Overview of array configuration tools 5
Overview of array configuration tools
Utilities available for configuring an array
To configure an array on an HP Smart Array controller, three utilities are available:
•HP Array Configuration Utility (ACU)—An advanced utility that enables you to perform many complex
configuration tasks
•Option ROM Configuration for Arrays (ORCA)—A simple utility used mainly to configure the first logical
drive in a new server before the operating system is loaded
•HP Online Array Configuration Utility for NetWare (CPQONLIN)—A customized version of ACU for
online configuration of servers that use Novell NetWare
Before you use a utility, confirm that the utility can support the required task. View a comparison of the utilities
(on page 5).
Whichever utility you use, remember the following factors when you build an array:
•All drives grouped in a logical drive must be of the same type (for example, either all SAS or all SATA
and either all hard drives or all solid state drives).
•For the most efficient use of drive space, all drives within an array should have approximately the same
capacity. Each configuration utility treats every physical drive in an array as if it has the same capacity
as the smallest drive in the array. Any excess capacity of a particular drive cannot be used in the array
and is unavailable for data storage.
•The more physical drives configured in an array, the greater the probability that the array will
experience a drive failure during any given period.
•To guard against the data loss that occurs when a drive fails, configure all logical drives in an array with
a suitable fault-tolerance (RAID) method. For more information, see "Drive arrays and fault-tolerance
methods (on page 110)."

Overview of array configuration tools 6
ORCA supports only basic configuration tasks, whereas CPQONLIN and ACU provide full-range support for
standard configuration tasks (on page 6). ACU also provides support for advanced configuration tasks (on
page 6). Some of these advanced tasks are not available in all ACU interface formats (GUI, CLI, and
Scripting).

Required hardware
For a list of Smart Array controllers that support SAAP, see the SAAP product page on the HP website
(http://www.hp.com/go/SAAP).

HP Smart Array Advanced Pack 9
To support some controller features, the controller may also require a hardware configuration that includes
the following cache (array accelerator) options:
•A cache module that is 256 MiB or larger
•A compatible battery pack or capacitor pack
To obtain these options, contact an HP authorized reseller or see the HP website
(http://www.hp.com/products/smartarray).

Option ROM Configuration for Arrays 10
Option ROM Configuration for Arrays
About ORCA
ORCA is a ROM-resident array configuration utility that executes automatically during initialization of an HP
Smart Array controller. This utility is designed to enable a logical drive to be configured on a new HP server
before the operating system is installed:
•If the boot drive has not been formatted and the boot controller is connected to six or fewer physical
drives, ORCA runs as part of the auto-configuration process when the new server is first powered up.
During this auto-configuration process, ORCA uses all of the physical drives on the controller to set up
the first logical drive. The RAID level used for the logical drive depends on the number of physical drives
(one drive = RAID 0; two drives = RAID 1+0; three to six drives = RAID 5). If the drives have different
capacities, ORCA locates the smallest drive and uses the capacity of that drive to determine how much
space to use on each of the other drives.
•If the boot drive has been formatted or if there are more than six drives connected to the controller, you
are prompted to run ORCA manually.
For more information about the auto-configuration process, see the HP ROM-Based Setup Utility User Guide
on the Documentation CD that is provided with the server.
ORCA is available in two formats:
•Using the ORCA menu-driven interface
•Using the ORCA CLI
HP ProLiant 100 Series servers do not support the CLI format. For these servers, use the menu-driven
interface.
Either format provides a quick and easy method for basic logical drive configuration. Both formats have
limited support for standard configuration tasks (on page 6). However, these few tasks are adequate if your
configuration needs are simple. For example, stripe size is predetermined by the RAID level that you choose,
and the size of the logical drive is determined automatically by the size of the physical drives that you select.

