Chapter 1

Controller Features

The Compaq Integrated Smart Array Controller is a dual-channel, 32-bit PCI controller supporting RAID technology. It also supports Wide Ultra2 SCSI technology for faster data transfer rates and is backward compatible with Wide-Ultra SCSI-3 devices. The Integrated Smart Array Controller supports SCSI drives either through the external Wide-SCSI connector or the internal 68-pin Wide-SCSI connector, with a maximum of two supported channels. Configuring the server to use two separate SCSI ports provides maximum internal and external drive support without having to commit the resources of an expansion slot.

Standard Features

Features of the Compaq Integrated Smart Array Controller include:

■ Support for RAID 0, RAID 1, RAID 0+1, and RAID 5

■ Support for Wide Ultra2 SCSI technology and an improved data transfer

rate maximum of 80 MB/s

■ Backward compatible with Wide-Ultra SCSI-3 hard drives

■ Support for offline drive and array movement

■ Dual Wide Ultra2 SCSI channels supporting up to 15 drives on each

channel

■ Performance monitoring with Compaq Insight Manager

■ Option ROM Configuration for Arrays Utility

NOTE: If higher performance, higher availability, or higher capacity is required, arrays can be moved from the Integrated Smart Array Controller to a higher performance array controller without requiring a backup-and-restore procedure, but only if relative drive order is maintained. If relative drive order is changed, or if no data backup exists, perform a full backup before moving any array to another controller.

Controller Interface

The Integrated Smart Array Controller server interface is a Peripheral Component Interface (PCI) bus. The PCI bus is a high-performance, 32-bit bus with multiplexed address and data lines. It includes a parity signal and provides a high-speed path (up to 132 MB/s) between the system board and the array controller. The Integrated Smart Array Controller is a PCI Bus Master device and conforms to PCI Local Bus Specification, Revision 2.2.

Figure 1-1. Integrated Smart Array Controller

Drive Array Technology

Drive array technology distributes data across a series of hard drives to unite physical drives into one or more logical drives. Distributing data allows concurrent access to data from multiple drives in the array, yielding faster input/output rates than nonarrayed drives. Each logical drive in the array may be set to a different fault-tolerant configuration and the Integrated Smart Array Controller manages the drive array independent of the host processor.

Controller Features 1-3

The Compaq Array Configuration Utility found on the SmartStart and Support Software CD guides you through configuring the hardware in the way that best suits your needs.

Refer to the material in Appendix B for general information about drive arrays. Chapter 4 contains information about configuring your Integrated Smart Array Controller with Option ROM Configuration for Arrays utility, and Chapter 6 contains information about configuring hard drives and drive arrays with the Compaq Array Configuration Utility.

1-4 Compaq Integrated Smart Array Controller User Guide

Fault Tolerance

Fault tolerance relies on various methods for protecting data from loss in the event of a hardware failure somewhere in the storage system. Each method has its advantages, so choosing one requires careful planning for your particular requirements.

Fault-tolerance methods supported by the Integrated Smart Array Controller and the Compaq Array Configuration Utility include:

■ Distributed data guarding (RAID 5)

■ Drive mirroring (RAID 1)

■ Drive striping and mirroring (RAID 0+1)

■ No-fault tolerance (RAID 0)

■ Further data protection achieved by assigning an online spare to any

RAID 0+1, RAID 1, or RAID 5 configuration

See Appendix B for more information on fault-tolerance methods supported by the Integrated Smart Array Controller. Chapter 6, “Compaq Array Configuration Utility,” contains information on configuring your system for each of the fault-tolerance methods.

Drive Movement

An array of drives can be moved from one system to another as long as the relative order of the drives is maintained. However, when the relative order of the drives is changed, or if a new array controller is installed or reconfigured, all data stored on the drives are affected. For more information, refer to Chapter 6 in this guide.

Read-Cache Memory

The Integrated Smart Array Controller has 16 MB of total memory, with 8 MB dedicated for read-ahead cache.

Expanding and Extending Capacity

The Compaq Array Configuration Utility (ACU) makes changing your storage configuration simple, even in fault-tolerant configurations, without requiring a data backup-and-restore cycle. If you are using Microsoft Windows NT or Novell NetWare operating systems with hot-plug drives, storage expansion or extension can be performed online without shutting down the server or exiting the operating system.

