Running the Array Configuration Utility
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
■ Perform online stripe size migration
■ Perform online RAID level migration
Use the procedures in the following sections to configure your array manually.
There are three general steps for creating a new array:
1. Choose a controller for the array.
2. Group physical drives of the same size into an array.
3. Create logical drives. (Divide the array into one or more logical drives.)
For this example, use the following assumptions:
■ Four 4.3-GB drives and two 9.1-GB drives are connected to the
RA4000.
■ 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 has 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.
1. In the Array Configuration Utility Main Configuration Screen, select the
Controller Selection box. You can also select Controller/Select from the
menu bar.
