vSphere 6.7 upgrade vSAN 6.6 to 6.7 – pt.4

 

If the virtual infrastructure in use is configured with vSAN, after completing the upgrade of both vCSA and ESXi hosts to version 6.7, also vSAN should be upgraded to latest version.

After the upgrade of vSphere components (vCSA and ESXi hosts), the vSAN cluster’s Summary tab displays a warning message related to Disk format version.

vSAN cluster checks before the upgrade

Before upgrading the vSAN cluster, some checks must be performed to avoid possible issues or data loss during the upgrade process.

Select the vSAN cluster and go to Configure tab. Click on Disk Management under vSAN area and verify that vSAN Health Status is reported as Healthy for all disks and disk groups configured.

In this area you can check running tasks or perform a synchronization before proceeding with the upgrade by clicking Resync Throttling.
