3.5.3 Using the Logical ViewLogical View is where you perform management on the logical drives and logical volumes of the disk array system. Logical drives (LDs) are combinations of physical drives, which are used to create logical volumes (LVs). These volumes (or their partitions) can then be mapped to various host LUNs.

A sub-function of the RAID View window, Logical View allows you to create, expand, and delete existing LDs and LVs. It uses unique colors to distinguish between logical drives. When a physical drive within a logical drive fails, the system notifies you by darkening the color of the affected logical drive. The logical drive will remain in this state until either a spare is detected and an automatic rebuild is started, or the drive is replaced and a rebuild is manually initiated.
After a rebuild is complete, the logical drive will display its normal color, signifying an on-line condition.
To display the Logical View, you can either click on the Logical View button in the RAID View Introduction or select the Logical View icon in the navigation panel of the RAID View window. A window similar to the one above will appear.
Note that the symbols in the Logical View initial content panel are not interactive. To select a Logical Drive or Logical Volume, click on the appropriate icon in the navigation panel.

If you need information about a particular logical drive, just let the mouse pointer hover over its corresponding icon. A readout similar to the following will appear:
This table displays the controller assignment, ID number, RAID level, total capacity, and current status of the logical drive.
For more information on how to create, delete, and rebuild logical drives and logical volumes, see Chapter 4, Array Management.
