HP Microsoft Windows Server 2003 for Itanium-based Systems Opening ACU in Local Application mode

Page 7

NOTE: Some advanced tasks are not available in all operating modes. For further information, refer to "Tasks possible in each operating mode ("Choosing an operating mode" on page 7)."

2.If you opened ACU in GUI mode:

a.Select the controller that you want to configure.

b.Select the configuration mode that you want to use ("GUI operating modes" on page 10).

3.Configure the controller.

• If you are using scripting ("Scripting in ACU" on page 31) or the CLI ("Using the Command Line Interface" on page 43), refer to the appropriate chapter for further details.

• If you are using a GUI method to configure a new controller, refer to "Configuring a New Controller (on page 13)" for further details.

• If you are using a GUI method to modify an existing configuration, refer to "Modifying an Existing Configuration (on page 19)" for further details.

4.If using a GUI, save the configuration changes.

5.Select another controller to configure, or exit ACU.

6.To make newly created logical drives available for data storage, use the operating system disk management tools to create partitions and format the drives.

Choosing an operating mode

Some advanced tasks can be performed only when using a particular operating mode (GUI, CLI, or scripting).

NOTE: A + in the appropriate column indicates that the feature or procedure is supported, while -- indicates that the feature or procedure is not supported.
