Getting Started 4 In this chapter... Choosing a RAID Level.......................................................................................................... 31 Selecting Disk Drives.............................................................................................................. 32 Selecting Cables ...................................................................................................................... 33 Installation Options ..............................................
Chapter 4: Getting Started ● 31 Choosing a RAID Level This section provides a brief overview of the RAID levels supported by your Adaptec RAID controller, including the minimum and maximum number of disk drives required by each. ● RAID 0 (Non-redundant Array)—Stripes data across multiple disk drives. Improved performance but no redundancy (see page 76). ● RAID 1 Array—Created from two disk drives where one disk drive is a mirror of the other (the same data is stored on each disk drive).
Chapter 4: Getting Started ● 32 Selecting Disk Drives When selecting disk drives for your RAID array, ensure that all the disk drives have the same performance level. You can use different-sized disk drives in the array, but the array will be limited to the capacity of the smallest and slowest disk drive. For more information, refer to the Adaptec Storage Manager User’s Guide for Internal RAID Storage or online Help.
Chapter 4: Getting Started ● 33 Selecting Cables This section describes the cable options and requirements for your Adaptec controller: ● For SAS cables, see this page. ● SATA cables, see page 34. ● SCSI cables, see page 35. SAS Cables You need one SAS cable for each disk drive you are connecting to your Adaptec SAS RAID controller. Depending on your requirements, you can use any of these cables: External cable (SFF-8470 to SFF-8470)—Connects to an external SAS enclosure.
Chapter 4: Getting Started ● 34 Internal mini-SAS to SATA fan-out (SFF-8087 to 4x SATA)—Connects to four SATA disk drives. External SAS (SFF-8088)—Connects to SAS or SATA disk drives on a backplane. Internal SAS (SFF-8484)—Connects to SAS or SATA disk drives on a backplane. Internal mini-SAS (SFF-8087)—Connects to SAS or SATA disk drives on a backplane. Cable connectors are keyed so that you can’t insert them incorrectly. Adaptec recommends using only Adaptec SAS cables.
Chapter 4: Getting Started ● 35 All SATA straight connector to straight connector cables have the same connectors, as shown in the following figure, and the connectors are keyed so that you can’t insert them incorrectly. Adaptec recommends using only Adaptec SATA cables. For more information or to purchase cables, visit the Adaptec Web site at www.adaptec.com. SCSI Cables Depending on your requirements, you may need one or two internal cables. You may also need one external SCSI cable.
Chapter 4: Getting Started ● 4 Install your operating system and the controller driver (see page 48.) 5 Install Adaptec Storage Manager and begin to manage your data storage (see page 61). 36 Note: Currently, Adaptec Storage Manager is not supported on FreeBSD. To create and manage arrays, use the ARC utility. See page 63 for more information. Installing on an Existing Operating System 1 Install and connect your controller and internal disk drives (see page 37).

Solving Problems 10 In this chapter... Troubleshooting Checklist ..................................................................................................... 65 Silencing the Alarm ................................................................................................................ 65 Recovering from a Disk Drive Failure ................................................................................... 65 Resetting the Controller.......................................................
Chapter 10: Solving Problems ● 65 Troubleshooting Checklist If you encounter difficulties installing or using your Adaptec RAID controller, check these items first: ● With your computer powered off, check the connections to each disk drive, power supply, LED connector, and so on. Try disconnecting and reconnecting disk drives from the Adaptec RAID controller. ● Check that your Adaptec RAID controller is installed in a compatible expansion slot (PCI, PCI-X, or PCIe).
Chapter 10: Solving Problems ● 66 Failed Disk Drive Protected by a Hot Spare When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is automatically incorporated into the array and takes over for the failed drive. To recover from the failure: 1 Remove and replace the failed disk drive (following manufacturer’s instructions).
