  Enclosure and Backplane Properties

  Enclosure Tasks

Use this window to view information about the enclosure or backplane and execute enclosure tasks.

Enclosure and Backplane Properties

The enclosure or backplane properties can vary depending on the model of the controller. Enclosure or backplane properties may include:

Property

Definition

These icons represent the severity or health of the storage component. See "Storage Component Severity" for more information.

Name

This property displays the name of the enclosure or backplane.

State

This property displays the current status of the enclosure or backplane. Possible values are:

Ready — The enclosure or backplane is functioning normally.

Degraded — The enclosure has suffered a failure and is operating in a degraded state. The Degraded state does not apply to backplanes.

Failed — The enclosure or backplane has suffered a failure and is no longer functioning.

Connector

This property displays the number of the connector to which the enclosure or backplane is attached. This number matches the connector number on the controller hardware. Depending on the controller type, the connector can be either a SCSI channel or a SAS port.

Enclosure ID

This property displays the enclosure ID assigned to the enclosure by Storage Management. Storage Management numbers the enclosures attached to the controller starting with zero. This number is the same as the enclosure ID number reported by the "omreport Command".

Target ID

This property displays the SCSI ID of the backplane (internal to the server) or the enclosure to which the controller connector is attached. The value is usually 6.

Configuration

This property displays the mode in which the enclosure is operating. Possible values are:

Joined — Indicates that the enclosure is operating in joined-bus mode.

Split — Indicates that the enclosure is operating in split-bus mode.

Unified — Indicates that enclosure is operating in unified mode.

Clustered — Indicates that the enclosure is operating in cluster mode. Clustered mode is only available on cluster-enabled RAID controllers. See "Cluster-enabled RAID Controllers" for more information.

For more information on joined, split, and cluster modes, see the enclosure hardware documentation. For information on how to cable the enclosure to accommodate these different modes, see the enclosure hardware documentation.

When toggling the bus configuration switch on a PowerVault™ 220S or PowerVault 221S enclosure, the enclosure should be powered off. See "Changing the Mode on PowerVault 220S and PowerVault 221S Enclosures" for more information.

Older PowerVault 200S enclosures with a version 1.8 kernel that only have one EMM may display Split Bus mode and not Joined Bus mode. Joined Bus or Clustered when applicable are the only possible modes in these circumstances.

Firmware Version

This property displays the version of the enclosure firmware.

Service Tag

This property displays the enclosure's service tag number. This number is required when talking to Dell™ support. You can use this number to identify a specific enclosure in your environment by matching this number with the number on the service tag affixed to the enclosure. For example, if you have multiple enclosures and one of them experiences a failure, you can use the service tag number to identify which enclosure has failed.

Asset Tag

This property displays the asset tag information for the enclosure. You can change this property using the "Set Asset Data" task.

Asset Name

This property displays the name assigned to the enclosure. You can change this property using the "Set Asset Data" task.

Backplane Part Number

This property displays the part number of the enclosure's backplane.

Split Bus Part Number

This property displays the part number of the enclosure's split bus module. A split bus is indicated by a single triangle symbol on the back of the enclosure.

Enclosure Part Number

This property displays the part number of the enclosure.

Enclosure Alarm

This property displays whether the enclosure's alarm is enabled or disabled.

Enclosure Tasks

Do the following to execute a drop-down menu enclosure task:

  1. Expand the Storage tree object to display the controller objects.

  2. Expand a controller object.

  3. Expand a Connector object.

  4. Select the enclosure object.

  5. Select the Information/Configuration subtab.

  6. Select a task from the Available Tasks drop-down menu.

  7. Click Execute.

Drop-down Menu Enclosure Tasks:

Enable Alarm (Enclosure)

Does my enclosure support this feature? See "Enclosure and Backplane Features."

Use the Enable Alarm task to enable the enclosure alarm. When enabled, the audible alarm sounds whenever the fault LED lights. This may occur to signal events such as:

Disable Alarm (Enclosure)

Does my enclosure support this feature? See "Enclosure and Backplane Features."

Use the Disable Alarm task to disable the enclosure alarm. When disabled, the alarm does not sound when the enclosure exceeds a warning threshold for temperature or experiences other error conditions such as a failed fan, power supply, or controller. If the alarm is already sounding, you can turn it off with this task.

Set Asset Data

Does my enclosure support this feature? See "Enclosure and Backplane Features."

Use the Set Asset Data task to specify the enclosure's asset tag and asset name. See "Set Asset Data" for more information.

Blink

Does my enclosure support this feature? See "Enclosure and Backplane Features."

Use the Blink task to blink the light-emitting diodes (LEDs) on the enclosure. You may want to use this task to locate an enclosure. The LEDs on the enclosure may display different colors and blinking patterns. Refer to the enclosure hardware documentation for more information on what the blink colors and patterns indicate.

Set Temperature Probe Value

Does my enclosure support this feature? See "Enclosure and Backplane Features."

Use the Set Temperature Probe Values task to specify the Warning and Failure thresholds for the enclosure's temperature probes. See "Set Temperature Probe Values" for more information.

Identifying an Open Connector for the Enclosure

Does my controller support this feature? See "Appendix: Supported Features."

If you have not yet attached the enclosure to an open connector, you may need to identify a connector on the controller that can be used for this purpose. To identify an open connector:

  1. Expand the Storage Management tree view until the controller object is expanded. When the controller object is expanded, the tree view displays the controller's connectors. These connectors are numbered starting from zero.

  2. Identify a connector that is not attached to storage. If the connector is already attached to storage, then the Connector object can be expanded to display an enclosure or backplane and the attached physical disks. A Connector object that cannot be expanded in the tree view is an open connector not currently attached to storage. Storage Management displays a number for each connector. These numbers correspond to the connector numbers on the controller hardware. You can use these numbers to identify which open connector displayed in the tree view is the open connector on the controller hardware.

Checking the Enclosure's Temperature

Does my controller support this feature? See "Appendix: Supported Features."

To check the enclosure's temperature:

  1. Expand the tree view until the Temperatures object is displayed.

  2. Select the Temperatures object. The temperature reported by the temperature probe is displayed in Celsius in the Reading column in the right pane.

For information related to the enclosure's temperature, see the following:

Verifying the Enclosure's EMM Firmware Version

Does my controller support this feature? See "Appendix: Supported Features."

The firmware for the Enclosure Management Modules (EMMs) must be at the same level. To verify the EMM firmware version:

  1. Expand the tree view until the EMMs object is displayed.

  2. Select the EMMs object. The firmware version for each EMM is displayed in the Firmware Version column in the right pane.

For information related to the enclosure's EMMs, see "Enclosure Management Modules (EMMs)".

Enclosure Components

For information on attached components, see the following topics:
