HP Array Configuration Utility
About ACU
ACU is the main tool for configuring arrays on HP Smart Array controllers. It exists in three interface formats:
the ACU GUI, the ACU CLI, and ACU Scripting. All formats provide support for standard configuration tasks
(on page 6). ACU also provides support for advanced configuration tasks (on page 6). Some of the
advanced tasks are available in only one format.
The diagnostic features in ACU are also available in the standalone software HP Array Diagnostics and
SmartSSD Wear Gauge Utility (on page 96).
Starting with ACU version 9.0 and ProLiant Gen8 servers and server blades, ACU is accessible both offline
and online:
• Accessing ACU in the offline environment (on page 22)
Using one of multiple methods, you can run ACU before launching the host operating system. In offline
mode, users can configure or maintain detected and supported ProLiant devices, such as optional Smart
Array controllers, integrated Smart Array controllers, and RAID Array controllers. Some ACU CLI
features are only available in the offline environment, such as setting the boot controller and boot
volume.
• Accessing ACU in the online environment (on page 27)
This method requires an administrator to download the ACU executables and install them. You can run
ACU online after launching the host operating system.
Accessing ACU in the offline environment
To access and launch the ACU GUI in an offline environment, use one of the following methods:
• Launching ACU with HP Intelligent Provisioning (Gen8 or later) (on page 22)
• Launching ACU during POST (Gen8 or later) (on page 23)
• Launching ACU from the SmartStart CD (G7 or earlier) (on page 23)
• Launching ACU from an ISO image (all generations) (on page 23)
To access the ACU CLI or ACU Scripting in an offline environment, you must launch ACU from an ISO
image.
When offline ACU launches, an Execution Mode screen does not appear, because ACU does not support
Remote Service Mode in an offline environment. For this functionality, use ACU in an online environment
("Accessing ACU in the online environment" on page 27).
Launching ACU with HP Intelligent Provisioning (Gen8 or later)
1. Boot the server.
2. Press F10 to launch HP Intelligent Provisioning.
