8.1.4 Creating a Virtual Drive Using
Simple Configuration
Simple configuration is the quickest and easiest way to create a new storage
configuration. When you select simple configuration mode, the system creates the best
configuration possible using the available drives.
NOTE: You cannot create spanned drives using the simple configuration procedure. To
create spanned drives, use the advanced configuration procedure described in
Section 8.1.5, Creating a Virtual Drive using Advanced Configuration .
Follow these steps to create a new storage configuration in simple configuration mode.
1. Perform either of the following steps:
— Right-click the controller node in the device tree in the left frame of the
MegaRAID Storage Manager window, and select Create Virtual Drive.
— Select the controller node, and select Go To>>Controller>>Create Virtual Drive
in the menu bar, as shown in Figure 205 .
