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 non-arrayed drives.
Each logical drive in the array may be set to a different fault tolerant
configuration. The SMART-2DH Array Controller manages the drive array
independent of the host processor.
There may be several possible ways to configure each set of hardware. The
Array Configuration Utility is used to help you configure the hardware in the
way that best suits your needs.
1-3
See Appendix D for more information on drive arrays. See Chapter 5,
“Running the Array Configuration Utility,” for information on configuring
your drive arrays using the Compaq Array Configuration Utility.
Fault Tolerance
Fault tolerance refers to several possible methods used to protect data from
being lost in the event of a hardware failure somewhere in the storage system.
Each method has its advantages, so choosing one requires careful planning for
your particular requirements.
The fault tolerance methods supported by the SMART-2DH Array Controller
and the Compaq Array Configuration Utility include:
■ Distributed data guarding (RAID 5)
■ Data guarding (RAID 4)
■ Drive mirroring (RAID 1)
■ No fault tolerance (RAID 0)
CAUTION:
It is recommended that any time you move drive
arrays or change your configuration you should back up data.

Features
Further data protection can be achieved by assigning an online spare to any
RAID 1, RAID 4, or RAID 5 configuration. See Appendix D for more
information on these fault-tolerance methods. See Chapter 5 for information on
configuring your system for one of the fault tolerance methods.
Capacity Expansion
Capacity Expansion refers to the ability to change an existing data storage
configuration. This change usually involves adding drives to provide more
storage space.
Using the Array Configuration Utility, changing your storage configuration is
easy, even in fault-tolerant configurations, without requiring a data backup
and restore cycle. If you are using Microsoft Windows NT or Novell NetWare
operating systems with hot-pluggable drives, storage expansion can also be
performed online, without shutting down the server operating system. For
more information on storage expansion, see Appendix D, “Understanding
Drive Arrays.”
Drive Movement
An array of drives can be moved from one system to another as long as the
relative order of the drives is maintained. For more information, see Chapter
2.

Wide-Ultra SCSI, Fast-Wide SCSI-2, and Fast-SCSI-2
The SMART-2DH Array Controller complies with ANSI SCSI-2 standards,
supporting 16-bit Wide-Ultra SCSI, 16-bit Fast-Wide SCSI-2, and 8-bit FastSCSI-2 (standard SCSI) devices.
Wide-Ultra SCSI
Wide-Ultra SCSI technology provides SCSI data transfer rates of up to
40-Mbytes/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 of 20-Mbytes/sec data rate between SCSI devices while still
maintaining a 10-MHz bus rate.
Compaq Fast-Wide SCSI-2 controllers and devices are able to communicate
using Fast-SCSI-2 protocol when required. Therefore, Fast-SCSI-2 drives may
also be used with SMART-2DH Array Controller using the appropriate cable
adapter.
1-5
Array Accelerator
The SMART-2DH Controller Array Accelerator provides a 16-MB onboard
write cache. The result is improved performance on data access to the drive
array by serving as a posted-write cache and read-ahead cache. The write
cache can accept data from the server at 60 megabytes per second. At the
same time, read and writes caches can be accommodated by the drivers. The
read-ahead cache uses a multi-threaded algorithm to predict the next likely
read operation for the array. That data is then read into the Array Accelerator
from the drives. When the SMART-2DH Array Controller receives a read
request for the cached data, it can be brought immediately into system
memory bus speeds. The Array Accelerator feature may be disabled by
software if desired.

Features
: The SMART-2DH Controller Array Accelerator is equipped with a
NOTE
switch that may be activated to fine tune system performance. See Appendix
E for further information.
The Array Accelerator is made of ECC (Error Checking and Correcting)
memory, providing 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,
ensuring that the data temporarily held (cached) there is safe even with
equipment failure or power outage. 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-2DH Array
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 is not a problem that requires action on your
part. The Array Accelerator is automatically enabled when the batteries are
charged to 90% of their capacity.
It may take up to 36 hours for the internal circuitry to charge the batteries
fully. During this time, the Array Accelerator will be disabled, but the
SMART-2DH Array Controller will function properly, although without the
performance advantage of the Array Accelerator.
The Array Accelerator, with backup batteries, is located on a removable
daughter board. In the unlikely event of failure, the Array Accelerator can be
detached from the failed SMART-2DH Array Controller and attached to a
replacement SMART-2DH Array 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 is automatically written 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-2DH Array Controller board.

