Chapter 1 Introduction to Integrated RAID

This chapter provides an overview of Integrated RAID, its features, and its beneﬁts. The chapter includes these sections:

• Section 1.1, “Introduction,” page 1-1

• Section 1.2, “Integrated RAID Beneﬁts and Features,” page 1-2

• Section 1.3, “Using this Manual,” page 1-2

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

• 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 full-blown RAID implementation.

LSI Logic CIM interface software is used to continuously monitor IM volumes and IS volumes and to report status and error conditions as they arise.

IM and IS are supported by different versions of Fusion-MPT ﬁrmware. Therefore, either IM or IS can be implemented on a system with a Fusion-MPT based controller, but IM and IS cannot be used concurrently on the same system.

Integrated RAID User’s Guide 1-1

Chapter 2 Integrated Mirroring (IM) Overview

This chapter provides an overview of the LSI Logic Integrated Mirroring (IM) feature and includes these sections:

• Section 2.1, “Introduction,” page 2-1

• Section 2.2, “Features,” page 2-2

• Section 2.3, “Description,” page 2-3

• Section 2.4, “Integrated Mirroring Firmware,” page 2-5

• Section 2.5, “Fusion-MPT Support,” page 2-8

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 provides data protection for the system boot volume to safeguard critical information such as the operating system on servers and high performance workstations. This new Integrated Mirroring feature gives customers a robust, highperformance, fault-tolerant solution that is less expensive than a dedicated RAID controller.

The IM feature provides simultaneous mirroring on conﬁgurations of two to six disk disks, to assure fault tolerant, high availability data. If a disk fails, the hot swap capability allows the system to be easily restored by simply swapping disks. The system then automatically re-mirrors the swapped disk. Additionally, the hot spare feature keeps one disk ready to automatically replace a failed disk in the volume, making the system even more fault-tolerant.

Integrated RAID User’s Guide 2-1

Page 16

2.2 Features

The IM feature uses the same device drivers as the standard FusionMPT 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 a mirrored volume.

The IM feature is currently available as an optional component of the new Fusion-MPT architecture on all LSI Logic Ultra320 SCSI integrated I/O controller products.

This section lists the key features of Integrated Mirroring.

• Supports conﬁgurations of two to six mirrored disks on the same

channel

• Mirrored volume runs in optimal mode or degraded mode (that is, if

one mirrored disk fails)

• (Optional) Supports conﬁguration of a hot spare

• Hot swap capability

• Presents a single virtual drive to the OS

• Support for disks of different types and capacities

• Fusion-MPT architecture

• Easy-to-use BIOS-based conﬁguration utility (and DOS-based

conﬁguration utility for manufacturing use only)

• Support for greater volume capacity by integrating more disks

• Error notiﬁcation

– OS-speciﬁc event log – Errors displayed on CIM browser

• SAF-TE drive status LED support for Integrated Mirroring disks

• Write journaling, which allows automatic synchronization of

potentially inconsistent data after unexpected power-down situations

• Meta data used to store volume conﬁguration on mirrored disks

• Automatic background resynchronization while host I/Os continue

• Media veriﬁcation

2.3 Description

The LSI Logic Integrated Mirroring (IM) feature provides mirroring for the boot volume, as shown in Figure 2.1. This is accomplished through the ﬁrmware of an LSI Logic controller that supports the standard FusionMPT 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.

Mirroring can also be conﬁgured with up to 6 mirrored disks, or 5 mirrored disks and a hot spare. Figure 2.3 shows the logical view and physical view of the mirroring conﬁguration with more than two disks in the mirrored volume. Each “mirrored stripe” is written to a disk and is mirrored to an “adjacent” disk. This is commonly referred to as RAID 1E.

environment. (A DOS-based conﬁguration utility is also provided for manufacturing use only.)

2.4 Integrated Mirroring Firmware

This section describes features of the LSI Logic Integrated Mirroring (IM) ﬁrmware.

2.4.1 Host Interface

The IM host interface uses the “Message Passing Interface” as described in the Fusion-MPT speciﬁcation, including Integrated Mirroring of SCSI host adapters. Through the Fusion-MPT interface, the host OS has access to the logical IM drive as well as the physical disks. This allows support for domain validation and Ultra320 SCSI expander conﬁguration.

2.4.2 Resynchronization with Concurrent Host I/O Operation

The IM ﬁrmware uses queue tagged I/Os to allow SCSI I/Os to continue on the IM volume while the volume is being re-synchronized in the background. The host driver may optionally suspend the resynchronization operation while performing domain validation or while conﬁguring Ultra320 SCSI expanders. Resynchronization is attempted after the ﬁrmware has been reset, or after a “hot swap” has occurred to one of the physical IM disks.

The IM volume can be partially resynchronized, if the logging information in NVSRAM indicates that this is necessary. It usually takes less than a second for the ﬁrmware to complete a partial resynchronization. Like full synchronization, partial resynchronization is performed in the background.

2.4.3 Meta Data Support

The ﬁrmware supports Meta data describing the IM logical drive conﬁguration stored on each member disk. When the ﬁrmware is initialized, each member disk is queried to read the stored Meta data for consistency checking. The usable disk space for each IM member disk is adjusted down to leave room for this data.

Integrated Mirroring Firmware 2-5

Page 20

2.4.4 Hot Swap

The IM ﬁrmware supports hot swapping. The hot-swapped disk is automatically resynchronized in the background, without any host or user intervention. The hot-swapped disk must be at the same physical SCSI ID as one of the physical disks conﬁgured in the IM volume. 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 IM 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 IM member disks. Mode 6 SMART requires each physical disk to be polled once per minute. If a SMART ASC/ASCQ code is detected on a physical IM disk, the ﬁrmware processes the SMART data, and the last received SMART ASC/ASCQ is stored in non-volatile memory. The IM volume does not support SMART directly, since it is just a logical representation of the physical disks in the volume.

