B DOS Utilities In this Appendix... Using the Adaptec Flash Utility (AFU) Using the Array Configuration Utility (ACU) B-1 B-11 Using the Adaptec Flash Utility (AFU) The Adaptec® Flash Utility (AFU) is a DOS application used to update the flash EEPROM components on one or more Adaptec SCSI RAID controllers. The utility can also be used to verify a controller’s current flash contents against the flash images in a specified file or to save a controller’s current flash contents to a file.
DOS Utilities The process of updating a controller’s flash must be done carefully to avoid rendering the controller inoperable. AFU is designed to be easy to use with all the necessary safeguards to prevent a user from accidentally damaging the controller’s flash contents. Overview of the AFU The AFU performs the following primary functions: ■ Update—Updates all the flash components on a controller with the flash image data from a UFI file.
DOS Utilities ■ The AFU can run from a partition on a drive or array attached to the controller you are updating. Once the flash update begins, no I/O is possible to any array attached to that controller until the flash operation is completed and the system is restarted. ■ If you want to update multiple controllers in the same system, you should first update the boot controller’s flash, restart the system, and then update the flash for any remaining controllers.
DOS Utilities Running the AFU You can run the AFU from its graphical user interface (GUI) or from the command line. Accessing the AFU from the GUI To access the AFU: 1 At the DOS command prompt (typically A:\>), type AFU with no arguments. The main menu to the AFU is displayed. 2 Select Select Controllers and select the controllers to be flashed. 3 Select Select an Operation. 4 Select any available AFU function and follow the on-screen instructions.
DOS Utilities The AFU switches are as follows ■ /C is one or more controller IDs representing the set of controllers on which to perform the specified command. You can specify a single controller ID, for example: /C 0 multiple IDs separated by commas, for example: /C 0,2 or ALL to indicate all controllers. This switch is required. If no /C switch is specified, the system returns a fatal error message. See each individual command for the default switch values.
DOS Utilities 5 At the DOS prompt, type afu list and press Enter. This command displays a list of the controllers in your system. Take note of the controllers you would like to update and its number (or numbers if there are more than one). Verify that the controller you wish to update is identified.
DOS Utilities 9 If there are additional UFI files this process is repeated until the complete image has been read, the controller flash is updated with the new image. AFU Commands The following pages describe each of the AFU commands in detail. For ease of use, the commands are presented in alphabetical order. HELP The HELP command displays a summary of AFU functions and command switches.
DOS Utilities SAVE The SAVE command saves the contents of a controller’s flash in a UFI file. The name of the UFI file is based on the controller type and cannot be changed. Use the /D switch to specify the drive and directory where you want AFU to create the UFI file. Note: You can specify only one controller ID. If you include the /C switch and specify more than one controller, the AFU displays an error message and exits. You must restart the computer following a SAVE command.
DOS Utilities Example A:\> AFU UPDATE /C 0 Adaptec Flash Utility V4.0-0 B5749 (c)Adaptec Inc. 1999–2002. All Rights Reserved. Updating Controller 0 (Adaptec 2810) Reading flash image file (Build 5749) AFU is about to update firmware on controllers Adaptec 2810 ***PLEASE DO NOT REBOOT THE SYSTEM DURING THE UPDATE*** This might take a few minutes. Writing Adaptec 2810 (4MB) Flash Image to controller 0...OK. Verifying...OK Please restart the computer to allow firmware changes to take effect.
DOS Utilities After using the VERSION command, you must restart the computer upon completion of this command. Default Switch Values If you do not include the /C switch, the AFU returns a fatal error message. Examples The following example displays version information about all supported controllers. A:\> AFU VERSION /C 0 Adaptec Flash Utility V4.0-0 B5749 (c)Adaptec Inc. 1999–2002. All Rights Reserved.

DOS Utilities The table below lists the required and optional ACU command-line switches. Switch Description /P Playback Mode Switch—In this mode, the ACU reads the contents of the specified script file and creates arrays and configures channel settings based on the properties defined in the script. The is the name of the script file. It can include a drive, directory, and filename and extension, but only the filename is required. If no drive or directory is specified, defaults are used.
DOS Utilities Playback Mode Playback mode enables you to create one or more arrays based on the properties defined in a script file. It also enables you to configure certain properties for each channel on the controller. When you create an array, you can specify any of the array properties listed in the table below. Property Type Description Supported array types are: Volume ■ RAID 0 ■ RAID 1 ■ RAID 5 ■ RAID 10 ■ Size Size of the array to be created.
DOS Utilities In addition, there are other array properties that enable you to control the various array settings during creation. See Array Definition Block Properties on page B-25 for the complete list of array properties. Note: You can configure each individual channel on the controller using this property, which specifies the device ID number of the controller on the channel.
