What You Need to Know Before You Begin
You should be familiar with computer hardware, data storage, Redundant Array of
Independent Disks (RAID) technology, and the input/output (I/O) technology—SAS—used
You should also be familiar with Direct Attached Storage (DAS) and Storage Area Network
(SAN) concepts and technology.
Terminology Used in this Guide
Because you can use your HostRAID controller to manage data storage in a variety of
configurations from DAS to SAN, the generic term “storage space” is used to refer to
controller(s) and disk drives being managed with Adaptec Storage ManagerTM or the other
utilities described in this Guide.
Many of the terms and concepts referred to in this Guide are known to computer users by
multiple names. This Guide uses these terms:
●
●
●
Controller (also known as adapter, board, or card)
Disk drive (also known as hard disk, hard drive, or hard disk drive)
Array (also known as a container or logical drive)
Note: The Adaptec Storage Manager User’s Guide refers to arrays as logical drives. Why?
Your HostRAID controller creates arrays, which your operating system (and Adaptec Storage
Manager) recognizes as logical drives.
How to Find More Information
You can find more information about your HostRAID controller and the software and utilities
included with it by referring to these documents:

About Adaptec Storage Manager
Adaptec Storage Manager is a full-featured software application that helps you build a storage
space for your online data, using HostRAID controllers and disk drives.
With Adaptec Storage Manager, you can group disk drives into logical drives and build in
redundancy to protect your data and improve system performance.
You can also use Adaptec Storage Manager to monitor and manage all the controllers and disk
drives in your storage space from a single location.
When Adaptec Storage Manager is installed on a computer, the Adaptec Storage Manager agent
is also installed automatically. The agent is like a service that keeps your storage space running.
It’s designed to run in the background, without user intervention, and its job is to monitor and
manage system health, event notifications, tasks schedules, and other on-going processes on
that system. It sends notices when tasks are completed successfully, and sounds an alarm when
errors or failures occur on that system.
The agent uses less memory than the full application. If your storage space includes systems
that won’t be connected to monitors (and therefore won’t require the user interface), you can
choose to run the agent only on those systems instead of the full application. For more
information, refer to the Adaptec Storage Manager User’s Guide or online Help.
Installing Adaptec Storage Manager
Adaptec Storage Manager is included on the Adaptec Storage Manager Installation CD. For
installation instructions, refer to the Adaptec Storage Manager User’s Guide, also included on
the Adaptec Storage Manager Installation CD.
About the HRCONF Command Line Utility
HRCONF (HostRAID Configuration Utility) is a command line utility that you can use to
perform some basic array and configuration management functions.
With HRCONF, you can:
●
●
●
Create and delete logical drives
Modify and copy configuration settings
Recover from disk drive failures and troubleshoot
Installing and Using the Command Line Utility on page 76, describes how to use HRCONF.

About the ARC Utility
The Adaptec RAID Configuration (ARC) utility is a BIOS-based utility that you can use to
create and manage controllers, disk drives and other devices, and arrays. The ARC utility
comprises these tools:
●
Array Configuration Utility (ACU)—For creating and managing arrays, and initializing
and rescanning disk drives.
●
●
SerialSelect Utility—Used to change device and HostRAID controller settings.
Disk Utilities—For formatting or verifying disk drives.
The ARC utility is included in your controller’s BIOS. For more information, see Using the
Note: The ARC utility is primarily intended for pre-operating system installation
configuration.
About the AFU
The Adaptec Flash Utility (AFU) is a text-based DOS utility that you can use to update, save, or
verify your HostRAID controller’s firmware BIOS and Non-Volatile Random Access Memory
(NVRAM).
Caution: Although the AFU contains safeguards to prevent you from accidentally damaging
your HostRAID controller’s flash contents, it is still important to use the AFU carefully and
!
correctly to avoid rendering your HostRAID controller inoperable. Adaptec recommends that
only advanced users familiar with working in DOS use the AFU.
Which Utility Should I Use?
To create a bootable array, Adaptec recommends that you use the BIOS-based ARC utility
(see above).
For all subsequent storage management tasks, Adaptec recommends that you install and use
user interface (GUI), it is the easiest to use and offers the widest range of management
functions.