2.4.6 Floating Hot Spare

One disk can be conﬁgured as the ﬂoating hot spare disk. 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 SCSI ID of the failed disk is periodically polled to determine if the disk has been replaced. If so, the ﬁrmware automatically establishes that disk as the new “ﬂoating hot spare.”

2-6 Integrated Mirroring (IM) Overview

Page 21

2.4.7 Media Veriﬁcation

The IM ﬁrmware supports a background media veriﬁcation feature that runs once per minute when the IM volume is in optimal mode. The media veriﬁcation feature issues a SCSI Verify command to a segment of the disk. If the 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 SCSI ID Assignment

A single logical drive is presented as the combination of a set of physical member disks. Each individual member disk is hidden and returns a “selection timeout” when accessed. The SCSI Target ID of the IM logical drive is assigned when the logical drive is created. The lowest SCSI ID of the selected disks is used.

2.4.9 Disk Write Caching

The IM ﬁrmware disables disk write caching. 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.

2.4.10 NVSRAM Usage

IM ﬁrmware requires a 32 Kbyte NVSRAM in order to perform write journaling. Write journaling is used to verify that the mirrored disks in the IM volume are synchronized with each other. The NVSRAM also stores additional code and data used for error and exception handling, and it stores IM conﬁguration information during serial EEPROM updates. The disk write log uses approximately 4 Kbytes of the NVSRAM.

Integrated Mirroring Firmware 2-7

Page 22

2.5 Fusion-MPT Support

The LSI Logic Fusion-MPT architecture provides the interface to the SCSI chip/ﬁrmware to allow Integrated Mirroring.

2.5.1 BIOS ROM

The BIOS uses the Fusion-MPT interface to communicate to the SCSI chip/ﬁrmware to allow Integrated Mirroring. This includes reading the Fusion-MPT conﬁguration to gain access to the SCSI parameters that are used to deﬁne behavior between the adapter and its devices.

2.5.2 OS Drivers

The Fusion-MPT drivers for all supported operating systems implement the Fusion-MPT interface to communicate with the SCSI chip/ﬁrmware. To allow Integrated Mirroring, the host OS driver implements domain validation and supports Ultra320 expander conﬁgurations.

Chapter 3 Setting Up Integrated Mirroring

This chapter describes how to set up Integrated Mirroring (IM) using the BIOS-based conﬁguration utility (CU). The chapter includes these topics:

• Section 3.1, “IM Conﬁguration Overview”

• Section 3.2, “Conﬁguring IM with the BIOS-Based CU”

• Section 3.3, “Troubleshooting,” page 3-14

3.1 IM Conﬁguration Overview

The following constraints were made in order to simplify the IM conﬁguration.

• The BIOS-based CU allows you to create one mirrored volume per

Fusion-MPT controller.

• The mirrored volume can have two to six disks, or two to ﬁve disks

if an optional hot spare disk is used.

• Disks in a mirrored volume must be connected to the same channel

of the same Fusion-MPT controller, and the controller must be in the BIOS boot order.

• Disks in an IM volume must be non-removable, single-LUN disks that

support 512-byte sectors, wide synchronous transfers, Qtag’d I/Os, and a unit serial number. The disks must support SMART, and they must be minimally compliant with the SCSI-2 standard.

• Disks of different size are allowed in mirrored volumes, but the

smallest disk determines the “logical” size of each disk in the volume. The excess space of larger member disks is not used.

Integrated RAID User’s Guide 3-1

Page 24

3.2 Conﬁguring IM with the BIOS-Based CU

The BIOS-based conﬁguration utility (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 utility. After you do this, the message changes to:

“Please wait, invoking LSI Logic Configuration Utility...”

3.2.1 Quick IM Conﬁguration Procedure

Follow the steps below to conﬁgure an Integrated Mirroring (IM) volume with the BIOS-based CU. For a more complete explanation of this procedure, including detailed descriptions of the conﬁguration screens, see Section 3.2.3, “Detailed IM Conﬁguration Procedure,” page 3-5.

The conﬁguration procedure assumes that the system already has the required SCSI controller(s) and disks. You can conﬁgure one IM volume per Fusion-MPT controller.

1. On the Main menu screen of the BIOS-based CU, use the arrow keys to select an adapter.

2. Press Enter to go to the Adapter Properties screen.

3. On the Adapter Properties screen, use the arrow keys to select RAID Properties on the screen.

4. Press Enter to go to the RAID Properties screen. Continue with step 5 to conﬁgure a two-disk mirrored volume. Skip to step 6 to conﬁgure a mirrored volume with three to six disks.

5. To conﬁgure a two-disk mirrored volume, with an optional hot spare disk:

a. In the RAID Properties screen, use the arrow keys to select the

primary disk for the IM volume (the disk with the data you want to mirror).

b. Use the arrow keys to move to the Array Disk column for this

disk, and use the + and - keys to select Yes as the value.

c. When the “Keep Data/Erase Disk” message appears, press F3

to keep the data that is currently on this disk. The value in the Array Disk column changes to Primary.

3-2 Setting Up Integrated Mirroring

Page 25

d. Use the arrow keys to select the secondary (mirrored) disk for

the IM volume. Select Yes as the value for the Array Disk column.

If partitions are deﬁned on this disk, a message warns you that data on the disk will be lost when the mirrored volume is created. Press Delete to conﬁrm erasing data from the disk, or press any other key to deselect the disk. Continue with step 7.

6. To conﬁgure a mirrored volume with three to six disks, or three to ﬁve disks with an optional hot spare disk:

a. In the RAID Properties screen, use the arrow keys to select the

ﬁrst disk for the IM volume.

b. Use the arrow keys to move to the Array Disk column for this

disk, and use the + and - keys to select Yes as the value.

c. When the “Keep Data/Erase Disk” message appears, press

Delete to erase the disk.

d. Use the arrow keys to select the next disk for the IM volume.

