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. The readahead cache uses a multi-threaded algorithm to predict the next likely read
operation for the array. This data is then read into the array accelerator from the
drives. When the Smart Array 3200 Controller receives a read request for the
cached data, the data can be brought into the system at memory speeds and
avoid the latency of a disk access. The array accelerator feature can be disabled
manually with software or by the Automatic Performance Tuning Feature.
NOTE: The Smart Array 3200 Controller is not operable without the array
accelerator board attached.
The array accelerator’s ECC memory provides a high level of data integrity.
ECC memory detects and corrects hard and soft memory errors without
affecting performance.
The array accelerator is backed up with onboard rechargeable batteries so that
the data temporarily held (cached) there is safe during equipment failure or
power outages. This is particularly important for data that has been cached by a
posted-write, but has not yet been written to the hard drives. The batteries
preserve data in the array accelerator for up to four days.
IMPORTANT: The rechargeable batteries on a new Smart Array 3200
Controller may be discharged when the board is first installed. During server
power-up with discharged array accelerator batteries, Power-On Self-Test
(POST) displays the code “1794,” indicating that the array accelerator is
disabled. This does not require action on your part. The array accelerator is
enabled automatically when the batteries are charged to 90 percent of their
capacity.
It can take up to 36 hours for the internal circuitry to fully charge the
batteries . During this time, the array accelerator will be disabled; the Smart
Array 3200 Controller will function properly, but without the performance
advantage of the array accelerator.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. If the
configuration information stored in the Array accelerator matches that stored on
the drives, any valid posted-write data being held in the cache will be written
automatically to the drives attached to the replacement array controller. Thus,
data being held in the array accelerator memory can be recovered despite failure
of the main Smart Array 3200 Controller board. Refer to Appendix F,
“Replacing the Array Accelerator,” for specific information.
Wide-Ultra2 SCSI Technology
The Smart Array 3200 Controller uses Wide-Ultra2 SCSI technology for
improved performance. Wide-Ultra2 SCSI uses Low-Voltage Differential
(LVD) signaling to enables maximum burst rates on the Wide-Ultra2 SCSI bus
of 80 MB/s, which doubles the maximum burst rate of the Wide-Ultra SCSI.
Wide-Ultra2 SCSI Benefits
1-5
The Wide-Ultra2 SCSI LVD technology provides these additional benefits:
■ 80 MB/sec maximum burst
■ Longer SCSI bus cable lengths
■ System configuration for up to 15 peripherals
Wide-Ultra2 SCSI Compatibility
Wide-Ultra2 SCSI is compatible with your existing installed SCSI base. The
Diff Sens circuit in the Wide-Ultra2 SCSI configures the drive operation and the
appropriate bus capability. Wide-Ultra2 SCSI will work with the oldest SCSI
designs. It is important to remember, however, that when using different SCSI
devices on the same SCSI bus, all peripherals on that bus will respond to the
earliest version SCSI specification. If an Ultra design is installed on an WideUltra2 SCSI (LVD) bus, all devices will respond at Ultra speeds.

