1-1 Chapter 1 Features The Smart Array 3200 Controller is a dual-channel, 32-bit array controller that offers advanced features (see below). The Smart Array 3200 Controller supports Wide-Ultra2 SCSI technology for improved data transfer rates and is backwardcompatible with other SCSI devices. It also includes optional daughterboards for customizing combinations of internal and external connections (two external, two internal, or one internal and one external).
1-2 Features Other Features ■ Online spare ■ Hot-pluggable controllers and drives ■ Pre-failure warranty ■ RAID 0, 0+1 (also called RAID 10), 1, 4, and 5 support ■ Large cache − 64-MB, ECC-protected, battery-backed, removable daughterboard, read-ahead, and posted-write cache (array accelerator) ■ Adjustable cache read/write ratio ■ Tagged command queuing ■ High performance high-bandwidth SCSI channels − three independent wide-ultra SCSI-3 channels, providing a throughput of up to 120 MB/sec
1-3 About the Smart Array 3200 Controller The Smart Array 3200 Controller interface to the server is a Peripheral Component Interface (PCI) bus. The PCI bus is a high-performance, 32-bit bus with multiplexed address and data lines, and includes a parity signal. It provides a high-speed (up to 132 MB/sec) path between the system board and the controller. The Smart Array 3200 Controller is a PCI Bus Master device and conforms to Rev. 2.1 of the PCI Local Bus Specification. 2 1 5 3 Figure 1-1.
1-4 Features Using the Array Accelerator The Smart Array 3200 Controller 64-MB array accelerator provides 56-MB read/write cache, that improves data access performance to the drive array with the accelerator acting as a posted-write cache and as a read-ahead cache. The write cache can accept data from the server at a very high speed. At the same time, read and write caches can be accommodated by the drivers.
1-5 The array accelerator, with backup batteries, is located on a removable daughterboard (see Figure 1-1). For information on daughterboards, see the Smart Array 3200 Controller Installation Guide. Although controller failure is not anticipated, the Array accelerator can be detached from a Smart Array 3200 Controller and attached to a replacement Smart Array 3200 Controller.
1-6 Features The Array Configuration Utility The Array Configuration Utility is an easy-to-use, graphic-interface software program for setting up arrays and fault tolerance, and for expanding or changing drive array configurations.
1-7 Using Fault Tolerance Fault tolerance refers to the protection of data if a hardware failure occurs in the storage system. There are several methods for setting a system’s fault tolerance. Understanding each of these methods is important in determining the best method for the particular needs of your storage system.
1-8 Features Drive Movement An array of drives can be moved from one system to another. For more information, see Chapter 2, “Guidelines for Making Changes to Current Installation.” SCSI Device Support The Smart Array 3200 Controller complies with ANSI SCSI-2 standards and supports 16-bit Wide-Ultra2 SCSI, 16-bit Wide-Ultra SCSI-3, 16-bit Fast-Wide SCSI-2, and 8-bit Fast SCSI-2 (standard SCSI) devices.
2-1 Chapter 2 Guidelines for Making Changes to Current Installation Multiple Smart Array 3200 Controller Installations If you will be installing or replacing drives in your Compaq server, keep in mind that: ■ Each Smart Array 3200 Controller has two independent SCSI channels, each of which supports up to 15 drives per SCSI bus.

2-3 Determining the Maximum Storage Maximum storage capacity factors in a server include: ■ The number of option slots used for other purposes ■ The number of available internal drive bays ■ The number of logical drives or drive controllers allowed by the operating system The maximum number of controllers and drives supported depends on several factors. To determine the number of drives supported by your server, refer to your server documentation.
2-4 Guidelines for Making Changes to Current Installation Expanding or Extending the Capacity of an Array General steps for expanding the capacity of an array include: 1. Review. Refer to “Adding Storage Capacity” in Appendix E for information on expanding the storage capacity of an existing Smart Array 3200 Controller array. 2. Back up data. Although data loss is not anticipated during a normal capacity expansion, it is a good idea to back up all data in the array you will be expanding or extending.
2-5 Changing the Fault Tolerance (RAID Level) of an Array General steps for changing the Fault Tolerance (RAID Level) of an array include: 1. Decide on a Fault Tolerance (RAID Level) method. Review Appendix E, “Understanding Drive Arrays,” and determine an appropriate faulttolerance method. 2. Back up data. Although data loss is not anticipated during changing the fault tolerance, it is a good idea to back up all data on the logical drive you will be changing. 3. Change fault tolerance.
2-6 Guidelines for Making Changes to Current Installation Moving Drives CAUTION: Back up all data before removing drives or changing configurations. Failure to do so could result in permanent loss of data. Drives can be moved to alternate ID positions on the same array controller. (For information on moving arrays from one controller to another, see the “Moving Arrays” section in this chapter.
2-7 Moving Arrays CAUTION: Back up all data before removing drives or changing configurations. Failure to do so could result in permanent loss of data. Moving arrays can be just moving an array from one controller to another controller in another server. Moving arrays also refers to consolidating arrays that exist on more than one controller onto a single controller.
2-8 Guidelines for Making Changes to Current Installation Figure 2-1 shows an original distributed configuration with two controllers, each having one array: drive IDs 0, 1, 2, and 3 constitute Array A on Controller 1 and drive IDs 0 and 1 constitute Array A on Controller 2. Figure 2-2 shows that after removing the array from Controller 2 and adding it to Controller 1, Controller 1 now has two arrays: drive IDs 0, 1, 2, and 3 constitute Array A and drive IDs 4 and 5 constitute Array B.