Troubleshooting Checklist
If you encounter difficulties installing or using your HostRAID controller, check these items
first:
●
With your computer powered off, check the connections to each disk drive, the power
supply, the LED connector, and so on.
●
●
Try disconnecting and reconnecting disk drives from the HostRAID controller.
Check that your HostRAID controller is installed in a compatible expansion slot (PCI-X).
●
●
●
Ensure that your HostRAID controller is firmly seated and secured in the PCI-X expansion
slot.
If your HostRAID controller is not detected during system boot, try installing it in a

Recovering from a Disk Drive Failure
This section explains how to recover when a disk drive fails:
●
●
●
●
●
If the array was protected by a hot spare (see next section).
Note: Adaptec Storage Manager uses the term logical drives when referring to arrays
Failed Disk Drive Protected by a Hot Spare
When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is
automatically incorporated into the array and takes over for the failed drive.
To recover from the failure:
●
Remove and replace the failed disk drive (following manufacturer’s instructions).
Chapter 11: Solving Problems
●
51
Failed Disk Drive Not Protected by a Hot Spare
When an array is not protected by a hot spare, if a disk drive in that array fails, remove and
replace the failed disk drive. The controller detects the new disk drive and begins to rebuild the
array.
If the controller fails to rebuild the array, check that the cables, disk drives, and controllers are
properly installed and connected. Then, if necessary, use Adaptec Storage Manager to rebuild
the array. For instructions, refer to the Adaptec Storage Manager User’s Guide or online Help.
Failure in Multiple Arrays Simultaneously
If there’s a disk drive failure in more than one array at the same time (one failure per array),
and the arrays have hot spares protecting them, the controller rebuilds the arrays with these
limitations:
●
●
A hot spare must be of equal or greater size than the failed disk drive it’s replacing.
Failed disk drives are replaced with hot spares in the order in which they failed. (The array
that includes the disk drive that failed first is rebuilt first, assuming an appropriate hot
spare is available—see bullet above.)
If there are more disk drive failures than hot spares, see Failed Disk Drive Not Protected by a Hot
Spare in previous section.
Disk Drive Failure in a RAID 0 Array
Because RAID 0 volumes do not include redundancy, if a disk drive fails in a RAID 0 array, the
data can’t be recovered.
Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if
available).
Multiple Failures in the Same Array
If more than one disk drive fails at the same time in the same RAID 1 array, the data can’t be
recovered.
Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if
available).
In some instances, RAID 10 arrays may survive multiple disk drive failures, depending on
which disk drives fail. For more information, refer to the Adaptec Storage Manager User’s Guide
or online Help.

Appendix A: Introduction to SAS
●

Terminology Used in This Chapter
For convenience, SAS HostRAID controllers are referred to generically in this chapter as SAS
cards. HBAs, HostRAID controllers, disk drives, and external disk drive enclosures are referred
to as end devices and expanders are referred to as expander devices.
For convenience, this chapter refers to end devices and expander devices collectively as SAS
devices.
What is SAS?
Legacy parallel SCSI is an interface that lets devices such as computers and disk drives
communicate with each other. Parallel SCSI moves multiple bits of data in parallel (at the same
time), using the SCSI command set.
SAS is an evolution of parallel SCSI to a point-to-point serial interface. SAS also uses the SCSI
command set, but moves multiple bits of data one at a time. SAS links end devices through
direct-attach connections, or through expander devices.
SAS cards can typically support up to 128 end devices and can communicate with both SAS
and SATA devices. (You can add 128 end devices—or even more—with the use of SAS
Adaptec recommends that you not combine SAS and SATA disk drives within the same array or
logical drive. The difference in performance between the two types of disk drives may adversely
affect the performance of the array.
Data can move in both directions simultaneously across a SAS connection (called a link—see
next section). Link speed is 600 MB/sec in full-duplex mode. A SAS card with eight links has a
maximum bandwidth of 4800 MB/sec in full-duplex mode.
Although they share the SCSI command set, SAS is conceptually different from parallel SCSI
physically, and has its own types of connectors, cables, connection options, and terminology, as
described in the rest of this chapter.
How Do SAS Devices Communicate?
SAS devices communicate with each other through links. A link is a physical connection
between two phys.
Appendix A: Introduction to SAS
●
54
As shown in the following figure, SAS devices contain ports which contain phys (see next
section), and each phy contains one transmitter and one receiver—one transceiver. A phy can
belong to one port only.

