Issue/Introduction

This article introduces Cluster health - vSphere Lifecycle Manager (vLCM) configuration check in the vSAN Health Service and provides details on why it might report a warning/error and how to fix the warning/error state.

Resolution

Q: What does the Cluster Health – vSphere Lifecycle Manager (vLCM) configuration check do?

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.

Q: What does it mean when it is in a warning state?

When it is in a yellow warning state, it means vLCM is not enabled. It is recommended users upgrade through vLCM instead of VUM.

Q: How does one troubleshoot and fix the error state?

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