2-9 To move an array, make sure all required conditions are satisfied, then: 1. Power-down the system. 2. Move array (including all drives in the array). 3. Power-up the system. A 1727 POST message should indicate that logical drives were added to the configuration. If a 1785 (Not Configured) POST message is displayed, turn the system off immediately to avoid data loss and return the drives to their original locations.
2-10 Guidelines for Making Changes to Current Installation Restoring an Array to Its Original Controller If you moved an array from one controller to another, you can restore it to its original controller. Figures 2-3 through 2-5 show the consecutive configurations required to restore an array to its original controller (or to a replaced controller in the event of controller failure).
2-11 Controller 1 Controller 2 ID5 ID5 ID4 ID4 ID3 d ID3 ID2 c ID2 z ID1 b ID1 y ID0 a ID0 x Figure 2-5. Array A Array A Failed arrays removed; arrays on separate controllers To restore an array to its original controller, make sure the conditions for moving drives are met. Then: IMPORTANT: These steps must be followed AS DESCRIBED. Any deviation or mistake could result in the loss of all data across all moved arrays. 1. Power-down the system. 2.
3-1 Chapter 3 Updating the Firmware The ROMs on all Compaq servers and most Compaq options can be updated easily. By programming the ROM using a special Compaq utility called ROMPaq, the existing contents of the ROM are replaced with another version stored in a disk file. This conveniently distributes new firmware to keep Compaq products updated with the latest capabilities. There are two ROMPaq utilities: System ROMPaq Updates the system ROM in all Compaq servers supporting Flash ROM.
3-2 Updating the Firmware Materials Needed To create the ROMPaq utility diskette(s), you will need: ■ Compaq SmartStart and Support Software CD (supplied in the Smart Array 3200 Controller option kit) ■ Ten to fifteen blank diskettes for SystemsROMPaq and Options ROMPaq ■ Access to a server or workstation with a bootable CD-ROM drive. This can be the system in which you are installing the Smart Array 3200 Controller. Creating Diskettes To create ROMPaq diskettes: 1.
3-3 Running Systems ROMPaq System ROMPaq updates the firmware in Compaq servers. The Smart Array 3200 Controller has enhanced drive array capabilities; many servers may need updated firmware to take advantage of these capabilities. Since it is difficult to determine when the firmware needs to be updated, Compaq recommends that you run the latest System ROMPaq on all servers when installing a new Smart Array 3200 Controller.
3-4 Updating the Firmware To run System ROMPaq: 1. Place the System ROMPaq diskette in the server diskette drive. 2. Boot the server by turning on the power. 3. Press Enter at the Welcome screen. 4. At the Select A Device screen, select the server from the list of the programmable devices. This may be the only item in the list. Press Enter. 5.
3-5 Running Options ROMPaq Options ROMPaq updates the firmware on Compaq options. Since it is difficult to determine when to update the firmware, Compaq recommends that you run the latest Options ROMPaq on all Smart Array 3200 Controllers whenever new versions are released. The Smart Array 3200 Controller firmware version on the Compaq SmartStart and Support Software CD has already been installed; you do not need to update immediately.
3-6 Updating the Firmware 5. If the ROM firmware for the Smart Array 3200 Controller is the same or newer than that on the Options ROMPaq diskette, you will get the message: The ROM image files found for the device selected are not newer than the current ROM image Press Enter to go to step 9.
3-7 8. When Options ROMPaq finishes reprogramming Smart Array 3200 Controller ROM, press Enter if you want to reprogram another Compaq option. Repeat steps 4 through 7. 9. If you are finished with reprogramming options, press Esc to exit the ROMPaq utility. 10. Remove the Options ROMPaq diskette and reboot the server by cycling the power (cold boot). To upgrade additional options in the server, repeat Steps 2 through 9 by booting from each Options ROMPaq diskette in succession.
4-1 Chapter 4 Running the System Configuration Utility The Compaq System Configuration Utility provides easy configuration of hardware installed in or connected to the server. This utility detects each hardware device and configures the server to work with it.
4-2 Running the System Configuration Utility If your server does not have a bootable CD-ROM drive, you can create diskettes of the latest version of the System Configuration Utility from the Compaq SmartStart and Support Software CD. See the following section, “System Configuration Diskettes,” for instructions on creating the diskettes. If your server has a bootable CD-ROM drive, proceed to “Running the System Configuration Utility.
4-3 Running the System Configuration Utility To run the System Configuration Utility: 1. Place the Compaq SmartStart and Support Software CD in the server CD-ROM drive. or Place the System Configuration Utility Diskette 1 in the server floppy drive. 2. Reboot the server. 3. During the boot process, several messages appear. Among these are a notice that one or more Smart Array 3200 Controllers were detected in option slots and a recommendation to run the System Configuration Utility. 4.
4-4 Running the System Configuration Utility Configuring the Controller The steps in this section include editing Controller Order and Online Recovery Server Status parameters. To make the correct selections, the parameters are discussed below. Controller Order Select the order in which you want this Smart Array 3200 Controller to be recognized. All hard disk controllers, including the integrated controller on the system board, must be assigned a unique order number.
4-5 When installing a Smart Array 3200 Controller in a system with an existing array controller, you can either place the new controller at the end of the controller order or reorder the controllers. Reordering changes the current drive letter assignments for all drives on the system. To avoid changing drive letter assignments, place the new controller at the end of the controller order. IMPORTANT: Do not create a primary partition on any of the added disks.
4-6 Running the System Configuration Utility Configuration Steps 1. Edit these parameters for Smart Array 3200 Controller: Controller Order Under Advanced Features: Online Recovery Server Status Press Enter to select the parameter to edit. 2.

From this screen you can reconfigure a currently configured logical drive to a new fault-tolerance (RAID) level or a new stripe size. Error and Warning Messages When you start the Array Configuration Utility, the software checks each controller to detect errors in its configuration.