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. The utility:
■ Provides a graphical representation of drive array configurations
■ Uses Wizards to help optimize your array configuration
■ Allows express or custom initial configuration
■ Allows online spare (hot spare) configuration
■ Supports RAID 0, 0+1, 1, 4, and 5 fault-tolerant configurationsAllows
separate fault-tolerance configuration on a logical drive basis
■ Allows user-selectable stripe-size
■ Allows online stripe size migration
■ Allows online RAID level migration (between any two RAID levels)
■ Allows online logical drive capacity extension
■ Enables easy online capacity expansion
■ Sets drive rebuild and capacity expansion priorities
Working with Drive Arrays
Drive array technology distributes data across a series of hard drives to unite
these physical drives into one or more higher-performance logical drives.
Distributing the data makes it possible to access data concurrently from multiple
drives in the array, yielding I/O rates faster than those of non-arrayed drives.
Each logical drive in the array can be set to a different fault-tolerant
configuration. The Smart Array 3200 Controller manages the drive array,
independent of the host processor.
There may be several ways to configure each set of hardware. The Array
Configuration Utility software helps configure the hardware to your needs.
Refer to Appendix E for more information on drive arrays. Refer to Chapter 5,
“Running the Array Configuration Utility,” for information on configuring your
drive arrays.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. The fault-tolerance
methods supported by the Smart Array 3200 Controller and the Array
Configuration Utility include:
■ Distributed data guarding: RAID 5
■ Data guarding: RAID 4
■ Drive mirroring: RAID 1 or RAID 0+1 (also called RAID 10)
■ No fault tolerance: RAID 0
Further data protection can be achieved by assigning an online spare to any
RAID 1, RAID 0+1, RAID 4, or RAID 5 configuration. Refer to Appendix E
for more information on fault-tolerance methods. Refer to Chapter 5 for
information on using the Array Configuration Utility to configure your system
for fault tolerance.
1-7
Expanding or Extending Capacity
Changing your storage configuration is easy using the Array Configuration Utility
and does not require a data backup and restore cycle, even in fault-tolerant
configurations. If you are using Microsoft Windows NT or Novell NetWare
operating systems with hot-pluggable drives, storage expansion or extension can
be performed online, without shutting down the server’s operating system.
Capacity expansion refers to adding capacity and creating new logical drives.
Capacity extension refers to increasing the size of an array by adding physical
drives and growing an existing drive without adding more logical drives. For more
information on storage expansion or extension, see “Running the Array
Configuration Utility,” in Chapter 5, and the section, “Adding Storage Capacity”
in Appendix E.

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.
Wide-Ultra2 SCSI
Wide-Ultra2 technology provides data transfer rates of up to 80 MB/sec at a
40-MHz bus rate. This combination allows higher throughput in many network
application environments than does Wide-Ultra SCSI-3.
Wide-Ultra SCSI-3
Wide-Ultra SCSI-3 technology provides SCSI data transfer rates of up to
40 MB/sec at a 20-MHz bus rate. This combination allows high throughput in
many network application environments, including resource sharing and
database servicing.
Fast-Wide SCSI-2 and Fast SCSI-2
Fast-Wide SCSI-2 provides two bytes of data at each bus transfer, providing a
maximum data rate of 20 MB/sec between SCSI devices while maintaining a
10-MHz bus rate.
Fast-Wide SCSI-2 controllers and devices communicate using Fast SCSI-2
protocol when required. Fast SCSI-2 drives are supported by the Smart Array
3200 Controller using the appropriate cable adapter.

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.
■ Drives may be Wide-Ultra2 SCSI, Wide-Ultra SCSI-3, Fast-Wide SCSI-2,
Fast SCSI-2, or a combination of the four in servers and storage systems that
support hot-pluggable drives.
■ Drives should not contain termination. Compaq servers and internal
cabling provide the required termination of the SCSI bus.
Table 2-1 shows the Compaq hard drives supported by the Smart Array 3200
Controller.

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. Server specifications are also available at the

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. This backup may also be used to return
to the original configuration, if necessary.
3. Add drives. If you are using a server or storage system that does not
support hot-pluggable drives, you will need to power-down the server or
storage system to add new drives. If you are using a server or storage
system that does support hot-pluggable drives, do not power-down the
system or take it off line. Simply plug the new drives into vacant bays.
4. Configure drive array. Refer to “Capacity Expansion” in Chapter 5 for
instructions on using the Compaq Array Configuration Utility to
reconfigure your drive array and make use of the added capacity.

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 fault-
tolerance 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. Proceed to Chapter 5, “Running the Array
Configuration Utility,” for information on reconfiguring your drive array
with the new Fault Tolerance (RAID Level). Your system automatically
redistributes the data according to the new Fault Tolerance (RAID
Level).
4. Restart the System or Restore data.
5. Copy the backed-up data into the same logical drive.

