Dell PowerVault MD3220 Owner's Manual page 219

In the Table view, every managed storage array is listed once, regardless of the
number of attachments it has in the Tree view. After the storage array has
been contacted by MDSM, an icon representing its hardware status appears.
Hardware status can be Optimal, Needs Attention, or Fixing. If, however, all
of the network management connections from the storage management
station to the storage array shown in the Tree view are Unresponsive, the
storage array status is represented as Unresponsive.
In the EMW Status Bar and the AMW Status Bar, the icons also have these
behaviors:
• Hold the mouse over the icon in the EMW Status Bar and the AMW
Status Bar to show a tooltip with a brief description of the status.
• The icons for the Needs Attention status and Unresponsive status appear
in EMW Status Bar and the AMW Status Bar if there are discovered
storage arrays with either condition.
The EMW Tree view has additional status icons that are shown in the
following table.

Icon Description
Setting an alert on a s storage array with a Needs
Upgrade status is not supported. In this case, the
storage array shows both a Needs Upgrade status
and an Unsupported Alerts icon in the Tree view.
The Unsupported Alerts icon indicates that the
storage array cannot be monitored.
If you installed the Event Monitor with MDSM,
and if you have set alerts, the Alert Set icon
appears next to the storage array status in the
Tree view for which the alerts have been set.
You can set alerts at any of the nodes in the Tree
view. Setting an alert at a parent node level, such
as at a host level, sets alert fir any child nodes. If
you set an alert at a parent node level and any of
the in-band storage array child nodes have a
Needs Upgrade status, the Alert Disables status
icon appears next to the parent node in the tree
view.