The Compaq ACU supports two important utilities:

■ Capacity expansion–Adding capacity and creating new drives

■ Capacity extension–Enlarging existing logical drives

Online RAID Level and Stripe Size Migration

The Array Configuration Utility allows you to reconfigure a currently configured logical drive for a new fault-tolerance (RAID) level or move an existing logical drive’s stripe size to a new stripe size online without disruption to system operations and without loss of data. For more information about online RAID level and stripe size migration, refer to Chapter 6.

Controller Features 1-5

Wide Ultra2 SCSI Technology

The Integrated Smart Array Controller uses Wide Ultra2 SCSI technology for improved performance. Wide Ultra2 SCSI technology uses Low Voltage Differential (LVD) signaling to allow maximum burst rates on the Ultra2 SCSI bus of up to 80 MB/s. LVD signaling doubles the maximum burst rates available in Wide-Ultra SCSI-3 devices.

NOTE: The maximum burst rate of up to 80 MB/s provided by Wide Ultra2 SCSI (LVD) signaling is achieved only when the array contains Wide Ultra2 SCSI (LVD) devices exclusively.

Wide Ultra2 SCSI Compatibility

The Integrated Smart Array Controller is compatible with your existing SCSI devices. Wide Ultra2 SCSI works with devices that respond at transfer rates of up to 80 MB/s. Connected peripherals are limited to response times no faster than the transfer rate of the slowest device in the array.

1-6 Compaq Integrated Smart Array Controller User Guide

Wide-Ultra SCSI-3 Compatibility

In addition to using Wide Ultra2 SCSI technology, the Integrated Smart Array Controller complies with ANSI SCSI-3 standards and can support 16-bit Wide-Ultra SCSI-3 devices.

If the server remains unopened, it is not necessary to disconnect power and peripheral cables when you install an external SCSI connection.

Consult the user documentation provided with your storage system for exact cabling instructions and warnings.

IMPORTANT: Before connecting an external SCSI device to the external SCSI connector on the rear panel of the server, disconnect all devices from the internal SCSI port of the same channel, including the terminated SCSI cable. See your server documentation for specific cabling guidelines.

Connecting SCSI Cables

Optional mass storage SCSI devices such as Compaq ProLiant Storage Systems can be connected to the server with the external SCSI connector on the back of the unit. To connect your server to an external storage device, refer to the installation documentation provided with the external storage device and your server.

External Cabling 2-3

Use the following general procedure to connect your server to a mass storage SCSI device:

1. Place the server in Standby mode and disconnect the AC cords.

2. Remove the access panel.

3. Disconnect all devices, including the terminated SCSI cables (if any) from the internal SCSI port that is located on the same SCSI channel as the external SCSI port. (To remove the cable, see your server installation documentation on SCSI channel configuration procedures.)

4. Replace the access panel.

5. Use the cable provided with your storage system to attach the external SCSI connector (on the rear panel of the server) to the external SCSI connector (on the rear panel of the storage system).

The illustration below shows a typical configuration for a tower-to-tower external SCSI connection to a storage system.

Figure 2-1. Connecting a tower model server to a tower model storage device

CAUTION: Failure to connect external drives to the correct port or controller will result in loss of data.

Refer to Chapter 4, “Option ROM Configuration for Arrays Utility,” for detailed instructions on configuring the Integrated Smart Array Controller.

Chapter 3

Updating Firmware

The ROMs on all Compaq servers and most Compaq options can be updated easily by flashing the ROM. To flash a ROM, Compaq ROMPaq replaces the existing contents of the ROM with an updated version stored in a disk file. This method is a convenient way to distribute new firmware and to keep Compaq products up-to-date with the latest capabilities.

There are two ROMPaq utilities:

■ System ROMPaq

Update the system ROM in all Compaq servers supporting Flash ROM. Use System ROMPaq when you install a new Integrated Smart Array Controller in a Compaq server to be sure that the server utilizes the full range of capabilities available from the Integrated Smart Array Controller.

