7.5Creating a Logical Volume

A logical volume consists of one or several logical drives. Choose “View and Edit logical volumes” in the main menu. The current logical volume configuration and status will be displayed on the screen. Choose a logical volume number (0-7) that has not yet been defined, then press [ENTER] to proceed. A prompt “Create Logical Volume?” will appear. Select “Yes”

and press [ENTER].

Select one or more logical drive(s) available on the list. The same as creating a logical drive, the logical drive(s) can be tagged for inclusion by positioning the cursor bar on the desired drive and then press [ENTER] to select. An asterisk (*) mark will appear on the selected drive. Press [ENTER] again will deselect a logical drive.

Use arrow keys to select a sub-menu and make change to the initialization mode, write policy, or the managing controller.