DOS Utilities Because the ACU reads the entire script file before creating any arrays, the position of the InitializeAll=Yes property within the script is not significant. Continuing the previous example, if InitializeAll=Yes is specified in the second RAID 5’s definition, the ACU initializes all drives before creating the first RAID 0. Note: If a build/verify is in progress when an array is deleted, it is automatically terminated.
DOS Utilities The ACU provides a way to do this. When you use record mode to record a controller’s configuration and you specify a log file (/L switch), the ACU writes build/verify and clear status information about each array in the configuration to the log file. An application or batch file can then parse the resulting log file to determine whether an array’s build/verify or clear is complete, in progress (a percentage of the task completed), or failed.
DOS Utilities Build/Verify Operations on RAID 10 Arrays For a RAID 10 array, the status message indicates the percent of the build/verify completed for the parent and child tasks. The status updates to OK when the tasks are complete. A sample RAID 10 build status is as follows: Array #1 Status : BUILD/VERIFY = 30% Script File Syntax An ACU script file consists of one of the following: ■ Array definition block—Specifies the properties of an array, such as type, size, and cache settings.
DOS Utilities Array Definition Block Properties The table below lists the properties that can be specified within an array definition block. The table lists each property’s keyword, whether it is required, and its default value (if any). Note that the keywords are arranged so the required keywords are listed first. Required ? Default Value Array Yes None Indicates the start of an array definition block. See page B-26 for details. Drives Yes None Specifies the devices used in creating the array.
DOS Utilities Required ? Default Value Wait No Yes Indicates whether the ACU should wait for the new array’s build/verify or clear to complete before continuing. See page B-31 for details. WaitForBuild No Yes Provided for backward compatibility only. See page B-31 for details. WriteCache No Yes Indicates whether write caching is enabled for this array. See page B-31 for details. Keyword Description The following sections describe each of these keywords in detail.
DOS Utilities Type Keyword Type is a required keyword, indicating the array type. There is no default value. Note: For information about the maximum number of drives supported and minimum number of drives required, see page B-14. The Type keyword values are: ■ Volume ■ RAID0 ■ RAID1 ■ RAID5 ■ RAID10 Examples Type=Volume Type=RAID1 End Keyword End is a required keyword, indicating the end of an array definition block.
DOS Utilities Notes ■ When assigning spare drives to a RAID 10 array, the ACU assigns all the drives in the list to all the arrays within the multilevel array. ■ ACU only creates dedicated hot spares. If the same drive is assigned to protect multiple arrays, only the last array that drive is assigned to is protected. ■ The ACU makes no checks to ensure that the amount of available space on the specified spare drives is sufficient to serve as failover for the given array.
DOS Utilities Examples InitializeAll=Yes InitializeAll=No Method Keyword Method is an optional keyword, indicating which method to use when creating a RAID 5 array. Possible values are: ■ Build (the default)—Build/verify the array. ■ Clear—Clear the array. ■ Quick Init - Make the array available immediately Overall, the Build method takes longer than Clear, but it enables you to begin using the array immediately. Although faster, Clear must complete before you can begin using the array.
DOS Utilities Size Keyword The Size keyword specifies the size of the array. Specify the size as an integer or a decimal number, followed by the unit keyword MB (megabytes), GB (gigabytes), or TB (terabytes). A unit keyword is required with a numeric size value. If no unit keyword is specified, the ACU exits with an error. Specify Maximum (the default) to create an array using the maximum available space, based on the array type and drives selected. Examples Size=2.
DOS Utilities Wait Keyword The Wait keyword indicates whether the ACU should wait for the new array’s build/verify or clear to complete before continuing. The Wait property is optional; if not specified, the ACU waits for the array’s build/verify or clear to complete before continuing. Specify Wait=No to allow the ACU to continue while the build/ verify or clear completes in the background.
DOS Utilities Error Handling Because the ACU scripting feature is designed to run without user interaction, the ACU handles errors during record and playback by simply exiting immediately whenever an error is detected. Whenever the ACU encounters an error during record or playback—for example, an unrecognized keyword in a script file— it reports the error and exits. If a log file is opened, the ACU writes the error message to the log file. Otherwise, it displays the message on the screen.
DOS Utilities Code Description 9 Specified array size too big—You specified an array size that is larger than the maximum size allowed for this array. 10 Number of drives do not match the array type—The number of drives you selected is invalid for the type of array specified. 11 Unable to initialize drive—The ACU was unable to initialize one or more devices. 12 Error occurred while creating array—The ACU encountered an error creating an array.
DOS Utilities Playback and Record Notes When using ACU in playback or record mode, note the following: ■ When recording an array, the ACU does not create a Wait keyword within an array’s definition block in a script file. When playing back any script file generated from the ACU record option, the ACU uses the default setting Wait=Yes when creating an array unless you first edit the script file and include a Wait=No line in the array’s definition block.
DOS Utilities The following sample script file is a sample RAID.ACU script as referred to in the previous ACU command. This script creates the following arrays—a 500 MB, single-disk volume and a 2-GB, twodrive RAID 1 with a hotspare.