■ Options ROMPaq

Update the onboard ROM on all Compaq options supporting Flash ROM. Use Option ROMPaq when new versions of the Integrated Smart Array Controller firmware or SCSI drive firmware become available to take advantage of expanded capabilities.

IMPORTANT: Before you install the new Integrated Smart Array Controller in your server, update the system firmware by running the System ROMPaq utility. This process ensures that you have the latest ROM on your system.

Use the instructions in the following section to create diskettes with the latest version of System ROMPaq from the Compaq SmartStart and Support Software CD.

3-2 Compaq Integrated Smart Array Controller User Guide

ROMPaq Diskettes

Optimizing Array Controller Performance

To increase the performance of your disk subsystems under Novell NetWare versions 3.2, 4.2, and 5.0, perform the following steps before installing 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 NetWare INSTALL.NLM.The fault-tolerance capabilities of the Integrated Smart Array Controller provide performance improvements and automatic data recovery features.

■ Novell recommends that you create volumes with a 64-kb block size and

that you use the Block Sub-Allocation feature of Novell NetWare. Using a large block size decreases the amount of RAM required to mount the volume, while Block Sub-Allocation allows NetWare to allocate disk space more efficiently.

■ Linear memory configuration provides the best performance in a

Novell NetWare environment. When you use the Compaq System Configuration Utility to configure your server with NetWare, the memory options default to linear memory. To verify the setting, run the Compaq System Configuration Utility and view the Compaq Memory settings. Make sure that the linear option is selected under the Base Memory option.

5-22 Compaq Integrated Smart Array Controller User Guide

Controller Ordering

Two factors determine controller ordering in a system operating in an IBM OS/2 environment:

■ The order of ADD drivers specified in the CONFIG.SYS file determines

the order of types of controllers relative to other types of controllers.

A single ADD driver groups all of the controllers in its array together. Among a group of ADD drivers, the first ADD driver to appear in the CONFIG.SYS file has its controllers ordered first, the second ADD driver has its controllers ordered after the first driver controller, and so on.

Only the order shown in CONFIG.SYS affects the order. The slot in which the controller is installed does not affect the loading order.

■ Each ADD driver developed by Compaq orders its controllers in

ascending order based on the controller order assigned by the Compaq System Configuration Utility.

Use the following rules to ensure proper controller functioning and ordered interaction with other storage controllers in the system.

NOTE: The Compaq System Configuration Utility does not automatically enforce the recommended array configuration rules. Follow these rules carefully when you manually configure the system.

■ Compaq array controllers should be stored in consecutive order as a

group.

■ When you boot from the Compaq Integrated Smart Array Controller, the

statement BASEDEV = CPQARRAY.ADD must be present in CONFIG.SYS.

Partitioning

Observe the following limitations for IBM OS/2 on any computer system:

■ The maximum allowed partition size on FAT is 2 GB (2048 MB).

■ It is recommended that you do not exceed 8 GB for an HPFS boot

partition. If you exceed this size, the disk may run out of working room for the OS/2 system files and prevent the ROM from loading system files on start up.

■ This driver has been tested with HPFS partition sizes of up to 40 GB.

Do not create partitions exceeding 40 GB on any of the RAID volumes in an OS/2 environment.

The IBM OS/2 operating system may allow the creation of partitions beyond these specified boundaries, but you should adhere to the functional limits outlined above to ensure proper functionality.

Booting OS/2 from a Integrated Smart Array Controller Drive

This section describes additional information for starting OS/2 from a Compaq Integrated Smart Array Controller.

Installing the Operating System Drivers 5-23

The CPQARRAY.ADD driver must always be present when booting from the Integrated Smart Array Controller. If the controller is the primary disk controller, edit the CONFIG.SYS file to ensure that the first BASEDEV entry present is:

BASEDEV=CPQARRAY.ADD

This ordering guarantees that the CPQARRAY.ADD driver is the first ADD driver loaded and that the operating system assigns the first hard drive on the Integrated Smart Array Controller as the boot drive. For example:

BASEDEV=CPQARRAY.ADD

BASEDEV=CPQ53CX.ADD

If OS/2 boots from another controller, order the other controller first:

BASEDEV=AMSI02.ADD

BASEDEV=CPQARRAY.ADD

5-24 Compaq Integrated Smart Array Controller User Guide

Command Line Switches

There are several command line switches available for modifying the standard behavior of the Compaq ADD driver. The syntax for command line switches is:

■ /V

The Verbose Mode command line switch is a standard command line switch that instructs the driver to print information to the screen as it loads. The screen displays the current driver name and version number along with information about associated adapters and drives. Adapter information includes IRQ assignment, slot number, and configuration order number. Drive information includes physical drive count, logical drive count, and geometry information for each logical drive.

