To check the compliance status of the objects in your inventory against selected baselines and baseline groups, you must first attach the respective baselines and baseline groups to the objects.

You attach baselines and baseline groups to individual hosts or objects that contain hosts, such as clusters, data centers, and vCenter Server instances. In the vSphere infrastructure hierarchy, the baseline and baseline groups that you attach to container objects are also attached to the child objects. For example, if you attach a baseline or baseline group to a folder, the baseline or the baseline groups is inherited by all the objects in the folder, including subfolders.

You cannot use vSphere Lifecycle Manager to update the hosts in a cluster that uses a single vSphere Lifecycle Manager image. For more information about using vSphere Lifecycle Manager images to manage hosts in clusters collectively, see Using vSphere Lifecycle Manager Images.


  • If you want to attach a baseline or a baseline group to a cluster, verify that the cluster is not configured to use a single image.
  • Required privileges: VMware vSphere Lifecycle Manager.Manage Baselines.Attach Baseline.


  1. In the vSphere Client, navigate to the vSphere Lifecycle Manager compliance view for an individual host or a container object.
    1. Navigate to a host, cluster, or a container object.
    2. Click the Updates tab.
  2. Select Hosts > Baselines.
  3. In the Attached Baselines pane, click Attach > Attach Baseline or Baseline Group.
    The Attach dialog box opens.
  4. Select one or more baselines or baseline groups and click Attach.
    If you select a baseline group, all the baselines in it are attached to the object.
    The selected baselines or baseline groups are attached to the object. They appear on the list in the Attached Baselines pane. If the selected object is a container object, the selected baselines or baseline groups are attached to all the child objects.

What to do next

Scan the selected object against the attached baselines.
