Working with Impact Analysis in Data Center Operation

Configure the inventory, including the position of your host servers in the rack layout, set up the power path down to server level, and associate the power source with devices receiving alarms.
Associate the servers in the layout with your virtual hosts by dragging a server from the Unassociated Devices pane over the server representing it in the layout.
Review the virtual machine setup. The V icons on the servers in the layout indicate if the hosts have been associated, and if an impact occurred.
