When vSAN ESA is enabled, this health check will be triggered and performed. There are two ways to upgrade ESXi hosts - VUM(VMware Update Manager) or vLCM(vSphere Lifecycle Manager). For a vSAN ESA cluster, vLCM is the only supported method for upgrading the cluster via a Single Image. It will be performed when doing HCI quick start workflow, vSAN Configuration and VUM upgrade precheck. This health check was introduced to assist users to check vLCM is enabled.
When it is in a yellow warning state, it means vLCM is not enabled. It is recommended users upgrade through vLCM instead of VUM.
When creating a cluster, please check "Manage all hosts in the cluster with a single image" as seen below.
If you are already done creating a cluster, please go to vSAN ESA Cluster → Updates → Image → Setup Image or Import Image
