[Optional] Upgrade the vSAN on-disk format version to take advantage of features that are available only in the later versions.

  • The upgrade may cause temporary resynchronization traffic and use additional space by moving data or rebuilding object components to a new data structure.

Prerequisites

  • ESXi and vCenter Upgrades are completed

  • Verify that the disks are in a healthy state. Navigate to the Disk Management page to verify the object status.

  • Verify that your hosts are not in maintenance mode. When upgrading the disk format, do not place the hosts in maintenance mode.

  • Verify that there are no component rebuilding tasks currently in progress in the vSAN cluster. For information about vSAN resynchronization, see vSphere Monitoring and Performance

Procedure

  1. Navigate to the vSAN cluster.
  2. Click the Configure tab.
  3. Under vSAN, select Disk Management.
  4. 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 are displayed in the Disk pre-check status text box.
  5. Click Upgrade.
  6. Click Yes on the Upgrade dialog box to perform the upgrade of the on-disk format.

Results

vSAN successfully upgrades the on-disk format. The On-disk Format Version column displays the disk format version of storage devices in the cluster