Chapter 2
Guidelines for Making Changes
to Current Installation
Multiple SMART-2DH Controller
Installation
When you install more than one SMART-2DH Array Controller in the same
server, the following considerations apply:
■ Each SMART-2DH Controller has two independent SCSI channels,
each of which supports up to seven drives.
■ Each SCSI channel has its own set of unique SCSI IDs (from 0 to 6).
You must assign each peripheral on the bus a unique ID for that bus.
Since only one of the two SCSI ports is available on its external connector, the
other internal port must be brought out to an external connector if it is to be
used for external storage. In some servers, a connector panel is provided for
this purpose, but in others the internal port is brought out through an unused
option slot using a special connector bracket.

Guidelines for Making Changes to Current Installation
Drive Considerations
If you will be installing or replacing drives in your Compaq server, keep in
mind that:
■ Drives may be Fast-SCSI-2, Fast-Wide SCSI-2, Wide-Ultra SCSI, or a mixture
of the three in servers and storage systems supporting hot-pluggable drives.
■ Drives should not contain termination. Compaq servers and internal
cabling provide the required termination of the SCSI bus.
■ Compaq hard drives supported by the SMART-2DH Controller
include:
1.05-GB Fast-SCSI-2
2.1-GB Fast-SCSI-2
2.1-GB Fast-Wide SCSI-2
2.1-GB Wide-Ultra SCSI
4.3-GB Fast-SCSI-2
4.3-GB Fast-Wide SCSI-2
4.3-GB Wide-Ultra SCSI
9.1-GB Wide-Ultra SCSI
9.1-GB Fast-SCSI-2
18.2-GB Wide-Ultra SCSI 3
■ Drives should be of the same capacity to provide the greatest storage space

■ 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 of 0 to
6 for each SCSI bus. Consult the documentation that came with the drive for
instructions on setting the SCSI ID.
Determining the Maximum Storage
Maximum storage capacity factors of a server include:
■ subtract any option slots used for other purposes
■ available internal drive bays
■ availability of external connectors for SCSI Bus 1 (requires connector
panel location or vacant option slot)

■ some operating systems limit number of logical drives or drive controllers
The maximum number of controllers and drives supported depends on several
factors. To determine the number of drives supported by your server, refer to
the Setup and Installation Guide, or Reference Guide, that accompanied your
server. Server specifications are also available at our website,
www.compaq.com.
Expanding the Capacity of an Array
Below is an overview of procedures for expanding the capacity of an array.
1. Review. See Appendix D, “Adding Storage Capacity,” for information
on expanding the storage capacity of an existing SMART-2DH 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. 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 offline. Simply plug the new drives into
vacant bays.
2-3
4. Configure drive array. See “Capacity Expansion” in Chapter 5 for
instructions on using the Compaq Array Configuration Utility to
reconfigure your drive array to make use of the added capacity. If your
operating system supports it, run the Array Configuration Utility online
to guide you through the process. The controller automatically
redistributes the data.