5-30 Running the Array Configuration Utility NetWare Online Array Configuration Utility (CPQONLIN) The NetWare Online Array Configuration Utility, also called CPQONLIN, is an NLM for configuring your drive arrays without shutting down your server. CPQONLIN also provides information about the status of drives attached to the Smart Array 3200 Controller. It indicates drive failure, expansion, or waiting for expansion or rebuild (queued). Before loading CPQONLIN.
5-31 Custom Configuration Custom configuration allows you to create arrays and to assign fault tolerance one array at a time. To custom configure an array, make selections from the Main Configuration View screen. Highlight the controller, array, or logical drive you want to configure. Make a selection from the Options menu located on the right side of the screen. Figure 5-24 shows the controller highlighted on the left side of the screen and Controller Options on the right side of the screen. Figure 5-24.
5-32 Running the Array Configuration Utility Drive Rebuild, Expand Priority, and Accelerator Ratio To set the drive rebuild priority, expand priority, or accelerator ratio for a controller, highlight the controller at the Main Configuration View screen and select the Controller Settings option listed below Controller Options. The Controller Settings screen appears (Figure 5-25). Figure 5-25.
5-33 Accelerator Ratio The Smart Array 3200 Controller has an onboard cache, called an Array Accelerator, that performs both write-posting and read-ahead caching. The setting in CPQONLIN determines the amount of memory allocated to the read and write caches. For example, if the Accelerator Ratio is set to Read 75% Write 25%, then 75% of Array Accelerator cache is dedicated to read-ahead cache and 25% is dedicated to the write-posting cache.
5-34 Running the Array Configuration Utility Failed Drives or Interim Recovery Mode If a drive fails and hardware fault tolerance is enabled, operation continues. Replace the drive as soon as possible. Select a logical drive and press F3 to monitor the status of drive recovery (Figure 5-26). Figure 5-26. Rebuilding logical drive screen ■ Interim Recovery: The logical drive is operating, but a failed drive has not been replaced. Replace drive as soon as possible.
5-35 If you do not replace the failed drive, the only option using the Array Configuration Utility is to delete logical drives. Do not delete logical drives that contain valid data. Doing so results in lost data. NOTE: A failed status can occur on drives protected by fault tolerance if two or more physical drives fail concurrently. Some status indicators are available without pressing F3. For example, on the Main menu, the FAILED status will appear next to the logical drive that has failed.
5-36 Running the Array Configuration Utility Optimizing Array Controller Performance To improve system performance, keep these tips in mind before creating NetWare volumes or partitions: ■ If you selected a fault-tolerance option, such as mirroring or distributed data guarding, when using the Compaq System Configuration Utility, do not select mirroring while using INSTALL.NLM.
5-37 Using CPQDAOPT on NetWare Servers NOTE: 1. Start your NetWare server. NOTE: 2. Back up existing data before applying new settings to data volumes. The following steps are meant as an example. Copy the CLIB.NLM and STREAMS.NLM files from the NetWare Installation CD-ROM (D:\ NETWARE.312\________\C where the line represents eight underscores) to the server’s DOS partition before you begin installation. NOTE: CLIB.NLM must be v3.11c or later. 3. Be sure you load CPQDA386.DSK (version 3.
5-38 Running the Array Configuration Utility 8. If there are no existing partitions, load the NetWare installation utility and select the option to create disk partitions. 9. Use the formula recommended by CPQDAOPT to determine the number of Hot Fix Redirection Blocks for the partition installed on the selected device. Make sure that the number of blocks is the same as described by the formula. For example, if the formula was “even,” any even number will work. 10.
6-1 Chapter 6 Installing the Operating System Drivers This chapter outlines driver installation steps to set up the Smart Array 3200 Controller in a server running any of the following operating systems: ■ Novell NetWare 3.2, 4.2, and 5.0 ■ Microsoft Windows NT 3.51 and 4.0 ■ SCO OpenServer 5 ■ SCO UnixWare 2.x and 7.x ■ IBM OS/2 WARP Server family ■ Banyan VINES 6.x, 7.x, and 8.
6-2 Installing the Operating System Drivers Novell NetWare 3.2, 4.2, and 5.0 Use the instructions in this section to install the driver for a new Smart Array 3200 Controller installation or to upgrade the driver in a server running NetWare and using the Smart Array 3200 Controller. If you use SmartStart to install NetWare and drivers, you do not need to create the Novell Support Software Diskettes (SSD). Skip to the section, “Using the Array Configuration Utility for NetWare.
6-3 Creating Novell SSD Diskettes Use the CPQARRAY.HAM driver for the Smart Array 3200 Controller. These drivers are on the Novell SSD Diskettes. NOTE: To determine the appropriate driver for your version of NetWare, see the online help file on Disk 2 of the Novell SSD. To create the diskettes: 1. Boot the server from the Compaq SmartStart and Support Software CD. 2. From the Compaq System Utilities screen, select Create Support Software. 3.
6-4 Installing the Operating System Drivers Additional Information The Novell SSD SmartStart CD contains the latest information about using Compaq options in a NetWare environment, including the driver installation procedure. Locate and read this procedure. If the procedure differs from the one described here, follow the one in the STORAGE.RDM file on the Novell SSD diskette. To view and print the readme files: 1. Execute README.COM C:\readme 2. Select the file(s) to read or print.
6-5 NetWare 3.12, 4.2, and 5.0 Driver Installation from Novell SSD Compaq provides an installation script on the Novell SSD that integrates Novell’s INSTALL.NLM Product Options menu option. Use this option to install or automatically upgrade Compaq storage adapter and device drivers. The drivers are copied from the Novell SSD to both the DOS server startup directory (typically C:\NWSERVER) and to the SYS:SYSTEM directory. To install the driver for the Smart Array 3200 Controller: 1. Load INSTALL.