Changing the Stripe Size of an Array
General steps for changing the stripe size of an array:
1. Review. Refer to “User Selectable Stripe-Size” in Appendix E for
information on setting stripe size and the default values for given
RAID levels.
2. Back up data. Changing the stripe size may require destroying the data
on those logical drives. You must back up all data in the logical drives
where you will be changing the stripe size.
3. Change stripe size. Proceed to Chapter 5, “ Running the Array
Configuration Utility,” for information on reconfiguring your logical
drive with the new stripe size. In this case, a data backup is required.
4. Restart the system or Restore data. Copy the backed-up data into the
same logical drives, if necessary. Your system automatically
redistributes the data according to the new striping factor.

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.) Although data loss is not anticipated during
drive movement, Compaq recommends that you back up data before moving
drives. To move drives, the following conditions must be met:
■ System power is OFF (includes all system components).
■ The move will not result in more than 30 physical drives or 15 physical
drives per SCSI bus and/or 32 logical drives (volumes) connected to a
single controller.
■ No failed drives are identified. The array should be in its original
configuration with no active spare drives.
■ Capacity expansion is not running.
■ Controller firmware is the latest revision (recommended).
When the above conditions are met, follow these steps to move drives:
1. Power-down the System.
2. Move drives.
3. Power-up the system. A 1724 POST message should indicate that drive
positions were changed and the configuration was updated. 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.
4. Run the Array Configuration Utility to view the new drive configuration
(optional).

Moving Arrays
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. To move an array
to another controller, the conditions listed previously for moving drives and the
following additional restrictions must be met:
■ All drives in the array must be moved at the same time.
■ Positions of drives on the destination controller should not be changed at
the same time.
If any drives are missing or have failed, all data on the moved arrays could be
lost. To protect against data loss, data should be backed up before moving an
array. If you moved an array previously and plan to restore it to its original
controller, see the following section, “Restoring an Array to Its Original
Controller.”

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. Use System ROMPaq when installing a new
Smart Array 3200 Controller in a Compaq server to be sure
that the server can use all the capabilities of the Smart
Array 3200 Controller.
Options ROMPaq Updates the onboard ROM on all Compaq options that
support programming. Use Options ROMPaq when new
versions of the Smart Array 3200 Controller firmware or
SCSI drive firmware become available to take advantage of
expanded capabilities.
3-1
IMPORTANT: Before you install the new Smart Array 3200 Controller in
your server, you must run System ROMPaq to update the system firmware.
Use the instructions below to create diskettes with the latest version of
System ROMPaq from the Compaq SmartStart and Support Software CD
supplied with the Smart Array 3200 Controller.
ROMPaq Diskettes
The ROMPaq utility must be run from diskette(s). The latest version of
ROMPaq diskettes can be created from the Compaq SmartStart and Support
Software CD supplied in the Smart Array 3200 Controller option kit. Compaq
recommends that you use this version of ROMPaq initially; it is the latest one
that supports your new Smart Array 3200 Controller.

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. If you purchased your server with Smart Array 3200
Controller already installed, you do not need to run System ROMPaq at the time
of server installation.
CAUTION: If you are replacing an existing array controller, such
as the Compaq SMART Array Controller, with a Smart Array 3200
Controller, the system may not boot after hardware installation.
This occurs if the old array controller was the primary controller
containing the boot disk.
To avoid this problem when replacing an existing array controller
with a Smart Array 3200 Controller, run System ROMPaq before
you install the hardware. This ensures that the server recognizes
the Smart Array 3200 Controller and does not hang up on boot.

