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.

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.

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
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.

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.

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.
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

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.
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.

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.

Drives should be of the same capacity to provide the greatest storage space
efficiency when grouped in the same drive array.
■
Except on hot-plug drives in ProLiant servers and storage systems, you must
manually set the SCSI ID on each drive to a unique value in the range 0 to 6 or
8 to 15 for each SCSI bus (ID7 is reserved for the controller). Consult the
documentation that came with the drive for instructions on setting the SCSI ID.

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 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. 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
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. 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.
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
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.

Starting the Array
Configuration Utility
You can access and start the Array Configuration utility either online or by
using the SmartStart and Support Software CD.
Accessing Online
If the server you are configuring is running Windows NT, you can install and
run the configuration utility online.
When you install the Windows NT Software Support Diskette (NT SSD), it
prompts you to insert the Array Configuration Utility diskette to install the
utility. A program icon is available under Compaq Systems Tools group from
the Start menu. Select the icon to run the Array Configuration Utility. The
Windows NT online Array Configuration Utility requires that at least one
logical drive was configured previously while offline.

Configuration Wizards
When you start the Array Configuration Utility, the software checks the
configuration of the Smart Array 3200 Controller and its drive arrays. If the
arrays are unconfigured or if the configuration is less than optimal, the
configuration wizard guides you through the configuration process. The
configuration wizard recognizes the following conditions:
■
Unconfigured controller — When the Array Configuration Utility
detects an unconfigured controller, the configuration wizard leads you
through the controller configuration process.
■
Unused physical drives — When the Array Configuration Utility detects
unused physical drives, the configuration wizard provides an easy way to
add them to an array. The “capacity expansion” capability of the Smart
Array 3200 Controller enables the Array Configuration Utility to add new
physical drives to an existing array without destroying data on the existing
logical drives.
■
Unused space on an array — If the Array Configuration Utility detects
unused capacity in an array, the configuration wizard leads you through the
process of configuring the space into one or more logical drives.
Getting Help
Press the F1 key or click the Help button to activate context-sensitive, online
help for each screen. A status bar at the bottom of the screen also displays help
messages describing the current selection.

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.
■
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.

Running the Array Configuration Utility
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.

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.

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.

This screen first displays the maximum size 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.
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 driverCPQARRAY.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.

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.

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.

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.
■
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.

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

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

an online spare, if one was assigned.
■
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.

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.
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.

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:
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 3.10 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.

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. 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.

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.
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).
■
Make sure you have a recent backup. If the drive is part of a faulttolerant 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.

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.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.

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.

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.
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.
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.

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.
The slot in which the controller is installed does not affect the loading order;
only the order shown in CONFIG.SYS affects the order.
Each ADD driver developed by Compaq places its controllers in ascending
order based on the controller order assigned by the Compaq System
Configuration Utility.
The following rules must be followed for the driver to function properly with
other storage controllers configured in the system.
NOTE: These rules are not automatically enforced by the Compaq System
Configuration Utility. Follow them carefully when configuring the system.
1.
All Compaq array controllers should be in consecutive order as a group.
If booting from a Compaq Smart Array 3200 Controller, the statement
BASEDEV = CPQARRAY.ADD must be present.
2.
Since a Compaq IAES Controller cannot be primary if it is the only other
controller installed in the system, the system must boot from the Smart
Array 3200 Controller (controller order = First).

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. Do
not create partitions exceeding 40 GB on any of the RAID volumes
when running OS/2.
OS/2 may allow the creation of partitions beyond these boundaries; adhere to
these limits, however, to ensure proper functionality.

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. This ensures that the CPQARRAY.ADD driver
is the first ADD driver loaded causes OS/2 to assign the first hard drive on the
first Smart Array 3200 Controller as the boot drive. For example:
BASEDEV=CPQARRAY.ADD
BASEDEV=CPQ53CX.ADD
For OS/2 to boot from another controller, order the other controller first:
BASEDEV=AMSI02.ADD
BASEDEV=CPQARRAY.ADD

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. Under heavy disk use,
this command switch enables greater performance based on the number
associated with the [memory blocks] parameter. The larger the [memory
blocks] parameter, the better the performance under heavy disk use.
When you increase this parameter, the CPQARRAY.ADD driver will
use more memory.
BASEDEV=CPQARRAY.ADD /PERF:[memory blocks]
[memory blocks] is number in the range of 3 to 9 that indicates the
amount of memory blocks allocated per Smart Array 3200 Controller in
the system. The driver runs at a default value of 5. Use this formula to
determine the amount of memory being used:
Number of Smart Array 3200 Controllers * [memory blocks] * 64 KB
Example:
BASEDEV=CPQARRAY.ADD /PERF:6
2.
/V
The Verbose mode command line switch is a standard command line
switch which causes the driver to print information to the screen when it
loads. The driver identifies itself with the current revision. Then
information concerning the adapters and the drives attached to them
displays. Adapter information includes IRQ, slot number, and controller
order number. Drive information includes physical and logical drive
count and the geometry information for each logical drive.
Example:
BASEDEV=CPQARRAY.ADD /V

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.
Example: A system that has three adapters controlled by the
CPQARRAY.ADD, with the lowest configured adapter the secondary
controller.