6-6 Installing the Operating System Drivers Updating the Compaq Insight Manager Agents If you are using Compaq Insight Manager, you will need to update the Insight Agents to support the new Smart Array 3200 Controller. If you used SmartStart 4.22 or later to install the operating system on a new Smart Array 3200 Controller installation or to upgrade the driver in an existing installation, the agents were manually updated automatically by SmartStart. You will not need to update the agents.
6-7 Handling Disk Drive Failures Although drive failures are not common, it is important to protect your critical data. The best way to recover from a failed drive is to configure your drive system with some form of fault tolerance. To ensure a quick and transparent recovery, Compaq recommends that you configure your Smart Array 3200 Controller with hardware fault tolerance.
6-8 Installing the Operating System Drivers DOS Partitions and NetWare Fault Tolerance NetWare does not mirror information on DOS partitions. Only hardware fault tolerance supports mirrored DOS partitions. If you have a mirrored drive containing a DOS partition, you need to restore the DOS partition information from another back-up source. If the failed drive contains a DOS partition, NetWare cannot access information on that partition. For example, files on the DOS partition include STARTUP.
6-9 7. Set the active partition to the DOS partition you just created. 8. Use the FORMAT command to format the DOS partition to include the necessary files to make the partition bootable. For example: FORMAT C: /s 9. If you have a backup of your DOS partition, use it to create the previous image. Otherwise, use your NetWare server diskettes and copy the following files to a NetWare directory on your DOS partition: SERVER.EXE INSTALL.NLM VREPAIR.NLM MONITOR.NLM CLIB.NLM STREAMS.NLM 10.
6-10 Installing the Operating System Drivers Recovering Drives Configured for NetWare Fault Tolerance If you have chosen no fault tolerance for the drives connected to your Smart Array 3200 Controller and have configured NetWare mirroring or NetWare controller duplexing, perform the following steps to recover the data after a drive failure: 1. Identify the failed physical drive that caused the NetWare device to be deactivated. Record the device number and device name of the failed logical drive.
6-11 6. Insert the replacement physical drive in the drive bay where the failed drive was located. The physical drive must be of the same capacity as the failed drive. Be sure that all cable connections are secure. For replacements in a ProLiant server or storage system, after you secure the drive in the bay, the LEDs on the drive each light once in an alternating pattern to indicate that the connection was successful.
6-12 Installing the Operating System Drivers 11. Use the Insert key to resynchronize this partition. You must resynchronize before deleting the partition. Allow INSTALL to resynchronize this partition. If warning messages indicate the selected partition contains an already-defined volume, select No (do not rename the volume) and press Esc. Since you will delete this partition, there is no reason to salvage the volume. Proceed with deleting the partition table. 12. From the INSTALL.
6-13 Recovering Drives Configured for No Fault Tolerance If you configured no fault tolerance, you must recover the data from a backup media. Perform the following steps: 1. Identify the failed physical drive that caused the logical drive to be deactivated. Record the device number and device name of the failed logical drive. For example: NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT Failure messages are recorded on the server console.
6-14 Installing the Operating System Drivers 4. It may be possible to use the INSTALL.NLM option Change Hot Fix to determine the number of Hot Fix Redirection blocks set up for this partition. Otherwise, refer to the section “Using CPQDAOPT on NetWare Servers,” in Chapter 5 for more information about optimizing the performance. NOTE: Even though the logical drive may have a valid partition table, the data on this logical drive is no longer valid.
6-15 Microsoft Windows NT 3.51 and 4.0 This section includes instructions for installing the initial driver for a new Smart Array 3200 Controller installation or for upgrading the driver in an existing Windows NT server/Smart Array 3200 Controller system. If you used SmartStart to install Windows NT and drivers on a new server, you do not need to make the Support Software Diskette (SSD) utility diskettes. Skip this section.

If you did not use SmartStart 4.
6-26 Installing the Operating System Drivers Getting the Driver and Installation Information The latest drivers and support files for SCO OpenServer 5 and information about installing the driver are on the Compaq SmartStart and Support Software CD supplied with the Smart Array 3200 Controller option kit. To access these files, create a set of Compaq EFS for OpenServer 5 diskettes from the Compaq SmartStart and Support Software CD.
6-27 Accessing the Information Driver installation procedures for SCO OpenServer 5 from Compaq and SCO OpenServer 5 (non-Compaq) are different. Choose the correct procedure below. Servers Running Compaq SCO OpenServer 5 To access the driver installation information in systems running SCO OpenServer 5 from Compaq: 1. Place the diskette labeled SCO Installation Notes for Compaq Servers in the diskette drive of a server or PC capable of reading a DOS text file. 2.
6-28 Installing the Operating System Drivers Updating the Compaq Insight Manager Agents If you are using Compaq Insight Manager, you will need to update the Insight Agents to support the new Smart Array 3200 Controller. If you used SmartStart 4.22 or later to install the operating system on a new Smart Array 3200 Controller installation or to upgrade your driver in an existing installation, the agents were updated by SmartStart; you will not have to manually update the agents.
6-29 Materials Needed To create a set of Compaq EFS for SCO UnixWare diskettes, you will need: ■ Compaq SmartStart and Support Software CD (supplied in the Smart Array 3200 Controller option kit) ■ Blank diskettes ■ Access to a server or workstation with a bootable CD-ROM drive. This may be the system in which you are installing the Smart Array 3200 Controller. Creating the EFS Diskettes To create the Compaq EFS for SCO UnixWare diskettes: 1.
