Array Configuration Utility (ACU)

Figure 50: Choosing a RAID level
3. Select a RAID level and click Next.
If you have chosen a fault-tolerant RAID method, and an unassigned physical
drive of the appropriate capacity is available, ACU asks if you want to assign
a spare drive. Make your choice and click Next.
4. If ACU created more than one logical drive, you can now assign
fault-tolerance levels and spare drives to the remaining logical drives, one
logical drive at a time.
5. When you have assigned fault-tolerance levels and spare drives to all logical
drives, the screen displays the chosen configuration and asks you to confirm
that it is acceptable.
■ If you discard the suggested configuration, you are returned to the
configuration mode selection screen so that you can configure the new
array manually.
■ If you accept the suggested configuration, a screen is displayed
confirming that ACU has saved the new configuration. At this point, you
can configure another controller or you can exit ACU.
Choose the appropriate radio button.
6. Click Finish.