What’s a Phy?
Phys are part of the physical communication connection between SAS devices. Each phy
contains a transceiver that sends data back and forth between SAS devices.
When a connection is formed between two end devices, a link is established from a phy in one
port to a phy in the other port. As shown in the figure above, a wide port can support multiple
independent links simultaneously.
SAS cables physically connect one or more phys on one SAS device to one or more phys on
another SAS device.
What’s a SAS Port?
Note: Because the physical link between SAS devices is from phy to phy, rather than port
to port, a “port” is more of a virtual concept, different from what is normally considered a
port on other types of RAID controllers and storage devices.
A port is one or more phys. A narrow port contains one phy. A wide port typically contains four
phys.
same SAS address.
SAS card port options vary. A SAS card with four phys could be configured with one wide port,
with two wide ports that comprise two phys, or with four narrow ports each containing one
phy. (A wide port with four phys is referred to as a 4-wide or 4x port.)
Appendix A: Introduction to SAS
●
55
What’s a SAS Address?
Each SAS port is identified with a unique SAS address, which is shared by all phys on that port.
For example, a SAS disk drive might have two narrow ports. Each port has one unique SAS
address. The single phy in each port uses its port’s SAS address.
In another example, a SAS device might have one 4-wide port. That port has one SAS address,
which is shared by all four phys in the port.
Unlike SCSI devices and SCSI IDs, SAS devices self-configure their SAS addresses. User
intervention is not required to set SAS addresses, and SAS addresses cannot be modified.
What’s a SAS Connector?
A SAS connector is the physical plug or receptacle that you see on a SAS device. It supports the
power and signal line cable. It’s what you plug a SAS cable into, or the end of the SAS cable
that’s being plugged in.
A connector is what forms physical links between phys. Some SAS connectors can support
multiple links. The number of links a SAS connector can support is referred to as its width.
Narrow connectors support a single link; wide connectors support up to four links.
A single SAS device may have one or more connectors. A single SAS connector may help form
4-wide internal SAS connector forms links with four independent disk drives.)
What do SAS Cables Look Like?
Internal SAS cables are narrower than internal parallel SCSI cables. The connectors vary in size
depending on the number of links they support, from single link connectors to 4-wide (or
larger) connectors. Internal fan-out cables let you attach four disk drives to a single 4-wide
connector.
How are Disk Drives Identified in SAS?
numbers in this format:
XX:YY:ZZ
where XX is the disk drive count number, YY is the enclosure number, and ZZ is the slot
number (within the enclosure). If the disk drive is not installed in an enclosure, a double
dashes (--) appear instead of YY and ZZ (for instance, 01:--:--).
In parallel SCSI, XX is the disk drive’s channel number, YY is the target number, and ZZ is the
logical unit number (LUN).
What are the SAS Connection Options?
You can connect end devices to each other through direct cable connections and through
create large configurations.
Appendix A: Introduction to SAS
●
56
Direct-attach Connections
In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card
with SAS cables. One disk drive is attached to one SAS connector with one SAS cable (or
multiple disk drives are attached to one SAS connector with one fan-out cable). The figure on
page 25 shows an example of direct-attach connections.
The number of direct-attached disk drives is limited to the number of phys supported by the
Backplane Connections
In a backplane connection, disk drives and SAS cards are attached to and communicate with
connections.
The number of end devices is limited to the number of slots available on the backplane. For
example, the Adaptec S50 enclosure, which contains an expander, is a backplane connection
that supports up to 12 SAS or SATA disk drives.
Some backplanes support daisy-chain expansion to other backplanes. For example, you can
daisy-chain (connect one to the next) up to nine Adaptec S50 enclosures to a single SAS card in
a host system.
SAS Expander Connections
A SAS expander device literally expands the number of end devices that you can connect
large configurations of SAS end devices, including SAS cards and SAS and SATA disk drives.
With expander devices, you can build large and complex storage topologies.
There are two types of SAS expanders: fanout expanders and edge expanders. Each performs a
different role in a storage system. (For more information about how SAS expanders work, refer
to the STA Web site at www.scsita.org.)
You can connect up to 128 SAS ports to an edge expander. (A single edge expander can
therefore support up to 128 SAS addresses.)
You can connect up to 128 edge expanders to a fanout expander.
You can use only one fanout expander in any single SAS domain (a topology of SAS—and
possibly SATA—end devices and expander devices). A single SAS domain can therefore
comprise up to 16,384 SAS ports (and therefore up to 16,384 SAS addresses).
Appendix A: Introduction to SAS

How is SAS Different from Parallel SCSI?
In summary, although SAS and parallel SCSI both use the SCSI command set, how they move
data from one place to another is very different. To support point-to-point serial data
transport, SAS introduces new types of connectors, cables, connection options, and
terminology.
Generally speaking, SAS is faster and more flexible than parallel SCSI, and provides more
options for building your storage space. SAS lets you mix SAS and SATA disk drives together,
and lets you connect many, many more devices.
The following table describes many of the main differences between the two interfaces.