Select Yes as the value for the Array Disk column. If partitions are deﬁned on this disk, a message warns you that

data on the disk will be lost when the mirrored volume is created. Press Delete to conﬁrm erasing data from the disk, or press any other key to deselect the disk.

e. Repeat the previous step to select up to four more disks for the

IM volume. (Or select up to three more disks if you want to conﬁgure a hot spare disk for the volume.)

7. (Optional) Use the arrow keys to select a hot spare disk for the IM volume. Select Yes as the value for the Hot Spare column.

8. When you have selected all disks for the IM volume, press Esc and select Save changes, then exit this menu. (If you do not want to create the IM volume, select Discard changes, then exit this menu.)

The IM volume exists as soon as you save the changes. The RAID Properties screen now displays the IM volume properties and status.

3.2.3 Detailed IM Conﬁguration Procedure

This section provides more detail on the BIOS-based CU screens that are used to conﬁgure an IM volume. See Section 3.2.4, “Other BIOS-

Based CU Screens,” page 3-11 for descriptions of the other BIOS-based

CU screens that are not used for this task.

Conﬁguring a two-disk mirrored volume –

Use the arrow keys to select the primary disk for the IM volume (the disk with the data you want to mirror). Use the arrow keys to move to the Array Disk column for this disk, and use the + and - keys to select Yes as the value.

When the “Keep Data/Erase Data” message appears, press F3 to keep the data that is currently on this disk. The value in the Array Disk column changes to Primary.

Use the arrow keys to select the secondary (mirrored) disk for the IM volume. Select Yes as the value for the Array Disk column. If partitions are deﬁned on this disk, a message warns you that data on the disk will be lost when the mirrored volume is created. Press Delete to conﬁrm erasing data from the disk, or press any other key to deselect the disk.

(Optional) Use the arrow keys to select a hot spare disk for the IM volume. Select Yes as the value for the Hot Spare column.

Press Esc and select Save changes, then exit this menu. (If you do not want to create the IM volume, select Discard changes, then exit this menu.) The IM volume is created when you save the changes, and synchronization of the mirrored disk(s) starts immediately.

Conﬁguring a mirrored volume with three to six disks –

Use the arrow keys to select the ﬁrst disk for the IM volume. Use the arrow keys to move to the Array Disk column for this disk, and use the + and - keys to select Yes as the value.

When the “Keep Data/Erase Data” message appears, press Delete to erase the disk.

Use the arrow keys to select the next disk for the IM volume. Select Yes as the value for the Array Disk column. If partitions are deﬁned on this disk, a message warns you that data on the disk will be lost when the mirrored volume is created. Press Delete to conﬁrm erasing data from the disk, or press any other key to deselect the disk.

Repeat the previous step to select up to four more disks for the IM volume. (Or select up to three more disks if you want to conﬁgure a hot spare disk for the volume.)

Page 31

(Optional) Use the arrow keys to select a hot spare disk for the IM volume. Select Yes as the value for the Hot Spare column.

Other RAID Properties Screen Information –

After the IM volume is created, the SCSI ID ﬁeld shows which SCSI ID the operating system uses to access the IM volume. This addressing information stays the same unless the volume is reconﬁgured with disks that have different SCSI IDs. The IM volume addressing information will also change if the SCSI ID is changed for the physical disk whose SCSI ID is being used for the IM volume.

The Size ﬁeld shows the capacity of the IM volume. The volume size is slightly less than half of the combined capacity of the mirrored disks, because the utility rounds the size down to increase compatibility in case a disk of the volume must be replaced. (Even if replacement disks are of the same size class, they may differ slightly in actual capacity.)

You can use the RAID Properties screen to reconﬁgure the IM volume after it has been created. You can change the disks in the IM volume back to standard disks by changing the values under the Array Disk column to No. When this is done, the virtual IM volume is “turned off” and the operating system can see the physical disks. You can do this if you no longer want the mirrored volume.

The screen shows the properties and status of each disk in the IM volume. The Status ﬁeld may show any of these values: OK, disk missing, incompatible, ofﬂine, out of sync,ordisk initializing.

The Predict Failure ﬁeld displays SMART information. A SMART enabled disk can predict when the disk is about to fail. When Yes appears in this column (failure is predicted), the disk should be replaced.

Figure 3.5 shows an example of the RAID Properties screen after a two-

disk IM volume with a hot spare has been conﬁgured.

The RAID Properties screen shows information about one IM volume at a time. Only one volume can be active at a time. Here is an explanation of the menu options on the screen in Figure 3.5.

• Select <Next Array> to display the next array (IM volume) on the

same SCSI channel.

Note: Although you cannot directly conﬁgure a second IM volume

on the same SCSI channel or Fusion-MPT controller, you could take the member disks of a volume from another controller and connect them to this controller. Then the ﬁrmware would detect two IM volumes on the same controller.

• Select <Delete Array> to delete the IM volume currently displayed

on the screen. The member disks will be converted back to standalone disks.

• Select <Add/Delete Hot Spare> to add a hot spare if the volume

does not already have one or to delete a hot spare if the volume does have one. If you are adding a hot spare, the CU redisplays the RAID Properties screen with only the applicable choices in the Hot Spare column enabled.

• Select <Activate Array> to make this IM volume the active array

(volume) on the system. Activating an array deactivates all other arrays on the Fusion-MPT controller.

3.2.4 Other BIOS-Based CU Screens

The BIOS-based CU screens described in this section are not directly used to conﬁgure an IM volume.

The SCSI BIOS saves information on the adapters shown in the top list into non-volatile memory. On the next boot, this information is used to determine which disk or IM volume to boot.

