When you open
the Enterprise Management Window (EMW), the Dell EMC PowerVault Modular
Disk Storage Manager (MD Storage Manager) establishes communication
with each managed storage array and determines the current storage
array status. The status is represented by icons next to the
managed storage array.
The status icons shown in the Tree view in
the EMW represent a summary status for each storage array. If a storage
array has a status of Needs Attention or a status of Fixing, determine
the condition that is causing this status before attempting any management
actions. You can determine the condition causing the Needs Attention
status or the Fixing status by selecting the storage array and launching
its Array Management Window (AMW).
After the AMW opens, select
the Hardware tab to see the components in the
storage array. A component that has a problem is indicated by a status
icon.
The status icons indicate the status of the components
that comprise the storage array. Also, the Recovery Guru option provides
a detailed explanation of the conditions and the applicable steps
to remedy any Needs Attention status. For more information, see Recovery Guru.
For the status of a storage array, the icons
shown in the following table are used in the Tree view, the Table
view, and both the EMW Status Bar and the AMW Status Bar.
Table 1. Status icons
and descriptionThe following table describes the different status and its icons:Status | Icon | Description |
---|
Optimal | ![Optimal status icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-A8EDDF2F-F5FD-49D1-8063-1F17EFCBF3F1-low.jpg) | Each component in the managed storage array is in the desired
working condition. |
Needs Attention | ![Needs attention icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-ABDEFC08-DB30-479C-BF39-641922B17F8F-low.jpg) | There is a problem with the managed storage array that requires
your intervention to correct it. |
Unresponsive | ![Unresponsive icon](https://dl.dell.com/topics//mdseriesagpub/images/GUID-1124AEF0-8FFC-448A-8FB8-15E1B3DBE329-low.jpg) | The storage management station cannot communicate with the
storage array or one RAID controller module or both RAID controller
modules in the storage array. |
Fixing Status | ![Fixing status icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-FEF42A90-D378-4828-AFE5-E6B358E29405-low.jpg) | A Needs Attention status has been corrected, and the managed
storage array is transitioning to an Optimal state. |
Unsupported | ![Unsupported node icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-66FE0F56-6AE3-4630-9733-EB1E48FAD888-low.jpg) | The node is not supported by this version of MD Storage
Manager. |
Software Unsupported | ![Software unsupported icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-477BCEED-460A-41DE-B7E9-C1466908177C-low.jpg) | The storage array is running a level of software that is no
longer supported by the MD Storage Manager. |
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 MD Storage Manager,
an icon representing its hardware status is displayed. Hardware status
can be Optimal, Needs Attention, or Fixing. If, however, all 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
are displayed in the 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.
Table 2. Additional status
icons and descriptionThe following table describes additional status and its icons:Status | Icon | Description |
---|
Unsupported Alerts with a Needs Upgrade Status | ![unsupported alerts with a needs upgrade status icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-04DEC14F-85FB-4ED0-B505-FB2F41AE5956-low.jpg) | Setting an alert on a 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. |
Alert Set | ![alerts set icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-925277AC-F76D-42C0-831C-C4A445F9A25B-low.jpg) | 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
for 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 is displayed next to the parent
node in the tree view. |
Setting an Alert at the Parent Node Level | ![Setting alert at parent node icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-F9A32DC9-A51A-44E5-8098-D26D64C4BF83-low.jpg) | 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
for 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. |
Adding a Storage Array | ![Adding a storage array icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-FBAD13B1-B782-4433-84BE-BAE9A90800B2-low.jpg) | The Contacting Storage Array icon is shown in the Tree view
and Table view until the status of each managed storage array
is known. The Contacting Storage Array icon is shown in the EMW Status Bar and the AMW Status Bar, and the tooltip shows Contacting
Storage arrays. As each storage array is contacted, its status is obtained and shown in the Tree view and Table view. The
applicable statuses are the Optimal, Needs Attention, Fixing, or Unresponsive. |
Adding a Storage Array OK | ![Storage array OK icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-FCB01AFB-B56B-436B-A16B-63E985D66AF8-low.jpg) | No problems were encountered while adding the storage array. The MD Storage Manager continues to check for any status change events. |
Adding a Storage Array Error | ![Adding a storage array error icon.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-87AA8A8C-6321-47B7-8DF1-69ECCF815E4A-low.jpg) | Displayed only when an error occurs. |
In the Tree view, icons can appear in a string to convey
more information. For example, the following string means that the
storage array is optimal, an alert is set for the storage array, and
firmware is available for download:![String of icons to convey more information.](https://dl.dell.com/topics//mdseriesagpub/images/GUID-942B723D-0CAA-4594-8BCE-12F30C7BA38B-low.jpg)
NOTE: The MD Storage Manager
may take a few minutes to update a status change to Unresponsive or
from Unresponsive. A status change from or to Unresponsive depends
on the network link to the storage array. All other status change
updates faster.