Chapter 5
Running the Array Configuration
Utility
This chapter provides instructions for using the Compaq Array Configuration
Utility and describes methods to configure your controller quickly and easily.
The Array Configuration Utility is located on the SmartStart and Support
Software CD.
The utility uses a graphic interface to help you configure the Smart Array 3200
Controller. You can use it to configure the Smart Array 3200 Controller
initially, to add additional disk drives to an existing configuration, or to
reconfigure an array controller.
The Array Configuration Utility is compatible with the operating systems
discussed in Chapter 6. It is an offline utility, except in servers running
Windows NT. An online utility for NetWare users is also described in this
chapter.
Write Caching
5-1
The physical drives attached to this controller may support a write cache. The
write cache policy of the controller can be enabled or disabled by choosing the
Advanced Features menu item from the Controller menu.
When the write cache is enabled for the controller and the configuration is
saved, write cache is enabled for each hard disk attached to the new controller.
When write cache is enabled for the controller, it automatically turns on the
write cache for each hot-plugged drive.
Not all physical drives have a reliable write cache. When SCSI bus resets or
device resets occur, an unreliable write cache can lose data. The Array
Configuration Utility treats drives with an unreliable write cache as though
those physical drives did not have a write cache.

Configuration Procedures
If you are configuring a new array, the configuration wizard leads you through
the process. You can, however, bypass the wizard and manually:
■ Create a new array
■ Expand the capacity of an array
■ Extend the capacity of a logical drive
■ Change online stripe-size migration
■ Change online RAID level migration
Use the procedures in the following sections to configure your array manually.
Create a New Array
Procedure—Creating a New Array
There are three general steps for creating a new array:
■ Step 1: Choose the Smart Array 3200 controller for the array.
5-5
■ Step 2: Group physical drives of the same size into an array.
■ Step 3: Create logical drives. (Divide the array into one or more logical
drives.)
Example—Creating a New Array
For this example, use the following assumptions:
■ Four 4.3-GB drives and two 9.1-GB drives are connected to the Smart
Array 3200 Controller.
■ There will be two arrays. Array A consists of three 4.3-GB drives with
the fourth 4.3-GB drive used as a spare. Array B consisting of two 9.1GB drives.
■ The fault-tolerance method for all logical drives on Array A is RAID 5,
Distributed Data Guarding. The fault-tolerance method for all logical
drives on Array B is RAID 1, Drive Mirroring.

Capacity Expansion
Capacity expansion involves adding storage capacity to an array that has already
been configured. If an existing array is nearly full of data, you can expand the
capacity without disturbing the existing data. The Smart Array 3200 Controller
capacity expansion feature allows the addition of a new physical drive(s) 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 being used, the configuration wizard leads you through
the steps for adding the drive.
Procedure—Expanding Array Capacity
To bypass the configuration wizard and manually expand your array:
1. Install the new physical drive(s).
2. Assign the new physical drive(s) to an existing array. Existing logical
drive(s) will automatically expand across the physical drives, including
the newly added one(s).
3. Create a new logical drive to use the extra space on the expanded array.
See the following example.

Controller Settings Screen
Use the Controller Settings screen to select the operating system and set the
Rebuild Priority, Expand Priority, and Accelerator Ratio. Rebuild and Expand
priority settings will not affect an idle system, but they will affect performance
on a busy system.
Figure 5-20. Controller Settings screen
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 Expand Priority affects when the controller moves data after you have
chosen to expand the capacity of an array. Select High if expanding the array
capacity should take precedence over handling requests from the operating
system. Select Low if the controller should expand the array capacity only when
it is idle.
The Accelerator Ratio determines the amount of memory allocated to the read
and write caches. Some applications may perform better with a larger write
cache; others may perform better with a larger read cache.

Create Drive Array Screen
In this screen, all available drives attached to the selected controller are
displayed on the left. Drives assigned to the current array appear on the right.
Each physical drive is identified by a port number and SCSI ID.
To create an array, select the drive or drives to be part of the array, then press
the Assign Drive(s) to Array (top) button. You can also select drives and drag
them to the array. To assign a spare, select the drive to be the spare, then click
the Assign Spare to Array (bottom) button.
Always group physical drives of the same size. If you mix drive sizes, the Smart
Array 3200 Controller treats all the drives as the same size as the smallest drive
in the array. This results in wasted capacity in the larger drives.
To increase performance, select drives from both ports and install the correct
drives on both ports before running the Array Configuration Utility.

