If you want to set up a host to use the same configuration as a reference host, you can attach the host to a profile. You can also attach a cluster to a profile.
Profiles can also be attached to a cluster. In order to be compliant, all hosts within an attached cluster must be configured according to the profile. Hosts are not automatically configured in accordance to the host profile that is attached with the cluster when it is added to the cluster. When a host is added to a cluster that is attached to a profile, the host is automatically attached to the profile.
You can attach a host or cluster to a profile from:
Host Profiles main view
Host's context menu
Cluster's context menu
Cluster's Profile Compliance tab
