Chapter 1: Introduction to the Integrated RAID Solution
1.1
Overview
The LSI® Integrated RAID solution provides cost benefits for the server or workstation market that requires the extra
performance, storage capacity, and redundancy of a RAID configuration. The LSI Integrated RAID solution includes the
following RAID features:


The Integrated Mirroring solution, which provides features of RAID 1
The Integrated Striping solution, which provides features of RAID 0
By simplifying the configuration options and by providing firmware support in its SAS-3 host adapters, LSI can offer
the Integrated RAID solution at a lower cost than a hardware RAID implementation.
LSI Fusion-MPT™ firmware supports Integrated Mirroring volumes, Integrated Mirroring + Striping volumes,
Integrated Mirroring Enhanced volumes, and Integrated Striping volumes. You can create up to two Integrated RAID
volumes on each LSI SAS-3 controller.
The LSI Integrated RAID solution supports the following LSI SAS-3 controllers and the host bus adapters based on
these controllers:


LSISAS3008
LSISAS3004
LSI Integrated RAID firmware uses the same device drivers as the standard LSI Fusion-MPT-based controllers, thereby
eliminating the need for complex backup software or expensive RAID hardware. To conserve system resources, the
Integrated RAID firmware operates independently from the operating system. The BIOS-based configuration utility,
documented in Chapter 3, makes it easy to configure mirrored and striped volumes. The Integrated RAID solution is
currently available as an optional component of the Fusion-MPT architecture on LSI SAS-3 controllers.
NOTE In this document, the terms volume, RAID volume, array, and RAID array are used interchangeably.
Volume and array both appear on the screens of the BIOS-based configuration utility. The term disk means
both hard disk drive (HDD) and solid state drive (SSD), and the HDDs or SSDs can support either SAS or SATA
protocol.

Benefits and Features
Benefits and Features
The LSI Integrated RAID solution has the following benefits and features:



Support for up to 10 disks per Integrated RAID volume, with one or two volumes on each SAS-3 controller. Each
controller can support 14 volume drives, including one or two hot spare disks.
Support for two-disk Integrated Mirroring volumes (RAID 1).
Support for disk drives with 512-byte sectors and disk drives with 4-KB sectors.
NOTE An Integrated RAID volume must use all 512-byte-sector drives or all 4-KB-sector drives. You
cannot combine the two types of drives in a single volume. Also, some operating systems do not fully
support 4-KB-sector drives. Refer to the documentation for the operating system you are using.

1.2.1
Support for online capacity expansion (OCE) for RAID 1 volumes. OCE permits you to increase the size of a RAID 1
volume by replacing the disk drives with higher-capacity drives.
Support for RAID volumes, and physical disks within a RAID volume, where the volume or disk exceeds 241 bytes
(2.199 TB or 2 TiB).
Low-cost RAID volume creation, which meets the needs of most internal RAID installations.
Easy installation and configuration.
Support for booting from any kind of Integrated RAID volume.
Ability to operate without special operating system-specific software.
High reliability and data integrity.
— Nonvolatile write journaling.
— Physical disks in a volume are not visible to the operating system (OS) or to application software.
Low host CPU utilization and PCI® bus utilization.
Processing power provided by Fusion-MPT architecture. Shared-memory architecture minimizes external
memory requests.
Host Interface
The Integrated RAID host interface uses the message-passing interface. The Fusion-MPT interface gives the host OS
access to the RAID volumes as well as to additional non-RAID physical disks.
1.2.2
Metadata Support
The Integrated RAID firmware supports metadata, which describes the RAID volume configuration stored on each
member disk of a volume. After initialization, the firmware reads the metadata on each member disk and verifies the
configuration. The firmware reduces the usable disk space for each member disk when it creates the volume to make
room for the metadata.
1.2.3
SMART Support
The Self-Monitoring Analysis and Reporting Technology (SMART) monitors disk drives for signs of possible future disk
failure and generates an alert if it detects such signs. The Integrated RAID firmware polls each physical disk in the
volume at regular intervals. If the firmware detects a SMART ASC/ASCQ code on a physical disk in the volume, it stores
the SMART data in a log.