Verbose Mode command line may be written as:

BASEDEV=CPQARRAY.ADD /V

■ /A:[adapter index] [unit parameters]

This is a standard command line switch that instructs the driver to modify its behavior toward adapters.

The [adapter index] is the number that identifies a controller. The index is based on ‘0’ for the lowest controller order number associated with the adapter controlled by this ADD. The index number is incremented by one for each controller in the system as you move up the controller configuration order.

The table below shows a system with three adapters controlled by the CPQARRAY.ADD. The lowest configured adapter is the secondary controller.

Table 5-1

Controller Order and Adapter Index

Controller Order Adapter Index

[unit parameters] This ADD only supports the /I parameter containing the command to ignore a controller.

Installing the Operating System Drivers 5-25

/I Ignore

■

The Ignore command line instructs the controller to ignore the specified adapter, bypass controlling the adapter with the specified drive, or prevent the ADD driver from recognizing the specified adapter. Use this command to allow another driver to control the specified adapter.

CAUTION: Do not use this command line to ignore the primary, or boot, controller. If the boot controller is ignored, your server will not start.

Ignore command line example:

The following statement prevents the ADD driver from claiming adapter 2:

BASEDEV=CPQARRAY.ADD /A:2 /I

This example applies when you are running NetWare on your OS/2 2.x system and you want a NetWare NLM to control adapter 2 instead of configuring the ADD driver to control adapter 2.

Controller Settings Screen

The Controller Settings screen contains three configuration elements:

■ Operating System

■ Rebuild Priority

■ Accelerator Ratio

If you have installed and configured your operating system with SmartStart or manufacturer software, the current operating system is shown in the Operating System frame. Use the pull-down menu to load a different operating system.

Select your rebuild priority with the High, Medium, and Low buttons. Rebuild Priority selections have no impact on an idle system but will affect performance on a busy system.

The Rebuild Priority affects the amount of time the controller spends rebuilding data after a failed drive has been replaced. Select High if rebuilding data should take precedence over handling requests from the operating system. Select Low if the controller should rebuild data only when it is idle.

The Accelerator Ratio frame displays the amount of read-and-write cache available on the controller. The Integrated Smart Array Controller contains read cache space only. The ratio shown will always be 100% read to 0% write.

Figure 6-8. Controller Settings screen

Compaq Array Configuration Utility 6-11

Create Drive Array Screen

In the Create Drive Array screen, all available drives attached to the selected controller are listed in the left window and drives assigned to the current array appear in the right window. A port number and SCSI ID identify each drive.

To create an array, select the logical drives from the drive frame to use in the array and move them into the array frame by selecting the Assign Drive to Array button in the center of the screen. You can also select a drive and drag it to the array window. To assign a spare, select the drive to be the spare and then select the Assign Spare to Array button at the bottom of the screen.

Always group physical drives of the same size together. If you mix drive sizes, the Integrated Smart Array Controller treats all the drives as the same size as the smallest drive in the array, which results in wasted capacity in the larger drives.

Figure 6-9. Create Drive Array screen

6-12 Compaq Integrated Smart Array Controller User Guide

Create Logical Drive Screen

From the Create Logical Drive screen, you can select the fault-tolerance method, enable or disable the array accelerator, set the logical drive size, and set the stripe size.

The Integrated Smart Array Controller supports four fault-tolerance levels:

■ RAID 5

■ RAID 1

■ RAID 0+1

■ RAID 0

The Fault Tolerance frame allows you to select the appropriate RAID level.

Figure 6-10. Create Logical Drive screen

The Logical Drive Size area shows a scale marked with the amount of drive capacity available for the logical drive selected from the main configuration screen. The utility does not allow you to create a logical drive larger than the maximum supported by the operating system.