The cursor starts on the top adapter in the top list. Follow these steps to add an adapter to the top list:

1. Press the Insert key to move the cursor to the bottom adapter list.

2. Use the up and down arrows to select the desired adapter.

3. When the cursor is highlighting an adapter that is connected to a disk you want to use for the IM boot volume, press Enter.

3.3 Troubleshooting

The following sections provide some suggestions for troubleshooting.

3.3.1 RAID Properties Menu Item Disabled

Problem: The RAID Properties menu item is disabled Solution: Check the following:

• Is the adapter in the boot adapter list?

• Does the LSI adapter have Integrated Mirroring (IM) ﬁrmware?

• Is an IM volume already created on each Fusion-MPT adapter in the

system?

• Is “Disable Integrated RAID” set to Yes in the Global Properties

screen?

• Are there at least two disks on the selected SCSI bus?

3.3.2 IM Volume Uses Extra SCSI ID

Problem: The IM volume with two mirrored disks uses an extra SCSI ID

off the bus (that is, none of the physical disks of the IM volume has the same SCSI ID as the IM volume), and the conﬁguration utility won't allow the disk at the ID currently deﬁned as the volume ID to be conﬁgured.

Solution: To change the IM volume conﬁguration so it does not use an extra SCSI ID but also keeps the same volume ID, do the following:

1. Go to the RAID Properties screen. Note which SCSI ID the primary disk is using and which SCSI ID the volume is using. Also note the SCSI IDs of the remaining disks of the IM volume.

2. Set the IM volume disks to "No" and save the conﬁguration (in other words, break the volume).

3. Return to the RAID Properties screen and reconﬁgure the IM volume as follows:

– Primary disk at same ID as before – Secondary disk at ID used previously by the volume – Hot spare at SCSI ID used previously by the secondary disk

3-14 Setting Up Integrated Mirroring

Page 37

4. Save the conﬁguration by pressing Esc and following the on-screen instructions. This creates the IM volume and triggers an automatic resync.

3.3.3 Conﬁguration Utility Disables Selection of Disk

Problem: The conﬁguration utility does not allow a disk to be selected

for an IM volume. Solution: To determine why the disk cannot be selected, press F4 on

the RAID Properties screen to display diagnostic codes for each disk under the Size column. Code deﬁnitions are as follows:

0 Good status 1 Could not get serial number from disk 2 Can’t conﬁrm that disk has SMART capability 3 Maximum disks already conﬁgured for volume 4 Inquiry data returned says disk does not support wide, qtags,

disconnects, or sector size is not 512 bytes

5 User disabled qtags or Disconnects for disk on device properties

screen

6 Partitions on disk exceed size that can be mirrored by an already

selected secondary or hot spare disk

7 Disk is not large enough to mirror partitions contained on selected

primary disk

8 Hot spare detected while no IM volume exists. Must delete hot

spare and save that conﬁguration

9 Disk partition uses some or all of the last 32 sectors of the disk

(16 Kbytes). The last 32 sectors are required for IR (Integrated

RAID) internal processing. 10 Disk has sector size other than 512 bytes 11 Device is not a compatible device type. Must be non-removable

disk. 12 Hot Spare too small to mirror volume 13 Maximum disks already conﬁgured for volume

Chapter 4 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”

• Section 4.2, “IS Features”

• Section 4.3, “IS Description”

• Section 4.4, “Integrated Striping Firmware”

• Section 4.5, “Fusion-MPT Support,” page 4-5

4.1 Introduction

The LSI Logic Integrated Striping (IS) feature is targeted at applications that require the faster performance and increased storage capacity of striping. The IS feature is a low-cost solution with many of the features 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 host adapter ﬁrmware that supports the Fusion-MPT Interface. IS provides better performance and more capacity than individual SCSI disks without burdening the host CPU. The ﬁrmware splits host I/Os over multiple disks and presents the disks as a single logical drive, which appears as a physical device. In general, striping is transparent to the BIOS, drivers, and operating system.

The Fusion-MPT BIOS Conﬁguration Utility (CU) is used to conﬁgure the IS volume, which can use from two to six disk disks. The BIOS and drivers support SCSI Domain Validation to the physical member disks associated with a striped logical drive. Host-based CIM software monitors the state of the physical disks and reports error conditions as they arise.

Integrated RAID User’s Guide 4-1

Page 40

4.2 IS Features

Following is a list of some key features of Integrated Striping:

• Striping with 2 to 6 disks on the same channel, allowing greater

• A single virtual drive is presented to the OS

• Support for disks of different types and capacities

• Fusion-MPT architecture

• Easy-to-use BIOS-based conﬁguration utility (and DOS-based

• Error notiﬁcation

• Meta data is used to store volume conﬁguration on disks

• OS-speciﬁc event log

• Error display on CIM browser

• SAF-TE drive status LED support for IS disks

• Support for domain validation

• Supports fresh install only - no migration of data on an existing disk

volume capacity

conﬁguration utility for manufacturing use only)

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, etc. When the system reaches the end of the disk list, it starts writing 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.

IS Description 4-3

Page 42

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 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. This allows support for domain validation and Ultra320 SCSI expander conﬁguration.

4.4.2 Meta Data Support

The ﬁrmware supports Meta data describing the IS logical drive conﬁguration stored on each member disk. When the ﬁrmware is initialized, each member disk is queried to read the stored Meta data for consistency checking. 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 once per minute. 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 SCSI ID Assignment

A single logical drive is presented as the combination of a set of physical member disks. Each individual member disk is hidden and returns a “selection timeout” when accessed. The SCSI Target ID of the IS logical drive is assigned when the logical drive is created. The lowest SCSI ID of the selected disks is used.

4-4 Integrated Striping (IS) Overview

Page 43

4.4.5 Disk Write Caching

Disk write caching is enabled in IS volumes.