6-30 Installing the Operating System Drivers Updating the Compaq Insight Manager Agents If you are using Compaq Insight Manager, you will need to update the Insight Agents to support the new Smart Array 3200 Controller. If you used SmartStart 4.22 or later to install the operating system on a new Smart Array 3200 Controller installation or to upgrade your driver in an existing installation, the agents were updated by SmartStart; you will not have to manually update the agents.
6-31 Creating SSD Diskettes The OS/2 driver for the Smart Array 3200 Controller is located on the Compaq SmartStart and Support Software CD (supplied in the Smart Array 3200 Controller option kit). To access the driver, create the OS/2 SSD diskettes. These diskettes contain the latest operating system software, drivers, and documentation for all Compaq equipment supported by OS/2. To create the diskettes: 1. Boot the server from the Compaq SmartStart and Support Software CD. 2.
6-32 Installing the Operating System Drivers Additional Information Readme files with the latest information about OS/2, including the driver installation procedure, are on the OS/2 SSD diskettes. Locate and read this procedure. If the procedure differs from that which is shown here, follow the one on the SSD diskettes. To view or print the Readme files, you will need a server with a DOS partition or a PC running DOS or Windows: 1. Place the OS/2 SSD diskettes in the floppy drive. 2.
6-33 Installing the Driver To install the driver file to the OS/2 directory on your boot drive: 1. Place the OS/2 SSD diskettes in the floppy drive. 2. From the OS/2 command prompt, change the drive to A: by typing: a: Then type: Ddinstal 3. Click the Change button to change the source directory to A:/ADD. 4. Select Compaq Array Driver for OS/2 from the list of drivers. Click OK to continue. 5. The CPQARRAY.ADD driver file will be copied to the x:\os2 directory (where x is the boot drive).
6-34 Installing the Operating System Drivers Controller Ordering The order in which the ADD driver appears in the CONFIG.SYS file determines how each type of controller is ordered, relative to other types of controllers. Each type of controller that a single ADD driver controls will be grouped together. The first ADD driver to appear in the CONFIG.SYS file will have its controllers ordered first, the second ADD driver will have its controllers ordered after the first driver, and so on.
6-35 Partitioning The following are limitations for OS/2 on any computer system: ■ Any FAT partition cannot be larger than 2 GB (2048 MB) in size. ■ It is recommended that you do not exceed 8 GB for an HPFS boot partition. Exceeding this size makes it possible for the OS/2 system files to end up larger than 8 GB on the disk. This prevents the ROM from loading the system files at boot time. ■ This driver has been tested with HPFS partition sizes of up to 40 GB.
6-36 Installing the Operating System Drivers Booting OS/2 from a Smart Array 3200 Controller This section includes information on booting a system from a Smart Array 3200 Controller. The CPQARRAY.ADD driver must be present when booting from a Smart Array 3200 Controller (the Compaq IAES is not a bootable device). If a Smart Array 3200 Controller is the primary disk controller, edit the CONFIG.SYS file and make sure the BASEDEV=CPQARRAY.ADD entry in the file is the first BASEDEV entry.
6-37 Command Line Switches Several command line switches are available to modify the standard behavior of the Compaq ADD driver. The syntax of the command line switches is: 1. /PERF:[memory blocks] This command line switch is a non-standard switch implemented for the CPQARRAY.ADD to modify the performance characteristics of the driver when using a Smart Array 3200 Controller.
6-38 Installing the Operating System Drivers 3. /A:[adapter index] [unit parameters] This is a standard command line switch that causes the driver to modify its behavior toward adapters. [adapter index] is a number used to identify a controller. The index is based on “0” for the lowest controller order number associated with the adapter controlled by this ADD. The index increases by one for each controller in the system as you move up the controller configuration order.
6-39 Ignore the specified adapter; do not control the adapter with this driver. This parameter prevents the ADD driver from recognizing the specified adapter. Use this parameter to enable another driver to control a specific adapter. IMPORTANT: Do not ignore the primary controller or boot controller. The system will not boot. IMPORTANT: The driver must be loaded by a BASEDEV= statement in the CONFIG.SYS file. This statement is inserted automatically by the ADDARRAY.CMD installation procedure.
6-40 Installing the Operating System Drivers Updating the Compaq Insight Manager Agents If you are using Compaq Insight Manager, you will need to update the Insight Agents to support the new Smart Array 3200 Controller. If you used SmartStart 4.22 or later to install the operating system on a new Smart Array 3200 Controller installation or to upgrade your driver in an existing installation, the agents were updated by SmartStart. You will not have to manually update the agents.

D-2 Things You Should Know Smart Array 3200 Controller Option Kit Contents 1 2 3 5 6 4 Figure D-1.
D-3 SCSI Termination All SCSI buses require termination on both ends of the bus to prevent signal degradation. The Smart Array 3200 Controller supplies the termination on the origination end of the SCSI bus. All internal SCSI cabling recommended for Compaq servers provides the necessary termination for the opposite end of the bus. Therefore, individual SCSI drives in Compaq servers should not contain bus termination. External SCSI devices must also provide termination for the SCSI bus.
D-4 Things You Should Know SCSI Cabling The cables available from Compaq that connect your Smart Array 3200 Controller option board to SCSI drives in any Compaq server or external SCSI product can be found: ■ In the Smart Array 3200 Controller Installation Guide ■ At www.compaq.com ■ In the Setup and Installation Guide or Reference Guide that accompanied your server.
D-5 SCSI Cable Connectors To help identify the SCSI cables required for a Smart Array 3200 Controller installation in the various configurations of Compaq servers, refer to Figure D-2. Keep in mind these characteristics of SCSI cables: ■ External SCSI cables have a round wire with securable connectors. ■ Internal SCSI cables have a flat ribbon wire with push-on connectors. ■ Compaq SCSI cables are keyed so that they cannot be installed incorrectly.
