This appendix explains how to use the LSI Logic Fusion-MPT Serial Attached SCSI (SAS) BIOS Configuration Utility. This appendix contains the following sections:

• Fusion-MPT SAS BIOS Overview
• Starting the SAS BIOS Configuration Utility
• Configuration Utility Screens
• Performing RAID Configuration Tasks

---

F.1 Fusion-MPT SAS BIOS Overview

The Fusion-MPT SAS BIOS features include:

• Configuration for up to 256 adapters; any four can be chosen for INT13 (bootrom) support
• Support for Message Passing Technology (MPT)
• Support for the LSI53C1064 devices
• Support for SAS devices

• Support for Integrated RAID initialization (with proper firmware)

The SAS BIOS is the bootable ROM code that manages SAS hardware resources. It is specific to a family of LSI Logic Fusion-MPT SAS controllers or processors. The Fusion-MPT SAS BIOS integrates with a standard system BIOS, extending the standard disk service routine provided through INT13h.

During the boot time initialization, the SAS BIOS determines whether the system BIOS has already installed other hard disks, such as an IDE drive. If such drives are already installed, the SAS BIOS maps any SAS drives it finds behind these drives. Otherwise, the SAS BIOS installs drives starting with the system boot drive. In this case, the system boots from a drive controlled by the SAS BIOS. The LSI Logic SAS BIOS supports the BIOS Boot Specification (BBS).

F.1.1 Boot Initialization With BIOS Boot Specification (BBS)

The Fusion-MPT SAS BIOS supports the BIOS Boot Specification (BBS), which allows you to choose which device to boot from by selecting the priority.

To use this feature, the system BIOS must also be compatible with the BBS. If the system supports the BBS, you can use the system BIOS Setup menu to select the boot order and drive order. In the system BIOS Setup, the Boot Connection Devices menu lists the available boot options. Use that menu to select the device and rearrange the order. Then exit to continue the boot process.

---

F.2 Starting the SAS BIOS Configuration Utility

If you have SAS BIOS version 6.xx, and it includes the Fusion-MPT SAS BIOS Configuration Utility, you can change the default configuration of the SAS host adapters. You may decide to change these default values if there is a conflict between device settings or if you need to optimize system performance.

The version number of the SAS BIOS appears in a banner displayed on the computer monitor during bootup. If the utility is available, this message also appears during bootup:

Press Ctrl+C to start LSI Logic Configuration Utility...

This message remains on the screen for about five seconds, giving you time to start the utility. If you press Ctrl+C, the message changes to:

Please wait, invoking LSI Logic Configuration Utility...

After a brief pause, the computer monitor displays the Main menu of the Fusion-MPT SAS BIOS Configuration Utility. These messages may appear during the boot process:

• Adapter removed from boot order!

This message appears when an adapter was removed from the system or was relocated behind a PCI bridge.

• Adapter configuration may have changed, reconfiguration is suggested!

This message appears if none of the information in the NVRAM is valid.

• Updating Adapter List!

This message appears when fewer than four adapters are in the boot order and more adapters exist than are shown.

Caution - The SAS BIOS Configuration Utility is a powerful tool. If, while using it, you somehow disable all of the controllers, press Ctrl+E (or Ctrl+A on versions earlier than 5.00) after memory initialization during reboot to re-enable and reconfigure the controllers.

---

F.3 Configuration Utility Screens

All SAS BIOS Configuration Utility screens are partitioned into the following areas, starting at the top of the screen:

• Header Area: This area lists static information text, including the product title and version.
• Menu Area: This area lists the current screen title and controller information when on screens other than Adapter List.
• Main Area: This is the main area for presenting data. This area has a cursor for item selection, horizontal scrolling, and vertical scrolling. The horizontal and vertical scroll bars appear here if needed.
• Footer Area: This area provides general help information text.

F.3.1 User Input Keys

The general key inputs that are listed in TABLE F-1 apply on all screens of the SAS BIOS Configuration Utility.

F.3.2 Adapter List Screen

When you start the Fusion-MPT SAS BIOS Configuration Utility, the Adapter List screen (shown below) appears.. This screen displays a scrolling list of up to 256 LSI Logic SAS host adapters in the system and information about each of them. TABLE F-2 describes the fields in this screen.