4.5 Fusion-MPT Support

The LSI Logic Fusion-MPT architecture provides the interface to the SCSI chip/ﬁrmware to allow Integrated Striping.

4.5.1 BIOS ROM

The BIOS uses the Fusion-MPT interface to communicate to the SCSI chip/ﬁrmware to allow Integrated Striping. This includes reading the Fusion-MPT conﬁguration to gain access to the SCSI parameters that are used to deﬁne behavior between the adapter and its devices.

4.5.2 OS Drivers

The Fusion-MPT drivers for all supported operating systems implement the Fusion-MPT interface to communicate with the SCSI chip/ﬁrmware. To allow Integrated Striping, the host OS driver implements domain validation and supports Ultra320 expander conﬁgurations.

Chapter 5 Setting Up Integrated Striping

This chapter describes how to set up Integrated Striping (IS) using the BIOS-based conﬁguration utility (CU). The chapter includes these topics:

• Section 5.1, “IS Conﬁguration Overview”

• Section 5.2, “Conﬁguring IS with the BIOS-Based CU”

• Section 5.3, “Troubleshooting,” page 5-11

5.1 IS Conﬁguration Overview

The following restrictions were made in order to simplify the IS conﬁguration.

• The BIOS-based CU allows you to create one Integrated Striped

volume per Fusion-MPT controller.

• An IS volume can have from two to six disks.

• Disks in an IS volume must be non-removable, single-LUN disks that

support 512-byte sectors, wide synchronous transfers, Qtag’d I/Os, and a unit serial number. The disks must support SMART, and they must be minimally compliant with the SCSI-2 standard.

• Disks in an IS volume must be connected to the same channel of the

same Fusion-MPT controller, and the controller must be in the BIOS boot order.

• Disks of different size are allowed in IS volumes, but the smallest

disk determines the “logical” size of each disk in the volume. The excess space of larger member disks is not used.

• Usable disk space for each IS member disk is adjusted down to

leave room for Meta data. Usable disk space may be further reduced to maximize the ability to interchange disks in the same size classiﬁcation.

Integrated RAID User’s Guide 5-1

Page 46

• The supported stripe size is 64 Kbytes.

“Please wait, invoking LSI Logic Configuration Utility...”

5.2.1 Quick IS Conﬁguration Procedure

Follow the steps below to conﬁgure an Integrated Striping (IS) volume with the BIOS-based CU. For a more complete explanation of this procedure, including detailed descriptions of the conﬁguration screens, see Section 5.2.3, “Detailed IS Conﬁguration Procedure,” page 5-4.

The conﬁguration procedure assumes that the system already has the required SCSI controller(s) and disks. You can conﬁgure one IS volume per Fusion-MPT controller.

1. On the Main menu screen of the BIOS-based CU, use the arrow keys

to select an adapter.

2. Press Enter to go to the Adapter Properties screen.

3. On the Adapter Properties screen, use the arrow keys to select RAID

Properties on the screen.

4. Press Enter to go to the RAID Properties screen.

5. In the RAID Properties screen, use the arrow keys to select the ﬁrst

disk for the IS volume. Use the arrow keys to move to the Array Disk column for this disk, and use the + and - keys to select Yes as the value for this column.

If partitions are deﬁned on the selected disk, a message appears warning you that data on the disk will be lost when the striped volume is created. You can then deselect that disk, if desired, or erase the disk and continue.

6. Repeat the previous step to select up to ﬁve more disks for the

striped volume.

5-2 Setting Up Integrated Striping

Page 47

If partitions are deﬁned on the selected disks, a message appears warning you that data on the disk will be lost when the striped volume is created. You can then deselect that disk, if desired, or erase the disk and continue.

7. When you have selected all disks for the IS volume, press Esc and

select Save changes, then exit this menu. (If you do not want to create the volume, select Discard changes, then exit this menu.)

The IS volume exists as soon as you save the changes. The RAID Properties screen now displays the IS volume properties and status.

Repeat the previous step to select up to ﬁve more disks for the IS volume. If partitions are deﬁned on these disks, a message appears warning you that data on the disk will be lost when the striped volume is created. You can then deselect that disk, if desired, or continue and delete the data.

When you have selected all disks for the IS volume, press the Esc key and select Save changes, then exit this menu. (If you do not want to create the IS volume, select Discard changes, then exit this menu instead.) The IS volume is created when you save the changes.

Other RAID Properties Screen Information –

After the IS volume is created, the SCSI ID ﬁeld shows which SCSI ID the operating system uses to access the volume. This addressing information stays the same unless the volume is reconﬁgured with disks that have different SCSI IDs. The IS volume addressing information will also change if the SCSI ID is changed for the physical disk whose SCSI ID is being used for the IS volume.

The Size ﬁeld shows the capacity of the IS volume. Each disk’s properties are shown along with its status. The Status ﬁeld

may show any of these values: OK, disk missing, incompatible, ofﬂine,orinitializing.

Figure 5.5 shows an example of the RAID Properties screen after a

three-disk IS volume has been conﬁgured.

5.3 Troubleshooting

The following sections provide some suggestions for troubleshooting.

5.3.1 RAID Properties Menu Item Disabled

Problem: The RAID Properties menu item is disabled Solution: Check the following:

• Is the adapter in the boot adapter list?

• Does the LSI adapter have Integrated Striping (IS) ﬁrmware?

Troubleshooting 5-11

Page 56

• Is an IS volume already created on each Fusion-MPT adapter in the

system?

• Is “Disable Integrated RAID” set to Yes in the Global Properties

screen?

• Are there at least two disks on the selected SCSI bus?