D-6 Things You Should Know Migrating to/from Other Controllers The table below indicates what actions, if any, are required when migrating from one array controller type to another. NOTE: Compaq recommends that you should back up data any time you move drive arrays or change your configuration.
E-1 Appendix E Understanding Drive Arrays This chapter explains drive array concepts, data protection methods (including fault-tolerance options), and data reliability features of the Smart Array 3200 Controller. The following general information will help you understand terms and concepts required for configuration. What is a Drive Array? A drive array is a collection of hard disk drives or physical drives that are grouped together to create an array of physical drives.
E-2 Understanding Drive Arrays A drive array can also consist of a single logical drive, as illustrated in Figure E2. Physical Drive 1 Physical Drive 2 Physical Drive 3 Logical Drive 1 Drive Array Daz-9-18.EPS Figure E-2. Drive array with one logical drive Figure E-3 illustrates a larger array with two logical drives across six physical drives. Drive 1 Drive 2 Physical Drives Drive 3 Drive 4 Drive 5 Drive 6 Logical Drive 1 Logical Drive 2 Drive Array Daz-9-16.EPS Figure E-3.
E-3 The same physical drives may also be arranged into separate arrays, as illustrated in Figure E-4. Both arrays can be handled by the same controller. Physical Drives Drive 1 Drive 2 Drive Array 1 Drive 3 Logical Drive 1 Drive 4 Drive 5 Drive Array 2 Drive 6 Logical Drive 2 Daz-9-17.EPS Figure E-4.
E-4 Understanding Drive Arrays Logical Drives A logical drive is storage space that is distributed across all physical drives in an array (except for online spares). Refer to Figure E-3. Distributing the storage space provides these advantages: ■ Data can be accessed on all the physical drives at once, resulting in much higher-performance data storage and retrieval. ■ Fault-tolerance methods can be used to protect your data against hardware failures.
E-5 Drive Array Benefits Using drive arrays with the Smart Array 3200 Controller has several important benefits: ■ Data Protection ■ Performance Enhancement ■ Capacity Changes ■ Data Reliability Data Protection The Smart Array 3200 Controller provides several options to produce data redundancy for a more reliable system including distributing data, faulttolerance methods, assigning online spares, and rebuilding data.
E-6 Understanding Drive Arrays Table E-1 RAID Level Characteristics Distributed Data Guarding (RAID 5) Data Guarding (RAID 4) Mirroring (RAID 1) No Fault Tolerance (RAID 0) Usable Disk Space* 67% to 97% 67% to 97% 50% 100% Disk Space Formula (n = no. of drives) (n-1)/n (n-1)/n n/2 n Parity and Data Redundancy Parity distributed over each drive Dedicated parity drive Duplicate data None Minimum Number of Drives 3 3 2 1 Tolerant of multiple, simultaneous drive failures.
E-7 Distributed Data Guarding (RAID 5) Distributed data guarding, also called RAID 5, stores parity data across all the drives in the array. Spreading the parity across all the drives enables more simultaneous read operations and higher performance than data guarding (RAID 4). If a drive fails, the controller uses the parity data and the data on the remaining drives to reconstruct data from the failed drive.
E-8 Understanding Drive Arrays Data Guarding (RAID 4) Data guarding, also called RAID 4, assures data reliability while using only a small percentage of the logical drive storage capacity. A designated, single drive contains parity data. If a drive fails, the controller uses the data on the parity drive and the data on the remaining drives to reconstruct data from the failed drive. This allows the system to continue operating with slightly reduced performance until you replace the failed drive.
E-9 The Smart Array 3200 Controller supports RAID 4 for backward compatibility. Because RAID 5 provides the same benefits with higher performance, Compaq recommends using RAID 5 instead of RAID 4. Drive Mirroring (RAID 1) Drive mirroring, also called RAID 1, is the highest-performance fault-tolerance method. RAID 1 is the only method for fault-tolerance protection if only two drives are installed or selected for an array.
E-10 Understanding Drive Arrays No Fault Tolerance (RAID 0) RAID 0 does not provide fault tolerance. This level of RAID stripes data across all the drives in the array, but it does not incorporate a method to create redundant data. Therefore, if you choose this RAID option for any of your logical drives, you will experience data loss for that logical drive if one physical drive fails.
E-11 Performance Enhancement Drive arrays enable data access performance to be dramatically enhanced over non-arrayed drives. In addition, the Smart Array 3200 Controller has several other performance enhancement features that are discussed in this section. Distributing Data and Data Striping Distributing data makes it possible to access data concurrently from multiple drives in an array. This yields I/O rates many times faster than non-arrayed drives. Data striping allows data distributing.
E-12 Understanding Drive Arrays For example, consider an operating system that typically requests data in 32-sector blocks (a sector contains 512 bytes of data). The Smart Array 3200 Controller distributes the data so that the first 32 sectors of data are on the first drive in the array. The Smart Array 3200 Controller continues distributing the next 32 sectors on the second drive, the next 32 sectors on the third drive, and so on.
E-13 User Selectable Stripe-Size You can change stripe-size either during the initial configuration of the system, or later, after the system has been in use for some time. In both cases this must be performed offline. See Chapter 5 for instructions to set or change stripe-size. Table E-2 lists the set of valid stripe sizes for each RAID level highlighting the default values.
E-14 Understanding Drive Arrays The number of sectors on the physical drives can not be increased. This can occur as a result of a request to increase stripe-size; the newly selected stripesize would not be allowed. For example, if the end user desires to change the stripe-size from 32 to 256 sectors, there may not be enough sectors at the end of the disks for a complete stripe of the larger size. Since a partial stripe cannot be supported, the request would not be allowed.
