VMware vCenter Server

This article provides steps to create a VUM based cluster in the vCenter.

vCenter Server 7.x

vCenter Server 8.x

1. Create the Cluster Object

Log in to the vSphere Client.
Navigate to Home > Hosts and Clusters.
Right-click on the Datacenter (or folder) where you wish to place the cluster and select New Cluster.
In the Name and Location section, provide a name for the cluster.
Under the Cluster Features section, enable desired services such as vSphere DRS and vSphere HA.
Critical Step: In the Lifecycle Management section, ensure the checkbox "Manage all hosts in the cluster with a single image" is NOT selected.
Note: If this box is checked, the cluster will use the vLCM Image-based model.
Click Next and then Finish.

2. Verify Baseline Management

Select the newly created cluster in the inventory.
Click on the Updates tab.
Verify that the view displays Baselines and Baseline Groups.
If you see a prompt to "Setup Image," the cluster is correctly configured for baseline management. Do not click "Setup Image" unless you intend to convert to the image-based model.
