Choices available after opening ACU
Open ACU as described in "Getting started (on page 5)," and select a controller.

At this point, you can continue operating in Standard mode, or you can select a wizard from the lower right-hand panel. If the controller that you selected is an MSA1000, another link in this panel leads to a screen that enables you to configure switches.

Modifying a configuration using Standard Configuration mode

1.Click an item in the Configuration View panel. The right side of the screen displays a list of the tasks that are available for that item.

The tasks listed for the item are a subset of the total number of tasks that are possible for the selected item. Which of the possible tasks are listed for an item and which are omitted depends on the controller model and configuration. (For example, if the selected controller has no unassigned physical drives, Create Array is not an available task.) The table ("Possible tasks in Standard Configuration mode" on page 13) lists all the possible tasks for every type of item.

2.Click a task link. A list of all possible configuration options for that task appears on the right side of the screen, replacing the task list.

3.Set the configuration options the way that you want them to be.

4.Click OK.