Create Logical Drive Screen
In this screen, you can select the fault-tolerance method, enable the array
accelerator, set the logical drive size, and set the stripe size.
NOTE: Given the reliability of a particular generation of hard drive technology,
the probability of an array experiencing a drive failure increases with the
number of drives in an array. Compaq recommends the number of drives in an
array be limited to 15.
Figure 5-22. Create Logical Drive screen
The Logical Drive Size area includes a scale marked with the amount of drive
capacity available for a logical drive. The utility does not allow you to create a
logical drive larger than the maximum supported by the operating system.
The left side of the Logical Drive Size scale indicates the amount of space
available for data. The right side of the scale indicates the amount of space
required for storing parity or mirrored information, depending on the faulttolerance method. This is needed only for RAID 1, RAID 4, or RAID 5.

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.
Logical Drive Extension
Capacity extension refers to increasing the size of an array by adding physical
drives and growing an existing logical drive (without adding more logical
drives).
To extend the capacity of an existing logical drive offline:
■ Back up all data
■ Reconfigure the array
■ Restore the data
To extend the capacity online, the operating system on your server must support
a logical drive increasing in size. Use the Logical Drive Extension screen to
increase the size of an existing logical drive online and without data loss.

Stripe size refers to the amount of contiguous data stored on each physical drive
in a logical drive. Each RAID level has a default value (Table 5-1) plus a range
of supported sizes. The default values were determined to provide optimum
performance for that RAID level in many applications. However, your
application may benefit from setting the stripe size to a different value.

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.NLM, you must load
the appropriate device driverCPQARRAY.HAM. CPQONLIN.NLM is located
in the ONLINE directory of Novell SSD Disk 4. See driver installation
information in the NetWare section of Chapter 6.
Auto-Configuration
If no logical drives are configured, a CPQONLIN auto-configuration wizard
(Figure 5-23) appears and prompts you to select a fault-tolerance level.
CPQONLIN then configures arrays optimally for the selected fault tolerance.

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. Compaq SMART 3200 Controller settings screen
Drive Rebuild
Drive rebuild occurs after a physical drive fails and is replaced, or when a
physical drive fails in an array that has an online spare. Only logical drives
configured for fault tolerance (RAID 1, RAID 4, or RAID 5) on the array with
the failed physical drive will rebuild.
Priority Settings
To set the drive rebuild priority, highlight the Smart Array 3200 Controller and
select the Controller Settings. If you chose low priority for drive rebuilding (the
default), rebuild takes place only when the Smart Array 3200 Controller is not
busy handling normal I/O requests. Low priority has minimal effect on normal
I/O operations. With high priority, drive rebuilding occurs faster, at the expense
of normal I/O operations. Choosing high priority for drive rebuilding protects an
array, but the array is vulnerable to additional drive failures while a drive is
being rebuilt.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. This option can be
modified from the Controller Settings menu when the Array Accelerator is
installed.
Expand an Array
During an expand, performance may be slightly degraded. In most cases,
however, any potential degradation is offset by the addition of physical drives.
Some tips for expanding are:
■ Perform the expand 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 expand. Setting the priority
to LOW will affect performance the least, but it will take longer for the
new space to become available.
5-33
■ When expanding, you must add drives of at least the same capacity as
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 (TAB key), and check the size
of the drives. The spare must be as large as the smallest drive in the array.

