Issue/Introduction
The Unsupported host version check in the vSAN Health Service verifies the ESXi version on each host in the stretched cluster.
If this health check is not green (OK), the vSAN stretched cluster has configuration errors that affect its operation.
If this health check is not green (OK), the vSAN stretched cluster has configuration errors that affect its operation.
Environment
VMware vSAN 6.0.x
VMware vSAN 6.2.x
VMware vSAN 6.1.x
VMware vSAN 6.2.x
VMware vSAN 6.1.x
Resolution
The vSAN stretched cluster is a new feature introduced in vSphere 6.0 Update 1. An ESXi host running an earlier version does not form a stretched cluster properly. This check verifies that all hosts in the data sites are running vSphere 6.0 Update 1 or newer version.
To view the list of ESXi hosts, run the esxcli vsan cluster get command. If you run the command on the witness host, the local node type appears as WITNESS.
For example:
[root@:~] esxcli vsan cluster get

You can collect the list of node information and preferred fault domain by querying CMMDS from a host.
For example:
[root@:~] cmmds-tool find -t NODE
owner=00000000-0000-0000-0000-000000000000(Health: Healthy) uuid=558c3ca0-1a32-1527-2847-020001469e57 type=NODE rev=0 minHostVer=0 [content = (i2 i1 i0 i1 i0)], errorStr=(null)
