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.

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.
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.
• 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.

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.
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.
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.
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.
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.
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.
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.
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.

Press F2 to move to the menu area. Select a menu item by moving the cursor to it with the right and left arrow keys and then pressing Enter.
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 BIOSBased CU Screens,” page 3-11 for descriptions of the other BIOS-based CU screens that are not used for this task. Note: Your system may have a different version of the FusionMPT BIOS. Therefore, the screens that you see may be slightly different from the examples shown here. 3.2.3.1 Main Screen Figure 3.
To configure an IM volume, use the arrow keys to select an adapter, and press Enter to go to the Adapter Properties screen. Note: You can also access the Global Properties screen and the Boot Adapter List screen by selecting the options in the menu area. (These screens are not used to define an IM volume.) For more information about them, see Section 3.2.4, “Other BIOS-Based CU Screens,” page 3-11. 3.2.3.
On the Adapter Properties screen, use the arrow keys to select RAID Properties and then press Enter to go to the RAID Properties screen, which is shown in Figure 3.4. After an IM volume is configured, you can select Synchronize Whole Mirror on the Adapter Properties screen to force a resynchronization of all blocks in the IM volume. The default is to resynchronize only the blocks that are out of sync in the volume, as indicated by log entries. 3.2.3.3 RAID Properties Screen Figure 3.
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.
(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.

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.
A.2 • 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.
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: A.4 • 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.
• 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: A.4.1 You must list the /rte option first to indicate that the volume will have three or more mirrored disks. 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.
/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 of disks in volume. /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.
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 – Offset within 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.
0x0008 – High Priority Resync Enabled 0x0010 – A.4.2 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. 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: A.4.3 Making this page read-only disables the /vi, /pi, /pr, /io, /is, and /vs options.
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.
A.4.4.3 Erasing Disk(s) Example 1 – Erase the disk with SCSI ID 5 on Controller 1. mptpsir /c1 /t5 /e Example 2 – Erase all disks on Controller 2. mptpsir /c2 /eall A.4.4.4 Replacing Manufacturing Defaults Example 1 – Use OEM-specific vendor, product, and revision information for the logical drive ID of the mirrored volume.
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).
/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 of disks in volume. /a – A.5.1.2 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.
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.
A.5.3 A.5.4 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.
mptpsir /rts /i < c:\inputfile 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.
