3.4Performing a Quick Configuration

This section provides quick installation steps for users that are familiar with configuration utilities and tools. Refer to Section 3.5, “Configuring Arrays and Logical Drives,” for detailed configuration instructions. To ensure best performance, select the optimal RAID level for the logical drive you create.

Perform the following steps to configure arrays and logical drives using the

Configuration Utility (CU):

Step 1. Boot the system.

Step 2. Start the CU by pressing <Ctrl><M>.

Step 3. Select a configuration method.

Step 4. Create arrays using the available physical drives.

Step 5. Define the logical drive(s) using the space in the arrays.

Step 6. Initialize the new logical drive(s).