RAID Technology Overview .................................................................................................. 59
When you create arrays (or logical drives), you can assign a RAID level to protect your data.
Each RAID level offers a unique combination of performance and redundancy. RAID levels
also vary by the number of disk drives they support.
This appendix describes the RAID levels supported by your HostRAID controller, and provides
a basic overview of each to help you select the best level of protection for your data storage.
Appendix B: Understanding RAID
●
59
RAID Technology Overview
RAID is the technology of grouping several physical drives in a computer into an array that you
can define as one or more logical drives. Each logical drive appears to the operating system as a
single drive. This grouping technique greatly enhances logical-drive capacity and performance
beyond the physical limitations of a single physical drive.
When you group multiple physical drives into a logical drive, the HostRAID controller can
transfer data in parallel from the multiple drives in the array. This parallel transfer yields data-
transfer rates that are many times higher than with non-arrayed drives, enabling the system to
better meet the throughput (amount of data processed in a given amount of time) or
productivity needs of the multiple-user network environment.
The ability to respond to multiple data requests provides not only an increase in throughput,
but also a decrease in response time. The combination of parallel transfers and simultaneous
responses to multiple requests enables disk arrays to provide a high level of performance in
network environments.
Understanding Drive Segments
A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk
drive can include both RAID segments (segments that are part of an array) and available
segments. Each segment can be part of only one logical device at a time. If a disk drive is not
part of any logical device, the entire disk is an available segment.
Stripe-unit Size
With RAID technology, data is striped across an array of physical drives. This data-distribution
scheme complements the way the operating system requests data.
The granularity at which data is stored on one drive of the array before subsequent data is
stored on the next drive of the array is called the stripe-unit size.
You can set the stripe-unit size to 16, 32, or 64 KB. You can maximize the performance of your
HostRAID controller by setting the stripe-unit size to a value that is close to the size of the
system I/O requests. For example, performance in transaction-based environments, which
typically involve large blocks of data, might be optimal when the stripe-unit size is set to 32 or
64 KB. However, performance in file and print environments, which typically involve multiple
small blocks of data, might be optimal when the stripe-unit size is set to 16 KB.
The collection of stripe units, from the first drive of the array to the last drive of the array, is
called a stripe.
Selecting a RAID Level and Tuning Performance
Disk arrays are used to improve performance and reliability. The amount of improvement
depends on the application programs that you run on the server and the RAID levels that you
assign to the logical drives.
Each RAID level provides different levels of fault-tolerance (data redundancy), utilization of
physical drive capacity, and read and write performance. In addition, the RAID levels differ in
regard to the minimum and maximum number of physical drives that are supported.

Physical drive utilization, read performance, and write performance depend on the number of
drives in the array. Generally, the more drives in the array, the better the performance.
RAID 0 (Non-RAID Arrays)
An array with RAID 0 includes two or more disk drives (maximum twelve) and provides data
striping, where data is distributed evenly across the disk drives in equal-sized sections.
RAID 0 arrays do not maintain redundant data, so they offer no data protection. However,
compared to an equal-sized group of independent disks, a RAID 0 array provides improved
I/O performance.
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an
array with two 250 GB disk drives and two 400 GB disk drives can create a RAID 0 drive
segment of 250 GB, for a total of 1000 GB for the volume, as shown in the following figure.

RAID 1 Arrays
A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the
same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays
provide improved performance, with twice the read rate and an equal write rate of single disks.
However, capacity is only 50 percent of independent disk drives.
If the RAID 1 array is built from different-sized disk drives, the free space, drive segment size is
the size of the smaller disk drive, as shown in the following figure.

RAID 10 Arrays
A RAID 10 array is built from two or more equal-sized RAID 1 arrays. Adaptec RAID
controllers support a maximum number of 48 disk drives in a RAID 10 array.
Data in a RAID 10 array is both striped and mirrored. Mirroring provides data protection, and
striping improves performance.
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an
array with two 250 GB disk drives and two 400 GB disk drives can create two mirrored drive
segments of 250 GB, for a total of 500 GB for the array, as shown in the following figure.