Compaq Array Configuration Utility 6-13

The purple (left) band on the scale indicates the fraction of the total that is available for data. The striped red (right) band indicates the fraction required for storing the parity or mirrored information depending on the fault-tolerance method used. The red (right) band is only needed for RAID 1, RAID 0+1, or RAID 5.

This area displays the maximum-sized logical drive that can be created for your drive array. You can reduce this amount if you want to create more than one logical drive on the array. To reduce the size, type the number in or drag the pointer to the left. Fine-tune the size with the arrow buttons to the left of the scale.

Array Accelerator Frame

The Integrated Smart Array Controller offers an 8-MB read cache option. The Array Accelerator frame allows you to disable this function.

Figure 6-11. Array Accelerator frame

Stripe Size

Stripe size refers to the amount of data stored on each physical drive in one stripe of a logical drive. Each RAID level has a default value plus a range of supported sizes. The default values shown in the following table provide optimum performance for that RAID level in many applications. However, your application may benefit from setting the stripe size to a different value.

To select a stripe size other than the default, select the down arrow next to the current stripe size and select from the sizes available.

6-14 Compaq Integrated Smart Array Controller User Guide

Stripe Size Fault Tolerance

Fault-Tolerance Level Default (KB) Valid Stripe Sizes (KB)

RAID 5 16 8, 16, 32, 64*

* RAID 5 does not support stripe sizes larger than 64KB per drive.

Online RAID Level and Stripe Size Migration

To change the RAID level and stripe size without loss of data or system disruption, use the Online RAID Level and Stripe Size Migration screen. From this screen you can reconfigure a currently configured logical drive to a new fault-tolerance (RAID) level or a new stripe size.

Novell NetWare Online Array Configuration Utility

Table 6-1

The Novell 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 Integrated Smart Array Controller. This utility indicates drive failure, expansion, or waiting for expansion or rebuild (queued). Before loading CPQONLIN.NLM, you must load the appropriate device

CPQARRAY.HAM. CPQONLIN.NLM is located in the ONLINE

driver directory of Novell SSD Disk 4. See driver installation information in the NetWare section of Chapter 5.

Autoconfiguration

If no logical drives are configured, a CPQONLIN autoconfiguration wizard, shown in the following figure, appears and prompts you to select faulttolerance information. CPQONLIN then configures arrays optimally for the selected fault tolerance.

Compaq Array Configuration Utility 6-15

Figure 6-12. NetWare autoconfiguration wizard using RAID 1 fault tolerance

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 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. The figure below shows the main configuration screen with the controller highlighted on the left side of the screen and controller options on the right side of the screen.

6-16 Compaq Integrated Smart Array Controller User Guide

Use online help for instructions to complete configurations. The following sections discuss CPQONLIN functions.

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 screen and select the Controller Settings option listed below Controller Options.

Compaq Array Configuration Utility 6-17

Figure 6-14. NetWare Controller Settings screen

NOTE: The figures in this section represent typical NetWare screen displays. Different versions of the software may present slightly different server displays.

Drive Rebuild

Drive rebuild is required after a physical drive fails and is replaced. Only logical drives configured for a fault-tolerance level (RAID 5, RAID 1, RAID 0+1, or RAID 0) on the array with the failed physical drive can be rebuilt.

6-18 Compaq Integrated Smart Array Controller User Guide

Priority Settings

To set the drive rebuild priority, highlight the Integrated Smart Array Controller in Controller Options frame and select Controller Settings. If you choose low priority for a drive rebuild, drive rebuilding takes place when the drive is idle. If you choose high priority, drive rebuilding takes place while the drive is active, at the expense of normal I/O operations. Choosing high priority for drive rebuilding protects the array, but the array is vulnerable to additional drive failures while a drive is both in operation and being rebuilt.

Accelerator Ratio

The Integrated Smart Array Controller onboard cache only performs read-ahead caching. Therefore, the ratio is always 100% read to 0% write. This read cache option can be disabled in the Array Accelerator frame on the Create Logical Drive screen.

Expand an Array

Overall server performance may be slightly degraded during an array expansion procedure. In most cases, degradation can be offset with additional physical drives.