Fusion-MPT Support
The Integrated RAID BIOS uses the LSI Fusion-MPT interface to communicate to the SAS-3 controller and firmware.
This process includes reading the Fusion-MPT configuration to access the parameters that define behavior between
the SAS-3 controller and the devices that connect to it. The Fusion-MPT drivers for all supported operating systems
implement the Fusion-MPT interface to communicate with the controller and firmware.

Overview
Chapter 2: Overview of Integrated RAID Mirrored Volumes
This chapter provides an overview of the LSI Integrated RAID features that support the creation of mirrored volumes.
2.1
Overview
As a result of the shift towards network-attached storage (NAS), Internet service providers need a cost-effective,
fault-tolerant solution to protect the operating systems on small form-factor, high-density, rack-mountable servers.
The mirroring features of the LSI Integrated RAID solution provide such protection for the system boot volume, which
safeguards the operating system and other critical information on servers and high-performance workstations. The
Integrated RAID solution supports the following types of mirrored volumes:

The Integrated Mirroring solution, which provides features of RAID 1
These three mirroring solutions provide a robust, high-performance, fault-tolerant solution to data storage needs at a
lower cost than a dedicated RAID controller.
Mirrored volumes contain two disks to ten disks to provide fault-tolerant protection for critical data. Mirrored volumes
also support one or two global hot spare drives, with a maximum of 14 drives on each LSI SAS-3 controller.
NOTE Fourteen drives is the theoretical upper limit for a single LSI SAS-3 controller, although the controller
itself might support fewer than 14 drives. You can also configure one mirrored volume and one Integrated
Striping volume on the same LSI SAS controller.
Each SAS-3 controller can have two global hot spare disks available to automatically replace a failed disk in the one or
two mirrored volumes configured on the controller. The hot spares make the mirrored volumes even more fault
tolerant.
2.2
Integrated Mirroring Features
Integrated Mirroring support the following features:








Configurations of one or two mirrored volumes on each LSI SAS-3 controller. Each volume can consist of two
mirrored disks for an Integrated Mirroring volume; three to ten mirrored disks for an Integrated Mirroring
Enhanced volume; or four, six, eight, or ten mirrored disks for an Integrated Mirroring + Striping volume.
(Optional) Two global hot spare disks per LSI SAS-3 controller to automatically replace failed disks in mirrored
volumes.
Ability of mirrored volumes to run in optimal mode or in degraded mode if one mirrored disk in an Integrated
Mirroring volume fails or if one or more mirrored disks fail in an Integrated Mirroring + Striping volume or
Integrated Mirroring Enhanced volume.
Support for hot swapping.
Support for OCE for RAID 1 volumes. OCE permits you to increase the size of a RAID 1 volume by replacing the
existing disk drives with higher-capacity disk drives. Data is protected during the expansion process, and the
RAID 1 volume remains online.
Presentation of a single virtual drive to the operating system for each mirrored volume.
Support for both SAS disks and SATA disks, although you cannot combine the two types of disks in the same
volume. However, an LSI SAS-3 controller can support one volume with SATA disks and a second volume with
SAS disks.
Automatic background initialization after a volume is created.

Fusion-MPT architecture.
Menu-driven, BIOS-based configuration utility.
Error notification, in which the drivers update an OS-specific event log.
Support for SCSI Enclosure Services (SES) status LED.
Write journaling, which permits automatic synchronization of potentially inconsistent data after unexpected
powerdown situations.
Use of metadata to store volume configuration on disks in a mirrored volume.
Automatic background resynchronization while host I/O transactions continue.
Background media verification, which makes sure that data on mirrored volumes is always accessible.
Operation of Mirrored Volumes
The LSI Integrated RAID solution supports one or two mirrored volumes on each LSI SAS-3 controller (or one mirrored
volume and one Integrated Striping volume). Typically, one of these volumes is the boot volume. Boot support is
available through the firmware of the LSI SAS-3 controller that supports the standard Fusion-MPT interface. The
run-time mirroring of the boot disk is transparent to the BIOS, the drivers, and the operating system. Host-based
status software monitors the state of the mirrored disks and reports any error conditions. The following figure shows
an Integrated Mirroring volume in which the second disk is a mirrored copy of the data on the first (primary) disk.

