8.1 Creating a New Storage Configuration You can use the MegaRAID Storage Manager to create new storage configurations on systems with ThinkServer SAS controllers. You can create the following types of configurations: • Simple configuration specifies a limited number of settings and has the system select drives for you. This option is the easiest way to create a virtual drive. • Advanced configuration lets you choose additional settings and customize virtual drive creation. This option provides greater flexibility when creating virtual drives for your specific requirements. The following subsections describe the virtual drive parameters and explain how to create simple and advanced storage configurations: • Section 8.1.1, "Selecting Virtual Drive Settings" • Section 8.1.2, "Creating a Virtual Drive Using Simple Configuration" • Section 8.1.3, "Creating a Virtual Drive Using Advanced Configuration" 8.1.1 Selecting Virtual Drive Settings This section describes the virtual drive settings that you can select when you use the advanced configuration procedure to create virtual drives. You should change these parameters only if you have a specific reason for doing so. It is usually best to leave them at their default settings. • Initialization state: Initialization prepares the storage medium for use. Specify the initialization status: ◊ No Initialization: (the default) The new configuration is not initialized and the existing data on the drives is not overwritten. ◊ Fast Initialization: The firmware quickly writes zeroes to the first and last 8-Mbyte regions of the new virtual drive and then completes the initialization in the background. This allows you to start writing data to the virtual drive immediately. 8-2 Configuration