Introduction to the ARC Utility
The ARC utility comprises these tools:
●
The Array Configuration Utility (ACU)—Used to create, configure, and manage arrays,
and initialize and rescan disk drives.
●
●
SerialSelect Utility—Used to change device and HostRAID controller settings.
Running the ARC Utility
All the tools within the ARC utility are menu-based and instructions for completing tasks
display on-screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on
your keyboard.
To run the Utility:

Select the disks for the new array, then press Insert. To deselect any disk, highlight the disk,
then press Delete.
Press Enter when all disks for the new array are selected. The Array Properties menu
displays.
Assigning Array Properties
Once the array is created and its properties are assigned, you cannot change the array
Appendix C: Using the ARC Utility
●
64
To assign properties to the new array:
1
In the Array Properties menu, select an array type, then press Enter.
Only the available array types, RAID 0, 1, and 10 are displayed. RAID 0 and 1 requires two
to four drives. RAID 10 requires a minimum of four disk drives.
2
3
Optional: Type a label of no more than 15 characters for the array, then press Enter.
For RAID 0, select the desired stripe size. Available stripe sizes are 16, 32, and 64 KB
(default).
Note: It is recommended that you do not change the default.
4
The options under Create RAID Via allows you to select between the different creation
methods for RAID 0, 1, and 10. The following table gives examples of when each is
appropriate.
RAID

RAID 0
RAID 0
Quick Init
Creating a RAID 0 on new drives.
Migrate
Build
Creating a RAID 0 and you want to preserve data on an existing
drive. You will be asked to select the source drive. The contents
of the source drive are preserved and any data on the new drive
is lost.
RAID 1
Creating a RAID 1 and you want to preserve data on an existing
drive. You will be asked to select the source drive. The contents
of the source drive are preserved and any data on the new drive
is lost.
RAID 1,
10

Creating a RAID 1 or 10 on new drives, or when you want to
ensure that the new array contains no existing data.
RAID 1,
10
Quick Init
Fastest way to create a RAID 1 or 10. Appropriate when using a
new drive.
Note:
●
Before adding a new drive to an array, back up any data contained on the new drive.
Otherwise, all data will be lost.
●
Only disk drives that were previously configured as simple volumes can be used for
RAID 0 or 1 migration when the single/source drive has data on it. See Configuring
●
●
If you stop the build or clear process on a RAID 1 from ACU, you can restart it by
pressing Ctrl+R.
A RAID 1 and 10 created using the Quick Init option may return some data
miscompares if you later run a consistency check. This is normal and is not a cause for
concern.
●
●
●
If you stop the migration process on a RAID 0, you can restart it by pressing Ctrl+R.
To modify the Write Cache setting for an array, press Ctrl+W.
The ACU allows you to use drives of different sizes in a RAID 1. However, during a
build operation, only the smaller drive can be selected as the source drive.
Appendix C: Using the ARC Utility
●
65
●
●
When migrating from single volume to RAID 0, migrating from a larger drive to a
smaller drive is allowed. However, the destination drive must be at least half the
capacity of the source drive.
It is not recommend that you migrate or build an array on Windows dynamic disks
(volumes), as it will result in data loss.

By replacing a failed drive of a RAID 1 array with a new drive, you can rebuild to get the array
to Optimal status and assume fault tolerance. You can perform a rebuild in the following ways:
Note: If no spare exists and a hard disk drive fails, you need to create a spare before you
rebuild.
●
System Shutdown Rebuild
You can shut down the system and replace the failed drive with a new one (of equal or
greater capacity). When the system is booted, you can assign the new drive as a spare, and
this will start the Rebuild task. All the data from the good drive is copied to the new one,