You can configure an Integrated Mirroring Enhanced volume with up to 10 mirrored disks. The following figure shows
the logical view and physical view of an Integrated Mirroring Enhanced volume with three mirrored disks. The
firmware writes each mirrored stripe to a disk and mirrors it to an adjacent disk. RAID 1E is another term for this type of
mirrored configuration.
You can configure an Integrated Mirroring + Striping volume with an even number of disks, ranging from a minimum
of four disks to a maximum of ten disks. The following figure shows the logical view and physical view of an Integrated
Mirroring + Striping volume with four mirrored disks. The firmware writes each mirrored stripe to a disk and mirrors it
to an adjacent disk. RAID 10 is another term for this type of configuration.
The LSI SAS-3 BIOS configuration utility (SAS-3 BIOS CU) enables you to create mirrored volumes during initial setup
and to reconfigure them in response to hardware failures or changes in the environment.
CAUTION The SAS3 BIOS CU deletes all existing data from the disks drives when you select them to use for a
mirrored volume.
2.4
Mirrored Volume Features
This section describes features of Integrated Mirroring volumes, Integrated Mirroring + Striping volumes, and
Integrated Mirroring Enhanced volumes.
2.4.1
Resynchronization with Concurrent Host I/O Operation
The Integrated RAID firmware permits host I/O transactions to continue on a mirrored volume while it resynchronizes
the volume in the background. The firmware automatically starts resynchronizing data after a disk failure activates a
hot spare, or after a disk in a mirrored volume has been hot-swapped.
LSI Corporation

LSI Integrated RAID SAS 3.0 Solution User Guide

2.4.2
Chapter 2: Overview of Integrated RAID Mirrored Volumes
Mirrored Volume Features
Hot Swapping
The Integrated RAID firmware supports hot swapping, and it automatically resynchronizes the hot-swapped disk 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 verifies that the new physical disk has enough capacity for the mirrored
volume. The firmware resynchronizes all replaced hot-swapped disks, even if the same disk is removed and then
re-inserted. In a mirrored volume with an even number of disks, the firmware marks the hot-swapped disk as a
secondary disk and the other disk with data as the primary disk. The firmware resynchronizes all data from the primary
disk onto the new secondary disk. In a mirrored volume with an odd number of disks, primary and secondary sets
include three disks instead of two disks.
2.4.3
Hot Spare Disk
You can configure two disks as global hot spare disks to protect data on the mirrored volumes configured on the SAS-3
controller. If the Integrated RAID firmware fails one of the mirrored disks, it automatically replaces the failed disk with
a hot spare disk and then resynchronizes the mirrored data. The firmware automatically receives a notification when a
hot spare replaces the failed disk, and it then designates that disk as the new hot spare.
2.4.4
Online Capacity Expansion
The OCE feature enables you to expand the capacity of an existing two-disk Integrated Mirroring (RAID 1) volume by
replacing the original disk drives with higher-capacity drives that have the same protocol (SAS or SATA).
NOTE The replacement drives must have at least 50 GB more capacity than the original drives of the volume.
After you replace the disk drives and run the OCE command, you must use a commercial tool specific to the operating
system to move, or increase the size of, the partition on the volume.
2.4.5
Media Verification
The Integrated RAID firmware supports a background media verification feature that runs at regular intervals when the
mirrored volume is in the Optimal state. If the verification command fails for any reason, the firmware reads the other
disk’s data for this segment and writes it to the failing disk in an attempt to refresh the data. The firmware periodically
writes the current media verification logical block address to nonvolatile memory so the media verification can
continue from where it stopped prior to a power cycle.
2.4.6
Disk Write Caching
By default, the Integrated RAID firmware disables disk write caching for mirrored volumes to make sure that the write
journal entry stored in nonvolatile static RAM (NVSRAM) is always valid. If you enable disk write caching (not
recommended), you might cause the disk write log to be invalid.
2.4.7
NVSRAM Usage
The Integrated RAID firmware requires at least a 32-KB NVSRAM to perform write journaling for mirrored volumes on
LSI SAS-3 controllers. The NVSRAM also preserves configuration information across reboots. The firmware uses write
journaling to verify that the disks in the mirrored volume are synchronized with each other.

