Monitoring Storage Subsystem Status

When the Enterprise Management Window is opened, the storage management software establishes communication with each storage subsystem in the management domain and determines the current storage subsystem status.

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

While storage subsystems in the management domain are being contacted:

After all of the storage subsystems have been contacted:

Important: The storage subsystem management software checks every network link to each storage subsystem controller every 5 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 5 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 Device Tree View

The Device Tree View displays five possible types of storage subsystem status icons.

In the example at left, all five status icons are represented in the Device Tree.

Status

Indicates...

Optimal Status

Every component in the storage subsystem is in the desired working condition.

Needs Attention Status

There is a problem on the storage subsystem that requires your intervention to correct it.

Fixing Status

A Needs Attention condition has been corrected and the storage subsystem is currently transitioning to an Optimal state.

Unresponsive Status

The storage management station cannot communicate with the only controller or both controllers in the storage subsystem.

Contacting Device Status

You have started the Enterprise Management Window and the management software is establishing contact with the storage subsystem.

Status Icons in the Device Table View

In the Device Table, every storage subsystem is listed once, regardless of the number of attachments it has in the Device Tree. After the storage subsystem 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 subsystem (as shown in the Device Tree) are Unresponsive, the storage subsystem 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 hand corner that displays a consolidated health status for all of the known storage subsystems in the management domain.

There are four possible Overall Health Status conditions:

Optimal

All discovered storage subsystems have an Optimal or a Fixing status

Needs Attention

One or more discovered storage subsystems has a Needs Attention status

Unresponsive

One or more discovered storage subsystems has an Unresponsive status

Contacting Device

One or more discovered storage subsystems in the management domain are still being contacted. This is a temporary status; when every storage subsystem has been contacted, this icon is replaced with the true overall health status.