Changing the Fault Tolerance
An overview of the procedures to change the fault tolerance is provided
below.
1. Decide on a fault-tolerance method. Review Appendix D,
“Understanding Drive Arrays,” and choose the fault-tolerance method
that best suits your needs.
2. Back up data. Changing the fault tolerance will destroy the data on
that logical drive. You must back up all data in the logical drive that
you will be changing.
3. Configure drive array. Proceed to Chapter 5, “Running the Array
Configuration Utility,” for information on reconfiguring your drive
array with the new fault-tolerance method.
4. Restore data. Copy the backed-up data into the same logical drive.
Your system automatically redistributes the data according to the new
fault-tolerance method.
Moving Drives
Drives can be moved to alternate ID positions on the same array controller as
long as their relative positions remain unchanged. (For information on moving
arrays from one controller to another, see the section in this chapter, “Moving
Arrays.”) Although data loss is not anticipated during drive movement, it is
recommended you back up data before moving drives. To move drives, the
following conditions must be met:
■ Controller firmware is the latest revision (currently 2.02).
■ System power is OFF (includes all system components).
■ The move will not result in more than 7 physical drives and/or 32
logical drives (volumes) connected to a single controller.
■ No failed drives identified. The array should be in its original
configuration with no active spare drives.
■ Capacity expansion is not running.
■ Drives in each array must maintain same the same relative positions
before and after drive movement as shown in Figure 2-1.

The original configuration in Figure 2-1 shows drive positions 0, 3, and 6
filled. The drives are moved to positions 0, 1, and 2. In both configurations,
the relative order of the drives stays the same: a, then b, then c. This example
would not work if the new configuration changed the relative orders of the
drives, that is, b, then a, then c. The new positions can also span multiple
buses as long as the relative order remains the same; in this case, think of
drive IDs 0 and 1 on SCSI port 2 as IDs (positions) 7 and 8. SCSI cables
cannot be interchanged if an array spans the two ports.

Moving Arrays
Moving arrays 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 of the drives in the array must be moved at the same time.
■ Positions of drives on the destination controller should not be moved 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 have previously moved an array and plan to restore it to its
original controller, see the following section, “Restoring an Array to Its
Original Controller.”
Figure 2-2 shows an original distributed configuration with two controllers,
each having one array: drive IDs 0, 1, 2, and 3 constitute Array A on
Controller 1 and drive IDs 0, 1, and 2 constitute Array A on Controller 2.
Figure 2-3 shows that after removing the array from Controller 2 and adding it
to Controller 1, Controller 1 has two arrays: drive IDs 0, 1, 2, and 3 constitute
Array A and drive IDs 4, 5, and 6 constitute Array B. Controller 2 has no
arrays.
: A spare can be added as part of an array during this process.
NOTE
However, it will not be restored as a spare until you run Array Configuration
Utility on the newly configured array.

Updating the Firmware
The ROMs on all Compaq servers and most Compaq options can be updated
easily. This is done by flashing the ROM using a special Compaq utility called
ROMPaq, which replaces the existing contents of the ROM with another
version stored in a disk file. This is a convenient way to distribute new
firmware to keep Compaq products updated with the latest capabilities.
There are two ROMPaq utilities:
System ROMPaq for updating the system ROM in all Compaq servers
supporting Flash ROM. Use System ROMPaq when
installing a new SMART-2DH Controller in a Compaq
server to be sure that the server can utilize all the
capabilities of the SMART-2DH Array Controller.
Option ROMPaq for updating the onboard ROM on all Compaq options that
support flashing. Use Option ROMPaq when new versions
of the SMART-2DH Array Controller firmware or SCSI
drive firmware become available to take advantage of
expanded capabilities.
3-1
IMPORTANT:
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-2DH Controller.
ROMPaq Diskettes
The ROMPaq utilities must be run from diskette(s). The latest version of the
ROMPaq diskettes may be created from the Compaq SmartStart and Support
Software CD that was supplied in the SMART-2DH Controller Option Kit.
We recommend that you initially use this version of ROMPaq because it is the
latest one that supports your new SMART-2DH Controller.

Running System ROMPaq
System ROMPaq is used to update the firmware in Compaq servers. The
SMART-2DH Controller has enhanced drive array capabilities; many existing
servers may not be able to take advantage of these capabilities without
updated firmware. 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-2DH Controller. If you
purchased your server with the SMART-2DH Controller already installed, you
do not need to run System ROMPaq at the time of server installation.
3-3
CAUTION:
If you are replacing an existing array controller,
such as the Compaq SMART Array Controller, with the SMART2DH Controller, the system may not boot after hardware
installation. It may not boot 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-2DH Controller you should run System ROMPaq
before
you make the hardware installation. This will ensure that
the server will recognize the SMART-2DH Controller and not hang
up on boot.
To run System ROMPaq:
1. Place the System ROMPaq diskette in the server diskette drive.
2. Boot the server by turning on the power.
3. Press Enter at the Welcome screen.
4. At the Select A Device screen, select the server from the list of the

Configuration Wizards
When you start the Array Configuration Utility, the software checks the
configuration of each SMART-2DH Array Controller board and its drive
arrays. If the arrays are unconfigured or if the configuration is less than
optimal, the configuration wizard takes over to guide you through the
configuration process. The configuration wizard recognizes the following
conditions:
5-5
■ Unconfigured controller - When the Array Configuration Utility
detects an unconfigured controller, the configuration wizard takes 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 SMART2DH Array Controller allows the Array Configuration Utility to add the
new physical drives to an existing array without destroying the 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 takes you through the
process of configuring the space into one or more logical drives.

Configuration Procedures
Creating a New Array
If you are configuring a new array, the configuration wizard leads you through
the process. If you want to bypass the wizard, use the following procedures to
create your array.
Creating a New Array—Procedure
Creating a new array involves the following general steps:
1. Choose a controller for the array.
2. Group physical drives of the same size into an array.
3. Subdivide the array into one or more logical drives.
The following example illustrates using the Array Configuration Utility to
carry out these steps.
Creating a New Array—Example
For this example, make the following assumptions:
■ Four 1.05-GB drives and two 4.3-GB drives are connected to the
SMART-2DH Array Controller.
■ There will be two arrays. Array A consists of three 1.05-GB drives
with the fourth 1.05-GB drive used as a spare. Array B is the two 4.3GB drives.

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-2DH
Array Controller capacity expansion feature provides a way to add a new
physical drive 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 of adding the drive.
: You cannot use the Capacity Expansion feature if the disk controller
NOTE
is configured for use with the Recovery Server option. In order to expand an
array when the controller is configured for the Recovery Server option:
1. Use the System Configuration Utility to turn off the Recovery Server feature,
2. Enter the Array Configuration Utility and use the capacity expansion feature,
3. After the expansion is complete, use the System Configuration Utility to
enable the Recovery Server feature.
5-15
Capacity Expansion Procedure
If you wish to bypass the configuration wizard for some reason, you may use the
procedures that follow to expand your array.
■ Install the new physical drive(s).
■ Assign the new physical drive(s) to an existing array. Existing logical
drive(s) will automatically expand across all of the physical drives,
including the newly added one(s).
■ Create a new logical drive to use the extra space on the expanded
array.

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

Error and Warning Messages
When you start the Array Configuration Utility, the software checks each
controller to detect errors in its configuration. If a problem is found, the Array
Configuration Utility displays an error or warning message that describes the
problem. Error and warning messages include instructions to correct
configurations. If a warning message indicates “Internal Error Has Occurred” and
cites an error code number, the problem requires assistance from Compaq
technical support. See “About This Guide” at the beginning of this book for
technical support phone numbers.

Optimizing Array Controller Performance
To increase the performance of your disk subsystem(s) under NetWare 4.x,
follow each of these steps before installing NetWare volumes or partitions.
■ If you selected a fault-tolerance option, such as mirroring or distributed
data guarding when using the Compaq System Configuration Utility,
do not select mirroring while using INSTALL.NLM. The faulttolerance capabilities of the SMART-2DH Controller provide
performance improvements and automatic data recovery features.
6-7
■ Novell recommends that you create volumes with a 64-KB block size
and that you use the Block Sub-Allocation feature of intraNetWare.
Using a large block size decreases the amount of RAM required to
mount the volume, while Block Sub-Allocation allows intraNetWare to
allocate disk space more efficiently.
■ Use of linear memory provides the best performance in the
intraNetWare environment. When you use the Compaq System
Configuration Utility to configure your server with intraNetWare, 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.

Installing the Operating System Drivers
Using the Compaq Drive Array Optimization
Utility (CPQDAOPT)
Compaq recommends that you use the Compaq Drive Array Optimization
Utility (CPQDAOPT.NLM) to optimize your drive arrays before creating
partitions. CPQDAOPT is a utility designed to assist you in optimizing
performance and can increase drive array performance by 20 to 40 percent.
This is accomplished by adjusting the size of the Hot Fix Redirection Area of
a partition to reduce the number of disk accesses. CPQDAOPT provides you
with a formula specific to your configuration. You must use this information
as you create a partition using INSTALL.NLM. If you installed
NetWare/intraNetWare using SmartStart, it is not necessary to run this utility.
Using CPQDAOPT On New NetWare/intraNetWare
Servers
Before you load CPQDAOPT on your new NetWare/intraNetWare server,
make sure you have followed the instructions for installing
NetWare/intraNetWare from CD found in the INSTALL.RDM file on Novell
SSD Disk 1.
: Back up existing data before applying new settings to data volumes.
NOTE
1. Start your NetWare/intraNetWare server.
2. Copy the CLIB.NLM and STREAMS.NLM files from the
NetWare/intraNetWare Installation CD-ROM (D:\NW410\BOOT or
D:\INTRANETWARE.312\________\C; where the line represents
eight underscores) to the server’s DOS partition before you begin
installation.
3. Start the NetWare/intraNetWare installation. When loading drivers, be
sure that you have the CPQDA386.DSK (version 3.10 or later) or
CPQARRAY.HAM driver loaded.
4. When the “Create NetWare Partition” option appears, use the Alt+Esc
key sequence to change to the console prompt and load CLIB:
load clib.nlm

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
and press Enter.
7. CPQDAOPT determines if it is possible to optimize the alignment of
data on the selected device. If so, it provides you with a formula for
determining the size of the Hot Fix Redirection Area you should select
when creating this partition. Make a note of the formula: even, odd,
and so on.
8. 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 from NetWare/intraNetWare 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.
9. Use the Alt+Esc keys to return to the NetWare/intraNetWare
installation process and select the option to create disk partitions. 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 number
that is even will work.
6-9
10. After the SYS volume is optimized and the NetWare/intraNetWare
files are installed, 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

7. You may receive a warning about changing the cache buffer size on
your server. In some cases, increasing the size of the cache buffers on a
NetWare/intraNetWare server may slow I/O performance.
8. If you must enlarge the cache buffer size and it takes the partition out
of optimal alignment, or if CPQDAOPT informs you that the existing
partition on a device is not optimally aligned, it is still possible to
configure the partition optimally.
a. Make a backup of the data on your server to avoid data loss.
b. Use INSTALL.NLM Disk Options, Partition Tables, and Change

Area using the formula provided by CPQDAOPT.
c. Recreate your volume(s).
d. Restore your data.
Software Drive Mirroring
with NetWare/intraNetWare
If you use drive mirroring fault tolerance, be aware that
NetWare/intraNetWare 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 fail and your data will
be lost.
6-11
To avoid this problem, you must mirror logical drives on separate arrays. Use
the Compaq Array Configuration Utility for NetWare/intraNetWare
(CPQONLIN.NLM) on Novell SSD Disk 3 to view the logical configuration
for the SMART-2DH Array Controller. Record which logical drives reside on
which arrays. When configuring NetWare/intraNetWare for drive mirroring,
select equally sized logical drives on different arrays.
IMPORTANT:
NetWare will not be able to warn you if you mirror logical
drives which share a physical drive because NetWare cannot distinguish the
individual physical drives. If you do not have at least two arrays, you should
not use NetWare drive mirroring.