E-15 Data Protection The Array Accelerator was designed to protect data integrity. Batteries and ECC memory protect the cache memory. This allows end users to take full advantage of the performance without sacrificing reliability. The Array Accelerator is also removable. This, along with its integrated batteries, means the Array Accelerator can be removed from one Smart Array 3200 Controller and installed on another.
E-16 Understanding Drive Arrays Batteries The Array Accelerator contains batteries that maintain any data cached there if a system power failure occurs. The batteries can preserve data in the Array Accelerator for up to four days. When power is restored to the system, an initialization process writes the preserved data to the disk drives. The cells used in the Array Accelerator batteries are recharged with a “trickle” charge applied while system power is present.
E-17 Concurrent I/O Request Servicing The Smart Array 3200 Controller can service hundreds of I/O requests at a time. For example, if you request data that resides on the first drive and another end user requests data that resides on the second drive, the controller delivers both pieces of information concurrently. Figure E-9 illustrates concurrent request servicing. User 1 Request Figure E-9.
E-18 Understanding Drive Arrays Bus Master Data Transfers The Smart Array 3200 Controller is a bus master device that takes control of the PCI bus during high-speed transfers. This allows the system processor to handle application processing or other types of tasks. Data transfer occurs at rates of up to 133 MB/sec for the PCI bus.
E-19 Extending the capacity of an existing logical drive can be performed offline by backing up all data, reconfiguring the array, and restoring the data. To extend capacity online, your operating system must support a logical drive increasing in size. When initiated by the Array Configuration Utility, the Smart Array 3200 Controller automatically redistributes the data in the original logical drive to a logical drive that spans all of the physical drives in the array, including the added drives.
E-20 Understanding Drive Arrays The Smart Array 3200 Controller equally redistributes the data to all the drives, using the same fault-tolerance method as the original configuration. The first logical drive remains first, but it now spans 14 drives instead of 10.
E-21 Online Capacity Expansion or Extension In certain cases, the Smart Array 3200 Controller and the Array Configuration Utility also facilitate storage capacity changes online, without downing the server or storage system. These cases are: ■ 1 Windows NT or NetWare operating system (NetWare 3.
E-22 Understanding Drive Arrays Other Fault-Management Features The Smart Array 3200 Controller and the network operating system support several other fault-management and data-reliability features, including: ■ Auto-reliability monitoring ■ Dynamic-sector repairing ■ Drive-parameter tracking ■ Drive-failure alert features ■ Interim data recovery ■ Automatic data recovery ■ Hot-plug drives (Compaq ProLiant Storage System, Compaq ProLiant Server, Rack-Mountable Compaq ProLiant Storage System or
E-23 Auto-Reliability Monitoring Auto Reliability Monitoring (ARM) is a background process that scans hard drives for bad sectors in fault-tolerant logical drives. ARM also verifies the consistency of parity data in drives with data guarding or distributed data guarding. This process assures that you can recover all data successfully if a drive failure ever occurs. ARM operates only when you select RAID 1, RAID 4, or RAID 5.
E-24 Understanding Drive Arrays Interim Data Recovery In RAID 5, RAID 4, or RAID 1 fault-tolerant configurations, if a drive fails, the system continues to operate in an interim data recovery mode. For example, if you selected RAID 5 for a logical drive with four physical drives and one of the drives fails, the system continues to process I/O requests, but at a reduced performance level. Replace the failed drive as soon as possible to restore performance and full fault tolerance for that logical drive.
E-25 Hot Pluggable Drives The Smart Array 3200 Controller, used with a Compaq ProLiant Storage System, a Rack-Mountable Compaq ProLiant Storage System, a Compaq ProLiant server, or Rack-Mountable Compaq ProLiant server, supports hot-plug drives. You can install or remove these drives without turning off system power. This feature is a function of the Compaq ProLiant Storage System and the Compaq ProLiant server and operates independently of the operating system.

E-27 Controller Duplexing Some operating systems support controller duplexing, a fault-tolerance feature that requires two Smart Array 3200 Controllers. With duplexing, the two controllers each have their own drives that contain identical data. In the unlikely event of a Smart Array 3200 Controller failure, the remaining drives and the Smart Array 3200 Controller service all requests. Controller duplexing is not the same as duplexing the SCSI buses on a single Smart Array 3200 Controller.
E-28 Understanding Drive Arrays Software-Based Drive Mirroring Some operating systems support software-based drive mirroring as a faulttolerance feature. Software drive mirroring resembles hardware-based drive mirroring (RAID 1), except that the operating system mirrors logical drives instead of physical drives. A pitfall of software-based drive mirroring is that the operating system believes each logical drive is a separate physical drive.
F-1 Appendix F Replacing the Array Accelerator The Smart Array 3200 Controller has a removable 64-MB Array Accelerator. The Array Accelerator is mounted on a removable daughterboard so it can be easily replaced if necessary. The Smart Array 3200 Controller is not operable without the Array Accelerator.
F-2 Replacing the Array Accelerator Removing the Array Accelerator To remove the optional Array Accelerator from the controller board: 1. Twist the latch 1 90° to allow the standoff to pull through the controller board. 2. Carefully pull the Array Accelerator daughterboard away 2 from the Smart Array 3200 Controller board, unplugging the signal connectors. 1 Figure F-1.
F-3 Installing the Array Accelerator To install the Array Accelerator board on the Smart Array 3200 Controller: 1. Align the connectors and plug the Array Accelerator board onto the Smart Array 3200 Controller 1. Be sure the connectors are fully mated by squeezing the boards together at the connector side. 2. Align the plastic standoff on the Array Accelerator board with the slot in the Smart Array 3200 Controller board.
