The mNode Settings tab in the NetApp Element Configuration extension point allows you to configure settings that are used for the QoSSIOC service. After you have configured a valid management node, these settings become the default. You can edit these settings to update credentials or clear these settings for a new management node.
For Linked Mode, the NetApp Element Plug-in for vCenter Server registers all vCenter Servers using the management node settings you provide on a single vCenter Server.