Using the AFU for DOS
In this chapter...
This chapter describes how to use the Adaptec Flash Utility (AFU), a text-based DOS utility
that you can use to update, save, or verify the HostRAID controller’s firmware BIOS.
Caution: Although the AFU contains safeguards to prevent you from accidentally damaging
your HostRAID controller’s flash contents, it is still important to use the AFU carefully and
!
correctly to avoid rendering your HostRAID controller inoperable. Adaptec recommends that
only advanced users familiar with working in DOS use the AFU. For more information, see
Appendix D: Using the AFU for DOS
●
71
Introduction
The AFU is a DOS utility used to update, save, or verify the HostRAID controller’s firmware
BIOS.
The AFU is easy to use and contains safeguards to prevent you from accidentally damaging the
HostRAID controller’s flash contents. Still, you must be careful to use the AFU correctly,
otherwise, you could render the HostRAID controller inoperable.
The AFU is used to:
●
Update—Updates all the flash components on a HostRAID controller with the flash image
data from a User Flash Image (UFI) file.
The AFU updates the HostRAID controller’s flash by reading UFI files and writing them to
the controller’s flash components.
Note: The UFI includes the HostRAID controller’s type, thereby ensuring that the AFU
uses the correct file.
●
●
Save—Updates and verifies the BIOS image of the controller.
Verify—Reads the contents of a HostRAID controller’s flash components and compares it
to the contents of the specified UFI file.
●
●
Version—Displays version information about a HostRAID controller’s flash components.
List—Lists all supported HostRAID controllers detected in your system.
System Requirements
The requirements for AFU are as follows:
●
MS–DOS version 5.0 or later. It cannot run from a DOS command prompt window under
any version of Windows.
Note: You cannot create a bootable floppy using Windows 2000.
●
At least 8 MB of extended memory.
Compatibility
The AFU has the following compatibility issues:
●
Supports HIMEM.SYS and is compatible with other DOS drivers running under
HIMEM.SYS (for example, SMARTDRV.SYS and SETVER.SYS).
●
Does not support DOS extenders installed in memory, such as EMM386.SYS and
DOS4GW.
Running the AFU from the GUI
The easy way to run the AFU is to use its GUI. If you prefer to run the AFU from the command
Appendix D: Using the AFU for DOS
●
72
To access the AFU:
1
Shut down your operating system and reboot to DOS from a bootable MS-DOS floppy
disk or from a DOS partition on a bootable drive. (You can use the drive connected to the
HostRAID controller you are updating.)
Note: When updating the HostRAID controller flash, controller activity is not possible.
Before you can use the HostRAID controller again, complete the flash operation and restart
the computer.
2
3
At the DOS command prompt (typically A:\>) type AFU,then press Enter.
The AFU’s main menu is displayed.
Select Select Controllers, then select the Adaptec HostRAID controllers to be flashed.
When selecting a single controller, the system automatically selects it. When selecting
multiple controllers, use the spacebar, then press Enter.
4
Select Select an Operation and choose one of the available options, then follow the
on-screen instructions.
Running the AFU from the Command Line
At the DOS command prompt (typically A:\>), type AFUfollowed by a command and any
switches. The AFU processes the command, prompts you to insert additional floppy disks as
needed, exits, and reports success or an error message code. The following available commands
are summarized in alphabetical order.
HELP
The HELPcommand displays a summary of AFU functions and command switches.
Examples
The following are examples of command syntax that will work to get help:
A:\> AFU HELP
A:\> AFU /?
LIST
The LISTcommand displays the AFU-supported HostRAID controllers installed on your
computer. Use this command to see which HostRAID controllers are installed, or to identify
the ID numbers assigned to each physical controller.
You do not have to restart the computer after completing this command.
Example
This example shows a typical system response to a LISTcommand:

Appendix D: Using the AFU for DOS
●
73
SAVE
The SAVEcommand saves the contents of a HostRAID controller’s flash in a UFI file. The name
of the UFI file is based on the HostRAID controller type and cannot be changed.
Command Syntax
The command syntax for the SAVEcommand is as follows:
AFU SAVE [/C<Controller ID>] [/D <UFI File Path>]
Command Switches
The following switches are available:
●
/C <Controller ID> is one or more HostRAID controller IDs representing the set of
controllers on which to perform the specified command. The default is 0, which means
that if the computer has multiple HostRAID controllers, the AFU defaults to controller 0
unless you specify otherwise.
You can specify a single HostRAID controller ID, for example:
/C 0
multiple IDs separated by commas, for example:
/C 0,2
or ALLto indicate all HostRAID controllers.
Note: If you are using multiple HostRAID controllers, you must specify the controller
you want by using the /C switch; otherwise, the AFU displays an error message and
exits. You cannot select ALL HostRAID controllers when specifying SAVE.
●
/D <UFI File Path> specifies the path (drive and directory) where the UFI files are located.
If you do not specify the /D switch, the AFU looks for, or creates, UFI files in the default
location.
Note: You cannot specify the name of a UFI file, only its path. UFI filenames are
predefined, based on the HostRAID controller type.
Examples
In the following example, the AFU saves flash contents from HostRAID controller 0 to a UFI
file in the current default drive and directory:
A:\> AFU SAVE /C 0
In the following example, the AFU saves flash contents from Controller 1 to a UFI file in
C:\UFI_FILES.
A:\> AFU SAVE /C 1 /D C:\UFI_FILES
Appendix D: Using the AFU for DOS

