Upgrade the VMware vSAN disk format (vSAN storage option only)

Use this procedure to upgrade the VMware vSAN disk format.

Prerequisites

  • Verify that you are using the updated version of VMware vCenter Server.
  • Verify that you are using the latest version of VMware NSX-T Edge Gateway hosts.
  • Verify that the disks are in a healthy state. (In the vSphere Client, navigate to Host and Clusters, highlight your PowerFlex management controller cluster, then click on the vSAN tab, and click on physical disks to verify the object status in the right hand column.
  • Verify that your hosts are not in maintenance mode. When upgrading the disk format, do not place the hosts in maintenance mode. When any member host of a vSAN cluster enters maintenance mode, the member host no longer contributes capacity to the cluster. The cluster capacity is reduced and the cluster upgrade might fail.

Steps

  1. Navigate to the vSAN cluster in the VMware vSphere Client.
  2. From Host and Clusters, highlight your PowerFlex management controller cluster and click the Configure tab on the right hand pane.
  3. Under vSAN, select General.
  4. Under On-Disk Format Version, click Pre-Check Upgrade.

    The upgrade pre-check analyzes the cluster to uncover any issues that might prevent a successful upgrade. Some of the items checked are host status, disk status, network status, and object status. Upgrade issues appear in the disk pre-check status text box.

    The pre-check should be run before initiating on-disk format upgrade task.

  5. Under On-Disk Format Version, click Upgrade.
  6. Verify the check box beside Allow Reduced Redundancy is cleared.
  7. Click Yes on the Upgrade box to perform the upgrade of the on-disk format.