Chapter 10: Solving Problems ● 67 Multiple Failures in the Same Array Except in RAID 6 and RAID 60 arrays (see page 75), if more than one disk drive fails at the same time in the same array, the data can’t be recovered. Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if available). Note: In some instances, RAID 10 and RAID 50 arrays may survive multiple disk drive failures, depending on which disk drives fail.
Introduction to Serial Attached SCSI A In this appendix... Terminology Used in This Chapter ....................................................................................... 69 What is SAS? ........................................................................................................................... 69 How Do SAS Devices Communicate? ................................................................................... 70 What’s a Phy? .....................................................
Appendix A: Introduction to Serial Attached SCSI ● 69 Terminology Used in This Chapter For convenience, SAS HBAs and SAS RAID controllers are referred to generically in this chapter as SAS cards. HBAs, RAID controllers, disk drives, and external disk drive enclosures are referred to as end devices and expanders are referred to as expander devices. For convenience, this chapter refers to end devices and expander devices collectively as SAS devices.
Appendix A: Introduction to Serial Attached SCSI ● 70 How Do SAS Devices Communicate? SAS devices communicate with each other through links. A link is a physical connection between two phys. As shown in the following figure, SAS devices contain ports (see page 71), ports contain phys, and each phy contains one transmitter and one receiver—one transceiver. A phy can belong to one port only.
Appendix A: Introduction to Serial Attached SCSI ● 71 What’s a SAS Port? Note: Because the physical link between SAS devices is from phy to phy, rather than port to port, a “port” is more of a virtual concept, different from what is normally considered a port on other types of RAID controllers and storage devices. A port is one or more phys. A narrow port contains one phy. A wide port typically contains four phys.
Appendix A: Introduction to Serial Attached SCSI ● 72 How are Disk Drives Identified in SAS? In the BIOS and in the management utilities (see Identifying Disk Drives on page 91), disk drives are identified in the following formats: ● CNX:DevY = Device Y is attached to Connector X (see Direct-attach Connections below for more information) ● BoxX:SlotX = Enclosure X is attached to a disk drive in Slot X (see Backplane Connections below for more information) ● ExpX:PhyX = Expander X is attached to Phy
Appendix A: Introduction to Serial Attached SCSI ● 73 Some backplanes support daisy-chain expansion to other backplanes. For example, you can daisy-chain (connect one to the next) up to nine Adaptec S50 enclosures to a single SAS card in a host system. SAS Expander Connections A SAS expander device literally expands the number of end devices that you can connect together.
Appendix A: Introduction to Serial Attached SCSI ● 74 How is SAS Different from Parallel SCSI? In summary, although SAS and parallel SCSI both use the SCSI command set, how they move data from one place to another is very different. To support point-to-point serial data transport, SAS introduces new types of connectors, cables, connection options, and terminology. Generally speaking, SAS is faster and more flexible than parallel SCSI, and provides more options for building your storage space.
Understanding RAID B In this appendix... Understanding Drive Segments............................................................................................. 76 Non-redundant Arrays (RAID 0) .......................................................................................... 76 RAID 1 Arrays ........................................................................................................................ 77 RAID 1 Enhanced Arrays...........................................................
Appendix B: Understanding RAID ● 76 Understanding Drive Segments A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk drive can include both RAID segments (segments that are part of an array) and available segments. Each segment can be part of only one logical device at a time. If a disk drive is not part of any logical device, the entire disk is an available segment.
Appendix B: Understanding RAID ● 77 RAID 1 Arrays A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays provide improved performance, with twice the read rate and an equal write rate of single disks. However, capacity is only 50 percent of independent disk drives.
Appendix B: Understanding RAID ● 78 RAID 10 Arrays A RAID 10 array is built from two or more equal-sized RAID 1 arrays. Data in a RAID 10 array is both striped and mirrored. Mirroring provides data protection, and striping improves performance. Drive segment size is limited to the size of the smallest disk drive in the array.