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.
Example: You are running intraNetWare on your OS/2 2.x system and
you want an intraNetWare NLM to control Adapter 2 instead of the
ADD driver. The following statement would prevent the ADD driver
from claiming Adapter 2.
BASEDEV=CPQARRAY.ADD /A:2 /I

Regulatory Compliance Notices
Federal Communications
Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide an
interference-free radio frequency spectrum. Many electronic devices, including
computers, generate RF energy incidental to their intended function and are,
therefore, covered by these rules. These rules place computers and related
peripheral devices into two classes, A and B, depending upon their intended
installation. Class A devices are those that may reasonably be expected to be
installed in a business or commercial environment. Class B devices are those
that may reasonably be expected to be installed in a residential environment
(i.e., personal computers). The FCC requires devices in both classes to bear a
label indicating the interference potential of the device as well as additional
operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls
into. Class B devices have an FCC logo or FCC ID on the label. Class A devices
do not have an FCC logo or FCC ID on the label. Once the class of the device is
determined, refer to the following corresponding statement.
Class A Equipment
This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct the
interference at personal expense.

frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the
following measures:
■
Reorient or relocate the receiving antenna.

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. This is
supplied in Compaq external storage systems such as the ProLiant Storage
System or SCSI Storage Expander. Therefore, individual SCSI drives in
Compaq storage systems should not contain bus termination.
SCSI IDs
The Smart Array 3200 Controller contains two SCSI buses (ports), each of
which supports up to 15 drives. The internal and external connectors reside on
separate SCSI buses; peripherals attached to either connector must have a
unique SCSI ID in the ranges of 0 to 6 and 8 to 15. SCSI IDs on all peripherals
are either set manually, with switches or jumpers on the device itself, or set
automatically on Compaq products that support hot-pluggable drives. The SCSI
ID determines the device’s priority when attempting to use the SCSI bus. The
highest priority, SCSI ID 7, is reserved for use by the controller.

■ 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.
■

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. An array is made up of
one or more subsets called logical drives (sometimes called logical volumes),
that are spread across all physical drives in the array. Operating systems view
logical drives as a single, contiguous storage space, although it is made up of
parts of several physical drives.
The generic drive array illustrated in Figure E-1 consists of two logical drives
spread across three physical drives. Figures E-2 through E-4 illustrate other
drive array configurations.

include:
■
A single array cannot span more than one Smart Array 3200 Controller.
■
A single Smart Array 3200 Controller can control multiple arrays.
■
Arrays must have at least one physical drive and may have up to 30
physical drives. (The maximum number of drives is limited to the
number of drives that can be installed with the controller.)
■
Arrays consist of at least one logical drive and may have up to 32 logical
drives (maximum 32 logical drives per controller).
■
For maximum space efficiency, all drives in a single array should be the
same capacity.

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.
An array can consist of several logical drives, each spanning all physical drives
in the array. It is important to note that the part of any one logical drive residing
on each physical drive is the same size. This means that, for maximum space
efficiency, all physical drives in each array should always be the same size.
The following are important characteristics of logical drives:
■
There must be at least one logical drive and up to 32 logical drives in an
array (maximum 32 logical drives per controller).
■
Logical drives in an array can be different sizes.
■
Logical drives in an array can use different fault-tolerance methods
(RAID levels).
■
The portion of a logical drive on each physical drive is the same size.

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.
Fault-Tolerance (RAID) Options
During configuration, you will make RAID (Redundant Arrays of Independent
Disks) level choices. RAID is the term used for an array technology that
provides data redundancy to increase system reliability and performance.
RAID levels range from RAID-5 to RAID-0. The Smart Array 3200 Controller
supports the following levels of RAID:
■
RAID 5 - distributed data guarding
■
RAID 4 - data guarding
■
RAID 1 - drive mirroring (also RAID 0+1, or RAID 10)
■
RAID 0 - no fault tolerance (data striping only)
The fault-tolerance method you choose affects the amount of available disk
storage capacity and performance of your drive array. Table E-1 lists the
supported RAID levels and illustrates how the fault-tolerance methods affect
performance and capacity.

RAID 0 offers the best of both parameters. However, RAID 0 has no data
protection and you will have to rely on backups in the event of hardware failure.

