Configuration Procedures
Creating a New Array
If you are configuring a new array, the configuration wizard leads you through
the process. If you want to bypass the wizard, use the following procedures to
create your array.
Creating a New Array—Procedure
Creating a new array involves the following general steps:
1. Choosing a controller for the array.
2. Grouping physical drives of the same size into an array.
3. Subdividing the array into one or more logical drives.
The following example illustrates using the Array Configuration Utility to
carry out these steps.
Creating a New Array—Example
For this example, make the following assumptions:
❏ Four 4.3-GB drives and two 9.1-GB drives are connected to the
Smart Array 431 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 is the 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.
Step 1: Choosing a controller for the array
1. In the Array Configuration Utility Main Configuration Screen, select the
Controller Select box. You can also select Controller/Select...from the
main menu.
2. Select one of the listed Smart Array 431 controllers.
