storage policy for placement of the control plane VMs.
    Pod Ephemeral Disks Select the storage policy for placement of the vSphere Pods.
    Container Image Cache Select the storage policy for placement of the cache of container images.
  5. Enable file volume support to deploy ReadWriteMany persistent volumes.
    This option is available only if your environment has been configured with vSAN File Service. See Enable vSAN File Service.
    File volume option enabled.
