Figure 1-2: Controller installation in an already configured system

1-2 HP Smart Array 641/642 Controller User Guide

Preparing the Server

Before installing the controller in the server, back up all data. This step is mandatory 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 non-array controllers.

WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with the computer before attempting the installation.

Many computers are capable of providing energy levels that are considered hazardous, and are only intended to be serviced by qualified personnel trained in dealing 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.

Installing the Hardware

If the server supports hot-pluggable devices, go directly to the “Installing the Smart Array Controller” section.

To prepare a server that does not support hot-pluggable devices:

1. Close all applications.

2. Power down the server.

CAUTION: In systems using external data storage, be sure that the server is the first unit powered down and the last unit to be powered back up. This precaution ensures that the system will not erroneously mark the drives as failed.

3. Power down any peripheral devices that are attached to the server.

HP Smart Array 641/642 Controller User Guide 2-1

Installing the Hardware

4. Unplug the AC power cord from the outlet, and then from the server.

5. Disconnect any peripheral devices from the server.

Installing the Smart Array Controller

1. Remove or open the access panel.

2. Select an available 3.3-V PCI or PCI-X slot.

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.

6. Continue by following the instructions given in “Connecting the Cables.”

Connecting the Cables

Each peripheral that is connected to the server must have a unique SCSI ID value, falling in the range from 0 to 15 (except ID 7, which is reserved for controller use). The SCSI ID value determines the priority that is given to the device when it attempts to use the SCSI bus.

On products that support hot-pluggable devices, the SCSI IDs for such peripherals are automatically set. The IDs for non-hot-pluggable devices must be set manually by using switches or jumpers on the device itself.

SCSI buses require termination on both ends to prevent signal degradation. In all Compaq servers and storage systems, and the newer ProLiant systems, the controller, SCSI cable, and backplane already provide this termination.

Internal Cabling

1. If the device is not hot pluggable, power down the system.

2-2 HP Smart Array 641/642 Controller User Guide

Installing the Hardware

2. Install drives into the removable media bays on the server. (For additional

information about drive installation, consult the documentation that accompanied the drives, and refer to Appendix E.)

NOTE: Drives that are to be grouped in the same array should have the same capacity.

— If the drives are hot pluggable, go to step 3.

— 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 the multi-device SCSI cable from the internal connector of the controller

to the non-hot-pluggable hard drives.

The multi-device cable may have been provided with the server. If you need additional cables, order the cable option kit, Part Number 166389-B21. This cable is equipped to terminate Ultra2, Ultra160 (Ultra3), or Ultra320 (Ultra4) drives.

CAUTION: Cable assembly 148785-001 is included in option kit 166389-B21 and is required with Ultra3 and Ultra4 drives. Failure to use this cable may result in reduced performance, data loss, or both.

External Cabling (Model 642 only)

1. On the rear of the server, connect the cable to the VHDCI connector on the

controller, and then tighten the lock screws on the cable connector.

2. Attach the other end of the cable to the storage enclosure, and then tighten the

lock screws on the cable connector.

3. Replace the access panel and secure it with the thumbscrews, as required.

HP Smart Array 641/642 Controller User Guide 2-3

Installing the Hardware

CAUTION: Do not operate the server with the access panel removed for extended periods of time. This precaution protects thermally sensitive components by ensuring the proper airflow through the server, and minimizes personal contact with hazardous energy levels.

Updating the Firmware

You can update the firmware using the Smart Components, which are downloadable from the HP website. Detailed instructions for using the Smart Components are given on the Web page that contains the components.

NOTE: Some newer ProLiant servers automatically update the system and controller firmware when they are powered up for the first time. To determine whether this situation is true for a particular server, refer to the server-specific setup and installation guide.

Alternatively, if the server uses Microsoft Windows 2000 or Microsoft Windows NT as the operating system, you can use one of the CDs that are supplied with the controller to accomplish the firmware updates. Before using either CD, check the Smart Components on the HP website to see whether newer versions of the firmware upgrade files are available.

1. Insert the CD into the CD-ROM drive of the server.

— If the server was configured using the ROM-Based Setup Utility (RBSU),

use the SmartStart CD (version 6.0 or later).

— If the server did not use RBSU, use the Support Software CD.

If you want to run the firmware updates while offline, restart the server now, and then wait for controller initialization to finish.

The ProLiant Storage Software license agreement page is displayed.

2. Click Agree.

The main ProLiant Storage Software screen is displayed.

3. Click ROM Update Utility.

4. Click the Updates tab.

HP Smart Array 641/642 Controller User Guide 3-1

Updating the Firmware

5. Select Express or Custom mode, and follow the on-screen prompts and instructions to update the firmware on the system and the controller.

If the server does not use RBSU, you now need to use the System Configuration Utility (SCU) to update the system partition.

1. Locate the page on the HP website that contains SCU and follow the on-screen instructions to create four SCU diskettes.

2. Insert SCU diskette #1 into the server diskette drive.

3. Restart the system.

4. Select System Configuration Utility from the menu or list of icons that is

displayed.

5. Follow the on-screen instructions to update or create and populate a system partition.

6. Exit from SCU. If the server does not reboot or a CD error message is displayed, press the Ctrl+Alt+Del keys to reboot the server manually.

3-2 HP Smart Array 641/642 Controller User Guide

Setting the Controller Order

After installing the controller hardware and updating the firmware:

• Configure the server by using either RBSU or SCU. A brief description of the

procedure is given in this chapter; the server user guide provides more details.

IMPORTANT: When using SCU to reconfigure a system that uses a Smart Array 641 or 642 Controller as the boot controller, use ORCA immediately afterwards to check that the controller order is unchanged. Reset the controller order if necessary.