■ To further minimize performance degradation, perform the capacity

expansion process during periods of low server use. If you must expand during peak periods, the Array Configuration Utility for NetWare allows you to set the priority of the expansion. Setting a low priority affects performance the least, but it takes longer for the new space to become available.

■ For expansion purposes, avoid using drives that have a greater capacity

than the smallest drive in the array. Adding larger drives wastes space because only the space that is equal to the smallest drive size can be used.

Add or Configure Spare Drives

When adding a spare drive to an array, you must have an unassigned drive or a drive already assigned as a spare on another array. You can assign a single spare to as many arrays as you want, or assign separate spares. When you select Assign Spare Drive, only drives that qualify will appear. For example, only those spares that are large enough will appear. If drives that you expect to see do not appear, switch to the physical drive view and check the size of the drives. The spare must be as large as the smallest drive in the array.

Compaq Array Configuration Utility 6-19

Online RAID and Stripe Migration

Using CPQONLIN, you can modify both the RAID level and stripe size of an existing logical drive while online. To migrate a drive, select the drive setting option under the logical drive menu for the drive you wish to modify. Select the new RAID level and/or stripe size from the choices presented to you. If the new settings are valid, the migration begins when you save your changes.

Failed Drives or Interim Recovery Mode

If a drive fails and hardware fault tolerance is enabled, system operations continue. Replace the drive as soon as possible. To recover a drive and use the failed drive in the interim, select a logical drive and press F3 to monitor the status of drive recovery, as shown in the figure below.

Figure 6-15. Logical Drive Information screen

■ Interim Recovery

The logical drive is operating, but a failed drive has not been replaced. Replace the failed drive as soon as possible.

■ Ready for Recovery

The logical drives are queued for recovery. This status is displayed when another logical drive is already rebuilding or expanding.

6-20 Compaq Integrated Smart Array Controller User Guide

Rebuilding

■

The array is operating and rebuilding a replacement drive or an online spare, if one was assigned.

■ Logical Drive Failed

If you have one or more logical drives in an array that are not protected by fault tolerance, the data on those logical drives are lost. The Array Configuration Utility status window shows the logical drives as Failed. After drive replacement, fault-tolerant logical drives rebuild and the logical drives that were not protected become available for data (the devices are reactivated automatically). After drive recovery and replacement is complete for the whole array, restore lost data from your backup data set.

If you do not replace the failed drive, the Array Configuration Utility requires you to delete the affected logical drives.

CAUTION: Deleting failed logical drives results in a loss of all data stored on the drive.

NOTE: Drive failure can occur on drives protected by fault tolerance if two or more physical drives fail concurrently.

Some status indicators activate without pressing F3. For example, on the Main Configuration menu, a FAILED status message appears beside the failed logical drive. EXPANDING and REBUILDING messages appear next to the array in which the corresponding activity occurs.

Handling Disk Drive Failures

If you configured your Integrated Smart Array Controller with hardware fault tolerance, complete the following steps after a physical disk drive failure:

1. Determine which physical drive failed. On hot-plug drives in a ProLiant server or storage system, an amber Drive Failure LED on each drive tray indicates failure.

2. If the unit containing the failed drive does not support hot-plug drives, perform a normal system shutdown.

Compaq Array Configuration Utility 6-21

3. Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug drives, 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. The online LED blinks, indicating that the controller recognized the drive replacement and began the recovery process.

4. Ensure that server power is on. If you shut down the server in Step 2, power the server back up.

5. The Integrated Smart Array Controller firmware reconstructs the information on the new drive based on information from the remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives, the online indicator blinks. When drive rebuild is complete, the online indicator stays lighted.

6. NetWare cannot detect a physical drive failure when using hardware-based fault tolerance; NetWare determines that the data is still valid and accessible during the rebuilding process. However, the driver does know that a physical drive has failed. A message will be printed on the console notifying the user a physical drive is in a degraded state. CPQONLIN will also show the drive has failed.

Optimizing Array Controller Performance for Novell Systems

To improve system performance, keep these tips in mind before creating NetWare volumes or partitions:

■ If you selected a fault-tolerance option during configuration, such as

mirroring or distributed data guarding, do not select mirroring while using INSTALL.NLM or NWCONFIG.NLM. The fault-tolerance capabilities of the Integrated Smart Array Controller already provide performance improvements and automatic data recovery features.