G-1 Appendix G Upgrading from the SMART-2 and SMART SCSI Array Controllers End users of the original Compaq SMART-2 or SMART SCSI Array Controllers can consider upgrading to the new Smart Array 3200 Controller. This appendix provides upgrade instructions for moving arrayed drives from either the SMART or SMART-2 (SMART-2/E, SMART-2/P, SMART-2SL, and SMART-2DH) Controllers to the Smart Array 3200 Controller. All end user data and configuration information will be retained after the upgrade process.
G-2 Upgrading from the SMART-2 and SMART SCSI Array Controllers 3. Upgrade your System ROM to the most current version using the Compaq System ROMPaq. The System ROM must be upgraded before installing the Smart Array 3200 Controller. Your Smart Array 3200 Controller option kit may include a diskette containing Systems ROMPaq. If so, use the diskette to upgrade the system ROM.
G-3 The Smart Array 3200 Controller has two Very High Density Connector Interface (VHDCI) connectors on the mounting bracket for Ports 1 and 2. Optional daughterboards (included in the Smart Array 3200 Controller option kit) provide one or two 68-pin Wide-Ultra SCSI3 connectors for internal drives. This provides SCSI ports externally, internally, or both, without additional cabling to route internal channels externally or vice versa. There is no Y cable required for the Smart Array 3200 Controller.

OR External VHDCI-to-Wide cable required for connection to ProLiant Storage systems.
G-6 Upgrading from the SMART-2 and SMART SCSI Array Controllers The Smart Array 3200 Controller uses two VHDCI external and two 68pin Fast-Wide SCSI-2 internal connectors on optional daughterboards; therefore: ❏ If you are connecting to Fast-SCSI-2 internal drives, you must attach a 68-pin to 50-pin cable adapter (included in the Smart Array 3200 Controller option kit) to an internal connector on the optional daughterboard to use your existing 50-pin internal ribbon cable.
G-7 7. Reconnect all internal and external drive cables. Pay close attention to the port numbers as noted in Step 5. 8. Turn on the server and run the Compaq System Configuration Utility. This configuration utility recognizes the Smart Array 3200 Controller and allows you to change parameters such as controller order and interrupt number, if needed.
H-1 Appendix H Recovering from Drive Failure The purpose of fault-tolerant configurations on the Smart Array 3200 Controller is to protect against data loss due to drive failure. Although the Smart Array 3200 Controller firmware is designed to protect against normal drive failure, it is imperative that the correct actions are performed to recover from a drive failure without inadvertently inducing any additional drive failures.
H-2 Recovering from Drive Failure Fault Tolerance and Drive Failure In the event of a drive failure, the condition of the logical drive varies, depending upon the fault-tolerance method used. Since a single array of physical drives can contain multiple logical drives with different fault-tolerance methods, conditions of each logical drive on the same array are not necessarily the same.
H-3 Spare Drives In the event of a drive failure, if a spare drive is assigned and available, the spare drive acts as an immediate replacement for the failed drive. Data is reconstructed automatically from the remaining drive(s) in the volume and written to the spare drive through the Automatic Data Recovery process. Once the spare drive is completely built, the logical drive again runs at full fault tolerance and is then able to sustain another subsequent drive failure.
H-4 Recovering from Drive Failure The capacity of replacement drives must be at least as large as the capacity of the other drives in the array. Drives of insufficient capacity will be failed immediately by the controller without starting the Automatic Data Recovery. CAUTION: If the Smart Array 3200 Controller has a failed drive, replace this drive with a new or known-good replacement drive.
H-5 Automatic Data Recovery Failure During Automatic Data Recovery, if the online LED of the replacement drive stops blinking and all other drives in the array are still online, the Automatic Data Recovery process may have abnormally terminated due to a noncorrectable read error from another physical drive during the recovery process. The background Auto-Reliability Monitoring process helps prevent this problem, but it cannot do anything about certain issues, such as SCSI bus signal integrity problems.
H-6 Recovering from Drive Failure Compromised Fault Tolerance If fault tolerance is compromised because of failure of multiple drives, the condition of the logical drive will be “failed,” and “unrecoverable” errors will be returned to the host. Data loss is probable. Inserting replacement drives at this time will not improve the condition of the logical drive. If this occurs, first try turning the entire system off and on.

J-1 Appendix J Questions and Answers This appendix includes common questions about the Smart Array 3200 Controller. Q. How many Smart Array 3200 Controllers can I install in my system, and how many internal and external drives? A. The maximum number of Smart Array 3200 controllers that you can install in your system depends on your server and several other factors specific to your configuration. Generally, it will be the number of PCI slots not used for other peripherals.
J-2 Questions and Answers Q. I have several hard drives in my server and in the Compaq ProLiant Storage System. What SCSI IDs do I assign for these drives? A. Each hard drive must have a unique SCSI ID for each controller port. If your drives are installed in a Compaq ProLiant Server, a Rack-Mountable Compaq ProLiant Server, a Compaq ProLiant Storage System, or a RackMountable Compaq ProLiant Storage System, the SCSI IDs are automatically set according to the bay in which the drives are installed.
J-3 Q. I ordered my server with a pre-installed Smart Array 3200 Controller. Will the server ship with the SCSI cable that I will need to connect to my Compaq ProLiant Storage System? A. No, you will not receive the external SCSI cable with your server. However, the required cable is supplied with Compaq ProLiant Storage systems. Q. I do not have any hard drives in my server, but I am connecting it to a Compaq ProLiant Storage System which has several hard drives. Which SCSI port do I use? A.
J-4 Questions and Answers Q. What must I do if I do not understand the POST error message referring to the Smart Array 3200 Controller? A. First, copy down the POST error message for later reference.