2.4.8
Chapter 2: Overview of Integrated RAID Mirrored Volumes
Creating Mirrored Volumes in BIOS
Background Initialization
Background initialization (BGI) is the process of copying data from primary to secondary disks in a mirrored volume.
The Integrated RAID firmware starts BGI automatically as a background task when it creates a volume. The volume
remains in the Optimal state while BGI is in progress.
2.4.9
Consistency Check
A consistency check is a background process that reads data from primary and secondary disks in a mirrored volume
and compares it to make sure the data is identical on both disks. Use the LSI SAS-3 BIOS Configuration Utility to run a
consistency check on a mirrored volume.
2.4.10
Make Data Consistent
If it is enabled in the Integrated RAID firmware, the make data consistent (MDC) process starts automatically and runs
in the background when you move a redundant volume from one LSI SAS-3 controller to another LSI SAS-3 controller.
MDC compares the data on the primary and secondary disks. If MDC finds inconsistencies, it copies data from the
primary disk to the secondary disk.
2.5
Creating Mirrored Volumes in BIOS
This chapter explains how to create Integrated Mirroring volumes with the LSI SAS-3 BIOS Configuration Utility (SAS3
BIOS CU).
2.5.1
Mirrored Volume Configuration Overview
The LSI SAS3 BIOS CU is a menu-driven utility program that enables you to easily configure and manage Integrated
RAID volumes. You can use the SAS3 BIOS CU to create one or two mirrored volumes on each LSI SAS-3 controller, with
up to two optional global hot spare disks. You must connect all disks in a mirrored volume to the same LSI SAS-3
controller.
Although you can use disks of different sizes in mirrored volumes, the smallest disk in the volume determines the
logical size of all disks in the volume. In other words, the volume does not use the excess space of the higher-capacity
member disks. For example, if you create an Integrated Mirroring Enhanced volume with two 100-GB disks and two
120-GB disks, the volume uses only 100 GB on each of the 120-GB disks.
See Chapter 2 for more information about the features of Integrated Mirroring, Integrated Mirroring + Striping, and
Integrated Mirroring Enhanced volumes.
2.5.2
Creating Mirrored Volumes
The SAS3 BIOS CU is part of the Fusion-MPT BIOS. When the BIOS loads during the startup sequence and you see the
message about the LSI Configuration Utility, press Ctrl-C to start the SAS3 BIOS CU. When you start the SAS3 BIOS CU,
the message changes to the following:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu (Adapter List window) of the SAS3 BIOS CU appears. On some systems, however,
the following message appears next:
LSI Corp Configuration Utility will load following initialization!

Chapter 2: Overview of Integrated RAID Mirrored Volumes
Creating Mirrored Volumes in BIOS
In this case, the SAS3 BIOS CU loads after the system completes its power-on self-test.
You can configure one or two Integrated Mirroring, Integrated Mirroring + Striping, and Integrated Mirroring
Enhanced volumes on each LSI SAS-3 controller. Alternatively, you can configure one mirrored volume and one
Integrated Striping volume on the same controller, up to a maximum of 14 disk drives for the two volumes. (The
maximum number includes one or two optional hot spare disks for the mirrored volume or volumes.) Additional
information about configuring a RAID volume follows:



All physical disks in a volume must be either SATA (with extended command set support) or SAS (with SMART
support). You cannot combine SAS and SATA disks in the same volume. However, you can create one volume with
SAS disks and a second volume with SATA disks on the same controller.
Disks in the volume must have 512-byte blocks and must not have removable media.
Integrated Mirroring volumes must have two disks, Integrated Mirroring Enhanced volumes contain three disks to
ten disks, and Integrated Mirroring + Striping volumes can have four, six, eight, or ten disks.
NOTE LSI strongly recommends that you create global hot spare disks for all mirrored volumes to increase the
level of data protection. If a disk in a mirrored volume fails, the Integrated RAID firmware rebuilds it using one
of the global hot spares, and the data is safe. If you create two mirrored volumes on an LSI SAS-3 controller,
either of the volumes can use the global hot spares if a disk fails.
2.5.2.1

Select Manage Volume.
The Manage Volume window appears.
Select Delete Array.
A menu window appears.
Either press Y to delete the array, or press N to cancel the deletion process.
After a pause, the utility deletes the array. If there is another remaining array and one or two hot spare disks, the
BIOS checks the hot spare disks to determine if they are compatible with the remaining array. If they are not
compatible (too small or wrong disk type), the BIOS deletes them also.
Locating Disk Drives in a Volume
You can use the SAS3 BIOS CU to locate and identify a specific physical disk drive in a disk enclosure by flashing the
drive’s LED. You can also flash the LEDs of all the disk drives in a RAID volume, if they are in a disk enclosure.
When you add a disk drive to a new mirrored volume, the LED on the disk drive starts flashing. The LED stops flashing
when you finish creating the volume.
To locate disk drives by flashing their LEDs, follow these steps.

NOTE The LEDs on the disk drives flash as previously described if the firmware configuration is correct
and the drives are in a disk enclosure.
2.5.4.6
Selecting a Boot Disk
You can select a boot disk in the SAS Topology window. The next time you boot the computer, the firmware moves
this disk to scan ID 0, making it the new boot disk. This feature makes it easier to set BIOS boot device options and to
keep the boot device constant during device additions and removals. You can also select an alternative boot device. If
the BIOS cannot find the preferred boot device when it loads, it attempts to boot from the alternative device.
Follow these steps to select a boot disk.

3.1
Overview of Integrated Striping
This chapter provides an overview of the LSI Integrated RAID features that support the creation of striped volumes.
3.1.1
Overview
The LSI Integrated RAID solution enables you to create Integrated Striping volumes for applications that require the
faster performance and increased storage capacity of striping. The low-cost Integrated Striping feature has many of
the advantages of more expensive RAID striping solutions. An Integrated Striping volume can be the boot disk or a
data disk.
The Integrated Striping solution provides better performance and more capacity than individual disks, without
burdening the host CPU. The firmware distributes host I/O transactions over multiple disks and presents the disks to
the OS as a single volume. In general, striping is transparent to the BIOS, the drivers, and the operating system.
Use the LSI SAS3 BIOS CU to configure Integrated Striping volumes.
3.1.2

Integrated Striping Description
On Integrated Striping volumes, the firmware writes data across multiple disks instead of onto one disk by
partitioning each disk’s storage space into 64-KB stripes. The firmware interleaves the stripes in such a way that the
combined storage space consists alternately of stripes from each disk.
The following figure shows an example of Integrated Striping. In this example, the firmware writes segment 1 to disk 1,
segment 2 to disk 2, segment 3 to disk 3, and so on. When the firmware reaches the end of the disk list, it continues
writing data at the next available segment of disk 1.

Speed is the primary advantage of the Integrated Striping solution because it transfers data to or from multiple disks
simultaneously. However, Integrated Striping volumes have no data redundancy. Back up the data on other media to
avoid losing unsaved data if one disk fails.

Chapter 3: Integrated Striping
Creating Integrated Striping Volumes in BIOS
Creating Integrated Striping Volumes in BIOS
This chapter explains how to create Integrated Striping volumes using the LSI SAS-3 BIOS Configuration Utility (SAS3
BIOS CU).
3.2.1
Integrated Striping Configuration Overview
The LSI SAS3 BIOS CU is a menu-driven utility program that enables you to easily configure and manage Integrated
RAID volumes. Use the SAS3 BIOS CU to create one or two Integrated Striping volumes on each LSI SAS-3 controller.
Each volume contains two drives to ten drives. All disks in an Integrated Striping volume must be connected to the
same LSI SAS-3 controller.
Although you can use disks of different sizes in Integrated Striping volumes, the smallest disk in the volume
determines the logical size of all disks in the volume. In other words, the firmware does not use the excess space of the
higher-capacity member disks. For example, if you create an Integrated Striping volume with two 100-GB disks and
two 120-GB disks, the firmware uses only 100 GB on each of the 120-GB disks for the volume. The supported stripe size
is 64 KB.
See Chapter 2 for more information about Integrated Striping volumes.
3.2.2
Creating Integrated Striping Volumes
The SAS3 BIOS CU is part of the Fusion-MPT BIOS. When the BIOS loads during boot and you see the message about
the LSI Configuration Utility, press Ctrl-C to start the SAS3 BIOS CU. After you start the SAS3 BIOS CU, the message
changes to the following:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu of the SAS3 BIOS CU appears. On some systems, however, the following message
appears next:
LSI Corp Configuration Utility will load following initialization!
In this case, the SAS3 BIOS CU loads after the system completes its power-on self-test.
Each LSI controller can support one or two Integrated RAID volumes. The volumes can include two Integrated Striping
(RAID 0) volumes, two mirrored volumes, or one volume of each type. The two volumes can have a maximum of
14 disk drives. (This configuration includes one or two hot spare disks for mirrored volumes.)
The following guidelines apply when creating an Integrated Striping volume:



All physical disks in the volume must be either SATA (with extended command set support) or SAS (with SMART
support). You cannot combine SAS and SATA disks in the same volume. However, it is possible to configure one
volume with SAS disks and one volume with SATA disks on the same controller.
Disks in the volume must have 512-byte blocks and must not have removable media.
Integrated Striping volumes must have at least 2 disks and no more than 10 disks. Integrated Striping volumes do
not support hot spare disks.

Introduction
4.1.1
Overview
The Human Interface Infrastructure (HII) Configuration Application is a tool used to configure controllers, physical
disks, and virtual disks, and to perform other configuration tasks in a pre-boot, Unified Extensible Firmware Interface
(UEFI) environment. This document explains how to use the HII interface to perform these tasks.
NOTE Different versions of the HII Configuration Application firmware exist for integrated RAID (IR) systems
and initiator-target (IT) systems. The Firmware Type property on the View Controller Properties window
indicates which version is running.
The IR version of the HII Configuration Application is documented in Section 4.3, Using the Integrated RAID
Version. This version lets you view system information, create virtual disks (RAID volumes), and perform other
management tasks on controllers, physical disks, and virtual disks.
NOTE The HII Configuration Application displays only the logical unit number (LUN) zero devices. It does not
display the LUN nonzero devices discovered by the boot services driver (BSD). This behavior is consistent with
the Configuration Utility (CU) provided by the LSI® Legacy (Int13) basic input/output system (BIOS).
4.1.2
Controller Support
The HII Configuration Application supports the following Avago SAS-2 and SAS-3 controllers, running IT or IR
firmware, and the host bus adapters based on the following controllers.

from another system. You might be unable to import a foreign configuration. The following conditions prevent an
import operation from succeeding:





The volume state is not INACTIVE.
The volume state is either FAILED or MISSING.
The volume uses incompatible Gen1 metadata.
The maximum number of two RAID volumes already exist on this controller.
The maximum number of supported physical drives are already in use in active volumes on this controller.
Global hot spares also count because they must be activated along with other drives in the foreign volume.