If you have multiple HostRAID controllers only—At the DOS prompt, type afu list,
then press Enter.
This command displays the Adaptec SAS HostRAID controllers in your system. Note the
HostRAID controller number for the controller you want to update; you may need it in
Step 6 to perform the update.
You can update the flash using any of the following alternatives:
a
b
Updating the Flash on a Single HostRAID Controller—To flash the firmware on a
single HostRAID controller, type:
afu update /C <controller_number>
Where controller_numberis the number of the controller whose firmware you are
updating. For example, to upgrade Controller 0, type:
afu update /C 0
Updating the Flash on Multiple Controllers—To flash the firmware on multiple
HostRAID controllers, type:
afu update /C <controller_number_a>,<controller_number_b>
Where <controller_number_a>and <controller_number_b>are the number of one
of the Adaptec HostRAID controllers whose firmware you are updating.
To upgrade HostRAID controllers 0, 2, and 3 for example, type:
afu update /C 0, 2, 3
c
Updating the Flash on All HostRAID Controllers Simultaneously—To flash the
firmware on all HostRAID controllers, type:
afu update /C all
Note: The UFI file identifies the appropriate HostRAID controllers, so you do not
have to worry about flashing the wrong controller.
7
The AFU prompts you to put in the first firmware disk.
When it detects that the disk is in the drive, the AFU reads the part of the firmware image
contained on the first disk.

When prompted, remove the first firmware disk and insert the second firmware disk.
Safety Information
E
To ensure your personal safety and the safety of your equipment:
●
●
Keep your work area and the computer clean and clear of debris.
Before opening the system cabinet, unplug the power cord.
Electrostatic Discharge (ESD)
Caution: ESD can damage electronic components when they are improperly handled, and
can result in total or intermittent failures. Always follow ESD-prevention procedures when
removing and replacing components.
!
To prevent ESD damage:
●
●
●
●
Use an ESD wrist or ankle strap and ensure that it makes skin contact. Connect the
equipment end of the strap to an unpainted metal surface on the chassis.
If a wrist strap is not available, ground yourself by touching the metal chassis before
handling the controller or any other part of the computer.
Avoid touching the controller against your clothing. The wrist strap protects components
from ESD on the body only.
Handle the controller by its bracket or edges only. Avoid touching the printed circuit board
or the connectors.
●
●
Put the controller down only on an antistatic surface such as the bag supplied in your kit.
If you are returning the controller to Adaptec, put it back in its antistatic bag immediately.

Glossary
A
activity
ACU
Array Configuration Utility. An application used to create, configure, and manage arrays from the
controller’s BIOS or MS-DOS.
array
A logical disk created from available space and made up of one or more segments on one or more physical
disks. Arrays are typically used to provide data redundancy or enhanced I/O performance. See volume,
array initialization
ATA
AT Bus Attachment. Standard parallel interface to IDE hard disks typically used in desktop computers and
some entry-level servers. Serial ATA (SATA), is a successor to parallel ATA, which is sometimes referred to
as PATA.
available space/segment
Unused space on a configured disk from which logical devices (arrays) are created. When an array is
deleted, the space that it used is returned to the available space pool.
B
background consistency check
Option that forces the controller to constantly check all portions of disks used by all arrays to see if the disks
bad segment
Segment that is in an unknown state.
bootable array
Array configured as the boot device.
Glossary
●
89
build
Background initialization of a redundant array. The array is accessible throughout. RAID 1 copies the
bus
C
cache
Fast-access memory on the controller that serves as intermediate storage for data that is read from, or
written to, drives.
capacity
Total usable space available in megabytes or gigabytes.
channel
Any path, or bus, used for the transfer of data and the control of information between storage devices and a
RAID controller. For SATA channels, each channel has a single drive capacity.
check point
A feature that enables you to exit the ACU when an operation is in progress and be able to continue without
interruption. The driver then resumes the operation from where the BIOS left off and the BIOS resumes the
operation where the driver left off.
chunk
clear
Foreground initialization of a fault-tolerant array. A clear operation zeros all blocks of the array. The array
is not accessible until the clear task is complete.
concatenation
Joining of physical or logical drives in sequential order.
configure
Process of preparing a disk for use by the controller. When a disk is configured, the controller records the
RAID signature on the disk.
configured array
An array that is ready for data reads and writes. Arrays can be configured by build or clear.
consistency check command
Command that reads all the blocks of a RAID 1 to determine if the blocks are consistent. Any inconsistent
blocks are fixed.
D
dead partition
degraded
A redundant (for example, a RAID 1) array in which one or more members have failed. The data is intact
but redundancy has been compromised. Any further failure would cause the array to fail and result in data
loss.
disk
Physical disk drive. Randomly accessible, rewriteable data storage device. Also called hard disk.
Glossary
●
90
disk ID
Unique disk identifier that consists of the channel number, SATA ID. For example, (channel:ID:LUN)
drive LED
Disk indicator LED that illuminates during read or write operations.
E
event
Notification or alert from the system, indicating that a change has occurred.
event log
File used to maintain information about prior controller activities or errors.
event notification
Process for transmitting events.
F
failed
State of a nonredundant array that has suffered a single drive failure, or a redundant array that has suffered
multiple drive failures. A failed array is inaccessible and data is lost.
fault-tolerant array
Refers to an array that can continue to function after a disk drive failure without loss of data. Fault tolerant,
foreign disk
Disk that has previously been configured on another Adaptec RAID controller. The RAID signature on the
disk allows the RAID controller to identify whether or not the disk was configured on the controller it is
currently connected to.
H
hard disk drive
hot spare
A spare hard disk that automatically replaces a failed hard disk on any array associated with any HBA.
hot swap
To remove a component from a system, and install a new component while the power is on and the system
is running.
I
impacted
An impacted array is one which has been created but for some reason the initial build operation did not
complete. All member drives are present and operational, and all data written to the array is protected. To
optimize the array, run a Verify with Fix Task.
initialize
Glossary
●
91
L
legacy disk
Disk that contained a valid partition table when connected to the controller. The controller manages the
disk as a legacy disk array where there is a one-to-one logical-to-physical mapping of array to disk.
logical device
Volume comprised of space from one or more physical drives and presented to the operating system as if it
were a single storage unit.
low-level format
Process performed by the drive firmware that completely cleans any data off the hard disk.
M

