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 or backplane has suffered a failure of a component and is operating in a degraded state.

    • Failed — The enclosure or backplane has suffered a failure of one or more components and is no longer functioning. Storage Management may also be unable to communicate with the enclosure or using SES commands. The Failed state is displayed when the enclosure does not respond to a status query from Storage Management for any reason. For example, disconnecting the SCSI cable would cause this state to be displayed.

Channel

This property displays the number of the channel to which the enclosure or backplane is attached. This number matches the channel number on the controller hardware.

Target ID

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

Configuration

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

  • Joined Bus — Indicates that the enclosure is operating in joined-bus mode. A joined bus is indicated by a symbol depicting two unattached triangles on the back of the enclosure.

  • Split Bus — Indicates that the enclosure is operating in split-bus mode. A split bus is indicated by a single triangle symbol on the back of the enclosure.

  • 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.

Note: When toggling the bus configuration switch on a PV220S or PV221S enclosure, the enclosure should be powered on. See Changing the Mode on PV220S and PV221S Enclosures for more information.

Kernel Version

This property displays the version of the non-upgradable 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.

Application Version

This property displays the version of the upgradable firmware.

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.

SCSI Rate

This property displays the SCSI speed.

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 channel 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)

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)

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

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

Set Temperature Probe Value

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 Channel for the Enclosure

This section applies to PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, PERC 2, 2/Si, 3/Si, 3/Di, Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, LSI 1020 and LSI 1030 controllers

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

  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 channels. These channels are numbered starting from zero.

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

Checking the Enclosure's Temperature

This section applies to PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, PERC 2, 2/Si, 3/Si, 3/Di, Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, LSI 1020, and LSI 1030 controllers

To check the enclosure's temperature:

  1. Expand the tree view until the Temperature Probes object is displayed.

  2. Select the Temperature Probes 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

This section applies to PERC 2/SC, 2/DC, 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, PERC 2, 2/Si, 3/Si, 3/Di, Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, LSI 1020, and LSI 1030 controllers

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).
