Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide

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		Each component in the managed storage array is in the desired working condition.
Needs Attention		There is a problem with the managed storage array that requires your intervention to correct it.
Unresponsive		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		A Needs Attention status has been corrected, and the managed storage array is transitioning to an Optimal state.
Unsupported		The node is not supported by this version of MD Storage Manager.
Software Unsupported		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.

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		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		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		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		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		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		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:
