1.1 Introduction
The LSI Logic Integrated RAID solution provides cost benefits for the
server or workstation market where the extra performance, storage
capacity, and/or redundancy of a RAID configuration are required. The
two components of Integrated RAID are:
•
Integrated Mirroring (IM), which provides features of RAID 1 and
RAID 1E (RAID 1 Enhanced). RAID 1E is also called Integrated
Mirroring Enhanced (IME)
•
Integrated Striping (IS), which provides features of RAID 0
By simplifying the IM and IS configuration options and by providing
firmware support in its host adapters, LSI Logic can offer the Integrated
RAID solution at a lower cost than a hardware RAID implementation.

2.1 Introduction
As a result of the shift towards Network Attached Storage (NAS), ISPs
need a cost effective, fault-tolerant solution to protect the operating
systems on small form factor, high-density, rack-mountable servers. The
LSI Logic Integrated Mirroring (IM) feature—which includes Integrated
Mirroring Enhanced (IME)—provide data protection for the system boot
volume to safeguard critical information such as the operating system on
servers and high performance workstations. The Integrated Mirroring
feature gives customers a robust, high-performance, fault-tolerant
solution to their storage needs, at a lower cost than a dedicated RAID
controller.
The Integrated Mirroring feature supports simultaneous mirrored volumes
with two disks (IM) or three to eight disks (IME), to provide fault-tolerant
protection for critical data. (If a hot spare disk is used, the maximum
volume size is seven mirrored disks, plus the hot spare disk.) Up to two
IM volumes are supported per SAS controller, with up to ten drives total
per controller.

Version 1.0

2-1
Note:
Ten disk drives is the theoretical upper limit, although the
SAS controller itself may support fewer drives.
If a disk in an Integrated Mirroring volume fails, the hot swap capability
allows the volume to be easily restored by simply swapping disks. The
firmware then automatically re-mirrors the swapped disk. Additionally,
each SAS controller can have one global hot spare disk available to
automatically replace a failed disk in the one or two IM or IME volumes
configured on the controller. The hot spare makes the Integrated
Mirroring volume even more fault-tolerant.
Note:
You can configure an Integrated Mirroring volume and an
Integrated Striping volume on the same LSI Logic SAS controller.
The IM feature uses the same device drivers as the standard LSI Logic
Fusion-MPT based controllers, providing seamless and transparent fault
tolerance. This eliminates the need for complex backup software or
expensive RAID hardware. The IM feature operates independently from
the operating system, in order to conserve system resources. The BIOSbased configuration utility makes it easy to configure IM and IME
volumes.
The Integrated Mirroring feature is currently available as an optional
component of the Fusion-MPT architecture on LSI Logic controller
products.
2.2 IM Features
LSI Logic Integrated Mirroring and Integrated Mirroring Enhanced
support the following features:
2-2
•
Configurations of one or two IM or IME volumes on the same LSI
Logic SAS controller. Each volume can consist of two mirrored disks
(IM) or three to eight mirrored disks (IME).
•
(Optional) One global hot spare disk per controller. If a global hot
spare disk is defined, the upper limit for an IME volume is seven
mirrored disks.
•
Mirrored volumes run in optimal mode or in degraded mode (if one
mirrored disk fails)

2.3 IM/IME Description
The LSI Logic Integrated Mirroring (IM) feature supports one or two
mirrored volumes on each LSI Logic SAS controller (or one mirrored
volume and one Integrated Striping volume). Typically, one of these
volumes is the boot volume, as shown in Figure 2.1. This is
accomplished through the firmware of the LSI Logic SAS controller that
supports the standard Fusion-MPT interface. The runtime mirroring of
the boot disk is transparent to the BIOS, drivers, and operating system.
Host-based status software monitors the state of the mirrored disks and
reports any error conditions. In Figure 2.1 the system is configured with
a second disk as a mirror of the first (primary) disk.

The advantage of Integrated Mirroring (RAID 1), is that there is always a
mirrored copy of the data. The disadvantage is that writes take longer
because data must be written twice. On the other hand, performance is
actually improved during reads.

Mirroring configuration with two disks in the mirrored volume.

LSI Logic provides the BIOS-based configuration utility to enable the user
to create IM and IME volumes during initial setup and to reconfigure
them in response to hardware failures or changes in the environment.
2.4 Integrated Mirroring Firmware
This section describes features of the LSI Logic Integrated Mirroring (IM)
firmware, which supports up to two IM volumes per LSI Logic SAS
controller.
2.4.1 Host Interface
The IM host interface uses the Message Passing Interface, as described
in the Fusion-MPT Message Passing Interface Specification. Through the
Fusion-MPT interface, the host OS has access to the IM volume as well
as the physical disks.
Integrated Mirroring Firmware
Version 1.0
Copyright © 2006 by LSI Logic Corporation. All rights reserved.
2-5
2.4.2 Resynchronization with Concurrent Host I/O Operation
The IM firmware allows Host I/Os to continue on the IM/IME volume
while the volume is being re-synchronized in the background.
Resynchronization is attempted after a hot spare is activated due to a
physical device failure, or after a hot swap has occurred to a physical disk
in the IM or IME volume.
2.4.3 Metadata Support
The firmware supports metadata, which describes the IM/IME logical
drive configuration stored on each member disk. When the firmware is
initialized, each member disk is queried to read the stored metadata in
order to verify the configuration. The usable disk space for each member
disk is adjusted down to leave room for this data.
2.4.4 Hot Swapping
The IM firmware supports hot swapping. The hot-swapped disk is
automatically resynchronized in the background, without any host or user
intervention. The firmware detects hot swap removal and disk insertion.
Following a hot swap event, the firmware readies the new physical disk
by spinning it up and verifying that it has enough capacity for the mirrored
volume. The IM firmware resynchronizes all hot-swapped disks that have
been removed, even if the same disk is re-inserted. In a two-disk
mirrored volume, the IM firmware marks the hot-swapped disk as the
secondary disk and marks the other mirrored disk as the primary disk.
The firmware resynchronizes all data from the primary disk onto the new
secondary disk.
2.4.5 SMART Support
The IM firmware enables Mode 6 SMART on the member disks in the
mirrored volume. Mode 6 SMART requires each physical disk to be
polled at regular intervals. If a SMART ASC/ASCQ code is detected on
a physical disk in the volume, the firmware processes the SMART data,
and the last received SMART ASC/ASCQ is stored in non-volatile
memory. The IM/IME volume does not support SMART directly, since it
is just a logical representation of the physical disks in the volume.
2-6
Integrated Mirroring Overview
Version 1.0
Copyright © 2006 by LSI Logic Corporation. All rights reserved.
2.4.6 Hot Spare Disk
One disk can be configured as a global hot spare disk, which protects
data on the one or two volumes configured on the controller. If the IM
firmware fails one of the mirrored disks, the firmware automatically
replaces it with the hot spare disk. The IM firmware then resynchronizes
the mirrored data. The IM firmware is automatically notified when the
failed disk has been replaced, and the firmware then designates that disk
as the new hot spare.
2.4.7 Media Verification
The IM firmware supports a background media verification feature that
runs at regular intervals when the IM/IME volume is in optimal mode. If
the verification command fails for any reason, the other disk’s data for
this segment is read and written to the failing disk in an attempt to refresh
the data. The current Media Verification Logical Block Address is written
to non-volatile memory occasionally to allow Media Verification to
continue approximately where it left off prior to a power-cycle.
2.4.8 Disk Write Caching
The IM firmware disables disk write caching by default. This is done to
increase data integrity, so that the disk write log stored in NVSRAM is
always valid. If disk write caching were enabled (not recommended), the
disk write log could be invalid.
2.4.9 NVSRAM Usage
For the LSISAS1064/1064E and LSISAS1068/1068E controllers, the IM
firmware requires at least a 32K NVSRAM in order to perform write
journaling. Write journaling is used to verify that the mirrored disks in the
IM/IME volume are synchronized with each other.

2-7
2.5 Fusion-MPT Support
The BIOS uses the LSI Logic Fusion-MPT interface to communicate to
the SAS controller and firmware to enable Integrated Mirroring. This
includes reading the Fusion-MPT configuration to gain access to the
parameters that are used to define behavior between the SAS controller
and the devices connected to it. The Fusion-MPT drivers for all
supported operating systems implement the Fusion-MPT interface to
communicate with the controller and firmware.

Chapter 3
Creating Integrated
Mirroring Volumes
This chapter describes how to create Integrated Mirroring (IM) and
Integrated Mirroring Enhanced (IME) volumes using the LSI Logic SAS
BIOS Configuration Utility (SAS BIOS CU). The chapter includes these
topics:
•
Section 3.1, “IM Configuration Overview,” page 3-1
•
Section 3.2, “Creating IM and IME Volumes,” page 3-2
•
Section 3.3, “Creating a Second IM or IME Volume,” page 3-6
•
Section 3.4, “Managing Hot Spares,” page 3-6
•
Section 3.5, “Other Configuration Tasks,” page 3-8
3.1 IM Configuration Overview
You can use the SAS BIOS CU to create one or two IM or IME volumes
on each LSI Logic SAS controller, with an optional global hot spare disk.
All disks in an IM or IME volume must be connected to the same LSI
Logic SAS controller.
Although you can use disks of different size in IM and IME volumes, the
smallest disk determines the “logical” size of each disk in the volume. In
other words, the excess space of the larger member disk is not used.
Refer to Section 2.2, “IM Features,” for more information about Integrated
Mirroring volumes.

3.2 Creating IM and IME Volumes
The SAS BIOS CU is part of the Fusion-MPT BIOS. When the BIOS
loads during boot and you see the message about the LSI Logic
Configuration Utility, press Ctrl-C to start the CU. After you do this, the
message changes to:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu of the SAS BIOS CU appears. On
some systems, however, the following message appears next:
LSI Logic Configuration Utility will load following
initialization!
In this case, the SAS BIOS CU will load after the system has completed
its power-on self test.
You can configure one or two IM or IME volumes per Fusion-MPT
controller. You can also combine IM, IME, and Integrated Striping
volumes on the same controller, up to a maximum of 10 physical disk
drives.
The following guidelines also apply when creating an IM or IME volume:
•
All physical disks in the volumes must be either SATA (with extended
command set support) or SAS (with SMART support). SAS and
SATA disks cannot be combined in the same volume.
•
Disks must have 512-byte blocks and must not have removable
media.
•
An IM volume must have two drives, plus an optional global hot
spare. An IME volume. An IME volume can have three to eight
drives, or three to seven drives if you also create a global hot spare.
Note:
3-2
If a disk in an IM or IME volume fails, it is rebuilt on the
global hot spare if one is available. So adding a global hot
spare greatly increases the level of data protection. (One
global hot spare is allowed for the one or two volumes
configured on a controller.)

The Create New Array screen shows a list of disks that can be added
to a volume.
5. Move the cursor to the “RAID Disk” column and select a disk. To add
the disk to the volume, change the “No” to “Yes” by pressing the +
key, − key, or space bar.
When the first disk is added, the SAS BIOS CU prompts you to either
keep existing data or overwrite existing data.

6. Press M to keep the existing data on the first disk or press D to
overwrite it.
If you keep the existing data, this is called a migration. The first disk
will be mirrored onto the second disk, so the data you want to keep
must be on the first disk added to the volume. Any data on the
second disk is overwritten.
As disks are added the Array Size field changes to reflect the size of
the new volume.
7. (optional) Add a global hot spare by moving the cursor to the hot
spare column and pressing the + key, − key, or space bar.
Figure 3.2 shows an IM volume configured with a global hot spare
disk.

3.5 Other Configuration Tasks
This section explains how to do other tasks related to configuring and
maintaining IM and IME volumes.
3.5.1 Viewing Volume Properties
Follow these steps to view the properties of volumes:
1. In the SAS BIOS CU, select an adapter from the Adapter List. Select
the RAID Properties option.
The properties of the current volume are displayed. If a global hot
spare is defined, it is also listed.
Note:
If you create one volume using SAS disks, another volume
using SATA disks, and a global hot spare disk, the hot
spare disk will only appear when you view the volume that
has the same type of disks as the hot spare disk.
2. If two volumes are configured, press Alt+N to view the other array.
3. To manage the current array, select the Manage Array item and
press Enter.
3.5.2 Synchronizing an Array
The Synchronize Array command forces the firmware to resynchronize
the data on the mirrored disks is the array. It is seldom necessary to use
this command, because the firmware automatically keeps the mirrored
data synchronized during normal system operation. When you use this
command, one disk of the array is placed in the Degraded state until the
data on the mirrored disks has been resynchronized.
Follow these steps to force the synchronization of a selected array:
1. Select Synchronize Array on the Manage Array screen.
2. Press Y to start the synchronization, or N to cancel it.

3.5.3 Activating an Array
An array can become inactive if, for example, it is removed from one
controller or computer and moved to another one. The “Activate Array”
option allows you to reactivate an inactive array that has been added to
a system. This option is only available when the selected array is
currently inactive.
Follow these steps to activate a selected array
1. Select Activate Array on the Manage Array screen.
2. Press Y to proceed with the activation, or press N to abandon it.
After a pause, the array will become active.
Note:
If there is a global hot spare disk on the controller to which
you have moved the array, the firmware checks when you
activate the array to determine if the hot spare is
compatible with the new array. An error message appears
if the disks in the activated array are larger than the hot
spare disk or if the disks in the activated array are not the
same type as the hot spare disk (SATA versus SAS).
3.5.4 Deleting an Array
CAUTION:
Before deleting an array, be sure to back up all data on the
array that you want to keep.
Follow these steps to delete a selected array:
1. Select Delete Array on the Manage Array screen.
2. Press Y to delete the array.
After a pause, the firmware deletes the array. If there is another
remaining array and a global hot spare disk, the firmware checks the
hot spare disk to determine if it is compatible with the remaining
array. If the hot spare disk is not compatible (too small or wrong disk
type) the firmware deletes it also.
Note:
After a volume has been deleted, it cannot be recovered.
When a RAID 1 volume is deleted, the data is preserved
on the primary disk. The master boot records (MBR) of
Other Configuration Tasks

3-9
other disks in the array are deleted. For other RAID types,
the master boot records of all disks are deleted.
3.5.5 Locating a Disk Drive, or Multiple Disk Drives in a Volume
You can use the SAS BIOS CU to locate and identify a specific physical
disk drive by flashing the drive’s LED. You can also use the SAS BIOS
CU to flash the LEDs of all the disk drives in a RAID volume. There are
several ways to do this:
•
When you are creating an IM or IME volume, and a disk drive is set
to Yes as part of the volume, the LED on the disk drive is flashing.
The LED is turned off when you have finished creating the volume.
•
You can locate individual disk drives from the SAS Topology screen.
To do this, move the cursor to the name of the disk in the Device
Identifier column and press Enter. The LED on the disk flashes until
the next key is pressed.
•
You can locate all the disk drives in a volume by selecting the volume
on the RAID Properties screen. The LEDs flash on all disk drives in
the volume.
Note:
The LEDs on the disk drives will flash as described above
if the firmware is correctly configured and the drives or the
disk enclosure supports disk location.
3.5.6 Selecting a Boot Disk
You can select a boot disk in the SAS Topology screen. This disk is then
moved to scan ID 0 on the next boot, and remains at this position. This
makes it easier to set BIOS boot device options and to keep the boot
device constant during device additions and removals. There can be only
one boot disk.
Follow these steps to select a boot disk:
1. In the SAS BIOS CU, select an adapter from the Adapter List.
2. Select the SAS Topology option.
The current topology is displayed. If the selection of a boot device is
supported, the bottom of the screen lists the Alt+B option. This is the
key for toggling the boot device. If a device is currently configured as
3-10

the boot device, the Device Info column on the SAS Topology screen
will show the word “Boot.”
3. To select a boot disk, move the cursor to the disk and press Alt+B.
4. To remove the boot designator, move the cursor down to the current
boot disk and press Alt+B. This controller will no longer have a disk
designated as boot.
5. To change the boot disk, move the cursor to the new boot disk and
press Alt+B. The boot designator will move to this disk.
Note:
The firmware must be configured correctly in order for the
Alt+B feature to work.

Integrated Striping (IS)
Overview
This chapter provides an overview of the LSI Logic Integrated Striping
(IS) feature. It includes these sections:
•
Section 4.1, “Introduction,” page 4-1
•
Section 4.2, “IS Features,” page 4-2
•
Section 4.3, “IS Description,” page 4-2
•
Section 4.4, “Integrated Striping Firmware,” page 4-4
•
Section 4.5, “Fusion-MPT Support,” page 4-5
4.1 Introduction
The LSI Logic Integrated Striping (IS) feature is useful for applications
that require the faster performance and increased storage capacity of
striping. The low-cost IS feature has many of the advantages of a more
expensive RAID striping solution. A single IS logical drive may be
configured as the boot disk or as a data disk.
The IS feature is implemented with controller firmware that supports the
Fusion-MPT Interface. IS provides better performance and more capacity
than individual disks, without burdening the host CPU. The firmware
splits host I/Os over multiple disks and presents the disks as a single
logical drive. In general, striping is transparent to the BIOS, the drivers,
and the operating system.
The SAS BIOS CU is used to configure IS volumes, which can consist
of two to eight disks.
Note:
Integrated Mirroring and Integrated Striping volumes can be
configured on the same LSI logic SAS controller.

4.2 IS Features
Integrated Striping supports the following features:
•
Support for volumes with two to eight drives
•
Support for two IS volumes, with up to 10 drives total, on a controller.
An IS volume can also be combined with an IM or IME volume.
Note:
Currently available LSI Logic SAS controllers support a
maximum of eight drives. All drives in a volume must be
connected to the same SAS controller.
•
Presents a single virtual drive to the OS for each configured volume
•
Support for both SAS and SATA drives, although the two types of
drives cannot be combined in one volume
•
Fusion-MPT architecture
•
Easy-to-use SAS BIOS configuration utility
•
Error notification
•
Use of metadata to store volume configuration on disks
•
OS-specific event log
•
Error display inside the Fusion-MPT BIOS
•
SES status LED support for drives used in IS volumes
4.3 IS Description
The IS feature writes data across multiple disks instead of onto one disk.
This is accomplished by partitioning each disk’s storage space into
64 Kbyte stripes. These stripes are interleaved round-robin, so that the
combined storage space is composed alternately of stripes from each
disk.
For example, as shown in Figure 4.1, segment 1 is written to disk 1,
segment 2 is written to disk 2, segment 3 is written to disk 3, and so on.
When the system reaches the end of the disk list, it continues writing
data at the next available segment of disk 1.

The primary advantage of IS is speed, because it transfers data to or
from multiple disks at once. However, there is no data redundancy;
therefore, if one disk fails, that data is lost.

4.4 Integrated Striping Firmware
This section describes features of the LSI Logic Integrated Striping (IS)
firmware.
4.4.1 Host Interface
The IS host interface uses the Message Passing Interface, as described
in the Fusion-MPT Message Passing Interface Specification, including
Integrated Striping. Through the Fusion-MPT interface, the host
operating system has access to the logical IS drive as well as the
physical disks.
4.4.2 Metadata Support
The firmware supports metadata, which describes the IS logical drive
configuration stored on each member disk. When the firmware is
initialized, each member disk is queried to read the stored metadata to
verify the configuration. The usable disk space for each IS member disk
is adjusted down to leave room for this data.
4.4.3 SMART Support
The IS firmware enables Mode 6 SMART on the IS member disks.
Mode 6 SMART requires each physical disk to be polled at regular
intervals. If a SMART ASC/ASCQ code is detected on a physical IS disk,
the firmware processes the SMART data, and the last received SMART
ASC/ASCQ is stored in non-volatile memory. The IS volume does not
support SMART directly, since it is just a logical representation of the
physical disks in the volume.
4.4.4 Disk Write Caching
Disk write caching is disabled by default on all IS volumes.

Integrated Striping (IS) Overview

4.5 Fusion-MPT Support
The BIOS uses the LSI Logic Fusion-MPT interface to communicate to
the SAS controller and firmware to enable Integrated Striping. This
includes reading the Fusion-MPT configuration to gain access to the
parameters that are used to define behavior between the SAS controller
and the devices connected to it. The Fusion-MPT drivers for all
supported operating systems implement the Fusion-MPT interface to
communicate with the controller and firmware.

Chapter 5
Creating Integrated
Striping Volumes
This chapter describes how to create Integrated Striping (IS) volumes
using the LSI Logic SAS BIOS Configuration Utility (SAS BIOS CU). The
chapter includes these topics:
•
Section 5.1, “IS Configuration Overview,” page 5-1
•
Section 5.2, “Creating IS Volumes,” page 5-2
•
Section 5.3, “Creating a Second IS Volume,” page 5-4
•
Section 5.4, “Other Configuration Tasks,” page 5-5
5.1 IS Configuration Overview
You can use the SAS BIOS CU to create multiple IS volumes, with up to
10 drives total on an LSI Logic SAS controller. Each volume can have
from 2 to 8 drives. Disks in an IS volume must be connected to the same
LSI Logic SAS controller, and the controller must be in the BIOS boot
order.
Although you can use disks of different size in IS volumes, the smallest
disk determines the “logical” size of each disk in the volume. In other
words, the excess space of the larger member disk is not used. Usable
disk space for each disk in an IS volume is adjusted down to leave room
for metadata. Usable disk space may be further reduced to maximize the
ability to interchange disks in the same size classification. The supported
stripe size is 64 Kbytes.
Refer to Section 4.2, “IS Features,” for more information about Integrated
Striping volumes.

5.2 Creating IS Volumes
The SAS BIOS CU is part of the Fusion-MPT BIOS. When the BIOS
loads during boot and you see the message about the Setup Utility, press
Ctrl-C to start it. After you do this, the message changes to:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu of the SAS BIOS CU appears. On
some systems, however, the following message appears next:
LSI Logic Configuration Utility will load following
initialization!
In this case, the SAS BIOS CU will load after the system has completed
its power-on self test.
Follow the steps below to configure an Integrated Striping (IS) volume
with the SAS BIOS CU. The procedure assumes that the required
controller(s) and disks are already installed in the computer system. You
can configure both IM and IS volumes on the same SAS controller.
1. On the Adapter List screen of the SAS BIOS CU, use the arrow keys
to select a SAS adapter.
2. Press Enter to go to the Adapter Properties screen, shown in
Figure 5.1.

volume, change the “No” to “Yes” by pressing the + key, − key, or
space bar. As disks are added, the Array Size field changes to reflect
the size of the new volume.
There are several limitations when creating an IS (RAID 0) volume:
–
All disks must be either SATA (with extended command set
support) or SAS (with SMART support).
–
Disks must have 512-byte blocks and must not have removable
media.
–
There must be at least 2 and no more than 8 drives in a valid IS
volume. Hot spare drives are not allowed.

Note:
Integrated Striping does not provide any data protection in
the event of disk failure. It is primarily used to increase
speed.
5.3 Creating a Second IS Volume
The LSI Logic SAS controllers allow you to configure two IS volumes, or
an IS volume and an IM or IME volume. If one volume is already configured, and if there are available disk drives, there are two ways to add a
second volume. The first is as follows:
1. In the configuration utility, select an adapter from the Adapter List.
Select the RAID Properties option.
This will display the current volume.

2. Press C to create a new volume.
3. Continue with step 4 of Section 5.2, “Creating IS Volumes,” to create
a second IS volume.
The other way in which to add a second volume is as follows:
1. On the Adapter List screen, use the arrow keys to select an LSI
Logic SAS adapter.
2. Press Enter to go to the Adapter Properties screen, shown in
Figure 5.1.
3. On the Adapter Properties screen, use the arrow keys to select RAID
Properties and press Enter.
4. Continue with step 4 of the IS creation procedure in the previous
section to create a second volume.
5.4 Other Configuration Tasks
This section explains how to do other tasks related to configuring and
maintaining IS volumes.
5.4.1 Viewing IS Volume Properties
Follow these steps to view the properties of IS volumes:
1. In the configuration utility, select an adapter from the Adapter List.
Select the RAID Properties option.
The properties of the current volume are displayed.
2. If more than one volume is configured, press Alt+N to view the next
array.
3. To manage the current array, press Enter when the Manage Array
item is selected.
5.4.2 Activating an Array
An array can become inactive if, for example, it is removed from one
controller or computer and moved to another one. The “Activate Array”
option allows you to reactivate an inactive array that has been added to

a system. This option is only available when the selected array is
currently inactive.
Follow these steps to activate a selected array.
1. Select Activate Array on the Manage Array screen.
2. Press Y to proceed with the activation, or press N to abandon it.
After a pause, the array will become active.
5.4.3 Deleting an Array
CAUTION:
Before deleting an array, be sure to back up all data on the
array that you want to keep.
Follow these steps to delete a selected array:
1. Select Delete Array on the Manage Array screen.
2. Press Y to delete the array, or press N to abandon the deletion.
After a pause, the firmware deletes the array.
Note:
Once a volume has been deleted, it cannot be recovered.
The master boot records of all disks are deleted.
5.4.4 Locating a Disk Drive, or Multiple Disk Drives in a Volume
You can use the SAS BIOS CU to locate and identify a specific physical
disk drive by flashing the drive’s LED. You can also use the SAS BIOS
CU to flash the LEDs of all the disk drives in a RAID volume. There are
several ways to do this:
5-6
•
When you are creating an IS volume, and a disk drive is set to Yes
as part of the volume, the LED on the disk drive is flashing. The LED
is turned off when you have finished creating the volume.
•
You can locate individual disk drives from the SAS Topology screen.
To do this, move the cursor to the name of the disk in the Device
Identifier column and press Enter. The LED on the disk flashes until
the next key is pressed.
•
You can locate all the disk drives in a volume by selecting the volume
on the RAID Properties screen. The LEDs flash on all disk drives in
the volume.
Creating Integrated Striping Volumes
Version 1.0
Copyright © 2006 by LSI Logic Corporation. All rights reserved.
Note:
The LEDs on the disk drives will flash as described above
if the firmware is correctly configured and the drives or the
disk enclosure supports disk location.
5.4.5 Selecting a Boot Disk
You can select a boot disk in the SAS Topology screen. This disk is then
moved to scan ID 0 on the next boot, and remains at this position. This
makes it easier to set BIOS boot device options and to keep the boot
device constant during device additions and removals. There can be only
one boot disk.
Follow these steps to select a boot disk:
1. In the SAS BIOS CU, select an adapter from the Adapter List.
2. Select the SAS Topology option.
The current topology is displayed. If the selection of a boot device is
supported, the bottom of the screen lists the Alt+B option. This is the
key for toggling the boot device. If a device is currently configured as
the boot device, the Device Info column on the SAS Topology screen
will show the word “Boot.”
3. To select a boot disk, move the cursor to the disk and press Alt+B.
4. To remove the boot designator, move the cursor down to the current
boot disk and press Alt+B. This controller will no longer have a disk
designated as boot.
5. To change the boot disk, move the cursor to the new boot disk and
press Alt+B. The boot designator will move to this disk.
Note:
The firmware must be configured correctly in order for the
Alt+B feature to work.

to create Integrated Mirroring (IM), Integrated Mirroring Enhanced (IME)
and Integrated Striping (IS) volumes. CFGGEN is a command line utility
that runs in the DOS, Linux, EFI, and Windows Pre-Installation (WinPE)
environments. CFGGEN is a minimally interactive program that can be
executed from a command line prompt or a shell script. The result from
invoking this utility is communicated via the program status value that is
returned when the program exits.
CFGGEN can be used to create IM, IME, and IS storage configurations
on both SCSI controllers and SAS controllers. As noted in this Appendix,
some CFGGEN commands work only with SAS controllers, in the EFI
environment.
The appendix includes these topics:
•
Section A.1, “Hardware and Software Requirements”
•
Section A.2, “CFGGEN Interface Description”
•
Section A.3, “CFGGEN Commands”
Note:
CFGGEN is intended for use only in the manufacturing
environment. End users can use the BIOS-based configuration utility to create IM and IS volumes. (See Chapter 3,
“Creating Integrated Mirroring Volumes” and Chapter 5,
“Creating Integrated Striping Volumes”.)

A.1
Hardware and Software Requirements
The CFGGEN IR Configuration Utility runs on any Intel IA-32 or IA64
compatible platform. It will work with any SCSI, SATA, or SAS device that
is compliant with existing SCSI standards. CFGGEN supports the
following LSI Logic controllers:
•
LSI53C1020 and LSI53C1030 SCSI controllers (DOS, Linux, and
WinPE environments only)
•
SAS1064/1064E and SAS1068/1068E SAS controllers (DOS, Linux,
EFI, and WinPE environments)
The supported versions of CFGGEN are as follows:
DOS Version –
CFGGEN will run in any environment that is fully DOS compatible and
has at least 640 Kbytes of memory. The system BIOS must support
32-bit BIOS services, including the PCI BIOS services. CFGGEN uses
these services to locate the controller and its interface registers.
CFGGEN must be able to directly access the controller chip’s interface
registers.
Note:
You cannot run CFGGEN in a virtual DOS window from
within Windows.
EFI Version –
CFGGEN will run in any environment that is fully EFI compatible.
Currently, this includes only the SAS controllers listed above.
Linux Version –
CFGGEN is a statically linked Linux application. Static linking prevents
any library version compatibility problems that might stop CFGGEN from
working with a specific release or distribution of Linux. Version 3.02.04
or newer of the LSI mptlinux driver must be installed on the system. The
required modules include mptbase.o, mptscsih.o and mptctl.o.
Caution:
A-2
mptbase.o, mptscsih.o and mptctl.o must be loaded into
the Linux kernel before CFGGEN will function correctly.
They can be loaded using the Linux modprobe command.

WinPE Version –
CFGGEN will run on a Windows Pre-Installation Environment (WinPE)
and is statically compiled with the LSI MptLib Library (MptLib.lib). The
WinPE environment must have the appropriate LSI Logic MPT Windows
driver (Miniport or Storport) installed and loaded in order to recognize
and communicate with the I/O controller.
The WinPE utility does not recognize an LSI53C1030 or LSI53C1020
controller, unless there is at least one device attached to the controller.
A.2
CFGGEN Interface Description
CFGGEN uses a command line interface. Commands are formatted as
follows:
cfggen <controller #> <command> <parameters>
The program name, controller number, command, and parameters fields
must be separated by the ASCII space character. The format of the
parameters is command specific, as described in Section A.3, “CFGGEN
Commands.”
Information is passed between the user environment and CFGGEN via
the command line, the standard output and standard error interfaces, and
the program return value. The user can redirect the output streams as
permitted by the operating environment. The program return value is
returned to the user when the program exits. A value of 0 is returned if
the command is successful. Otherwise, a value of 1 is returned.
A.3
CFGGEN Commands
CFGGEN has the following commands:
•
CREATE
•
DEFAULTS (called DELETE in the EFI version)
•

Text in italics must be entered exactly as shown on the command line.
•
Text surrounded by <> must be replaced with a required parameter.
•
Text surrounded by [ ] may be replaced by an optional parameter.
•
Parameters surrounded by {} must be entered one or more times, as
is appropriate for the command being executed.
•
The command line definition characters <>, [ ], and {} must not be
entered on the command line.
Common Command Line Parameters
This section describes CFGGEN command line parameters that are
common to more than one command.
•
<controller #>
The unique controller number of a PCI function found in the system,
starting with controller # 0. For LSI Logic SCSI controllers, PCI
function means SCSI bus. Therefore, the controller # is used to
address a particular SCSI bus in the system. For example, CFGGEN
assigns two controller numbers to an LSI53C1030 dual SCSI bus
chip. It assigns one controller number to an LSI53C1020 single SCSI
bus chip.
For the LSI Logic SAS1064/1064E and SAS1068/1068E controllers
the controller # corresponds to a single SAS controller. For example,
A-4
Using the CFGGEN IR Configuration Utility
Version 1.0

in a system containing two SAS1068 controllers, controller # 0
references the first controller and controller # 1 references the other
controller.
Valid controller number values are 0–255 (decimal).
•
<SCSI ID>
The SCSI bus address of a peripheral device attached to an LSI
Logic controller. The maximum value of SCSI ID depends on the type
of I/O controller and the maximum number of devices supported by
the OS for this controller.
Valid SCSI ID values are:
0–15 (decimal) per SCSI bus for LSI53C1020/1030 controllers
0–127 (decimal) per controller for SAS1064/1064E and
SAS1068/1068E controllers
Note:
•
With PBSRAM, the SAS1068/1068E controllers can support more than 128 devices.
<Enclosure:Bay>
The Enclosure and bay/slot of a peripheral device attached to the
bus. The argument must use a colon (:) as a separator and must
follow the enclosure:bay format. This argument is only valid when
used with the bay argument on the command line.
Valid numbers are 0–127 (decimal) for SAS1064/1064E and
SAS1068/1068E controllers.
A.3.2
CREATE Command
The CREATE command creates IM, IME, and IS volumes on the
LSI53C1020/1030 and SAS1064/1064E and SAS1068/1068E
controllers. The firmware and hardware limitations for these controllers
determine the number of configurations that can be created.
When a disk drive is added to an IM, IME, or IS volume, its entire storage
capacity may or may not be used, depending on drive capacity and
volume capacity. For example, if you add a 36 Gbyte disk drive to a
volume that only uses 9 Gbytes of capacity on each disk drive, the
remaining 27 Gbytes of capacity on the disk drive is unusable.
The disk identified by the first SCSI ID on the command line is assigned
as the primary disk drive when an IM volume is created. If the controller
CFGGEN Commands

A-5
is allowed to resync the disk drives, the data on the primary disk drive
will be available when you access the newly created volume.
The following rules must be observed when creating IM, IME, and IS
volumes and hot spare disks:
1. All disks that are part of a volume, including hot spares for that
volume, must be on the same SAS controller or on the same SCSI
bus (for SCSI controllers).
2. IM, IME, and IS volumes are supported.
3. A maximum of two IM, IME, or IS volumes per controller can be
created.
4. The total number of disks in a volume, including hot spares disks,
cannot exceed six for LSI53C1020/1030 controllers.
5. The total number of disks in a volume, including hot spare disks,
cannot exceed eight for SAS1064/1064E and SAS1068/1068E
controllers, and the total number of disks combined for two volumes
cannot exceed ten. (Ten disks is a theoretical upper limit for the
firmware; the SAS controller may actually support a lesser number
of disks.)
6. An IM volume must have exactly two disks.
7. An IME volume can have a minimum of three disks and a maximum
of six disks (for LSI53C1020/1030 controllers) or eight disks (for SAS
controllers), as long as rules 4 and 5 are not violated.

available to be assigned to a disk array or hot spare pool.
•
Available (AVL) – Drive may or may not be ready, and it is not
suitable for inclusion in an array or hot spare pool (i.e., it is not spun
up, its block size is incorrect, or its media is removable).
•
Failed (FLD) – Drive was part of a logical drive or was a hot spare
drive, and it failed. It has been taken offline.
•
Standby (SBY) – This status is used to tag all non-hard disk drive
devices.
FORMAT Command
The FORMAT command is used to perform a low-level format of a disk
drive. The drive cannot be a hot spare drive or a member of an IM, IME,
or IS volume.
WARNING: A low-level format erases all data on the hard disk drive.
The FORMAT command cannot and should not be interrupted; doing so may result in irreparable damage to the
hard disk drive.
Warning messages are displayed during the formatting, unless the
noprompt option is included on the command line. If the user does not
quickly respond to a series of prompts, the command is aborted. The
answers are case sensitive and must be entered in upper case.

HOTSPARE Command
The HOTSPARE command creates a hot spare disk drive, which is
added to hot spare pool 0. The number of disk drives in an IM, IME, or
IS volume, including the hot spare disk cannot exceed six for
LSI53C1020/1030 controllers and eight for LSI1064/1064E and
LSI1068/1068E controllers. Only one hot spare disk can be created.
The capacity of the hot spare disk must be greater than or equal to the
capacity of the smallest disk in the logical drive. An easy way to verify
this is to use the DISPLAY command.
The following rules must be observed when creating hot spare disks:
A-12
Using the CFGGEN IR Configuration Utility
Version 1.0

SETOFFLINE Command
Note:
The SETOFFLINE command is supported by the DOS,
Linux, and WinPE versions of CFGGEN only.
The SETOFFLINE command makes a physical disk in a volume offline.
A physical disk that is taken offline changes its state to Failed (FLD), but
the disk is still associated with the volume and therefore cannot be
addressed by normal I/O requests. If a new disk replaces an offline disk,
the new disk is automatically brought online. Otherwise, the disk remains
offline until explicitly brought online by SETONLINE command.
Command Line –
cfggen
<controller #> setoffline <SCSI ID>
Parameters –
•
<controller #> – Number of the SCSI bus or SAS controller
targeted by this command.
•
<SCSI ID> – SCSI target ID of the drive targeted by this command.
Program Return Value –

The SETONLINE command brings a physical disk in a volume online,
which is required only after the physical disk has been taken offline by
the SETOFFLINE command. When a physical disk is brought online, the
IOC synchronizes the volume.

A.3.10 AUTO Command (EFI Version Only)
The AUTO command, which is currently supported only in the EFI
version of CFGGEN, automatically creates an IM, IME, or IS volume on
an LSI1064/1064E or LSI1068/1068E controller. The volume is created
with the maximum number of disks available for use in the specified
volume type. The main difference from the CREATE command is that
with the AUTO command you do not specify SCSI ID values for disks to
use in the volume. CFGGEN automatically creates the volume with the
first usable disks it finds. Firmware and hardware limitations for the family
of controllers limit the number of configurations that are possible.
When a disk drive is added to an IM, IME, or IS volume, its entire storage
capacity may or may not be used, depending on drive capacity and
volume capacity. For example, if you add a 36 Gbyte disk drive to a
volume that only uses 9 Gbytes of capacity on each disk drive, the
remaining 27 Gbytes of capacity on the disk drive are unusable.
When AUTO creates an IM volume, the first disk found is assigned as
the primary disk drive. If the controller is allowed to resync the disk
drives, the data on the primary disk drive will be available by accessing
the newly created volume.
CFGGEN follows these rules when creating IM, IME, and IS volumes and
hot spare disks with the AUTO command:
1. All disks that are part of a volume or a hot spares for a volume must
be connected to the same controller.
2. IM, IME, and IS volumes are supported.
3. Only two volumes per controller can be created.
A-16
Using the CFGGEN IR Configuration Utility
Version 1.0
Copyright © 2006 by LSI Logic Corporation. All rights reserved.
4. SAS and SATA drives cannot be mixed in a volume. With the AUTO
command, all drives used must be the same type as the first
available disk found.
5. The total number of disks in a volume, including hot spare disks,
cannot exceed eight for LSI1064/1064E and LSI1068/1068E
controllers, and the total number of disks combined for two volumes
cannot exceed ten.
6. An IM volume must have exactly two disks.
7. An IME volume can have three to six/eight disks as long as rules 4
and 5 are not violated.
Command Line –
cfggen <controller #> auto <volume type> <size>
[qsync] [noprompt]
Parameters –
•
<controller #> – Number of the SAS controller targeted by this
command.
•
<volume type> – Volume type for the volume to be created. Valid
values are IM, IME and IS.
•
<size> – Size of the RAID volume in Mbytes, or MAX for the
maximum size available.
•
[qsync] – If this optional parameter is specified, a quick
synchronization of new volume will be performed. If the volume type
is IME or IS, a quick synchronization is always performed even if this
option is not specified. A quick synchronization means that the first
32 Kbytes of the drives in the volume are cleared to 0.
•
noprompt – Suppresses display of warnings and prompts.
Program Return Value –

A.3.11 DISABLEIR Command (EFI Version Only)
The DISABLEIR command, which is currently supported only in the EFI
version of CFGGEN, disables Integrated RAID functionality on an
LSI1064/1064E or LSI1068/1068E controller. This is done by setting the