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. This allows the
system to continue operating with a slightly reduced performance until you
replace the failed drive.
Distributed data guarding requires an array with a minimum of three physical
drives and allows a maximum of 30 drives. Therefore, in an array containing
three physical drives, distributed data guarding uses only 33 percent of the total
logical drive storage capacity for fault tolerance; a 14-drive configuration uses
only 7 percent, and a 30-drive configuration uses only 3 percent.
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 14.

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.
Data guarding requires a minimum of three drives (two data drives and one
parity drive) in an array and allows a maximum of 30 drives (29 data drives and
one parity drive). For example, in an array containing three physical drives, data
guarding uses only 33 percent of the total logical drive storage capacity for fault
tolerance. A 14-drive configuration (13 data drives, one parity drive) uses only 7
percent; a 30-drive configuration (29 data drives, one parity drive) uses only 3
percent.
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 14.

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. Drive mirroring creates faulttolerance by storing two sets of duplicate data on a pair of disk drives.
Therefore, RAID 1 is the most expensive fault tolerance method because 50
percent of the drive capacity is used to store the redundant data. RAID 1 always
requires an even number of drives. To improve performance in configurations
with more than two drives, the data is striped across the drives. This is also
referred to as RAID 0+1 or RAID 10.
If a drive fails, the mirror drive provides a backup copy of the files and normal
system operations are not interrupted. The mirroring feature requires a
minimum of two drives and, in a multiple drive configuration (four or more
drives), mirroring can withstand multiple simultaneous drive failures as long as
the failed drives are not mirrored to each other.
IMPORTANT: If two drives mirrored to each other fail, the volume is failed
and data loss may occur.

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.
However, because none of the capacity of the logical drives is used for
redundant data, RAID 0 offers the best processing speed and capacity. For this
reason, you may consider assigning RAID 0 to drives that require large capacity
and high speed but do not contain critical data.
Before choosing the RAID 0 option, consider the following:
■
Disk failure will result in data loss for all RAID 0 logical drives.
■
You cannot assign an online spare to an array containing a RAID 0
logical drive.
Online Spare
During configuration, consider assigning an online spare to further improve
your system’s fault tolerance. An online spare (sometimes called a hot-spare) is
a drive the controller uses when a drive failure occurs. If a drive fails, the
controller rebuilds the data that was on the failed drive onto the online spare.
The controller also sends data that it would normally store on the failed drive
directly to the online spare.
The online spare improves the overall system fault tolerance by automatically
replacing a failed drive and quickly restoring the system to full RAID faulttolerance protection. During the time the system is operating in the interim
recovery mode with the failed drive, the system is vulnerable to an additional
drive failure.
You can install up to four online spares for each Smart Array 3200 Controller.
To provide an online spare, you must have at least one installed but unassigned
physical drive and the system must be running some type of fault-tolerance
method (RAID 1, RAID 4, or RAID 5).
Spare drives are assigned automatically to all volumes in an array and can be
assigned to multiple arrays connected to the same controller.

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.
Data striping is automatically generated on an array controller to store user data.
A stripe is a collection of contiguous data that is distributed evenly across all
physical drives in a logical drive. The width of the stripe (the amount stored on
each physical drive) is selected to optimize the performance of the operating
system.

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. Evenly distributed user data across all drives in an array results in improved
performance by allowing data access to all drives simultaneously.

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.

Because data is re-written to the drives in a different format, the Write cache
must be enabled (batteries charged) to protect the data in the event of power loss
during the change. Also, Array Accelerator memory must be large enough to
support the least common multiple of the two different full stripe sizes. During
an expand/stripe-size change from an 11-drive RAID 5 volume (default, 32
sectors; full stripe = 320 sectors) to a 14-drive RAID 1 volume (default, 256

would require 8960 sectors (4480 KB) available in the Array Accelerator.

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. In a new configuration, the area at
the end of the disks is not used if there are not enough sectors left for that
particular stripe-size. To select the new stripe-size, the current configuration
would have to be deleted and the array configured with the new stripe-size.
Since the data would be destroyed, you would need to back up the data and
restore it after the array was reconfigured.
Array Accelerator
By serving as a posted write cache and read-ahead cache, the Smart Array 3200
Controller Array Accelerator dramatically improves the performance of Read
and Write commands. The Array Accelerator is particularly useful for
increasing performance in database and fault-tolerant configurations.
Performance
The Array Accelerator increases performance by having the Smart Array 3200
Controller write data to the cache memory on the Array Accelerator rather than
directly to the drives. The system can access this cache memory more than 100
times faster than accessing disk storage. The Smart Array 3200 Controller
writes the data in the Array Accelerator to the drive array at a later time, when
the controller is otherwise idle.
The controller also uses the Array Accelerator to increase performance by
anticipating requests. The Array Accelerator uses a multi-threaded algorithm to
predict the next likely Read operation for the array. That data is read into the
Array Accelerator and, therefore, is ready before you access it. When the Smart
Array 3200 Controller receives a Read request for the cached data, it can be
burst immediately into system memory at PCI bus speeds.

