Enclosures And Backplanes

Physical disks can be contained in an enclosure or attached to the backplane of a system. An enclosure is

attached to the system externally while the backplane and its physical disks are internal.

Backplanes

You can view the Backplane object by expanding the controller and connector object in the Storage

Management tree view. Storage Management displays the status of the backplane and the attached

physical disks. Backplane is similar to an enclosure. In a Backplane, the controller connector and physical

disks are attached to the enclosure, but it does not have the management features (temperature probes,

alarms, and so on) associated with external enclosures.

Enclosures

Storage Management enables management of various enclosures and their components. In addition to

managing the physical disks contained in the enclosure, you can monitor the status of the fans, power

supply, and temperature probes in an enclosure. You can view these components by expanding the

controller, connector, and enclosure objects in the Storage Management tree view.

Storage management allows hot plugging of enclosures. Hot plugging is defined as the adding of a

component to a system while the operating system is still running.

NOTE: This feature requires that the physical devices connected to the controller have the latest

firmware. For the latest supported firmware, contact your service provider.

After you hot plug or hot reconfigure an enclosure, refresh the left tree to display the change in status

and configuration; a system reboot is not required.

NOTE: Storage Management does not allow hot removal of enclosures. Reboot the system to effect

this change in Storage Management.

Storage Management notifies you of enclosure status changes through alerts that are displayed in the

Alert Log.

The following sections provide more information on the enclosure components and management

features provided by Storage Management:

• SMART Thermal Shutdown

• Enclosure Fans

• Enclosure Power Supplies