Handling Disk Drive Failures
Although drive failures are not common, they may occur; 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-2DH Controller with hardware fault tolerance. An
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
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 backup procedures, in case of catastrophic failure.
If you discover a failed drive, perform the following steps:
■ 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 may be viewed using the SYSCON
utility (intraNetWare 3.12) or NWADMIN utility (NetWare 4.x).
■ Make sure that you have a recent backup. If the drive is part of a fault-
tolerant mirrored volume, or a hardware fault-tolerant volume, you will
be able to backup 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 sections below for replacing a drive for
your particular server configuration.
DOS Partitions and
NetWare/intraNetWare Fault Tolerance
NetWare/intraNetWare 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 backup source.

Page 81
If the failed drive contains a DOS partition, NetWare/intraNetWare will not
be able to access information on that partition. For example, files on the DOS
partition include STARTUP.NCF and Novell disk drivers. To prevent
NetWare/intraNetWare 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 drive
that failed 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 complete the following:
1. Power down your server.
2. Replace the failed drive.
3. Reboot the system with the Compaq System Configuration
Utility diskette.
6-13
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 megabytes.
7. Set the active partition to the DOS partition you just created.
8. Use the FORMAT command to format the DOS partition to include the
necessary files to make the partition bootable. For example:
FORMAT C: /s

SERVER.EXE
INSTALL.NLM
VREPAIR.NLM
MONITOR.NLM
CLIB.NLM
STREAMS.NLM
10. Copy the required disk drivers, LAN drivers, and utility NLMs that
should reside on the DOS partition from the Novell SSD.
11. Copy any other necessary information to the DOS partition and then
reboot your system. You are now ready to start your
NetWare/intraNetWare server. You may need to recreate your
STARTUP.NCF file.
Recovering Drives Configured for
Hardware Fault Tolerance
If you configure your SMART-2DH Array 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 done by observing the 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 that is of the same
capacity. For hot-pluggable drives, after you secure the drive in the
bay, the LEDs on the drive will all light once in an alternating pattern
to indicate that the connection was successful. The Online LED will
blink indicating that the controller has recognized the drive
replacement and begun the recovery process.
4. Power on the server, if applicable.

Page 83
5. The SMART-2DH Controller firmware will reconstruct 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 will blink. The controller will signal
that it has completed rebuilding the information on the drive by
lighting the Online LED.
6. NetWare/intraNetWare has no knowledge of a single physical drive
failure when using hardware-based fault tolerance; intraNetWare will
find that the data is still valid and accessible during the rebuilding
process.
Recovering Drives Configured for
NetWare/intraNetWare
Fault Tolerance
If you have chosen no fault tolerance for the drives connected to your
SMART-2DH Controller and have configured NetWare/intraNetWare
mirroring or NetWare/intraNetWare controller duplexing, use the following
procedure to recover the data after a drive failure:
1. Identify the failed physical drive that caused the
NetWare/intraNetWare device to be deactivated due to drive failure.
Record the device number and device name of the failed logical drive.
For example:
6-15
Device #1 (47000) Slot 1 Disk 1 NFT
The failure messages are recorded on the server console and also in the
server error log file, which may be viewed using the SYSCON utility
(3.12) or the NWADMIN utility (4.x). This information will be used
later to recreate 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
(step 1 above). 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:
NetWare 386 Partition 3 on Device #2 (47110)

Installing the Operating System Drivers
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. This is the
location is where the new physical drive must be inserted.
5. If the failed drive is hot-pluggable, skip to step 6. Otherwise, schedule
server down time, bring down the server, and power off the unit.
6. 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. Be sure that all cable connections are securely in place.
For replacements in a ProLiant server or storage system, after you
secure the drive in the bay, the LEDs on the drive will all light once in
an alternating pattern to indicate that the connection was successful. The
Online LED will turn 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 it is replacing.
7. Activate the replaced device. Use MONITOR.NLM Disk Information
option to select the device. Some versions of NetWare/intraNetWare
will cause a “device activate” to occur automatically when this option
is chosen. Other versions of NetWare/intraNetWare require manual
activation of the device by changing the operating status to active. A
console alert will be sent by the driver if attempts to reactivate the
failed logical drive are successful.
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. See
the section “Using CPQDAOPT on Existing NetWare/intraNetWare
Servers” in this chapter for more information about optimizing the
performance.
9. Use the INSTALL.NLM to delete and recreate the partition on the
repaired logical drive.