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. If there is any data in the Array
Accelerator that has not been written to the hard drive, it can be transferred to
another Smart Array 3200 Controller. This might happen if the Smart Array
3200 Controller or server failed before the cached data could be stored on a
drive.
ECC Memory
To assure further data integrity, the Array Accelerator cache is made up of Error
Checking and Correcting (ECC) memory. ECC memory detects and corrects all
single-bit memory errors in multiple DRAMs. It also detects all two-bit memory
errors in any position and most three- and four-bit memory errors in a single
DRAM. An entire DRAM can also fail without data loss. This ensures the
correction of common memory errors without interrupting system operation.

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. If posted Writes were stored in
the memory of the Array Accelerator and power loss occurs, you must reinstate
power within approximately four days or the data stored in the memory will be
lost. This depends on the present condition of the Array Accelerator batteries.
IMPORTANT: It is possible for the batteries to be depleted when you install
a new Smart Array 3200 Controller. It can take up to 36 hours of system
operation to fully charge the batteries. In this case, only the Array Accelerator
is affected; your system will continue to run without interruption.
During Power-On Self-Test (POST), the Smart Array 3200 Controller checks
the batteries. If the battery charge is low or depleted, a 1794 POST error
message displays, indicating that the Array Accelerator is disabled. The
controller temporarily disables the Array Accelerator until the batteries reach 90
percent charge. The board continues to function properly, but at a slightly lower
performance until the batteries reach 90 percent charge. At this point, the Array
Accelerator is enabled automatically.

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.

Concurrent request servicing handles several I/O requests
Optimized Request Management
Optimized Request Management, also known as elevator trend sorting, is
another performance enhancement feature provided by the Smart Array 3200
Controller. The controller receives and queues multiple data requests from the
operating system. The controller then rearranges the requests in an order that
optimizes performance.
For example, the Smart Array 3200 Controller receives a request for a physical
drive that is not currently active. The controller schedules the request
immediately ahead of previously received requests already queued to other
active drives within the array. This request management process operates
concurrently with drive operations. The benefits of optimized request
management increase as greater demands are made on the drive subsystem.

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. Bus master high-speed transfers are particularly
important when the supported models are used in conjunction with multiple
expansion boards such as network interface controllers (NICs).
Adding Storage Capacity
Capacity expansion is increasing the size of an array by adding physical drives
and creating additional logical drives. Capacity extension refers to increasing
the size of an array by adding physical drives and increasing an existing logical
drive without adding more logical drives.
The Smart Array 3200 Controller enables the configuration of one or more
separate logical drives into a single drive array. The controller also supports
extending the capacity of an existing logical drive. An existing drive array can
be expanded by adding one or more logical drives to the array or by increasing
the capacity of an existing logical drive. To create the room for the additional
logical drives, more physical drives must be added. See Figure E-10.

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. The room left over is used to increase the size of a logical drive or
to create additional logical drives, also spanning all physical drives. The
extended logical drive is writing the larger drive array. When logical drives are
added, both logical drives are then included in the drive array with expanded
storage capacity. See Figure E-11.

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. The Array
Configuration Utility also detects the unused space on each drive (because each
drive contains 10/14ths of the data it used to contain) and helps you configure it
into a second logical drive with its own fault tolerance distributed over the extra
space of all the drives.
When this process is finished, both logical drives,–,one containing the original
data and the new empty drive,–,will be configured into a single array with more
total capacity than the original drive. Now your array will resemble
Figure D-11, using the same shading scheme to represent the logical drives.
It is not necessary for all logical drives in an array to be the same size or even
have the same fault-tolerant configuration. Each logical drive is treated as a
separate entity no matter how many physical drives it crosses. Each may be
configured to best suit your needs.
It is important to remember that all physical drives in an array should be the
same size (capacity). This is because each drive contains an equal portion of one
or more logical drives and the portion sizes can only total the size of the
smallest drive. While you are not prevented from expanding storage capacity
with larger drives, the extra space cannot be used.
During expansion of an array that initially has two or more logical drives,
redistribution of data takes place one logical drive at a time. When the capacity
expansion has completed, any newly created logical drive will become
available. Under Windows NT and NetWare, the new logical drive can then be
appended to your existing logical volume.