Appendix B: Understanding RAID ● 79 RAID 5 Arrays A RAID 5 array is built from a minimum of three disk drives, and uses data striping and parity data to provide redundancy. Parity data provides data protection, and striping improves performance. Parity data is an error-correcting redundancy that’s used to re-create data if a disk drive fails. In RAID 5 arrays, parity data (represented by Ps in the next figure) is striped evenly across the disk drives with the stored data.
Appendix B: Understanding RAID ● 80 RAID 5EE Arrays A RAID 5EE array—also known as a hot space—is similar to a RAID 5 array except that it includes a distributed spare drive and must be built from a minimum of four disk drives. Unlike a hot spare, a distributed spare is striped evenly across the disk drives with the stored data and parity data, and can’t be shared with other logical disk drives. A distributed spare improves the speed at which the array is rebuilt following a disk drive failure.
Appendix B: Understanding RAID ● 81 RAID 50 Arrays A RAID 50 array is built from six to forty-eight disk drives configured as two or more RAID 5 arrays, and stripes stored data and parity data across all disk drives in both RAID 5 arrays. (For more information, see RAID 5 Arrays on page 79.) Note: Because they support four disk drives only, the Adaptec 2420SA RAID controller can’t support RAID 50 arrays. The parity data provides data protection, and striping improves performance.
Appendix B: Understanding RAID ● 82 RAID 6 Arrays A RAID 6 array—also known as dual drive failure protection—is similar to a RAID 5 array because it uses data striping and parity data to provide redundancy. However, RAID 6 arrays include two independent sets of parity data instead of one. Both sets of parity data are striped separately across all disk drives in the array. RAID 6 arrays provide extra protection for your data because they can recover from two simultaneous disk drive failures.
Appendix B: Understanding RAID ● 83 Selecting the Best RAID Level Use this table to select the RAID levels that are most appropriate for the logical drives on your storage space, based on the number of available disk drives and your requirements for performance and reliability.

Note: Also available—ACU for DOS. See page 93. ● A -Select Utility—SerialSelect, SATASelect, or SCSISelect, for modifying your controller and disk drive settings (see page 87).
Appendix C: Using the Adaptec RAID Configuration Utility ● 86 Managing Existing Arrays To view or modify existing arrays, select Manage Arrays from the main ACU menu. From the Manage Arrays menu, you can: ● View the properties of an array. Note: Failed drives are displayed in a different text color. ● Make an array bootable (see Creating Bootable Arrays on page 86). ● Assign or remove hot spares. ● Delete an array.
Appendix C: Using the Adaptec RAID Configuration Utility ● 87 Secure Erasing Disk Drives When you perform a secure erase on a disk drive, all data on that disk drive is completely and irretrievably eradicated. Secure erase performs three distinct writing passes to the disk drive being erased—it does not just write zeros. Performing a secure erase takes up to six times longer than clearing (or zeroing) a disk drive.
Appendix C: Using the Adaptec RAID Configuration Utility ● 88 Modifying Your Controller’s Configuration Note: Default controller settings are suitable for most computers. Adaptec recommends that you do not change the default setting. To modify your controller’s settings, select Controller Configuration from the main -Select utility menu. The following table lists controller configuration options. Some options may not be available for your controller.
Appendix C: Using the Adaptec RAID Configuration Utility ● 89 SAS-specific Controller Settings In addition to the general settings listed on page 88, your Adaptec SAS controller has SASspecific settings that can be modified if required. (For more information about SAS, see page 68.) Note: This feature is not available with the Adaptec 31205 or Adaptec 31605 controllers. To modify SAS-specific settings, select PHY Configuration from the SerialSelect main menu.
Appendix C: Using the Adaptec RAID Configuration Utility ● 90 SCSI-specific Controller Settings In addition to the general settings listed on page 88, your Adaptec SCSI controller has SCSIspecific settings that can be modified if required. To modify SCSI-specific settings, select SCSI Configuration from the SCSISelect main menu. SCSI Device Settings You can use SCSISelect to modify some of the settings on the SCSI devices connected to your SCSI controller.