monitoring
Process of receiving, displaying, and logging system events.
N
Native Command Queuing
Allows disk drives to arrange commands into the most efficient order for optimum performance.
O
offline array
Array that can no longer be accessed.
optimal
The state of an array when it is fully operational. For redundant arrays, the entire array is protected.
P
partition
A section of a disk storage device created by the operating system disk management program, in which data
and/or software programs are stored. Computers have a primary operating system partition that contains
the special files needed to boot the computer. Each operating system partition is assigned a unique drive
letter, such as C or D. A single disk device can have multiple partitions.
phantom object
Object that represents a component that cannot be configured by the controller management software; for
example, a missing drive.
Q
quick init
An array configured using the Quick Init option is available immediately, with no on-going background
controller activity. All data written to an array that has been quick configured is protected.

R
RAID
Redundant Array of Independent Disks (alternative definition Redundant Array of Inexpensive Disks).
RAID 0
A single-level array consisting of two or more equal-sized segments residing on different disks. RAID 0
distributes data evenly across its respective drives in equal-sized sections called stripes. RAID 0 arrays are
not redundant.
RAID 1
Single-level array consisting of two equal segments residing on two different drives. Provides redundancy
RAID 10
Spanned array consisting of two or more equal-sized RAID 1 arrays. Provides redundancy by striping and
mirroring. Mirroring provides data protection, and striping improves performance. See mirrored array/
RAID signature
The area on each disk reserved for use by the RAID controller.
RAID volume
Concatenates two or more arrays of the same type.
rebuild
Background regeneration of redundant data on a RAID 1.
redundant
The ability of an array to maintain operability when one or more hardware failures occur. RAID 1 is
redundant. In the event of a drive failure, redundant arrays can be restored to normal operation by
replacing the failed drive and rebuilding the array.
rescan
Process of updating the current screen to show all currently available resources.
S
Serial ATA (SATA)
A successor to ATA that uses a serial, instead of parallel, interface.
simple volume
A volume made up of disk space from a single disk. It can consist of a single region on a disk, or
concatenated multiple regions of the same disk.
single-level array
snapshot
Instantaneous read-only copy of an array at a precise point in time.
spanned volume
A simple volume that spans two or more drives.
stripe
Contiguous set of data distributed across all the disks in an array. A striped array distributes data evenly
across all members in equal-sized sections called stripes.
Glossary
●
93
stripe size
The amount of data in each section of a striped array.
striped array
T
task
An operation that occurs only on the RAID controller, asynchronous to all other operations; for example,
initializing a disk or verifying an array. Some tasks can take an extended period of time, particularly if the
RAID controller is also performing intensive data I/O while the task is running.
V
verify
Low-level check that a drive, logical device, or hot spare is good. In a RAID 1, verify is a low-level check that
contents of both members’ segments are consistent and, optionally, corrects errors while assuming that the
master drive is correct. In a simple volume, verify performs a low-level check that the whole drive can be
read.
