You must use the SnapCenter Add Host page to add hosts, and then install the plug-in packages. The plug-ins are automatically installed on the remote hosts. You can add a host and install the plug-in packages either for an individual host or for a cluster.
You cannot add a SnapCenter Server as a plug-in host to another SnapCenter Server.
If you install plug-ins on a cluster (WSFC), the plug-ins are installed on all of the nodes of the cluster.
Th Administration Guide contains more information on managing hosts.
When the host is added, the configuration checker operation is triggered automatically and provides alerts for recommendations, corrective actions, and notifications to resolve the issues.