Figure 5-26. Rebuilding logical drive screen
■ Interim Recovery: The logical drive is operating, but a failed drive has

■ Logical Drive Failed: If you have one or more logical drives that are not
protected by fault tolerance in an array, the data on these logical drives
will be lost. The Array Configuration Utility shows the logical drives as
FAILED. After drive replacement, any fault-tolerant logical drives
rebuild. The logical drives that were not protected (FAILED) become
available for data (the devices are reactivated automatically). If you have
a backup of the data, restore the data now.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. EXPANDING and REBUILDING will appear next to the array in which
the activity is occurring.
Handling Disk Drive Failures
If you configured your Smart Array 3200 Controller with hardware fault
tolerance, complete the following steps after a disk drive failure.
1. Determine which physical drive failed. On hot-pluggable drives in a
ProLiant server or storage system, this is indicated by an amber Drive
Failure LED on each drive tray.
2. If the unit containing the failed drive does not support hot-pluggable
drives, perform a normal system shutdown.
5-35
3. Remove the failed drive and replace it with a drive of the same capacity.
For hot-pluggable 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. Power-up the server, if applicable.
5. The Smart Array 3200 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 hotpluggable drives, the Online LED blinks. When drive rebuild is
complete, the Online LED is illuminated.
6. NetWare cannot detect a single physical drive failure when using
hardware-based fault tolerance NetWare considers the data to be is still
valid and accessible during the rebuilding process.

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. The fault tolerance
capabilities of the Smart Array 3200 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 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.
■ Use of linear memory provides the best performance in the 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 Compaq Memory settings. Make sure
that a linear option has been selected under the Base Memory option.
Using the Compaq Drive Array Optimization
Utility (CPQDAOPT)
Compaq recommends that you use the Compaq Drive Array Optimization
Utility (CPQDAOPT.NLM) to optimize the drive arrays on your server before
creating partitions. CPQDAOPT assists you in optimizing performance and can
increase drive array performance by 20 to 40 percent. CPQDAOPT provides a
formula specific to your configuration. Use this information as you create a
partition using INSTALL.NLM. If you installed NetWare using SmartStart, it is
not necessary to run this utility.

Using CPQDAOPT on NetWare Servers
NOTE: Back up existing data before applying new settings to data volumes.
1. Start your NetWare server.
NOTE: The following steps are meant as an example.
2. 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.
5-37
NOTE:
CLIB.NLM
must be v3.11c or later.
3. Be sure you load CPQDA386.DSK (version 3.10 or later).
4. When the Create NetWare Partition option appears during a new
NetWare installation, use the Alt+Esc key sequence to change to the
console prompt and load CLIB:
Load clib.nlm
5. Load CPQDAOPT.NLM from Novell SSD Disk 4:
Load A:\drv_arry\cpqdaopt
6. CPQDAOPT displays the registered disk devices it has located. Select
the device where you will create a partition by using the cursor keys.
Press Enter.
CPQDAOPT determines if it is possible to optimize the alignment of
data on the selected device. If so, it provides a formula to determine the
size of the Hot Fix Redirection Area you should select when creating this
partition. Note the formula: even, odd, and so on.
7. In some cases, it may not be possible to optimally align the data on the
partition by sizing the Hot Fix Redirection Area alone. CPQDAOPT may
instruct you to create a small DOS partition on the device. If so:
a. Exit NetWare before creating the partition.
b. Use the DOS FDISK utility to create the smallest DOS partition
allowed.
c. Start the server and load CPQDAOPT.NLM again.

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. After the volume is optimized, copy the CPQDAOPT.NLM to the
server’s SYSTEM partition so that it is easily accessible for future
optimizations. In the following example, F: is mapped to the server’s
SYSTEM partition. From a client logged into the server, type:
copy A:\drv_arry\cpqdaopt.nlm f:\system\cpqdaopt.nlm
If you have already created a partition on a device, use CPQDAOPT to
determine if the data is optimally aligned.
A may appear warning about changing the cache buffer size on your server. In
some cases, increasing the size of the cache buffers on a NetWare server may
slow I/O performance. If you must enlarge the cache buffer size and this takes
the partition out of optimal alignment, or, if CPQDAOPT indicates that the
existing partition on a device is not optimally aligned, you can still configure the
partition optimally:
1. Back up the data on your server to avoid data loss.
2. Use INSTALL.NLM Disk Options, Partition Tables, and Change Hot Fix
Option to change the size of the Hot Fix Redirection Area using the
formula provided by CPQDAOPT.
3. Create your volume(s).
4. Restore your data.