Use the arrow keys to select an adapter, then press Enter to view and modify the selected adapter’s properties (and to access the other screens). After you select an adapter and press Enter, the adapter’s devices are scanned and the Adapter Properties Screen appears.

To change the Adapter boot order, use the -, +, Insert, and Delete keys while on the Boot Order field. Press Insert or Delete to add or remove an adapter to or from the boot order. Press the - and + keys to modify an adapter’s position in the boot order. If you make changes to the boot order, the Configuration Utility prompts you to save the changes before you exit the screen.

From the Adapter List screen (shown below), you can also press Alt+N to access the Global Properties screen. On this screen you can change global scope settings.

If the Logical Block Addresses (LBAs) can be reassigned, or need to be reassigned, the following prompt appears:

Reassign the block?
(Yes, No, All, nonE, Cancel)

The reassignment options are as follows:

• Yes: Reassign only this block. If another block needs to be reassigned in the future, display the prompt again.
• No: Do not reassign this block. If another block needs to be reassigned in the future, display the prompt again.
• All: Reassign the current block, and automatically reassign other blocks that need it, without displaying the prompt again.
• nonE: Do not reassign the current block, and do not automatically reassign any other blocks that need it. Do not display the prompt again.
• Cancel: Do not reassign anything, and stop the verification process.

F.3.11 Integrated RAID Configuration and Management Screens

Integrated RAID configuration and management involves many screens, all of which are accessed by selecting RAID Properties on the Adapter Properties Screen.

• If no RAID volumes are currently configured, you are asked to create a RAID volume.
• If at least one RAID volume is currently configured, you are shown the current volume(s) for management purposes.

The screens in the RAID configuration and management area are:

• Select New Array Type
• Create New Array
• View Array
• Manage Array

F.3.11.1 Select New Array Type Screen

Select the type of array to create, as shown below.

The two new array type options are described in the text that appears on the screen. No further explanation is needed.

F.3.11.2 Create New Array Screen

The Create New Array screen (shown below) allows you to select disks for a new array. TABLE F-10 describes the fields of the screen.

For an IM volume, when the first disk is added you are asked about the data on the disks. You have two options:

• Press M to keep the existing data and migrate to an IM array. Disk synchronization will occur.
• Press D to overwrite existing data, and create a new IM array. All data on all disks in the array will be deleted. No synchronization occurs.

After the volume is configured, press C to create the array. You are asked to save changes, which will create the array. After the array is created, the utility returns you to the Adapter Properties screen.

F.4 Performing RAID Configuration Tasks

This section contains the following information and instructions for using the Configuration Utility to set up RAID:

• RAID Implementation and Support
• Creating a RAID 0 Volume
• Creating a RAID 1 Volume
• Creating a Second RAID Volume
• Viewing RAID Volume Properties
• Managing Hot Spares
• Synchronizing an Array
• Activating an Array
• Deleting an Array
• Locating a Disk Drive

F.4.1 RAID Implementation and Support

The LSISAS1064 controller supports the Integrated RAID hardware solution, which is a highly integrated, low-cost RAID solution. It is designed for systems requiring redundancy and high availability, but not requiring a full-featured RAID implementation.

Integrated RAID includes Integrated Mirroring (IM or RAID 1) and Integrated Striping (IS or RAID 0) technology. Integrated RAID is OS independent, easy to install and configure, and does not require a special driver. A RAID Volume is seen as a single drive by the host BIOS and OS.

The LSISAS1064 controller is based on the Fusion-MPT (Message Passing Technology) architecture. The Fusion-MPT architecture requires only a thin device driver that is independent of the I/O bus. LSI Logic provides the device drivers for various operating environments.

The ILOM Service Processor monitors the GPIOs from the SAS1064 controller. If the controller indicates a failure, the service processor lights the fault LED on the corresponding disk drive and logs the error in the SP event log.

F.4.1.1 Automatic Data Resynchronization and Hotspares

Caution - Possible data loss: If you insert an drive that has been configured with a RAID volume into a server that did not previously have its drives configured with RAID volumes, the existing drive(s) in the server will be converted to RAID volumes during automatic synchronization and any existing data on the existing drive(s) in the server will be erased. Before permanently removing an drive that is part of an active RAID volume, use the LSI Configuration Utility to delete the RAID volume from the drive to avoid causing this problem.

