Typical Manual Configuration Procedures in ACU

When you launch ACU to configure a new array, a configuration wizard opens to
allow rapid, automatic array configuration. However, you can bypass the wizard and
manually:
•
Create a new array
•
Expand the capacity of an array
•
Extend the capacity of a logical drive
•
Migrate to a different RAID level or stripe size
Creating a New Array
There are three stages in the procedure for manually creating a new array:
1. Configure the controller settings.
2. Assign physical drives of the same size to an array.
3. Create one or more logical drives on the array.
For this example, assume that you have four 4.3-GB drives and two 9.1-GB drives
connected to your controller. You want to make two arrays:
•
Array A: three 4.3-GB drives with the fourth 4.3-GB drive used as a spare. This
array is to be configured with RAID 5 fault tolerance.
•
Array B: two 9.1-GB drives in a RAID 1 fault-tolerance configuration.
Configuring the Controller Settings
1. On the ACU Main Configuration screen, select the controller to be used from
the drop-down list in the Controller Selection box. (Alternatively, click
Controller on the menu bar, and then click Select.)
2. Click Controller Settings.
The Controller Settings screen is displayed (Figure 7-9).
3. Select the rebuild priority, expand priority, and accelerator ratio.
4. Click Done to return to the ACU Main Configuration screen.