NetWare
About CPQONLIN
The HP Online Array Configuration Utility for NetWare (CPQONLIN) enables you to configure an array on
a NetWare server while the server is online.
To configure an array when the server is offline, use ACU.
To install CPQONLIN, obtain the appropriate Smart Component from the HP website
(http://www.hp.com/support) or the software CD that is provided with the controller. When prompted for
product information, enter the appropriate server model name. Installation instructions are provided with the
component.
Summary of configuration procedure using
CPQONLIN
1. At the console prompt, enter cpqonlin.
2. Press the arrow keys to scroll the highlight to the Array Configuration Utility menu item, and then press
the Enter key.
The screen displays a list of the controllers in the server.
3. Scroll to the controller that you want to configure and then press the Enter key.
oIf there are no logical drives connected to the controller, an auto-configuration wizard opens and
displays the optimum configuration for the drives on the controller. You can accept the suggested
configuration, modify just the RAID level of any logical drives, or use the Custom Configuration
option to completely reconfigure the drives manually ("Operating CPQONLIN in manual
configuration mode" on page 11).
oIf there is at least one logical drive connected to the controller, CPQONLIN continues in manual
configuration mode ("Operating CPQONLIN in manual configuration mode" on page 11). Press
the arrow, Enter, and Esc keys to navigate around the screen and set up the new logical drive. To
get online help at any time, press the F1 key.
4. When you have finished configuring the array, save the changes as prompted.
5. To make new logical drives available for data storage, format them using the instructions given in the
operating system documentation.

Typical manual configuration procedures
This section describes the procedures for the following common tasks:
•Creating a new array and logical drive (on page 14)
•Adding spare drives (on page 14)
•Setting the rebuild priority or expand priority (on page 15)
•Setting the accelerator ratio (on page 15)
•Expanding an array (on page 16)
•Migrating RAID level or stripe size (on page 16)

HP Online Array Configuration Utility for NetWare 14
Creating a new array and logical drive
1. Open CPQONLIN and select the controller that you want to configure.
The Logical Configuration View panel appears.
2. Press the Enter key.
The highlight moves to the Controller Options panel.
3. Highlight the Create New Array option, and then press the Enter key.
The screen displays three panels (Create Array, Physical Drives, and New Array), and the highlight
moves to the Create Array panel.
4. Highlight the Assign Drive option, and then press the Enter key.
The highlight moves to the Physical Drives panel.
5. Highlight a drive that you want to be part of the array, and then press the Enter key.
The New Array panel displays the added drive, and the highlight returns to the Create Array panel.
6. Repeat steps 4 and 5 until you have finished building the array.
oFor the most efficient use of drive space, select physical drives of comparable capacity.
oFor optimum system performance, select physical drives that are connected to different ports on the
controller.
oIf you intend to create a RAID 5 configuration, keep the risk of logical drive failure low by assigning
no more than 14 physical drives to the array.
oDo not select any physical drives that you want to be spare drives. Spare drives are created in a
separate procedure ("Adding spare drives" on page 14).
7. Highlight the Accept Changes menu option, and then press the Enter key.
The Create New Logical Drive panel appears.
8. Select the RAID level that you want the logical drive to use, and then press the Enter key.
9. Select the stripe size that you want the logical drive to use, and then press the Enter key.
10. Enter the capacity that you want the logical drive to have, and then press the Enter key.
11. Press the Esc key to save the settings and return to the Logical Configuration View panel.
12. To make new logical drives available for data storage, format them using the instructions given in the
operating system documentation.
Adding spare drives
Assigning one or more online spare drives to an array enables you to postpone replacement of faulty drives.
However, it does not increase the fault-tolerance level of any logical drives in the array. For example, a
logical drive in a RAID 5 configuration suffers irretrievable data loss if two of its physical drives are
simultaneously in a failed state, regardless of the number of spare drives assigned to the array.
Any drive that you want to use as a spare must meet the following criteria:
•It must be an unassigned drive or a spare for another array.
•It must be of the same type as existing drives in the array (for example, SATA or SAS).
•It must have a capacity no less than that of the smallest drive in the array.
To add a spare drive to an array:

HP Online Array Configuration Utility for NetWare 15
1. In the Logical Configuration View panel, highlight the array that needs a spare, and then press the Enter
key.
2. In the Array Options menu, highlight the Assign Spare option, and then press the Enter key.
The screen displays the Valid Spares Selection(s) panel, which displays only the drives that qualify to be
spares for the selected array. If a drive that you expect to see is not listed, it might have too small a
capacity compared to the other drives in the array. Press the Tab key to toggle to the physical
configuration view and check the drive size.
3. Highlight the drive that you want to assign as a spare, and then press the Enter key.
4. (Optional) Add more spares to the array by repeating step 3.
5. When you have finished assigning spares, press the Esc key to return the highlight to the Array Options
menu.
Setting the rebuild priority or expand priority
The settings that you use for the rebuild priority and expand priority features determine how much importance
you want an array rebuild or expansion to have relative to normal I/O operations.
•At the low priority setting, the rebuild or expansion takes place only when the controller is not busy
handling normal I/O requests. This setting has minimal effect on normal I/O operations. However, an
array that is rebuilt at this setting must operate for an extended time with possibly compromised fault
tolerance during the rebuild, and if another physical drive fails during this time, you could lose data.
•At the medium priority setting, rebuild or expansion occurs for half of the time, and normal I/O requests
are handled during the rest of the time.
•At the high priority setting, the rebuild or expansion occurs at the expense of normal I/O operations.
Although system performance is affected, this setting provides better data protection because the array
is vulnerable to drive failure for a shorter time.
To modify either of these settings:
1. In the Logical Configuration View panel, highlight the controller, and then press the Enter key.
The highlight moves to the Controller Options panel.
2. Highlight the Controller Settings option, and then press the Enter key.
The Controller Settings panel appears.
3. Highlight the rebuild priority setting that you want this controller to use, and then press the Enter key.
(This setting applies only to logical drives that have been configured with RAID 1+0, RAID 5, or RAID
6 fault tolerance because only these logical drives can be rebuilt.)
4. Repeat step 3 for the expand priority setting.
5. Press the Esc key to save the settings and return to the Logical Configuration View panel.
Setting the accelerator ratio
The setting that you use for the accelerator ratio feature determines how much of the cache memory is
allocated to read-ahead cache and how much to posted-write cache. Different applications have different
optimum settings. This setting applies only if the controller uses a battery-backed cache.
To modify the accelerator ratio:
1. In the Logical Configuration View panel, highlight the controller, and then press the Enter key.
The highlight moves to the Controller Options panel.

HP Online Array Configuration Utility for NetWare 16
2. Highlight the Controller Settings option, and then press the Enter key.
The Controller Settings panel appears.
3. Highlight the accelerator ratio setting that you want this controller to use, and then press the Enter key.
4. Press the Esc key to save the settings and return to the Logical Configuration View panel.
Expanding an array
You can increase the storage space on an array by adding physical drives. Any drive that you want to add
must meet the following criteria:
•It must be an unassigned drive.
•It must be of the same type as existing drives in the array (for example, SATA or SAS).
•It must have a capacity no less than that of the smallest drive in the array.
When you want to expand an array, allow about 15 minutes per gigabyte for the expansion to be
completed. During this time, the controller cannot perform any other expansion or migration. Performance
might be degraded slightly during the expansion, depending on the Expand Priority setting ("Setting the
rebuild priority or expand priority" on page 15). To minimize any effect on normal server operations,
expand an array during periods of low server use.
To expand an array:
1. Back up all data on the array. Although array expansion is unlikely to cause data loss, observing this
precaution provides extra data security.
2. Confirm that the cache battery is connected and fully charged.
3. In the Logical Configuration View panel, highlight the array, and then press the Enter key.
4. In the Array Options menu, highlight the Expand Array option, and then press the Enter key.
The screen displays three panels (Expand Array, Physical Drives, and Expand Existing Array), and the
highlight moves to the Expand Array panel.
5. Highlight the Assign Drive option, and then press the Enter key.
The highlight moves to the Physical Drives panel.
6. Highlight a physical drive that you want to add to the array, and then press the Enter key. (For optimum
use of drive capacity, select a drive that has the same capacity as other drives in the array.)
The highlight returns to the Expand Array panel.
7. (Optional) Repeat steps 5 and 6 to add more drives.
8. Highlight the Accept Changes option, and then press the Enter key.
9. Press the Esc key to begin the array expansion and return to the Logical Configuration View panel.
To view the progress of the array expansion, press the F3 key, and then scroll to the progress bar near the
bottom of the screen.
Migrating RAID level or stripe size
When you want to migrate the RAID level or stripe size, allow about 15 minutes per gigabyte for the
migration to be completed. During this time, the controller cannot perform any other expansion or migration.
Performance might be degraded slightly during the migration, depending on the Expand Priority and Rebuild
Priority settings ("Setting the rebuild priority or expand priority" on page 15). To minimize any effect on
normal server operations, migrate during periods of low server use.