5.3.2 Conﬁguration Utility Disables Selection of Disk

Problem: The conﬁguration utility does not allow a disk to be selected

for an IS volume. Solution: To determine why the disk cannot be selected, press F4 on

the RAID Properties screen to display diagnostic codes for each disk under the Size column. Code deﬁnitions are as follows:

disconnects, or sector size is not 512 bytes 5 User disabled qtags or Disconnects for disk on device properties

Appendix A Using the DOS-Based Conﬁguration Utility

This appendix describes how to use the DOS-based conﬁguration utility (CU) to create Integrated Mirroring (IM) and Integrated Striping (IS) volumes. Although the same utility is used to set up both IM and IS volumes, the two kinds of conﬁguration are explained in separate sections (A.4 and A.5). This is done because IM conﬁguration and IS conﬁguration use somewhat different command line options and have different default settings.

The appendix includes these topics:

• Section A.1, “Conﬁguration Overview”

• Section A.2, “Running the DOS-Based CU”

• Section A.3, “Rules for Command Line Options”

• Section A.4, “Conﬁguring an IM Volume with the DOS-Based CU”

• Section A.5, “Conﬁguring an IS Volume with the DOS-Based CU”

Note: The DOS-based CU is intended for use only in the manu-

facturing environment. End users can use the BIOS-based

conﬁguration utility to create IM and IS volumes. (See

Chapter 3, “Setting Up Integrated Mirroring” and Chapter 5, “Setting Up Integrated Striping”.)

A.1 Conﬁguration Overview

The following general information applies to creating both IM and IS volumes with the DOS-based CU.

• Only one IM or IS volume can be created per Fusion-MPT controller.

• An IM or IS volume can have two to six disks. (An IM volume can

have from two to ﬁve disks if an optional hot spare disk is used.)

Integrated RAID User’s Guide A-1

Page 68

• Member disks of an IM or IS volume must be connected to the same

channel of the same Fusion-MPT controller, and the controller must be in the BIOS boot order.

• Member disks must be non-removable, single-LUN disks that support

512-byte sectors, wide synchronous transfers, Qtag’d I/Os, and a unit serial number. The disks must support SMART, and they must be minimally compliant with the SCSI-2 standard.

• Member disks can be of different sizes, but the smallest disk

determines the “logical” size of each disk in the volume. The excess space of larger member disks is not used.

• The usable disk space for each volume member disk is adjusted

down to leave room for Meta data. Usable disk space may be further reduced to maximize the ability to interchange disks in the same size classiﬁcation.

• Default settings are provided for all modiﬁable ﬁelds. (See Section

A.4.3, “IM Parameter Defaults for Fusion-MPT SCSI Controllers,” page A-7 and Section A.5.3, “IS Parameter Defaults for Fusion-MPT SCSI Controllers,” page A-13.)

A.2 Running the DOS-Based CU

The name of the DOS-based CU executable ﬁle is mptpsir.exe. Follow these steps to run the utility:

Note: You cannot run mptpsir in a virtual DOS window from

within Windows.

1. Copy mptpsir.exe to a DOS bootable diskette that also contains dos4gw.exe.

2. Insert the diskette into drive "a:" and boot the system to the DOS prompt a:\>

3. Type mptpsir followed by the desired command line options, then press Enter.

After it executes the command line options, the DOS-based CU displays status messages that indicate whether the conﬁguration completed successfully.

A-2 Using the DOS-Based Conﬁguration Utility

Page 69

The DOS-based CU can use DOS input redirection to read conﬁguration commands from a ﬁle speciﬁed on the command line. It can also use DOS output redirection to write status messages to a ﬁle instead of displaying them on the monitor.

A.3 Rules for Command Line Options

Here are some general rules for using the DOS-based CU command line options:

• Each command line must start with mptpsir and must include at

least one option.

• No spaces are allowed between an option and an option value.

• A slash (/) cannot be used for an option value.

• The /i option must be used for DOS input redirection, and the /o

option must be used for DOS output redirection. When using DOS input redirection, command line options must be entered in a ﬁle as a contiguous block of text, with no inserted carriage returns.

• The same option cannot be disabled and enabled on the same

command line.

• The delete (/d) option cannot be used at the same time as an option

to create a volume.

A.4 Conﬁguring an IM Volume with the DOS-Based CU

There are several ways to create an IM volume with the DOS-based CU (Create options are explained in Section A.4.1.1, and speciﬁc command line examples are included in Section A.4.4, “Examples of Command

Line Usage,” page A-8):

• Have the CU create the volume automatically (/a option).

• Create a “custom” two-disk mirrored volume by specifying a SCSI

controller (/c option) and the SCSI target IDs of two or three disks (/t option for each disk - the optional third disk is the hot spare).

Rules for Command Line Options A-3

Page 70

• Create a “custom” three- to six-disk mirrored volume, including an

optional hot spare (/rte option, followed by /c for SCSI controller and /t for each disk).

Note: You must list the /rte option ﬁrst to indicate that the volume

will have three or more mirrored disks.

A.4.1 Command Line Options

This section lists and explains all the DOS-based CU command line options that are used to create, delete, and reconﬁgure an IM volume.

See Section A.4.4, “Examples of Command Line Usage,” page A-8,for examples of how to create various IM conﬁgurations.

A.4.1.1 Create Options

/c – SCSI controller number. Same as boot adapter order number. You

can get the order number from the MPTBIOS banner that appears during boot. The controller number (order number) appears in the HBA column.

/t – SCSI target ID. For a three-disk conﬁguration, ﬁrst /t is primary

disk, second is secondary disk, third is optional hot spare. The hot spare is always speciﬁed as the last /t option.

/hs – Hot spare. The value of the last /t option speciﬁed is the SCSI ID

designated as the hot spare.

/rte – Raid type. Use this option only if you are creating a mirrored

volume with three to six mirrored disks (or three to ﬁve mirrored disks and a hot spare disk). Do not use this option if you are creating a mirrored volume with two mirrored disks and an optional hot spare disk.