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 3.11 not supported)
and
■
Hot-plug drives
Because the Array Configuration Utility reconfigures the Smart Array 3200
Controller, online reconfiguration can only take place if the Array Configuration
Utility is running in the same environment as the normal server applications.
Hot-plug drives are required for online storage changes because non-hot-plug
drives require that the server be powered-down to add or remove the drive. All
ProLiant servers and storage systems support hot-plug drives.
Disk Drive Upgrades
Additional storage space can be gained with the same number of physical drives
in a fault-tolerant configuration by replacing these drives with higher-capacity
drives. By replacing the drives one at a time, the data on the new drive is
recreated from redundant information on the remaining drives. After one new
drive has been rebuilt, the next drive can be replaced. After all drives have been
replaced and rebuilt, the additional capacity on each drive can be used by
increasing an existing logical drive or adding a new logical drive. The Array
Configuration Utility automatically recognizes the unused space and guides you
through the procedures to use it.

Online capacity extension under Windows NT requires version 5.0 or later.

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.
Dynamic-Sector Repairing
Using the dynamic sector repairing process, the controller automatically remaps
any sectors with media faults it detects either during normal operation or during
auto-reliability monitoring.
Drive-Parameter Tracking
Drive-parameter tracking monitors more than 15 drive-operational parameters
and functional tests. This includes parameters such as Read, Write, and seek
errors, spin-up time, cable problems; functional tests such as track-to-track seek
time, one-third stroke, and full stroke seek time. Drive parameter tracking
enables the Smart Array 3200 Controller to detect drive problems and predict
drive failure before they actually occur. It also makes pre-failure warranty
possible on Compaq disk drives.
Drive-Failure Alert Features
Drive-failure features produce various drive alerts or error messages depending
on the Compaq server model. Refer to the documentation included with your
server to determine what drive-failure features are included on your server
model.
Other Compaq options, such as Compaq Insight Manager and Compaq Server
Manager/R, provide additional drive-failure features. See your Authorized
Compaq Reseller for more information on these products.

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. See Appendix G for
more information on drive failure recovery.
Automatic Data Recovery
After you replace a failed drive, automatic data recovery reconstructs the data
and places it on the replaced drive. This enables a rapid recovery to full
operating performance without interrupting normal system operations.
In general, the time required for a rebuild is approximately 15 minutes per GB.
However, the actual rebuild time depends on the rebuild priority set for the
amount of I/O activity occurring during the rebuild operation, disk drive speed,
and the number of drives in the array (RAID 4 and RAID 5). In RAID 4 and
RAID 5 configurations, the rebuild time varies from 10 minutes per GB for
three drives to 20 minutes per GB for 14 drives (using 9-GB Wide-Ultra hard
drives).
NOTE: You must specify RAID 5, RAID 4, or RAID 1 through the Array
Configuration Utility to make the recovery feature available. The drive failure
alert system and automatic data recovery are functions of the Smart Array
3200 Controller; they function independently of the operating system.

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.
CAUTION: Do not turn off the Compaq ProLiant Storage System
or the Compaq server when removing or installing the hot-plug
replacement drives. If you turn off the ProLiant Storage System
while the server power is on, the Smart Array 3200 Controller
marks all drives as “failed.” This could result in permanent data
loss when the Storage System is turned back on.
If a drive fails, the service-required LED on the front panel of the Compaq
ProLiant lights, indicating that a problem has occurred. Refer to your server
documentation for more information on replacing drives. Also see Figure E-12
for conditions to safely replace a drive using the three indicators on each of the
hot-plug drive trays.

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. Controller duplexing is a function of the operating
system and takes the place of other fault-tolerance methods. Refer to the
documentation included with your operating system for implementation.
Compaq recommends using hardware-based fault tolerance instead of controller
duplexing. Hardware-based fault tolerance provides a much more robust and
controlled environment for fault-tolerance protection.
If you choose controller duplexing, configure each Smart Array 3200 Controller
with RAID 0 to achieve maximum storage capacity. In addition, the following
fault-tolerant features will not be available: online spare, auto-reliability
monitoring, interim data recovery, and automatic data recovery.

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. If you mirror logical drives in the
same array and a physical drive fails, both logical drives in the mirrored pair
will also fail. You will not be able to retrieve your data.
Because software-based drive mirroring is a function of the operating system,
refer to the documentation included with your operating system for
implementation.
Compaq recommends using hardware-based fault tolerance instead of softwarebased fault tolerance. Hardware-based fault tolerance provides a much more
robust and controlled environment for fault-tolerance protection.
If you choose software-based drive mirroring, create at least two arrays with
RAID 0 to achieve maximum storage capacity. Then, when you configure the
drive mirroring through the operating system, mirror the logical drives residing
in different arrays. In addition, the following fault-tolerant features will not be
available: online spare, auto-reliability monitoring, interim data recovery, and
automatic data recovery. See Chapter 5 for information on your drive array(s)
and fault tolerance.