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.
If you did not use SmartStart 4.22 or later as part of your Smart Array 3200
Controller installation, you must manually update the Insight Agents. The
correct agents can be obtained from your local Compaq Reseller or authorized
Compaq Service Provider. Refer to the documentation included with Compaq
Insight Manager for the correct procedure for updating agents.
Installation of the Compaq Smart Array 3200 Controller is complete. Reboot the
server to begin using the array controller.
Software Drive Mirroring
with NetWare
NetWare recognizes each logical drive in an array as a separate physical drive.
If you mirror logical drives on the same array and a physical drive fails, both
logical drives in the mirrored pair will also fail and your data will be lost.
To avoid this, you must mirror logical drives on separate arrays. Use the
Compaq Array Configuration Utility for NetWare (CPQONLIN.NLM) on
Novell SSD Disk 1 to view the logical configuration for the Smart Array 3200
Controller. Record the logical drives and the arrays on which they reside. When
configuring NetWare for drive mirroring, select equally sized logical drives on
different arrays.
IMPORTANT: Do not use NetWare drive mirroring if you do not have at
least two arrays.

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.
Another advantage of hardware fault tolerance is that the controller is able to
perform a background surface analysis on the hard drives to monitor for bad
sectors and to remap data to a new location on the media. This feature enhances
the reliability and availability of your data. Compaq also recommends that you
use good back-up procedures, in case of catastrophic failure.
If you discover a failed drive:
■ Identify and document which physical drive has failed. Note the drive
type and capacity.
■ Note which partition and volume, if any, has failed. This information is
provided in the error message on the server console. It is also recorded in
the server error log file, which can be viewed using the SYSCON utility
(intraNetWare 3.12) or NWADMIN utility (NetWare 4.x).
6-7
■ Make sure you have a recent backup. If the drive is part of a fault-
tolerant mirrored volume, or a hardware fault-tolerant volume, you will
be able to back up the data again in case of a second drive failure.
■ Locate a replacement drive of the same type and capacity.
■ Follow the instructions in the following sections for replacing a drive in
your server configuration.

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.NCF and Novell disk drivers. To prevent NetWare from attempting
to read from or write to the failed device, execute the following command from
the console.
REMOVE DOS
Recovering a DOS Partition without Hardware
Fault Tolerance
If your server is not configured for hardware fault tolerance, and if the failed
drive contained the DOS partition used to boot your server, you will not be able
to restart the server once it has been powered off. Schedule maintenance time as
soon as possible and:
1. Power-down your server.
2. Replace the failed drive.
3. Reboot the system with the Compaq System Configuration Utility
diskette.
4. Select the option to Install a System Partition on your DOS boot device.
This partition should contain the Compaq System Configuration Utility
and the Compaq Diagnostic Utility. Exit the System Configuration
Utility.
5. Locate a DOS bootable diskette that contains the DOS FDISK and
FORMAT programs.
6. Use the FDISK program to create a primary DOS partition on the
replaced drive. Compaq recommends that your DOS partition be at least
15 MB.

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. Copy the required disk drivers, LAN drivers, and utility NLMs that
should reside on the DOS partition from the Novell SSD.
11. Copy any other necessary information to the DOS partition, then reboot
your system. You can now start your NetWare server. You may need to
create your STARTUP.NCF file.