■ Novell recommends that you create volumes with a 64-KB block size

and that you use the Block Sub-Allocation feature of NetWare. The large block size decreases the amount of RAM required to mount the volume, and suballocation allows NetWare to allocate disk space more efficiently.

■ Using linear memory provides the best drive performance in a NetWare

environment. When you use the Compaq System Configuration Utility to configure your server with NetWare, the memory options default so that linear memory is used. To verify the setting, run the Compaq System Configuration Utility and view the memory settings. Make sure that a linear option is selected under the Base Memory option.

Configuration Procedures

Creating a New Array

This section provides instructions for creating or modifying new arrays after you have installed your operating system. If you are configuring a new array, the configuration wizard leads you through the process. If you want to bypass the wizard, use the following procedures to create your array.

Creating a new array involves the following general steps:

■ Choosing a controller for the array

■ Grouping physical drives of the same size into an array

■ Subdividing the array into one or more logical drives

The following example illustrates how to use the Array Configuration Utility to create a new array.

For this example, make the following assumptions:

■ Array A contains at least one physical drive that has been configured as

a logical drive and contains the operating system.

CAUTION: Do not modify the logical drive that contains the operating system. Modifying this drive can result in loss of data.

■ Four 9.1-GB drives and two 4.3-GB drives are connected to the

Integrated Smart Array Controller. The operating system is not installed on any of these drives.

■ Two new arrays will be configured. Array B consists of three 9.1-GB

drives with the fourth 9.1-GB drive used as a spare. Array C contains the two 4.3-GB drives.

■ The fault-tolerance method for all logical drives on Array B is RAID 5,

Distributed Data Guarding. The fault-tolerance method for all logical drives on Array C is RAID 1, Drive Mirroring.

Choosing a Controller for the Array

Start the Array Configuration Utility from the SmartStart and Support Software CD. From the Main Configuration Screen, select the Controller Selection frame. You can also select Controller/Select from the main menu.

1. Select one of the controllers listed in the Controller Selection frame.

Figure 6-16. Controller Selection frame

2. Select the Settings button shown below.

Figure 6-17. Controller buttons

3. At the Controller Settings screen, select your operating system.

Compaq Array Configuration Utility 6-23

Figure 6-18. Controller Settings screen

4. Select the Done button to save settings and exit.

6-24 Compaq Integrated Smart Array Controller User Guide

Grouping Physical Drives of the Same Size into an Array

This procedure creates two new arrays: Array B and Array C. Array A contains the operating system and will not be used or modified.

1. In the Controller Selection frame, select the Smart Array Controller, Embedded Slot.

2. Select the Create Array button. The Create Drive Array screen is displayed.

Figure 6-19. Create Drive Array screen

3. Select the four 9.1-GB drives you want to use in array B from the drives listed in the Existing Drives frame.

NOTE: Always group physical drives of the same size. The Integrated Smart Array Controller treats all the drives as the same size as the smallest drive in the same array. If you mix drive sizes, the capacity of the largest drive is wasted.

For this example select the following drives:

Port 2:SCSI ID 0 Port 2:SCSI ID 1 Port 2:SCSI ID 2

Compaq Array Configuration Utility 6-25

4. Select the Assign Drive(s) to Array button.

5. Select the drive at Port 2:SCSI ID 3 and select the Assign Spare to

Array button. The right side of the Create Array screen should now look similar to the figure below.

Figure 6-20. Example Array B

NOTE: The same spare drive may be assigned to multiple arrays. However, spare drives must have the same or greater capacity as the drives in the array.

6-26 Compaq Integrated Smart Array Controller User Guide

6. Select the Done button to return to the main configuration screen. The Logical Configuration View frame should now look similar to the following figure.

Figure 6-21. Logical Configuration View frame with one configured array

7. Select your controller from the pull-down menu in the Controller Selection frame.

8. Select the Create Array button to create Array C.

9. Assign both 4.3-GB drives to the array.

10. Select the Done button to save the array and exit.

Creating Logical Drives Across Physical Drives

When creating a logical drive, you can select a fault-tolerance (RAID level) option and provide information regarding the drive size and array accelerator.