/sz – IM volume size (Mbytes), up to 2097151 Mbytes /so – Volume settings override, 1 to 4 hex digits. This option applies to

the current volume only. See Section A.4.1.7, “Volume Setting

Deﬁnitions.”

A-4 Using the DOS-Based Conﬁguration Utility

Page 71

/ad – Action data, 1 to 4 hex digits. This option changes the default

create volume behavior. The Action data deﬁnitions are: 0x0001 - Do not initialize disks when volume is created. 0x0002 - Low-level initialization. Zero initialize beginning and end

/a – Automatic create. Creates an IM volume with one primary disk

and one secondary mirrored disk, using disks on the lowest numbered Fusion-MPT controller with at least two disks that don’t have deﬁned partitions. If more than two disks are found without partitions on a given controller, the two disks with the lowest SCSI IDs are used. The lowest SCSI ID of the selected disks is used for the IM volume ID. (This option does not create a hot spare disk.)

/ss – Skip synchronization during IM volume creation

A.4.1.2 Erase Disk Options

/e – Erase a speciﬁed disk, using the /t and /c options /eall – Erase all disks on the desired SCSI bus, using the /c option

of disks in volume.

A.4.1.3 DOS Redirection Options

/i – Use DOS Standard In redirection /o – Use DOS Standard Out redirection

A.4.1.4 Existing Volume Options

/rd – Disable resynchronization. Disables resynchronization by taking

the secondary disk ofﬂine. This operation remains in effect until the system is rebooted. If the system is rebooted, a resynchronization will start. So this option must be used together with the No Reboot option (/nr).

/re – Enable resynchronization. Brings the secondary disk back online,

which starts a resynchronization.

/d – Delete mirrored volume. If deleting a hot spare from the volume,

use the /t option.

Conﬁguring an IM Volume with the DOS-Based CU A-5

Page 72

A.4.1.5 Changing Defaults for Newly Created Volumes

/vi – Vendor Identiﬁcation (logical drive inquiry data) - 8 ASCII

characters required

/pi – Product Identiﬁcation (logical drive inquiry data) - 16 ASCII

characters required

/pr – Product Revision (logical drive inquiry data) - 4 ASCII characters

required

/io – Offsetwithin inquiry data to start saving in non-volatile memory for

later access. Two offsets can be speciﬁed, but each instance of this option requires the /is option. One possible use of this option is to save FRU data for the drive.

/is – Size, in bytes, to save in non-volatile memory of inquiry data from

offset given in the /io option.

/vs – Set the VolumeSettings parameter (1- to 4-digit hex number). See

Section A.4.1.7, “Volume Setting Deﬁnitions.”

A.4.1.6 Miscellaneous Options

/? – Display available Help options /h – Display available Help options /nr – No automatic reboot after exit. Do not access disks connected to

LSI SCSI host adapters until after reboot, except for running this utility again.

A.4.1.7 Volume Setting Deﬁnitions

One hexadecimal number replaces the settings of all the options below when using either the /vs or /so options.

0x0001 – Write Caching Enabled 0x0002 – Take Physical Drive Off-Line on SMART Error 0x0004 – Autoconﬁgure Hot-Swap Drives

A-6 Using the DOS-Based Conﬁguration Utility

Page 73

0x0008 – High Priority Resync Enabled 0x0010 – Enable ﬁrmware to replace last two bytes of Product ID in

inquiry data when an inquiry is sent to the IM volume’s logical drive.

A.4.2 Making Manufacturing Settings Read Only

You can make the manufacturing settings read-only by changing the PageType ﬁeld for the Fusion-MPT Conﬁguration Page, Manufacturing Page 4.

Important: Making this page read-only disables the /vi, /pi, /pr, /io, /is,

and /vs options. See the documentation for the nvdata program in the Fusion-MPT Device Management User’s Guide to ﬁnd out more about changing the PageType ﬁeld.

A.4.3 IM Parameter Defaults for Fusion-MPT SCSI Controllers

• Disk Write Cache DISABLED

• Volume ENABLED

• Disk Ofﬂine when SMART error DISABLED

• Auto-Conﬁgure Hot-Swap Drives ENABLED

• High Priority Resynchronization DISABLED

• Mirror Resynchronization ENABLED

• Product ID Sufﬁx ENABLED

• No Inquiry Data saved from IM disks

• Controller 0

• Size defaults to maximum allowable by disks selected, minus a disk

coercion factor. The disk coercion factor allows disks of different sizes within the same disk class to work for a mirrored volume.

• Logical DriveVendor ID: LSILOGIC

• Logical Drive Product ID: 1030 IM

• Logical Drive Revision ID: 0x1000

Page 74

A.4.4 Examples of Command Line Usage

This section shows how various DOS-based CU command line options are used for mirrored volumes.

A.4.4.1 Creating a Custom Mirrored Volume

At least two targets must be listed with the /t option. Other options can be used on the same command line as the create options, to override the defaults. Here are some examples:

Example 1 – Conﬁgure a mirrored pair of disks on adapter 1 with the primary disk at SCSI ID 1, the secondary disk at SCSI ID 4, and a hot spare at SCSI ID 5.

mptpsir /c1 /t1 /t4 /t5

Example 2 – Conﬁgure the IM volume the same as in Example 1, but limit the size to 1000 Mbytes and don’t reboot on exit.

mptpsir /c1 /t1 /t4 /t5 /sz1000 /nr

A.5 Conﬁguring an IS Volume with the DOS-Based CU

There are two basic ways to create an IS volume with the DOS-based CU (Create options are explained in Section A.5.1.1, and speciﬁc command line examples are included in Section A.5.4, “Examples of

Command Line Usage,” page A-13):

• Have the CU create the volume automatically (/a option).

• Create a “custom” two- to six-disk striped volume by specifying a

SCSI controller (/c option) and the SCSI target ID of each member disk (/t option for each disk).

