Monitoring Managed Storage Array Status

When the is opened, the storage management software establishes communication with each and determines the current .

The status icons displayed in the Enterprise Management Window represent a summary status for each storage array. If a storage array has a or status, you must select the storage array and launch its management window to determine the condition that is causing this status. More detailed status icons are shown in the Management Window for the various components that comprise the storage array. Also, the Recovery Guru option provides a detailed explanation of the conditions and the appropriate steps to remedy any Needs Attention status.

While storage arrays are being contacted, the following conditions occur:

• The icon is shown in the Tree view (left pane) and Table view (right pane) until the current status of each individual managed storage array is known. See the "Status Icons in the Tree View" and "Status Icons in the Table view" topics that follow.
• The overall health status area shows the Contacting Storage Array icon, and the tooltip displays "Contacting storage arrays." See the "Status Icons in the Overall Health Status Area" topic that follows.
• As each storage array is contacted, its current status is obtained and shown in the Tree view and Table view. The applicable statuses are Optimal, Needs Attention, Fixing, or . See the "Status Icons in the Tree View" and "Status Icons in the Table view" topics that follow.

After all of the storage arrays have been contacted, the following conditions occur:

• The icon and tooltip of the overall health status area reflect the true overall health status of the storage arrays. See the "Status Icons in the Overall Health Status Area" topic that follows.
• The storage management software continues to listen for status change events. These status change events are used to update:
  • The managed storage array icons in the Enterprise Management Window
  • The more detailed component status icons in the Management Window

Important: The storage management software checks every network link to each managed storage array every five minutes for an Unresponsive status change. If a network link goes down or comes back up right after it is checked, it could be up to five minutes before the corresponding status icon is updated to reflect a change to or from Unresponsive. All other status change events are updated more quickly.

Status Icons in the Tree View

The Tree view displays seven possible types of storage array status icons.

Status	Icon	Indicates...
		Every component in the managed storage array is in the desired working condition.
		There is a problem with the managed storage array that requires your intervention to correct it.
		A Needs Attention condition has been corrected and the managed storage array is currently transitioning to an Optimal state.
		The cannot communicate with the storage array or one RAID controller module or both RAID controller modules in the storage array.
		You have started the Enterprise Management Window and the storage management software is establishing contact with the storage array.
(Firmware)		The storage array is running a level of firmware that is no longer supported by the storage management software.
Needs Upgrade Status (Software)		The storage management software you are attempting to use is incompatible with the firmware on the RAID controller modules in the storage array.

Supplemental Icons in the Tree View

There are two supplemental icons that display in the Tree view and show additional information about the storage array.

• After upgrading to this version of software, subsequent firmware and NVSRAM upgrades to certain RAID controller modules can be staged (downloaded but not activated until a user-selectable time). If the storage array has staged firmware, NVSRAM, or both, the Pending Firmware icon appears next to the storage array status icon in the Tree view.
• If you installed the with the storage management software and if you have set alerts, the Alert Set icon appears next to the storage array status in the Tree view for which alerts have been set.
  • Setting an alert on a storage array with a Needs Upgrade status is unsupported. In this case, the storage array displays both a Needs Upgrade status and an Unsupported Alerts icon in the Tree view, as shown in this example . The Unsupported Alerts icon indicates that the storage array cannot be monitored.
  • You can set alerts at any of the nodes in the Tree view. Setting an alert at a parent node level (for example, at a level) sets alerts for any child nodes. When an alert is set at a parent node level and any of the storage array child nodes have a Needs Ungrade status, then this status icon appears next to the parent node in the Tree view.

Status Icons in the Table View

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 the Enterprise Management software, an icon representing its hardware status (Optimal, Needs Attention, or Fixing) is displayed. If, however, all of the network management connections from your storage management station to the storage array (as shown in the Tree view) are Unresponsive, the storage array status is represented with an Unresponsive icon.

Status Icons in the Overall Health Status Area

The Enterprise Management Window provides an overall health status area in its lower-left corner that displays a consolidated health status for all of the known storage arrays.

There are six possible overall health status conditions:

Optimal		All discovered storage arrays have an Optimal or a Fixing status.
Needs Attention		One or more discovered storage arrays has a Needs Attention status.
Unresponsive		One or more discovered storage arrays has an Unresponsive status.
Contacting Storage Array		One or more discovered storage arrays are still being contacted. This is a temporary status; when every storage array has been contacted, this icon is replaced with the true overall health status.
Needs Upgrade		One or more discovered storage arrays is no longer supported and either the firmware or software requires an upgrade.

• Hold your mouse over the Overall Health Status icon to display a tooltip with a brief description of the status.
• The Needs Attention and Unresponsive overall health status icons both display in this area if there are discovered storage arrays in both conditions.