Appendix A: Using the SAS-3 Integrated RAID Configuration Utility
This appendix explains how to use the command-line-driven SAS-3 Integrated RAID configuration utility (SAS3IRCU)
to create and manage Integrated RAID volumes on LSI SAS-3 controllers.
You run SAS3IRCU commands from a command-line prompt or a shell script. When you use a SAS3IRCU command,
the program returns a status value to the operating system when it exits.
You can use SAS3IRCU to quickly and efficiently configure Integrated RAID devices on LSI SAS-3 controllers.
NOTE In this appendix, the term disk means HDD and solid state drive SSD, and the HDDs or SSDs can support
either SAS or SATA protocol.

Interface Description
Interface Description
Use this syntax for SAS3IRCU commands:
sas3ircu <controller_#> <command> <parameters>
Use a space to separate the program name, the controller number, the command, and the parameters fields. The
format of <parameters> is command specific.
Information passes between the user environment and SAS3IRCU through the command line, the standard output
and standard error interfaces, and the program return value. It is possible to redirect the output streams as permitted
by the operating system. When the program exits, it returns a value of 0 if the command is successful. Otherwise, it
returns a value of 1.
If a command fails, SAS3IRCU prints the IOCStatus and IOCLogInfo on the console. This information is useful in
determining the cause of the failure.

Appendix A: Using the SAS-3 Integrated RAID Configuration Utility
Commands
Common Command-Line Parameters
This section describes command-line parameters that are common to more than one command.


A.3.2
<controller_#>
The unique controller number that the program assigns to each PCI function found on supported controller chips
in the system, starting with controller # 0. For example, in a system containing two LSISAS3008 controllers,
controller # 0 references the first controller and controller # 1 references the other controller. Use the LIST
command to view a list of controllers connected to the system and the controller number for each controller.
Valid controller number values are 0 to 255 (decimal).
<Enclosure:Bay>
The enclosure and bay (or 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. Enclosure is a 16-bit EnclosureHandle value set by the I/O
controller (IOC). A value of 0 is invalid. Bay/Slot is a 16-bit slot value set by the IOC. Use the DISPLAY command to
determine the enclosure number and slot number of a drive.
CREATE
The CREATE command creates Integrated RAID volumes on LSI SAS-3 controllers.
When you add a disk to an Integrated RAID volume, the volume might not use all of the disk’s storage capacity. For
example, if you add a 300-GB disk drive to a volume that only uses 200 GB of capacity on each disk drive, the volume
does not use the remaining 100 GB of capacity on the disk drive.
The disk identified by the first Enclosure:Bay on the command line becomes the primary disk drive when you create an
Integrated Mirroring (RAID 1) volume. If the controller resynchronizes the disk drives, the data on the primary disk
drive becomes available when you access the newly created volume.
When the IR firmware creates a RAID 1 volume, it starts a background initialization of the volume. Use the STATUS
command to monitor the status of the initialization.
The following restrictions and defaults apply when you create Integrated RAID volumes and hot spare disks:







All disks that are part of a volume, including hot spares for that volume, must be connected to the same LSI SAS-3
controller.
The supported RAID levels are RAID 0, RAID 1, RAID 1E, and RAID 10.
You can create a maximum of two Integrated RAID volumes per LSI SAS-3 controller.
The maximum and minimum disk drives per RAID level are as follows:
— RAID 0: Max = 10; Min = 2.
— RAID 1: Max = 2; Min = 2.
— RAID 1E: Max = 10; Min = 3.
— RAID 10: Max = 10; Min = 3.
SAS3IRCU does not permit you to create an Integrated RAID volume that combines SAS and SATA hard disk drives.
SAS3IRCU does not permit you to create an Integrated RAID volume that combines solid-state drives (SSDs) and
hard disk drives.
SAS3IRCU supports disk drives with 512-byte sectors and disk drives with 4-KB sectors. However, an Integrated
RAID volume must use all 512-byte-sector drives or all 4-KB-sector drives. You cannot combine the two types of
drives in a single Integrated RAID volume.
NOTE Some operating systems do not fully support 4-KB-sector drives. Refer to the documentation for
the operating system you are using.