Appendix C: Using the Adaptec RAID Configuration Utility ● 91 Formatting and Verifying Disk Drives You can use the disk utilities to low-level format or verify your disk drives. (New disk drives are low-level formatted at the factory and do not need to be low-level formatted again.) ! Caution: Before you format a disk drive, back up all data. Formatting destroys all data on a disk drive. To format or verify a disk drive: 1 Start the ARC utility (see page 85).
Appendix C: Using the Adaptec RAID Configuration Utility ● 92 The location information of a disk drive is determined by three types of connections: ● Direct attached drives—The connection is determined by the cable connected to a device, for example CN1 (connector 1) is connected to DEV1 (device 1). For more information, see Direct-attach Connections on page 72. ● Storage Enclosure Processor (SEP) managed devices—The connection is determined by an active backplane.
Using the Array Configuration Utility for DOS D In this appendix... Getting Started ....................................................................................................................... 94 Working in the ACU Using Menus........................................................................................ 94 Running the ACU Using Scripts............................................................................................
Appendix D: Using the Array Configuration Utility for DOS ● 94 Getting Started Note: You need a bootable floppy disk to complete this task. The ACU for DOS runs from a floppy disk which you can create using the RAID Installation CD that came in your Adaptec RAID controller kit. To create the ACU floppy disk: 1 Insert your RAID Installation CD into the CD drive, then browse to this file: packages/firmware/controllermodel/acu.exe Where controllermodel is the model number of your Adaptec RAID controller.
Appendix D: Using the Array Configuration Utility for DOS ● 95 Running the ACU Using Scripts To work in the ACU using scripts: 1 Insert the ACU floppy disk (see page 94), then start or restart your computer. The computer boots to the DOS command line. 2 Type ACU on the command line, specify a script file, and specify either the /P or /R switches listed in the following table. (Don’t specify both.) You may also add one or both of the optional switches. Note: Command line syntax is not case sensitive.
Appendix D: Using the Array Configuration Utility for DOS ● 96 About Record Mode Note: You can also create a script file manually (see the following section). In Record Mode, the ACU writes a RAID controller’s existing array configuration to a specified script file, which lets you create the same configuration by running the ACU in Playback Mode (/P switch) with the resulting script. You can only record one RAID controller at a time with Record Mode.
Appendix D: Using the Array Configuration Utility for DOS ● 97 Array Definition Block Keywords The array definition block always begins with the keyword Array and ends with the keyword End. The other required array definition keywords are Drives and Type. Array definition keywords and descriptions are listed in this table. Keyword Required? Description Array Yes Indicates the start of an array definition block. No default. See page 97.
Appendix D: Using the Array Configuration Utility for DOS ● 98 End Keyword End is a required keyword, indicating the end of the block. HotspareDrives Keyword Hotspare Drives is an optional keyword, specifying the hot spares to assign to the array. The syntax for listing hot spares is the same as the Drives Keyword on page 97. If Hotspare Drives is not specified, no hot spares are assigned to the array.
Appendix D: Using the Array Configuration Utility for DOS ● 99 Method Keyword Method is an optional keyword, indicating which method to use when creating a redundant (RAID 1, 1E, 10, 5, 5EE, 50, 6 and 60) array. Possible values: ● Build (the default)—Perform a Build/Verify process on the array. Takes longer than Clear, but allows you to begin using the array immediately. ● Clear—Clear the array.
Appendix D: Using the Array Configuration Utility for DOS ● 100 Type Keyword Type is a required keyword, indicating the array type. There is no default value. The possible values: Volume, RAID0, RAID1, RAID5, RAID10, or RAID50. Depending on the RAID levels supported by your RAID controller, additional possible values are: RAID1E, RAID5EE, RAID6, RAID60.
