Connecting Storage Devices.........................................................................................................15
Before Beginning the Installation
Before beginning the installation procedure, visit the HP website
(http://www.hp.com/support
) to confirm that you have the latest version of each
driver and utility file needed. Compare the version numbers of the files there
with those of the same files on the software CD or DVD that is supplied in the
controller kit.
Preparing the Server
Before installing the controller in the server, back up all data. This step is
required if you are moving non-arrayed SCSI drives to a Smart Array controller,
because data is not preserved during a move between array controllers and nonarray controllers.
If the server supports hot-pluggable devices, you can install the controller board
without any further preparation ("Installing the Controller Board" on page 14
To prepare a server that does not support hot-pluggable devices:
1. Close all applications.
2. Power down the server.
).
14 HP Smart Array 6402 Controller for Integrity Servers User Guide
CAUTION: In systems that use external data storage, be sure
that the server is the first unit to be powered down and the last to be
powered back up. Taking this precaution ensures that the system does
not erroneously mark the drives as failed when the server is powered
up.
3. Power down all peripheral devices that are attached to the server.
4. Unplug the AC power cord from the outlet and then from the server.
5. Disconnect all peripheral devices from the server.
Installing the Controller Board
WARNING: To reduce the risk of personal injury or
damage to the equipment, consult the safety information and user
documentation provided with the server before attempting the
installation.
Many servers are capable of providing energy levels that are
considered hazardous and are intended to be serviced only by
qualified personnel who have been trained to deal with these
hazards. Do not remove enclosures or attempt to bypass any
interlocks that may be provided for the purpose of removing these
hazardous conditions.
1. Remove or open the access panel.
2. Select an available 3.3-V PCI or PCI-X slot.
NOTE: In Integrity servers, the ID number of the slot in which you insert
the controller determines the boot controller order. Follow the
recommendations in the server-specific documentation to obtain the
required controller order.
3. Remove the slot cover or open the hot-plug latch. Save the retaining screw if
one is present.
4. Slide the controller board along the slot alignment guide, and press the board
firmly into the slot so that the contacts on the board edge are properly seated
in the system board connector.
5. Secure the controller board in place with the hot-plug latch or retaining
screw. If there is a guide latch on the rear of the board, close the latch.
Installing the Controller Hardware 15
6. To finish installing the hardware, connect the internal and external drives
("Connecting Storage Devices" on page 15
).
Connecting Storage Devices
The controller supports Ultra2, Ultra160 (Ultra3), and Ultra320 drives.
Each peripheral that is connected to the controller must have a unique SCSI ID
value within the range of 0 to 15 (except ID 7, which is reserved for controller
use). This value determines the priority that is given to the device when it
attempts to use the SCSI bus.
The system automatically sets the SCSI IDs for hot-pluggable devices if they are
supported. For non-hot-pluggable devices, you must set the ID values manually
by using switches or jumpers on the device itself.
SCSI buses require termination on both ends to prevent signal degradation. In HP
ProLiant and Integrity servers, however, the controller, SCSI cable, and
backplane already provide this termination.
Connecting Internal Storage
1. If the storage device that you are adding is not hot-pluggable, power down
the system.
2. Install drives in the removable media bays on the server.
CAUTION: Do not use hot-pluggable drives on the same SCSI
bus as non-hot-pluggable drives.
NOTE: Drives that are to be grouped in the same array should all have
comparable capacity for efficient use of total storage capacity.
For additional information about drive installation, refer to the appropriate
section in this guide ("Replacing, Moving, or Adding Hard Drives" on page
37
) and consult the documentation that accompanied the drives.
When you have finished installing drives, continue with the next step.
− If the drives are hot-pluggable, go to step 3.
16 HP Smart Array 6402 Controller for Integrity Servers User Guide
− If the drives are not hot-pluggable, go to step 4.
3. Attach the internal point-to-point SCSI cable (provided with the server) from
the internal connector of the controller to the hot-plug drive cage.
