Configuration Procedures
If you are configuring a new array, the configuration wizard leads you through
the process. You can, however, bypass the wizard and manually:
■ Create a new array
■ Expand the capacity of an array
■ Extend the capacity of a logical drive
■ Change online stripe-size migration
■ Change online RAID level migration
Use the procedures in the following sections to configure your array manually.
Create a New Array
Procedure—Creating a New Array
There are three general steps for creating a new array:
■ Step 1: Choose the Smart Array 3200 controller for the array.
■ Step 2: Group physical drives of the same size into an array.
■ Step 3: Create logical drives. (Divide the array into one or more logical
drives.)
Example—Creating a New Array
For this example, use the following assumptions:
■ Four 4.3-GB drives and two 9.1-GB drives are connected to the Smart
Array 3200 Controller.
■ There will be two arrays. Array A consists of three 4.3-GB drives with
the fourth 4.3-GB drive used as a spare. Array B consisting of two 9.1-
GB drives.
■ The fault-tolerance method for all logical drives on Array A is RAID 5,
Distributed Data Guarding. The fault-tolerance method for all logical
drives on Array B is RAID 1, Drive Mirroring.
