# Using the ServeRAID Manager interface > Physical and Logical device views

The Physical and Logical device views show the physical devices and logical devices connected to the controller or enclosure.

The Physical devices view (on the left) displays information about the drives, enclosures, and other devices attached to the controller. The devices are shown organized by the channel or port they are connected to and shown in numerical order. The display for each channel or port includes information on maximum speed capability, the number of the channel on the controller, and the number of devices attached to the controller.

The Logical devices view (on the right) displays information about the arrays and logical drives created using the physical devices. This information includes the number of arrays and logical drives, the RAID level of each device, and whether a logical drive is protected by a hot spare drive.

To view device information, click in the Enterprise view to expand a managed system or management station. Then, select a controller or enclosure from the tree. |
For network storage, the Physical devices view also shows the controllers in the enclosure. All other information is the same. |

Tip: You can drag the bar between the Physical devices view and Logical devices view to adjust the size of each pane.

In the Physical devices view, four indicators report status of the fan, battery, temperature, and power modules on SAF-TE (enclosure management) devices and other devices that monitor these conditions. The indicator is blue for normal, yellow for warning, and red for error; the indicator is grayed out if none of the devices on the controller monitor the condition. Example: the fan indicator changes to yellow when one fan fails; it changes to red when a second fan fails and cooling is no longer adequate.

In the Logical devices view, use the buttons to create and delete arrays and logical drives. The Create option () opens a wizard that presents the steps necessary to create a new array.

Other buttons in the Logical devices view allow you to:

- Change the way configuration information is displayed
- Collapse and expand configuration information
- Identify components of an array or logical drive

You can also create and delete hot-spare drives.