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.
The Smart Array 3200 Controller Array Accelerator has several unique features:
■
It accelerates data storage by temporarily caching the data at high
internal bus rates while transferring the data to the drives at their slower
Write speeds.
■
It uses its own batteries to keep the data alive without board power, even
if the Array Accelerator is removed from the Smart Array 3200
Controller.
■
The memory is Error Checking and Correcting (ECC), providing error
detection and correction reliability.
■
It can be moved to another Smart Array 3200 Controller to complete the
data transfer should the original Smart Array 3200 Controller fail.

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.
IMPORTANT: Array configuration information is automatically transferred
during the upgrade process. However, this is a one-way process. After
upgrading to the Smart Array 3200 Controller, a manual reconfiguration
procedure is required to move the drives and data back to the SMART or
SMART-2 Controller.
IMPORTANT: The upgrade procedure described below applies only to
moving drives from SMART or SMART-2 controllers to the Smart Array 3200
Controller. Data will NOT be preserved if drives are moved from a Fast SCSI-2
Controller or a Fast-Wide SCSI-2 Controller to a SMART, SMART-2, or Smart
Array 3200 Controller.
To upgrade your system by replacing the SMART or SMART-2 SCSI Array
Controller with a new Smart Array 3200 Controller, perform the following steps
in the order indicated.
1.
Back up all affected drives. This is a safety precaution. If done properly,
this upgrade procedure will not affect the arrayed data or drive location.
2.
Upgrade your operating system device driver to the new Smart Array
3200 Controller driver. The new drivers have been optimized to support
the latest features and capabilities of the Smart Array 3200 Controller.
The driver upgrade process is operating system-dependent. See the
Readme file on the Compaq SmartStart and Support Software CD for
information on specific operating system drivers.

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. Otherwise,
Systems ROMPaq is distributed on the Compaq SmartStart and Support
Software CD included in the Smart Array 3200 Controller option kit.
Review Chapter 3 in this guide for specific instructions on running
Systems ROMPaq.
4.
Perform a normal shutdown and turn OFF the server.
5.
It is important to understand the difference between SCSI cable
connector layouts for the SMART Controller, SMART-2 controllers, and
Smart Array 3200 Controllers. See Figures F-1 and F-2.
The SMART Controller has a 100-pin external connector on the
mounting bracket that connects to the Y cable that separates into two
50-pin Fast-SCSI-2 connectors, Port 1 and Port 2. These port numbers
should be labeled on the Y cable and can be connected to external drives
in Compaq ProLiant Storage Systems or other external storage units.
Port 1 is also available as an internal connector on the top edge of the
controller for internal drive connections. Port 1 can be used either
internally or externally, but not both at the same time. Note the existing
cable connections and port numbers for your system before
disconnecting any cables.
The SMART-2DH Controller has an external 68-pin Fast-Wide SCSI-2
connector on the mounting bracket for Port 2 only. There is an internal
68-pin Fast-Wide SCSI-2 connector at the top edge of the controller for
Port 1. This port can be used for internal drives through a standard
internal ribbon cable, or for external drives through a special
internal/external cable (included) and a connector panel or slot connector
bracket (included) at the back of the server. This enables Port 1
connections to external drives in Compaq ProLiant Storage Systems.
There is no Y cable used with the SMART-2DH Controller.

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

daughterboard to use your existing 50-pin internal ribbon cable.
❏
If you are connecting to a Fast-SCSI-2 external storage system, use
a VHDCI to 50-pin external cable, which must be ordered
separately.
❏
If you are connecting to a Fast-Wide SCSI-2 external storage
system, use a VHDCI to 68-pin external cable included with the
ProLiant Storage System.
For more detailed information on cable connections for your system,
refer to your server documentation.

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. Multiple
drive failures in the same array generally result in data loss (exceptions include
failures following the activation of a spare drive and failure of drives in a
mirrored configuration that are not mirrored to one another).
Recognizing a Drive Failure
A drive failure can be recognized in one of several ways:
■
Amber LED illuminates on failed drives in a hot-pluggable tray. This,
however, assumes that the storage system is powered-on and the SCSI
cable is working. Note that the amber LED may illuminate briefly when
a hot-pluggable drive is inserted; this is normal.
■
Amber LED illuminates on the front of a ProLiant Storage System if
failed drives are inside. (Other problems such as fan failure or overtemperature conditions will also cause this LED to illuminate.)
■
A Power-On Self-Test (POST) message lists failed drives whenever the
system is restarted, assuming that the controller detects one or more
“good” drives. (See Appendix I for explanation of POST messages.)
■
Array Diagnostic Utility(ADU) lists all failed drives. An online version
of ADU is also available in Windows NT environments.
■
Compaq Insight Manager can detect failed drives remotely across a
network.

