When one or more external disks are connected to a system, an External Disk Collection object
appears in both the tree pane and the overview pane of the OSM Service Connection. In both panes,
this object displays an alarm or yellow icon if alarms or degraded conditions exist on any of the
individual external disks contained within. You can expand the External Disk Collection icon in the
tree pane (but not in the overview pane) to select and monitor individual external disks.