The SCSI parameters, including RAID volumes configuration, are set up using the LSI BIOS configuration utility accessible by pressing the CTRL+C keys during the boot process. The LSI RAID firmware and BIOS is OS-independent and you set up RAID while in MPTBIOS POST, before booting to an OS.

The parameters are saved in both the NVRAM and the disk drives. The RAID firmware needs 64 MB of unused disk space at the end of each drive to store the metadata.

The metadata stored on the disk drives contains sufficient information to restore and reactivate the RAID volumes in case the NVRAM is lost (for example, when the motherboard is replaced). However, if removed, the disk drives must first be labelled to make sure that they are placed back in the same disk bays from which they were removed when reinstalled. When the system is powered on, the RAID volumes are automatically activated and resynchronization is automatically performed.

One of the disk drives can be set up as a hotspare disk if a RAID 1 (mirroring) volume is already set up. If one of the two disk drives used in the RAID 1 volume fails, the hotspare drive automatically replaces it in the volume and resync is immediately performed.

It must be noted that, until the resync is completed, the system is vulnerable to a failure of the now “primary” disk (the disk left from the original mirrored volume) since full data redundancy is not yet achieved. When the bad disk is replaced, the new disk automatically becomes the new hotspare disk for the mirrored volume.

F.4.1.2 RAID Level Support

The following items describe the RAID level support for these servers:

• RAID 1 (mirroring) is supported.
• RAID 0 (striping) is supported.
• LSI RAID 1E or IME (mirroring over more than two drives) is not supported.
• RAID 0+1 and 1+0 are not supported by the SAS1064 controller.

F.4.1.3 RAID Volume Support

The following items describe the RAID volumes supported for these servers:

• Up to two active RAID volumes are supported per system (RAID 0, RAID 1 or both).
• A striped volume (RAID 0) can contain up to four disk drives.
• A mirrored volume (RAID 1) can contain up to two disk drives.
• One disk drive can be set up as hotspare for a RAID 1 array (one hotspare disk per controller maximum).
• Volumes are transparent to the OS and are seen as a single physical disk drive no matter how many drives they contain.

F.4.1.4 RAID Combination Support

Possible RAID Combinations in a four-drives server are listed below:

• Two drives RAID 0 + two drives non-RAID
• Two drives RAID 1 + two drives non-RAID
• Two drives RAID 0 + two drives RAID 1
• Two drives RAID 0 + two drives RAID 0
• Two drives RAID 1 + Two drives RAID 1
• Three drives RAID 0 + one drive non-RAID
• Four drives RAID 0
• Two drives RAID 1 + one hotspare drive + one drive non-RAID
• Four drives non-RAID

F.4.2 Creating a RAID 0 Volume

A RAID 0 volume, also referred to as Integrated Striping (IS), offers the ability to stripe data across multiple hard disks. This can increase storage capacity and performance by combining multiple disks into one logical volume.

Follow these steps to create a RAID 0 volume on an adapter that does not currently have a volume configured.

1. In the Configuration Utility, select an adapter from the Adapter List.

2. Select the RAID Properties option.

3. When you are prompted to create either an IS volume or an IM volume, select Create IS Volume.

The next screen shows a list of disks that can be added to a volume.

4. Move the cursor to the RAID Disk column. To add a disk to the volume, change the “No” to “Yes” by pressing the + key, - key, or space bar.

As disks are added, the Array Size field changes to reflect the size of the new volume. There are several limitations when creating a RAID 0 volume:

• All disks must be SAS (with SMART support).
• Disks must have 512-byte blocks and must not have removable media.
• There must be at least two drives in a valid volume.
• No more than eight drives are allowed in a volume.
• Hot spare drives are not allowed for RAID 0 volumes.

5. When the volume has been fully configured, press C and select Save changes, then exit this menu to commit the changes.

The Configuration Utility will pause while the array is being created.

F.4.3 Creating a RAID 1 Volume

A RAID 1 volume, also referred to as Integrated Mirroring (IM), offers the ability to mirror data from one hard disk onto another one. This can increase reliability by combining multiple disks into one logical volume. Follow these steps to create a RAID 1 volume on an adapter that does not currently have a volume configured.