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. For example:
NWPA [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
Failure messages are recorded on the server console and also in the
server error log file that can be viewed using the SYSCON utility (3.12)
or the NWADMIN utility (4.x). You will use this information later to
create a valid partition.
2. Load the INSTALL.NLM and select the Disk Options Mirroring menu. Select
the mirrored logical partition that was affected by the drive failure (see Step
1). Record the device number and partition number of the operational logical
drive in this mirrored group. This information will be used later to remirror
the repaired logical drive. For example:
NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
3. Delete the unavailable (possibly out of sync) device from the Mirror
Partition group. This device is unavailable due to the drive failure.
4. Record the drive bay location of the failed physical drive. The new
physical drive must be inserted into this drive bay.
5. If the failed drive is hot-pluggable, Skip to step 6. Otherwise, schedule
server down time, take the server offline, and power-off the unit.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. The
Online LED turns green, indicating that the controller has recognized and
successfully initialized the replacement drive. If the Online LED does
not light after a few minutes, verify that you added the new drive in the
same slot as the failed drive and that the drive capacity is the same as the
failed drive.
7. Activate the replaced device. Use the MONITOR.NLM Disk Information
option to select the device. Some versions of NetWare will cause a
“device activate” to occur automatically when this option is chosen.
Other versions of NetWare require manual activation of the device by
changing the operating status to active. If reactivation of the failed
logical drive is successful, the driver sends a console alert.
8. Use the INSTALL.NLM option Change Hot Fix (look at the information
provided about the mirrored drive, not the failed drive) to determine the
number of Hot Fix Redirection blocks set up for this partition. Refer to
the section “Using CPQDAOPT on NetWare Servers,” in Chapter 5 for
more information about optimizing the performance on NetWare 3.12
servers.
6-11
9. Use the INSTALL.NLM to delete and create the partition on the repaired
logical drive.
NOTE: Although the logical drive may have a valid partition table, the data on
this logical drive is no longer valid. Some data may appear valid because the
failed physical drive was only a portion of the arrayed logical drive. However,
there is a hole in the logical drive data at this point. Delete any old, invalid data
and create a new partition on the logical drive.
10. Return to the INSTALL.NLM Disk Options menu.
NOTE: If you are not running intraNetWare SFTIII or NetWare 4.x, you might
be able to skip to Step 11.
Use the Mirroring selection to locate the Out of Sync partition. The
device number for the Out of Sync partition should match the previously
failed device number. Select the Out of Sync partition.

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.NLM Disk Options menu, select the Partition Tables
option. In the INSTALL.NLM Available Disk Drives menu, select the
previously failed logical drive, which has now been repaired. The device
information was recorded in Step 1. For example:
NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
Select Delete Partition. INSTALL may display several error messages.
Since you will delete this partition, do not update any Volume Definition
Table information. Continue until the partition has been deleted.
If INSTALL reports that it cannot delete the partition because another
process has it locked, load MONITOR and look at the System Resources
option to determine which NLM has locked the device. If it is
MONITOR.NLM, you will need to unload MONITOR and any other
NLMs that have the partition locked. After you create the partition and
volume information, reload those NLMs.
13. Create the partition on the same logical drive.
14. Return to the Disk Options Mirroring menu. Select the previously
mirrored NetWare 386 Partition number (recorded in Step 2).
NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
15. Press Insert for a list of partitions available to remirror. Select the partition
associated with the repaired device (Step 1). This alerts NetWare to
resynchronize the mirrored partitions.
A console message indicates successful completion of the
resynchronization step.

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. They are also
recorded in the server error log file that can be viewed using the
SYSCON utility (NetWare 3.12) or the NWADMIN utility
(intraNetWare). This information will be used later to create a valid
partition.
For hot-pluggable drives in a ProLiant server or storage system, record
the location drive bay of the failed physical drive. The failed physical
device can be identified by the illumination of the amber LED on the
drive tray. This is where the new physical drive must be inserted.
2. Remove the failed drive.
6-13
3. Insert the replacement physical drive in the same drive bay where the
failed drive was located. The physical drive must be the same capacity as
the failed drive.
For hot-pluggable 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 turns green, indicating that
the controller recognized and successfully initialized the replacement
drive. If the Online LED does not light after a few minutes, verify that
you added the new drive in the same slot as the failed drive, and that the
drive capacity is the same as the failed drive.