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.
At any one time, if more drives are failed than the fault-tolerance method
allows, fault tolerance is “compromised” and the condition of the logical drive
can be referred to as “failed.” If a logical volume is “failed,” all requests from
the operating system will be rejected with “unrecoverable” errors.
A Non-Fault-Tolerant (RAID 0) Logical Drive
A Non-Fault-Tolerant (RAID 0) logical drive can sustain no drive failures. If
any physical drive in the array is failed, the condition of all non-fault-tolerant
logical drives in the same array will also be “failed” because data is striped
across all drives in the array.
A RAID 1 (Mirroring) Logical Drive
■
Can sustain multiple drive failures as long as failed drives are not
mirrored to one another
■
Will be in a “failed” condition if any two failed drives are mirrored to
one another
■
Will be in a “regenerating” condition if at least one drive is failed and no
failed drives are mirrored to one another
■
Will be in a “rebuilding” condition if a previously failed drive has been
replaced and the replacement drive is rebuilding. The volume may also
be in a “rebuilding” condition following a drive failure if a spare drive
was previously assigned and is being rebuilt.
In any RAID 1 logical drive on the Smart Array 3200 Controller tht has N
physical drives in the array (not including spare drives), the first N/2 physical
drives are normally mirrored in consecutive order to the second N/2 physical
drives. When determining the order, number each drive in the array by
increasing IDs on the first SCSI bus, followed by drives on the second SCSI
bus.

COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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. Note,
however, that if another drive fails before the spare drive is completely built, the
spare drive cannot prevent failure of the entire logical drive. Also note that it is
possible for non-correctable disk errors to prevent completion of the Automatic
Data Recovery process (discussed below).
Replacing a Failed Drive
Failed drives in hot-pluggable trays can be removed and replaced while host
system and storage system power are both ON. Hot-pluggable drives can also be
replaced when the power is OFF. Remember, however, to never turn off an
external storage system while the host system power is on. This results in the
failure of all drives in the storage system, which would likely compromise your
fault tolerance. When a hot-pluggable drive is inserted, all disk activity on the
controller is temporarily paused while the drive is spinning up (usually 20
seconds or so). If the drive is inserted while power is ON, in fault-tolerant
configurations, recovery of data on the replacement drive begins automatically
(indicated by blinking online LED).
Non-hot-pluggable drives should only be replaced while the system power is
OFF. On all non-hot-pluggable drives, be sure to check the SCSI ID jumpers to
make sure the correct drive is being replaced. To prevent compromising the
fault tolerance, it is imperative that the correct physical drive be replaced.
Also, be sure that the SCSI ID jumpers are set to the same SCSI ID on the
replacement drive. The SCSI ID jumpers may be located at different places on
different drive models, but it is necessary that the SCSI ID on the replacement
drive always be set to the same value as the original failed drive to prevent

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.
In some cases, a drive that has previously failed by the controller
may appear to be operational after the system is power-cycled, or
after removal and reinsertion of a hot-pluggable drive. However,
this practice is highly discouraged as the use of such “marginal”
drives may eventually result in data loss.
Automatic Data Recovery
If a drive in a fault-tolerant configuration is replaced while the system power is
OFF, the controller displays a Power-On Self-Test (POST) message during the
subsequent system startup. This indicates that the replacement drive has been
detected and that Automatic Data Recovery might need to be started. Press F1
to initiate the background Automatic Data Recovery process. If Automatic Data
Recovery is not enabled, the logical drive remains in a “ready-to-recover”
condition and the same query displays at the next system restart.
Replacement drives are not considered to be “online” until Automatic Data
Recovery is completed, at which time the online LED stops blinking and is on
“solid.” Any drives that are not yet “online” are treated as if they are “failed”
when trying to determine whether fault tolerance will be compromised. For
example, in a RAID 5 logical drive with no spare and one drive rebuilding,
another drive failure at this time would result in a “failure” condition for the
entire logical drive.
In general, the time required for a rebuild is approximately 15 minutes per
gigabyte. The actual rebuild time, however, depends upon the rebuild priority
set for the amount of I/O activity occurring during the rebuild operation, the
disk drive speed, and the number of drives in the array (RAID 4 and RAID 5).
In RAID 4 and RAID 5 configurations, the rebuild time varies from 10
minutes/GB for three drives to 20 minutes/GB for 14 drives (using 9-GB wideultra hard drives).

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. Reboot the system and a POST message should confirm the
diagnosis. Retrying Automatic Data Recovery may help. If not, a backup of all
data on the system, surface analysis (using User Diagnostics), and restore is
recommended.
During Automatic Data Recovery, if the online LED of the replacement drive
stops blinking and the replacement drive is failed (amber failure LED
illuminated or other LEDs go out), the replacement drive is producing
unrecoverable disk errors. In this case, the replacement drive should be removed
and replaced.

