1 Installation Overview The details of the steps required to install the controller depend on whether the server has an operating system installed and contains data. The flowcharts in Figure 1-1 and Figure 1-2 summarize the installation procedures for the most common scenarios. Procedure for a New System 1 Install the controller hardware (Chapter 2), if it is not preinstalled. ....... 2 Update the system firmware (Chapter 3). : 3 Update the controller firmware (Chapter 3).
Installation Overview Procedure for a Preconfigured System 1 Back up data (required if migrating from a non-array controller). ----- 2 Update the system firmware (Chapter 3). : 3 If the controller is to be the boot device, install the device driver for the operating system (Chapter 6). Otherwise, continue with step 4. : 5 Set the controller order (Chapter 4). ----- 4 Install the controller hardware (Chapter 2).
2 Installing the Hardware 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.
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.
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.
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.

3 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.
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.
4 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.
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.
5 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 s

Configuring an Array 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.
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.
Configuring an Array Running CPQONLIN 1. Enter cpqonlin at the console prompt. 2. Use the arrow keys to highlight Array Configuration Utility, and then press the Enter key. 3. From the list of controllers that is presented, select the one that you want to configure. — If no logical drives are configured for the controller, the auto-configuration wizard screen (Figure 5-2) is displayed. — If logical drives are present on the controller, the manual configuration screen (Figure 5-3) is displayed.
Configuring an Array 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. Manual Configuration Figure 5-3: Main manual configuration screen Highlight the controller, array, or logical drive that you want to configure, and then press the Enter key. The menu options for that item are shown in the panel on the right-hand side of the screen.

6 Installing the Device Drivers and Management Agents Installing the Device Drivers The drivers for the controller are located on the Support Software CD and on the SmartStart CD. Updates are posted to www.hp.com. Using the Support Software CD: Instructions for installing the drivers from the Support Software CD are given in the leaflet that is supplied with the CD. Note that the exact procedure depends on whether the server is new or already contains the operating system and user data.
Installing the Device Drivers and Management Agents You can obtain the Management CD from your local HP reseller or authorized service provider. The latest versions of Insight Manager and Management Agents are also available for download at www.hp.com/servers/manage. If the new agents do not function correctly, you may also need to update Insight Manager.
7 Upgrading or Replacing the Cache WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled. Refer to Appendix B and the Battery Replacement Notice in Appendix A before installing or removing the cache. To remove the cache module, open the DIMM ejector latches (1) on each side of the DIMM connector, and then pull the cache out of the DIMM slot (2). 2 1 This drawing represents the Smart Array 642 Controller.

D Drive Arrays and Fault Tolerance What Is a Drive Array? The capacity and performance of a single physical (hard) drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when drives fail. Connecting extra physical drives to a system increases the total storage capacity (refer to Figure D-1), but has no effect on the efficiency of read/write (R/W) operations.
Drive Arrays and Fault Tolerance With an array controller installed in the system, the capacity of several physical drives can be combined into one or more virtual units called logical drives (also called logical volumes). Then, the read/write heads of all the constituent physical drives are active simultaneously, reducing the total time required for data transfer.
Drive Arrays and Fault Tolerance S1 B1 B2 B3 S2 B4 B5 B6 S3 B7 B8 B9 S4 B10 B11 B12 Figure D-3: Data striping (S1-S4) of data blocks B1-B12 For data in the logical drive to be readable, the data block sequence must be the same in every stripe. This sequencing process is performed by the array controller, which sends the data blocks to the drive write heads in the correct order.
Drive Arrays and Fault Tolerance A1 A2 L3 L1 L4 L2 L5 Figure D-4: Two arrays (A1, A2) containing five logical drives spread across five physical drives Each logical drive in an array is distributed across all of the physical drives within the array. A logical drive can also extend across more than one port on the same controller, but it cannot extend across more than one controller. Drive failure, although rare, is potentially catastrophic.
Drive Arrays and Fault Tolerance For any configuration except RAID 0, further protection against data loss can be achieved by assigning a drive as an online spare (or hot spare). This drive contains no data and is connected to the same controller as the array. When any other physical drive in the array fails, the controller automatically rebuilds information that was originally on the failed drive to the online spare. The system is quickly restored to full RAID-level data protection.
Drive Arrays and Fault Tolerance RAID 1+0—Drive Mirroring In this configuration, data is duplicated to a second drive. B1 B1 B2 B2 B3 B3 B4 B4 P1 P2 Figure D-5: Drive mirroring of P1 to P2 When the array has more than two physical drives, drives are mirrored in pairs.
Drive Arrays and Fault Tolerance In each mirrored pair, the physical drive that is not busy answering other requests answers any read request sent to the array. (This behavior is called load balancing.) If a physical drive fails, the remaining drive in the mirrored pair can still provide all the necessary data. Several drives in the array can fail without incurring data loss, as long as no two failed drives belong to the same mirrored pair.
Drive Arrays and Fault Tolerance S1 B1 B2 P1,2 S2 B3 P3,4 B4 P5,6 B5 B6 B7 B8 P7,8 S3 S4 Figure D-7: Distributed data guarding, showing parity information (Px,y) This configuration is useful when cost, performance, and data availability are equally important.
Drive Arrays and Fault Tolerance RAID ADG—Advanced Data Guarding NOTE: Not all controllers support RAID ADG. RAID ADG is similar to RAID 5, because both methods generate and store parity information to protect against data loss caused by drive failure. With RAID ADG, however, two different sets of parity data are used, allowing data to still be preserved if two drives fail. Each set of parity data uses up a capacity equivalent to that of one of the constituent drives, as shown in Figure D-8.
Drive Arrays and Fault Tolerance Disadvantage The main disadvantage of RAID ADG is a relatively low write performance (lower than RAID 5), because of the need for two sets of parity data. Comparison of RAID Methods Table D-1 summarizes the important features of the different kinds of RAID methods described here. The decision chart in Table D-2 may help you to determine which option is best for your situation.