10. Return to the INSTALL.NLM Disk Options menu. If you are not
running intraNetWare SFT III or NetWare 4.x, you may 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. Use the Insert key to resynchronize this partition.
NetWare/intraNetWare requires you to resynchronize before deleting
the partition. Allow INSTALL to resynchronize this partition. You may
receive warning messages that the selected partition contains an
already-defined volume and ask if you want to rename the volume.
Select No and press Esc. Since you plan to delete this partition, there is
no reason to salvage the volume. You should be able to proceed with
deleting the partition table.
11. Using 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 should have been recorded in step 1 above. For
example:
Device #1 (47000) Slot 1 Dsk 1 NFT
Select the Delete Partition option. INSTALL may show several error
messages. Do not update any Volume Definition Table information
because you will delete this partition anyway. Continue until the
partition on this device 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. It
may be MONITOR.NLM, so you will need to unload MONITOR and
any other NLMs that have the partition locked. After you have
recreated the partition and volume information, reload those NLMs.
12. Recreate the partition on the same logical drive.
13. Return to the Disk Options Mirroring menu. Select the NetWare 386
Partition number that was previously mirrored. This partition was
recorded in step 2 above.

14. Press Insert for a list of partitions available to remirror. Select the
partition associated with the device (step 1) that was repaired. This step
causes NetWare/intraNetWare to begin resynchronizing the mirrored
partitions.
15. A console message indicates successful completion of the
resynchronization step.
Recovering Drives Configured for No
Fault Tolerance
If you have 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 due to drive failure. Record the device number and device
name of the failed logical drive. For example:
Device #1 (47000) Slot 1 Dsk 1 NFT
The failure messages are recorded on the server console. They are also
recorded in the server error log file, which may be viewed using the
SYSCON utility (NetWare 3.12) or the NWADMIN utility (intraNetWare).
This information will be used later to recreate a valid partition.
6-19
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.
Note that 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.

Installing the Operating System Drivers
For hot-pluggable drives, after you secure the drive in the bay, the LEDs
on the drive will all light once in an alternating pattern to indicate that
the connection was successful. The Online LED will turn 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 it
is replacing.

4. It may be possible to use the INSTALL.NLM option Change Hot Fix to
determine the number of Hot Fix Redirection blocks set up for this
partition. Otherwise, see the section “Using CPQDAOPT on Existing
NetWare/intraNetWare Servers” in this chapter for more information
about optimizing the performance.
: Even though the logical drive may have a valid partition table, the
NOTE
data on this logical drive is NO LONGER VALID. Some data may appear valid
because the failed physical drive is 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 recreate a new partition on the logical drive.
5. Return to the INSTALL.NLM Disk Options menu. Select the Partition
Tables Option. At this point the driver should reactivate the failed
logical drive. A console alert will be sent by the driver if attempts to
reactivate the failed logical drive are successful. In the INSTALL.NLM
Available Disk Drives menu, select the previously failed logical drive,
which has now been repaired. The device information should have
been recorded in step 1 above. For example:
Device #1 (47000) Slot 1 Dsk 1 NFT
Select the Delete Partition option. INSTALL may present several error
messages. Delete the volume associated with this partition. Do not
update any Volume Definition Table information because you will
delete this partition. Continue until the partition on this device 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. It may be
MONITOR.NLM, so you will need to unload MONITOR and any other
NLMs that have the partition locked. After you have recreated the
partition and volume information, reload these NLMs.
6. Recreate the partition on the same logical drive.
7. Recreate and mount the volume.
8. Locate the recent backup media and restore the data to this server
volume.
