You can edit cluster properties to enable vSAN for an existing cluster.

About this task

After enabling vSAN on your cluster, you cannot move vSAN hosts from a vSAN enabled cluster to a non-vSAN cluster.

Prerequisites

Verify that your environment meets all requirements. See Requirements for Enabling vSAN.

Procedure

  1. Navigate to an existing host cluster in the vSphere Web Client.
  2. Click the Configure tab.
  3. Under vSAN, select General and click Edit to edit the cluster settings.
  4. If you want to enable deduplication and compression on the cluster, select the Deduplication and compression check box.

    vSAN automatically upgrades the on-disk format, causing a rolling reformat of every disk group in the cluster.

  5. (Optional) If you want to enable encryption on the cluster, select theEncryption check box, and select a KMS server.

    vSAN automatically upgrades the on-disk format, causing a rolling reformat of every disk group in the cluster.

  6. Click OK.

What to do next