E Hard Drive Installation and Replacement Each drive on a SCSI bus must have a unique ID value in the range 0 to 15 (except ID 7, which is reserved for controller use). This SCSI ID value is set automatically on hot-pluggable drives in ProLiant servers and storage systems, but values for other drives must be set manually. • Do not terminate the drives. The internal cabling in ProLiant servers provides the required termination of the SCSI bus. • Do not use drives of different capacity in the same array.
Hard Drive Installation and Replacement • RAID ADG configurations can tolerate simultaneous failure of two drives. If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised and the logical drive fails. In this case, all requests from the operating system are rejected with unrecoverable errors. The “Compromised Fault Tolerance” section discusses possible ways to recover from this situation.
Hard Drive Installation and Replacement Table E-1: Hard Drive Status from LED Illumination Pattern (1) Activity (2) Online (3) Fault Meaning On, off, or flashing On or off Flashing A predictive failure alert has been received for this drive. Replace the drive as soon as possible. On, off, or flashing On Off OK to replace the drive online if the array is configured for fault tolerance and all other drives in the array are online. The drive is online and configured as part of an array.
Hard Drive Installation and Replacement There are several other ways to recognize that a hard drive has failed: • The amber LED on the front of a storage system illuminates if failed drives are inside. (Other problems such as fan failure, redundant power supply failure, or over-temperature conditions also cause this LED to light up.) • A Power-On Self-Test (POST) message lists failed drives whenever the system is restarted, as long as the controller detects one or more good drives.
Hard Drive Installation and Replacement Procedure to Attempt Recovery When fault tolerance has been compromised, inserting replacement drives does not improve the condition of the logical volume. Instead, if the screen displays unrecoverable error messages, try the following procedure to recover data. 1. Power down the entire system, and then power it back up. In some cases, a marginal drive will work again for long enough to allow you to make copies of important files. 2.
Hard Drive Installation and Replacement In general, approximately 15 minutes is required to rebuild each gigabyte.
Hard Drive Installation and Replacement CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is power-cycled, or (for a hot-pluggable drive) after the drive has been removed and reinserted. However, continued use of such marginal drives may eventually result in data loss. Replace the marginal drive as soon as possible.
Hard Drive Installation and Replacement Drive Failure During Rebuild If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error may occur. If this happens, all data on the array is lost. In exceptional cases, however, failure of another drive need not lead to a fatal system error.
Hard Drive Installation and Replacement • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (When the rebuild is complete, the Online LED on the front of the drive stops blinking.) There are some exceptions: — In RAID ADG configurations, any two drives in the array can be replaced simultaneously.
Hard Drive Installation and Replacement • Do not move an array that is configured with RAID ADG to a controller that does not support RAID ADG. Only controllers that support RAID ADG can recognize a drive array that has this configuration. When all the conditions have been met: 1. Back up all data before removing any drives or changing configuration. This step is required if you are moving data-containing drives from a controller that is not battery backed. 2. Power down the system. 3. Move the drives.
Hard Drive Installation and Replacement 2. Replace any drive. The data on the new drive is re-created from redundant information on the remaining drives. CAUTION: Do not replace any other drive until data rebuild on this drive is complete. 3. When data on the new drive has been rebuilt (the Activity LED is no longer illuminated), repeat the previous step for the other drives in the array, one at a time.
Hard Drive Installation and Replacement + Figure E-2: Array capacity expansion The unused capacity on the enlarged array can now be used to create an additional logical drive, with a different fault-tolerance setting if necessary. Alternatively, the unused capacity can be used to increase the size of one of the original logical drives; this process is logical drive capacity extension.
F Probability of Logical Drive Failure The probability that a logical drive will fail depends on the RAID level setting. If the logical drive does not have an online spare, the following results apply. • A RAID 0 logical drive fails if only one physical drive fails. • A RAID 1+0 logical drive fails if any two failed physical drives are mirrored to each other.

G Troubleshooting Several diagnostic tools are useful for troubleshooting problems with arrays. The most important are: • Array Diagnostics Utility (ADU) This utility is available as a download from the HP website. ADU error messages are listed in the Servers Troubleshooting Guide. • Power-On Self-Test (POST) Messages Smart Array controllers produce diagnostic error messages at reboot. Many of these POST messages are self-explanatory and suggest corrective actions for troubleshooting.