Installation of the hot-pluggable drives is complete.
4. For each SCSI bus, manually set the SCSI ID on each drive to a unique value
in the range of 0 to 15, except 7 (which is reserved for controller use). For
detailed instructions, consult the documentation that is provided with the
drive.
5. Attach a multi-device SCSI cable from the internal connector of the
controller to the non-hot-pluggable hard drives. (The cable may have been
provided with the server.)
6. Replace the access panel, and secure it with the thumbscrews if any are
present.
CAUTION: Do not operate the server for long periods without
the access panel. Operating the server without the access panel results
in improper airflow and improper cooling that can lead to thermal
damage.
Connecting External Storage
1. On the rear of the server, connect the external cable to the VHDCI connector
on the controller, and tighten the lock screws on the cable connector.
2. Attach the other end of the cable to the storage enclosure, and tighten the
lock screws on the cable connector.

Introduction ..................................................................................................................................21
Comparing the Utilities ................................................................................................................22
Using ORCA ................................................................................................................................23
Using ACU ...................................................................................................................................25
Introduction
HP provides two utilities for manually configuring an array on a Smart Array
controller:
• ACU—A versatile, browser-based utility that provides maximum control
over configuration parameters
• ORCA—A simple ROM-based configuration utility that runs on all
operating systems
NOTE: To copy a particular array configuration to several other servers
on the same network, use the scripting capability of ACU.
Whichever utility you use, the following limitations apply:
• For the most efficient use of drive space, do not mix drives of different
capacities within the same array. The configuration utility treats all physical
drives in an array as if they have the same capacity as the smallest drive in
the array. The excess capacity of any larger drives is wasted because it is
unavailable for data storage.
• The probability that an array will experience a drive failure increases with
the number of physical drives in the array. If you configure a logical drive
with RAID 5, keep the probability of failure low by using no more than 14
physical drives in the array.
For information about default array configuration settings, refer to the HP Array
Configuration Utility User Guide. This document is available on the
Documentation CD that is provided in the controller kit.

Using ORCA
NOTE: Before you power up the server in step 1, read through the
instructions for step 2 to determine which procedure you must follow to
start ORCA. The ORCA prompt persists for only a few seconds, and if
you do not start ORCA during this time, you must restart the server to
obtain the ORCA prompt again.
1. Power up the server. POST runs, and any array controllers that are in the
system are initialized one at a time.
2. Use the appropriate procedure to start ORCA:
− If you are accessing the server remotely using Telnet or HyperTerminal
on a Microsoft
®
Windows® 2000 or Windows NT® 4.0 system, press the
Esc + 8 keys when the Smart Array banner appears on the remote
console.
− If you are configuring the boot logical drive on a cell-based system,
execute a search all command at the EFI prompt. When the ORCA
prompt appears, press the F8 key.
− On all other systems, POST halts for several seconds during each
controller initialization process while an ORCA prompt message
appears. When you see the prompt, press the F8 key.
24 HP Smart Array 6402 Controller for Integrity Servers User Guide
The ORCA main menu appears, enabling you to create, view, or delete a
logical drive.
To create a logical drive using ORCA:
1. Select Create Logical Drive.
The screen displays a list of all available (unconfigured) physical drives and
the valid RAID options for the system.
2. Use the Arrow keys, Spacebar, and Tab key to navigate around the screen
and set up the logical drive, including an online spare drive if one is required.
NOTE: You cannot use ORCA to configure one spare drive to be
shared among several arrays. Only ACU enables you to configure
shared spare drives.
While configuring the logical drive, one of the settings allows you to use
either 4 GB or 8 GB as the maximum boot drive size. Selecting 8 GB allows
a larger boot partition for operating systems such as Microsoft
Windows NT
®
4.0 that use cylinders, heads, and sectors of a physical drive to
®
determine the drive size. The larger boot drive size also lets you increase the
size of the logical drive at some later time. However, logical drive
performance is likely to decrease if the larger boot drive size is enabled.