1. Select Array B or the Unused Space icon under Array B in the Logical Configuration View.

2. Select the Create Logical Drive button. A screen similar to the following figure displays.

Compaq Array Configuration Utility 6-27

Figure 6-22. Create Logical Drive screen

3. In the Fault Tolerance frame, select the Distributed Data Guarding (RAID 5) option.

4. The Logical Drive Size area shows a graphical representation of the storage capacity available. To create a single logical drive across this array, accept the default values. Refer to the section titled “Create Logical Drive Screen” later in this chapter for a detailed description of this procedure.

6-28 Compaq Integrated Smart Array Controller User Guide

NOTE: Because the size of the logical drive depends on the number and size of drives used in the array, there is no right or wrong logical drive size.

5. Select the Done button.

6. Select Array C or the Unused spare icon under Array C in the Logical Configuration View.

7. Repeat Steps 2 through 5 to create a single logical drive across Array C, this time selecting the RAID 1 fault-tolerance option.

8. The Logical Configuration View screen appears as shown in the figure below.

Figure 6-23. Logical Configuration View window showing three arrays with different RAID assignments

9. At the main screen, pull down the Controller menu, then select Save Configuration. This saves the new settings for logical drive 2 and logical drive 3.

Expanding Capacity

Expanding array capacity involves adding storage capacity to an array that has already been configured without disturbing the existing data by adding new physical drives to the array.

When you run the Array Configuration Utility, the program checks the drive hardware and configuration. If the Array Configuration Utility discovers a physical drive that is not used, the configuration wizard leads you through the steps for adding the drive to the array.

Expanding Array Capacity

To expand your array manually:

1. Install the new physical drives.

NOTE: Always group physical drives of the same size. If you mix drive sizes, the capacity of the larger drives is wasted.

2. Assign the new physical drives to an existing array. Existing logical drives will automatically expand across the physical drives, including the newly added ones.

Compaq Array Configuration Utility 6-29

6-30 Compaq Integrated Smart Array Controller User Guide

3. Create a new logical drive to use the extra space on the expanded array. For this example, assume a configuration similar to the previous example, except that the fourth 9.1-GB drive is added later and Array B does not have a spare. Expand Array B to include the fourth drive. In the following figure, a single 9.1-GB drive is shown as unassigned in the main configuration screen.

Figure 6-24. Logical Configuration View screen

To expand the capacity of Array B and create logical drive 2:

1. Select Array B.

2. Select the Expand button.

3. Select the unassigned 9.1-GB drive.

4. Select the Assign Drives to Array button.

Compaq Array Configuration Utility 6-31

5. Select the Next button at the bottom of the screen to advance to the Create Logical Drives screen, as shown below.

Figure 6-25. Create Logical Drives screen

6. Select the Create Logical Drive button.

7. Set the fault tolerance, array accelerator, stripe size, and size for the new logical drive.

8. Select the Done button to return to the main configuration screen.

9. At the main screen, pull down the Controller menu, the select Save Configuration from the menu bar. This saves the new settings and starts the capacity expansion process.

NOTE: The new logical drive will not be accessible until the capacity expansion process has been completed on the existing logical drive.

6-32 Compaq Integrated Smart Array Controller User Guide

Capacity Extension

Logical drive extension allows you to increase the size of existing logical drives without disturbing the data on those logical drives. If an existing logical drive is full of data, you can extend the logical drive when there is free space on the array. If there is no free space on the array, you can add drives to the array and proceed to extend the logical drive.

IMPORTANT: Logical drive extension is not supported by all operating systems. You can only extend logical drives that are used with an operating system supporting capacity extension.

Operating Systems

The following operating systems support logical drive extension:

■ Microsoft Windows NT 4.0 and Windows 2000

■ Novell NetWare 5.0

■ IBM OS/2 Warp 4.0, WarpConnect, WarpServer, WarpServer

(Advanced), and WarpServer SMP

■ SCO OpenServer 5, UnixWare 7, and UnixWare 2

If your operating system is not listed, check your operating system documentation or contact your operating system vendor before extending logical drives.