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. In some cases, an intermittent drive will
appear to work again (perhaps long enough to make copies of important files)
after cycling power. If a 1779 POST message is displayed, press F2 to re-enable
the logical drive(s). Remember that data loss has likely occurred and any data
on the logical drive is suspect.
Fault tolerance may be compromised due to non-drive problems such as a faulty
cable, faulty storage system power supply, or an end user accidentally turning
off an external storage system while the host system power was on. In such
cases, the physical drives do not need to be replaced. However, data loss can
occur, especially if the system was busy at the time the problem happened.
In cases of “legitimate” drive failure, once copies of important data have been
made (if possible), replace any drives that have failed to prevent further drive
problems in the future. After these (multiple) drives are replaced, fault tolerance
may again be compromised, power may need to be cycled, and the 1779 POST
message may again be displayed. Press F2 to re-enable the logical drive(s),
recreate your partitions, and restore all data from backup.
Because of the risk that fault tolerance may be compromised at some point in
the future, make regular backups of all logical drives.

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.
The maximum number of internal and external drives that you can install in
your system also depends upon your server and your choice of hard drives.
Each Smart Array 3200 Controller has two SCSI buses, and each bus can
support up to 15 drives.
Q. Does the Smart Array 3200 Controller support SCSI tape drives and
CD-ROM drives?
A. No; the Smart Array 3200 Controller only supports Wide-Ultra2 SCSI,
Wide-Ultra SCSI-3, Fast-Wide SCSI-2, and Fast SCSI-2 hard drives.
Q. I installed the hard drives in my server. Must I now terminate each
drive?
A. No; if you install hard drives in a server with a Smart Array 3200
Controller, all termination requirements are met by the controller and the
SCSI signal cable. Therefore, the individual drives should have termination
removed.

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.
They do not need to be manually set.
If your drives are installed in a Compaq ProSignia, ProSignia 500,
ProSignia 300, ProSignia VS, or Systempro/XL, you must manually set the
SCSI ID jumpers.
Q. Should SCSI IDs in my system be consecutive?
A. No. It is no longer required that the IDs of devices on each SCSI bus be
consecutive. However, IDs must still be unique for each device on a single
SCSI bus.
CAUTION: Do not interchange SCSI IDs after you configure your
Smart Array 3200 Controller. Interchanging the SCSI IDs will result
in loss of data.
Q. I am planning to install several 2.1- 4.3- and 9.1-GB Fast-SCSI-2 Hard
Drives in my Compaq servers. Can I install one of these drives in any
drive bay?
A. In the ProLiant and ProSignia servers, you may install these drives in any
drive bay; they do not need to be installed in contiguous bays. In
Systempro/XL servers, the 2.1- 4.3- and 9.1-GB Fast-SCSI-2 Hard Drives
must only be placed in the four bays in the upper row.

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. If you have no hard drives installed in your server, you can connect the
Compaq ProLiant Storage System to either port.
CAUTION: Do not interchange these connectors after you
configure your Smart Array 3200 Controller. Interchanging the
connectors could result in a loss of your data.
If you have hard drives installed in your server and connected to the
Smart Array 3200 Controller, only one port will be available externally.
Q. I want to connect two Compaq ProLiant Storage Systems to my server.
Can I also connect the internal hard drives in my server to the Smart
Array 3200 Controller?
A. No. If you connect two ProLiant Storage Systems to your server, you
cannot connect any internal hard drives in your server to your Smart Array
3200 Controller because both SCSI ports will be used externally. You can
add an additional Smart Array 3200 Controller to your server to control any
internal drives.
Q. What must I do with Systems ROMPaq?
A. Run Systems ROMPaq to upgrade the firmware in your server to the latest
revisions prior to installing a Smart Array 3200 Controller in an existing
system. Otherwise, the system may not reboot if the Smart Array 3200
Controller is the primary controller.

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. See Appendix
H , “POST Error Messages,” for information on each POST error message.
If you still do not know what to do, run the Array Diagnostics Utility.
Q. Can I use third-party (not Compaq) drives on the Smart Array 3200
Controller?
A. Although you can use third-party drives, experience in Compaq testing
laboratories reveals that you might have problems such as time-outs, data
corruption, and so on. The Smart Array 3200 Controller takes full
advantage of SCSI tagged-command queuing, something that can be a
problem in the firmware of many third-party drives. Also, Compaq drives
feature a unique pre-failure warranty. Contact your dealer for more
information on a Compaq Pre-failure Warranty.
Q. Why do the drive activity lights light up on some drives when my
system is idle?
A. The Smart Array 3200 Controller performs several different background
activities on the drives when the controller is otherwise idle. For example,
the Auto-Reliability Monitoring task scans fault-tolerant volumes for
defects and verifies the consistency of parity data. The Drive Parameter
Tracking task periodically checks the performance of all drives on the
controller, usually on an hourly basis.