HP Online Array Configuration Utility for NetWare 17
To perform a migration:
1. Back up all data on the array. Although migration is unlikely to cause data loss, observing this
precaution provides extra data security.
2. Confirm that the cache battery is connected and fully charged.
3. In the Logical Configuration View panel, highlight the logical drive and then press the Enter key.
The highlight moves to the Logical Drive Options panel.
4. Highlight the Drive Settings option, and then press the Enter key.
The Drive Settings panel appears.
5. Modify the Fault Tolerance and Stripe Size settings on this panel to meet your needs.
6. Press the Esc key to begin the migration and return to the Logical Configuration View panel.

HP Array Configuration Utility 18
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 100).
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 18)
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 23)
This method requires an administrator to download the ACU executables and install them. You can run
ACU online after launching the host operating system.
Native support for 64-bit and 32-bit operating
systems
ACU now offers a native 64-bit ACU application for supported 64-bit operating systems, eliminating the
need for compatibility libraries. A 32-bit ACU application is also available. Users can choose to install the
application that matches the OS installed on the server product.
The 64-bit ACU application is not a direct upgrade from 32-bit ACU. On 64-bit systems running 32-bit ACU,
you must uninstall the 32-bit application, and then install the 64-bit application.
Future versions of ACU will be available as native 32-bit or native 64-bit applications, as long as 32-bit
operating systems are supported.
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 19)
•Launching ACU during POST (Gen8 or later) (on page 19)

HP Array Configuration Utility 19
•Launching ACU from the SmartStart CD (G7 or earlier) (on page 19)
•Launching ACU from an ISO image (all generations) (on page 19)
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 23).
Launching ACU with HP Intelligent Provisioning (Gen8 or later)
1. Boot the server.
2. Press F10 to launch HP Intelligent Provisioning.
3. At the main screen, select Perform Maintenance.
4. At the Maintenance screen, select Array Configuration Utility (ACU).
The system launches the ACU GUI.
Launching ACU during POST (Gen8 or later)
1. Boot the server.
During POST, the system recognizes devices.
2. When the system recognizes a Smart Array controller, press F5.
The system launches the ACU GUI.
Launching ACU from the SmartStart CD (G7 or earlier)
1. Close all applications.
2. Insert the SmartStart CD into the CD-ROM drive.
3. Restart the server.
The server boots from the CD, and then loads the SmartStart executable and drivers.
4. When prompted, select the language and agree to the license restrictions.
5. Click Maintain Server.

ACU opens, scans the local server, and detects controllers. This process can last up to 2 minutes. When
controller detection is complete, the controllers are available on the Controller/Device menu.
Launching ACU from an ISO image (all generations)
To launch ACU, you can also boot from an ISO image. To prepare the image, use one of the following
methods:
•Mounting the image on a local drive (on page 20)
•Mounting the image through iLO (on page 20)
•Burning the image to a CD or DVD (on page 20)
•Flashing the image to a USB memory key or SD card (on page 20)