1. In the Configuration Utility, select an adapter from the Adapter List.

2. Select the RAID Properties option.

3. When you are prompted to create either an IS volume or an IM volume, select Create IM Volume.

The next screen shows a list of disks that can be added to a volume.

4. Move the cursor to the RAID Disk column. To add a disk to the volume, change the “No” to “Yes” by pressing the + key, - key, or space bar.

When the first disk is added, the utility will prompt you to keep existing data or overwrite existing data.

5. Press M to keep the existing data on the first disk or press D to overwrite it.

If you keep the existing data, this is called a migration. The first disk will be mirrored onto the second disk, so the data you want to keep must be on the first disk added to the volume. Data on all other disks will be lost.

As disks are added the Array Size field will change to reflect the size of the new volume. There are several limitations when creating a RAID 1 volume:

• All disks must be SAS (with SMART support).
• Disks must have 512-byte blocks and must not have removable media.
• There must be two drives in a valid volume.

6. (Optional) Add a hotspare to the volume by moving the cursor to the Hot Spare column and pressing the + key, - key, or space bar.

7. When the volume has been fully configured, press C and select Save changes, then exit this menu to commit the changes.

The Configuration Utility will pause while the array is being created.

F.4.4 Managing Hot Spares

Follow these steps to add a hotspare to a RAID 1 volume.

1. Select Manage Hot Spare.

2. Select a disk from the list by pressing the + key, - key, or space bar.

3. After you select the hotspare disk, press C.

4. Select Save changes then exit this menu to commit the changes.

The Configuration Utility will pause while the hotspare is being added.

Follow these steps to delete a hotspare from a RAID 1 volume.

1. Select Manage Hot Spare.

2. Remove the current hotspare disk from the list by pressing the + key, - key, or space bar.

3. After you clear the hotspare, press C.

4. Select Save changes then exit this menu to commit the changes.

The Configuration Utility will pause while the hotspare is being removed.

F.4.5 Creating a Second RAID Volume

The LSI Logic SAS controllers support two active RAID volumes. If one volume is already configured, follow these steps to add a second volume.

1. In the Configuration Utility, select an adapter from the Adapter List.

2. Select the RAID Properties option.

This displays the current volume.

3. Press C to create a new volume.

4. Create the new volume:

• To create a second RAID 0 volume, continue with Step 2 of Creating a RAID 0 Volume.
• To create a second RAID 1 volume, continue with Step 2 of Creating a RAID 1 Volume.

F.4.6 Viewing RAID Volume Properties

Follow these steps to view the properties of RAID volumes.

1. In the Configuration Utility, select an adapter from the Adapter List.

2. Select the RAID Properties option.

The properties of the current volume are displayed.

3. If more than one volume is configured, press Alt+N to view the next array.

4. To manage the current array, press Enter when the Manage Array item is selected.

F.4.7 Synchronizing an Array

Synchronizing an array means that the firmware synchronizes the data on the secondary disk(s) with the data on the primary disk of the mirror. Follow these steps to start a synchronization for a RAID 1 volume.

1. Select Synchronize Array.

2. Press Y to start the synchronization, or N to cancel it.

F.4.8 Activating an Array

An array can become inactive if, for example, it is removed from one controller or computer and moved to another one. The Activate Array option enables you to reactivate an inactive array that has been added to a system. This option is only available when the selected array is currently inactive.

1. Select Activate Array.

2. Press Y to proceed with the activation, or press N to abandon it.

After a pause, the array becomes active.

F.4.9 Deleting an Array

Caution - Before deleting an array, be sure to back up all data on the array that you want to keep.

Follow these steps to delete a selected array.

1. Select Delete Array.

2. Press Y to delete the array, or press N to abandon the deletion.

After a pause, the firmware deletes the array.

F.4.10 Locating a Disk Drive

There are several ways to physically locate a disk drive, as long as the firmware is correctly configured and the drives support disk location.

• During RAID creation, when a disk is set to Yes as part of a RAID volume, its locate LED is enabled. When it is set back to No or the RAID volume is created, the locate LED is cleared.
• Disks can also be located from the SAS Topology screen. To locate a disk, move the cursor to the disk and press Enter. The Locate LED on the disk remains activate until the next key is pressed.
