vSAN version mismatched

I have a vSAN with 3 nodes connected to vcenter 6.7. The info provide to me is the nodes ESXi version are 6.0U3 but the vsan version is 5.5. This puzzled me. As per my knowledge vsan version follows the ESXi version. 

Now the web client the vSAN tab unable to display anything. 

Any ESXCLI command i could run to check on the vSAN version, the on-disk format version?

Thank you.

there's a health check for that from the top of my head, so just go to vSAN health and look at the "disk format version" check. If it is not on the correct level, go to: your cluster > Configure > vSAN > Disk Management. Disk management should also show you the version you are on by the way.

 you can use esxcli vsan storage list to find the disk format version

$esxcli vsan storage list

However for earlier versions of vSAN I am not sure if we list the disk format version

disk format version in conjuntion with ESXi build determines vSAN version

see KB https://kb.vmware.com/s/article/2148493 where we match dsk format versions to ESXi versions 

it also provides an interop matrix of what versions are supported with what version of ESX

so if you were at 6.0U3 you;d have to have disk format verson 2 or 3