NOTE: Some newer ProLiant servers configure themselves automatically when they are powered up for the first time. To determine whether this situation is true for a particular server, refer to the server-specific setup and installation guide.

• Set the boot controller by using RBSU or the Option ROM Configuration for

Arrays (ORCA) utility, as described in this chapter.

• Create at least one logical drive, as described in Chapter 5.

NOTE: Some newer ProLiant servers automatically create a logical drive and configure a RAID level when they are powered up for the first time. For this sequence of events to occur, the server must have fewer than seven internal hard drives, and the boot drive must not have been written to. To determine whether this situation applies to a particular server, refer to the server-specific setup and installation guide.

Using RBSU

RBSU is a system configuration utility that is embedded in the system ROM, and is customized for the server that it is installed on.

HP Smart Array 641/642 Controller User Guide 4-1

Setting the Controller Order

CAUTION: Not all servers support RBSU. Do not flash an RBSU-ROM image onto a server that is already configured with SCU unless the update instructions specifically state that upgrading from SCU to RBSU is supported. If the upgrade is not supported, the consequences of upgrading are unpredictable and you may lose data.

To use RBSU:

1. Power up the server.

2. Press the F9 key when prompted during system startup.

The main RBSU screen is displayed.

3. Configure the system. (For detailed instructions, refer to the ROM-Based Setup Utility User Guide.)

4. Select Boot Controller Order on the main RBSU screen and follow the on-screen prompts to set the boot controller.

5. When you have finished using the utility, press the Esc key, and then press the F10 key to confirm that you want to exit RBSU.

Using ORCA

Part of the startup sequence of a server is the Power-On Self-Test (POST). If the array controller in the server supports ORCA, POST temporarily halts and an ORCA prompt message is displayed for about five seconds. (If ORCA is not supported, the prompt message is not displayed and the system continues with the startup sequence.)

1. Power up the server and let the system startup sequence begin.

2. While the prompt message is displayed, press the F8 key to start ORCA.

3. On the Main Menu screen, select Select as Boot Controller and follow the

prompts to set the boot controller for the system.

If you want to use ORCA to create logical drives, you do not need to exit the utility yet. Continue using ORCA as described in Chapter 5.

4-2 HP Smart Array 641/642 Controller User Guide

Configuring an Array

HP provides three utilities for manually configuring an array:

• Array Configuration Utility (ACU)—A versatile, browser-based utility that

provides maximum control over configuration parameters

• Option ROM Configuration for Arrays (ORCA)—A simple ROM-based

configuration utility that runs on all operating systems

• NetWare Online Array Configuration Utility (CPQONLIN)—A menu-driven

utility for NetWare

NOTE: If you want to copy a particular array configuration to several other servers on the same network, use the Array Configuration Replicator (ACR) or the scripting capability of ACU. ACR is provided in the SmartStart Scripting Toolkit, available at www.hp.com/servers/sstoolkit.

For background information about drive arrays and fault-tolerance (RAID) methods, refer to Appendix D.

The following limitations apply to all configuration methods:

• For the most efficient use of drive space, do not mix drives of different capacity

within the same array. Each configuration utility treats all physical drives in an array as if they have the same capacity as the smallest drive in the array. Excess capacity of larger drives is wasted because it is unavailable for data storage.

• The probability that an array will experience a hard drive failure increases with

the number of hard drives in the array (for more detailed information, refer to Appendix F). If you configure an array with RAID 5, keep the probability of failure acceptably low by using no more than 14 drives.

5-2 HP Smart Array 641/642 Controller User Guide

Using ACU

For detailed information about using ACU, refer to the HP Array Configuration Utility User Guide.

Using ORCA

When a computer system is powered up, part of the startup sequence is the Power-On Self-Test (POST). Any array controllers that are in the system are initialized while POST is running. If the array controller supports ORCA, POST temporarily halts and an ORCA prompt message is displayed for about five seconds. (If ORCA is not supported, the prompt message is not displayed and the system continues with the startup sequence.)

While the prompt is displayed, press the F8 key to start ORCA. The ORCA main menu is displayed, allowing you to select the boot controller for the system, or to create, view, or delete a logical drive.

Configuring an Array

Figure 5-1: ORCA main menu screen

NOTE: The maximum allowable boot drive size with ORCA is 4 GB.

To create a logical drive:

1. Select Create Logical Drive.

The screen displays a list of all available (unconfigured) physical drives and the valid RAID options for the system.

HP Smart Array 641/642 Controller User Guide 5-3

Configuring an Array

NOTE: You can create only one logical drive at a time.

2. Use the arrow keys, space bar, and tab key to navigate around the screen and set up the logical drive, including a spare drive if required.

NOTE: ORCA allows only one array to use a given online spare.

3. Press the Enter key to accept the settings.

4. Press the F8 key to confirm the settings and save the new configuration.

After several seconds, the Configuration Saved screen is displayed.

5. Press the Enter key to continue.

You can now create another logical drive by repeating the previous steps.

NOTE: Raw logical drives are invisible to the operating system. To make the new logical drives available for data storage, format the logical drive using the instructions given in the operating system documentation.

Using CPQONLIN

The NetWare Online Array Configuration utility (CPQONLIN) lets you configure drive arrays without shutting down the server. It also indicates when a drive attached to the array controller has failed, is undergoing expansion, or is waiting (queued) for expansion or rebuild.

IMPORTANT: The maximum logical drive size in CPQONLIN is 512 GB.

To install CPQONLIN:

1. Load CPQRAID.HAM from the SmartStart CD, or from the Controller Support Software CD and diskettes. (Detailed instructions are given in the README file on the CD.)

2. Load CPQONLIN.NLM from the same source.

3. Open CPQONLIN.NLM and follow the on-screen instructions.