Note: The stripe size for IS volumes is ﬁxed at 64 Kbytes.

A.5.1 Command Line Options

This section lists and explains all the DOS-based CU command line options that are used to create, delete, and reconﬁgure an IS volume.

See Section A.5.4, “Examples of Command Line Usage,” page A-13,for examples of how to create various IS conﬁgurations.

A.5.1.1 Create Options

/c – SCSI controller number. Same as boot adapter order number. You

can get the order number from the MPTBIOS banner that appears during boot. The controller number (order number) appears in the HBA column.

/t – SCSI target ID. Use a separate /t to specify each disk in the IS

volume.

/rts – Raid Type = striped. You must use the /rts option when creating

an IS volume.

/sz – IS logical drive size (Mbytes), up to 2097151 Mbytes /so – Volume settings override, 1 to 4 hex digits. This option applies to

the current volume only. See Section A.5.1.7, “Volume Setting

Deﬁnitions.”

Page 77

/ad – Action data, 1 to 4 hex digits. This option changes the default

create volume behavior. The Action data deﬁnitions are: 0x0001 - Do not initialize disks when volume is created. 0x0002 - Low-level initialization. Zero initialize beginning and end

/a – Automatic create - Creates an IS volume, using disks on the

lowest numbered Fusion-MPT controller with at least two disks that don’t have deﬁned partitions. Up to 6 disks are automatically selected for the IS volume. The lowest SCSI ID of the selected disks is used for the IS volume ID.

A.5.1.2 Erase Disk Options

/e – Erase a speciﬁed disk, using the /t and /c options /eall – Erase all disks on the desired SCSI bus, using the /c option

A.5.1.3 DOS Redirection Options

/i – Use DOS Standard In redirection /o – Use DOS Standard Out redirection

of disks in volume.

A.5.1.4 Existing Volume Options

/d – Delete striped conﬁguration

A.5.1.5 Changing Defaults for Newly Created Volumes

/vi – Vendor Identiﬁcation (logical drive inquiry data) - 8 ASCII

characters required

/pi – Product Identiﬁcation (logical drive inquiry data) - 16 ASCII

characters required

/pr – Product Revision (logical drive inquiry data) - 4 ASCII characters

required

/io – Offsetwithin inquiry data to start saving in non-volatile memory for

later access. Two offsets can be speciﬁed, but each instance of

Conﬁguring an IS Volume with the DOS-Based CU A-11

Page 78

this option requires the /is option. One possible use of this option is to save FRU data for the drive.

/is – Size, in bytes, to save in non-volatile memory of inquiry data from

offset given in the /io option.

/vs – Set the VolumeSettings parameter (1- to 4-digit hex number). See

Section A.5.1.7, “Volume Setting Deﬁnitions.”

A.5.1.6 Miscellaneous Options

/? – Display available Help options /h – Display available Help options /nr – No automatic reboot after exit. Do not access disks connected to

LSI SCSI host adapters until after reboot, except for running this utility again.

A.5.1.7 Volume Setting Deﬁnitions

One hexadecimal number replaces the settings of all the options below when using either the /vs or /so options.

0x0001 – Write Caching Enabled 0x0002 – Take Physical Drive Off-Line on SMART Error 0x0010 – Enable ﬁrmware to replace last two bytes of Product ID in

inquiry data when an inquiry is sent to the IR volume’s logical drive.

A.5.2 Making Manufacturing Settings Read Only

You can make the manufacturing settings read-only by changing the PageType ﬁeld for the Fusion-MPT Conﬁguration Page, Manufacturing Page 4.

Important: Making this page read-only disables the /vi, /pi, /pr, /io, /is,

and /vs options. See the documentation for the nvdata program in the Fusion-MPT Device Management User’s Guide to ﬁnd out more about changing the PageType ﬁeld.

A.5.3 IS Parameter Defaults for Fusion-MPT SCSI Controllers

• Disk Write Cache ENABLED

• Volume ENABLED

• Disk Ofﬂine when SMART error DISABLED

• Product ID Sufﬁx ENABLED

• No Inquiry Data saved from IS disks

• Controller 0

• Size defaults to maximum allowable by disks selected, minus a disk

coercion factor. The disk coercion factor allows disks of different sizes within the same disk class to work for a striped logical drive.

• Logical Drive Vendor ID: LSILOGIC

• Logical Drive Product ID: 1030 IS

• Logical Drive Revision ID: 0x1000

A.5.4 Examples of Command Line Usage

This section shows how various DOS-based CU command line options are used for striped volumes.

A.5.4.1 Creating a Custom Striped Logical Drive

At least two targets must be listed with the /t option. Other options can be used on the same command line as the create options, to override the defaults. Here are some examples:

Example 1 – Conﬁgure a striped volume with three disks on adapter 1, using the disks at SCSI IDs 1, 4, and 5.

mptpsir /rts /c1 /t1 /t4 /t5

Example 2 – Conﬁgure the IS logical drive the same as in Example 1, but limit the size to 1000 Mbytes and don’t reboot on exit.

mptpsir /rts /c1 /t1 /t4 /t5 /sz1000 /nr

Example 3 – Conﬁgure a striped volume with the characteristics speciﬁed in inputfile. (The command line options in c:\inputfile must be in a contiguous block of text with no inserted carriage returns.)

A.5.4.2 Deleting an IS Volume

Example 1 – Delete the IS volume.

mptpsir /rts /d

A.5.4.3 Erasing Disk(s)

Example 1 – Erase the disk with SCSI ID 5 on Controller 1.

mptpsir /rts /c1 /t5 /e

Example 2 – Erase all disks on Controller 2.

mptpsir /rts /c2 /eall

A.5.4.4 Replacing Manufacturing Defaults

Example 1 – Use OEM-speciﬁc vendor, product, and revision

information for the logical drive ID of the IS logical drive.