Command Line Interface (CLI) CLI commands enable you to automate testing or array creation in a production environment using Windows command scripts and Linux shell scripts. This appendix describes briefly some of the commands available in the CLI. For a full description of all the CLI commands, refer to the CLI Software Reference Guide.
Command Line Interface (CLI) Accessing the CLI in Windows To access the CLI: Note: The following procedure assumes that you accepted the default location for the software during installation. 1 Click the Start button. 2 Click Programs. 3 Browse to SMBE. The Adaptec program group displays. 4 Click CLI. Note: In Windows, when the CLI executes an background command, it displays status information in the title bar of a DOS command prompt window.
Command Line Interface (CLI) Displaying Information about Your Disks Before creating any array, use the disk show space command to display information about your disks. Note: Before you can create arrays, you need to initialize the member drives. In the following example, the Usage column indicates Free for each disk, which means that the space on each disk consists of available space. AAC0> disk show space Executing: disk show space Scsi C:ID:L Usage Size ----------- ---------- ------------0:01:0 Free 64.
Command Line Interface (CLI) Creating a RAID 0 When creating a RAID 0, you need to determine the stripe size that is most suitable for your environment. The stripe size attribute indicates the number of bytes in a stripe, the amount of data written to a segment before the I/O data stream switches to the next segment in the array. The stripe size can be 16, 32, or 64 KB. The default stripe size is 64 KB. Note that you can use the container reconfigure command at a later time to change the stripe size.
Command Line Interface (CLI) The stripe size can be 16, 32, or 64 KB. The default stripe size is 64 KB. Note that you can use the container reconfigure command at a later time to change the stripe size. To create a RAID 5, use the container create raid5 command. In the following example, a RAID 5 is created on devices 0:01:0, 0:02:0, and 0:03:0 using 100 MB of available space from each device.
Command Line Interface (CLI) Alternatively, you can use the automatic failover commands that enable you to remove a failed drive and add a hot spare in its place. The controller automatically assigns the new hot spare to replace the failed drive without your having to first assign it using the container set failover or container set global_failover commands. Note: Automatic failover works only with disks that reside in an SAF-TE- or SES-enabled enclosure.
Command Line Interface (CLI) Displaying Controller Information Controllers exhibit a number of attributes that you can display or manage using the following CLI commands: ■ controller list Controller Attribute Indicates... controller (adapter) name Name controller (adapter) type Product name controller availability Access mode Example of controller list: CLI> controller list Executing: controller list Adapter Name Adapter Type ----------------------\\.
Command Line Interface (CLI) Example of controller details: AAC0> controller details Executing: controller details Controller Information ---------------------Remote Computer: . Device Name: AAC0 Controller Type: Adaptec xxxxxx Access Mode: READ-WRITE Controller Serial Number: Last Six Digits = 8A277A Number of Buses: 2 Devices per Bus: 15 Controller CPU: i960 Controller CPU Speed: 100 Mhz Controller Memory: 64 Mbytes Battery State: Not Present Component Revisions ---------------------CLI: 3.

Each line ends with a line feed inserted by pressing Enter. The following CLI command script: 1 Opens controller AAC0 by invoking the CLI command open. 2 Invokes controller details.
D Supported RAID Types RAID is an acronym for Redundant Array of Independent Disks. The goal of RAID is to provide better performance and reliability from combinations of disk drives than possible with the same total storage space without RAID. When creating RAIDs, select drives of equal capacity and performance. Otherwise, the RAID tends to be limited in capacity and performance to that of the smallest and slowest drive.
Supported RAID Types RAID 0 A RAID 0 is created by striping data across two or more disk drives. This striping scheme creates no redundancy to protect the data. However, because the drives share load equally, RAID 0 provides the best read and write performance of any RAID type. An example of a RAID 0 array is shown below.
Supported RAID Types RAID 5 This RAID type requires at least three drives. Like RAID 0, data is striped across the drives. However, in RAID 5, parity is stored separately from data, and occupies the equivalent of one drive. The controller generates parity every time data is written to the array, and it is distributed in stripes across all the drives. In the event of a drive failure, the contents of the failed drive can be rebuilt from the data and parity on the remaining drives.
Supported RAID Types RAID 10 This dual-level RAID type is created by using two or more equalsized RAID 1 arrays to create a RAID 0. Both read and write performance are improved due to array striping. However, the performance improvement costs additional storage space due to the mirroring of the arrays.
E Specifications DC Power Requirements Voltage 5 V ± 10% Ripple and noise 50 mV peak-to-peak maximum Current Requirements Adaptec 2810SA 1 A maximum Environmental Specifications Ambient temperature 0 °C to 50 ° C Relative humidity 10% to 90%, noncondensing Altitude up to 3,000 meters Note: Forced airflow is recommended, but not required.