Appendix D: Using the Array Configuration Utility for DOS ● 101 ControllerID Keyword ControllerID is an optional keyword to change the SCSI ID of the controller. Normally, the SCSI controller is assigned SCSI ID 7 on each of its channels. You can specify any ID value between 0 and 7. ! Caution: Do not change the SCSI ID of the controller unless directed to do so by Adaptec Technical Support. For example: ControllerID=7 End Keyword End is a required keyword, indicating the end of the block.
Appendix D: Using the Array Configuration Utility for DOS ● 102 Code Description 19 Unable to read SATA port parameters. Unable to read SCSI channel parameters. 20 Unable to write SATA port parameters. Unable to write SCSI channel parameters. 21 Failed in getting kernel version. Unknown product ID. 22 Kernel timeout in writing command. 23 No RAID channels available 24 Error: wrong stripe size in creating array - script mode.
Appendix D: Using the Array Configuration Utility for DOS ● 103 # Clear the array (don’t build/verify it) Method=Clear # Don’t wait for clear to complete Wait=No # Use drives 0, 1, 2 Drives=0:0:0, 0:1:0, 0:2:0 End Sample Script for SATA Controllers This is a sample ACU file that will initialize all disk drives connected to the SATA controller and create a RAID 5 array with the disk drives on ports 0, 1, and 2.

System Requirements ........................................................................................................... 105 Before You Begin .................................................................................................................. 105 Running the Menu-based AFU............................................................................................ 106 Running the AFU from the Command Line...........................
Appendix E: Using the Adaptec Flash Utility ● 105 System Requirements ● MS–DOS version 5.0 or later. Note: You can’t run the AFU from a DOS command prompt window under any version of Windows. ● At least 8 MB of extended memory. Compatibility Notes ● Supports HIMEM.SYS; compatible with other DOS drivers running under HIMEM.SYS (for example, SMARTDRV.SYS and SETVER.SYS). ● Does not support DOS extenders installed in memory, such as EMM386.SYS and DOS4GW.
Appendix E: Using the Adaptec Flash Utility ● 106 Creating the Firmware Floppy Disks Note: You will need at least two bootable MS-DOS floppy disks to complete this task. You can’t create a bootable floppy disk using Windows 2000. To create the firmware floppy disks: 1 Create a bootable MS–DOS floppy disk and copy these files to it: ● AFU.exe ● Axxxx01.ufi where xxx is the model number of your controller. Note: Most controller model numbers have a suffix (for example Adaptec 4800SAS).
Appendix E: Using the Adaptec Flash Utility 6 ● 107 Complete the flash operation and restart your computer before trying to use the RAID controller again. (You can not use your RAID controller while you are updating its flash.) Running the AFU from the Command Line Note: You can also run a menu-based AFU (see page 106). To run the AFU from the command line: 1 Power off your computer, insert the first AFU floppy disk, then power on your computer.
Appendix E: Using the Adaptec Flash Utility ● 108 These switches are available: ● /C —One or more RAID controller IDs representing the set of RAID controllers on which to perform the specified command. The default is 0; if the computer has multiple RAID controllers, the AFU defaults to controller 0 unless you specify otherwise.
Appendix E: Using the Adaptec Flash Utility ● 109 Verify Compares the contents of each of the flash components on a RAID controller to the corresponding image in a UFI file, and indicates whether they match. After using the VERIFY command, you must restart the computer. The command syntax for the VERIFY command is as follows: AFU VERIFY [/C] [/D ] This example shows a typical system response after a VERIFY command. A:\> AFU VERIFY /C 0 Adaptec Flash Utility V4.
Appendix E: Using the Adaptec Flash Utility ● 110 Updating the Flash Using the AFU Command Line 1 Create the firmware floppy disks (see page 106). 2 Power off your computer, insert the first AFU floppy disk, then power on your computer. If your computer isn’t set up to boot from the bootable floppy disk, enter the system setup utility to change the setting.
