Page 60: Managing Spare DrivesRapid Parity Initialization is available only for supported controllers and in arrays composed of supported physical drives. Example: of creating a logical drive with Rapid Parity Initialization: => ctrl slot=3 create type=ld drives=1e:1:1-1e:1:4 parityinitializationmethod=rapid Assigning a chassis name to the controller If a controller is configured with at least one logical drive, you can give the controller a simplified name (the chassis name) to make it easier to identify and enter the correct controller in a command.
Page 61: Expanding An Array• When a data drive fails; this mode is the default. In normal operations, and for older controllers, the firmware starts rebuilding a spare drive only when a data drive fails. With the predictive failure activation mode, rebuilding can begin before the drive fails, reducing the likelihood of data loss that could occur if an additional drive fails.
- Page 62 Shrinking an array Some controllers may not support this option or may require a license key to enable this feature. You can shrink the size of an array by removing a drive from an existing array. Observe the following criteria: •..
- Page 63 drives by specifying the new destination drives in the command (1e:1:12-1e:1:14). To maintain the same spare drive, be sure to designate the spare drive for the moved array. Example commands: => array a modify drives=1e:1:12-1e:1:14 spares=1e:1:9 => array b modify drives=1c:1:6-1c:1:7 Replacing an array Some controllers may not support this option or may require a license key to enable this feature.
- Page 64 If the operating system does not support logical drive extension, carrying out this command makes data on the logical drive unavailable. Therefore, the CLI displays a warning prompt as a safeguard in case you are using such an operating system. To prevent the prompt from appearing, use the forced parameter. Example commands: =>..
- Page 65 <target> modify [preferredpathmode=automatic manual ?] where <target> is a redundant controller. Example command: controller ch='lab 3' modify ppm=manual Assigning a redundant controller to a logical drive When you have set the preferred path mode ('Setting the preferred path mode' on page 64) in a redundant system to Manual, you must use the chassisslot command to assign each logical drive in the system to one of the redundant controllers.
- Page 66 => ctrl slot=3 modify rp=high Changing the Expand Priority setting The Expand Priority setting determines the urgency with which the controller treats an internal command to expand an array. • At the low setting level, normal system operations take priority over an array expansion. •..
- Page 67 Syntax: <target> modify reenable [forced] Example command: => ctrl slot=3 ld 1 modify reenable forced Changing the controller cache ratio The controller cache ratio setting determines the amount of memory allocated to read and write operations. Different types of applications have different optimum settings. You can change the ratio only if the controller has a battery-backed cache (because only battery-backed cache can be used for write cache) and if there are logical drives configured on the controller.
Page 68: Using Acu ScriptingEnabling a script to exit on error When a script encounters an error during execution, the exitonerror keyword enables the script to decide whether to continue or to exit the application and return an exit code. Syntax: set [exitonerror=enable disable] Example commands: set exitonerror=enable set eoe=disable..
Page 69: Creating An Acu Script FileFILENAME is the name of the ACU input file, and ext is the file extension. If you do not specify the name and location of this file, ACU searches for ACUINPUT.ini in the ACU working directory. The -internal and -external switches limit configuration operations to internal or external controllers. The -reset flag destroys any existing data and overwrites the current configuration with the configuration specified in the script.

- Page 74 You can use this option to prevent stale cache issues. ClearConfigurationWithDataLoss Clearing the configuration causes data loss because it deletes all logical volumes and arrays on the controller. If you clear a configuration, you can write commands later in the script file to create a new configuration from the liberated drive capacity.
Page 75: Video Performance OptionsThe quotes enclosing the string are optional. The quotes allow you to use leading space characters in the RaidArrayId. ReadCache, WriteCache Enter a number between 0 and 100 to specify the percentage of cache that is to be allocated to drive reads or writes.
Page 76: Array Category• Set the QueueDepth to one of the following values: 2 4 8 16 32 Automatic Array category The Array category has the following options: • Array (on page 76) • CachingArray (on page 76) • Drive (on page 76) • DriveType (on page 77) •..
- Page 77 • If the value of the ClearConfigurationWithDataLoss (on page 74) option is Yes, you can use the Drive option to remove drives from an array. Determine which mode to use: • Auto method mode—ACU configures all the available drives on the controller into one array. If the drives are of different capacities, ACU determines the capacity of the smallest drive and uses the same amount of space on all other available drives.
Page 78: Logical Drive CategoryFor controllers that support Auto Replace Drive, setting this value to AutoReplace enables a rebuilt spare drive to become a data drive in the array. When the failed data drive is replaced, it assumes the role of the former spare, eliminating the need for a second array rebuild. Behavior Description Default value for spares..

- Page 80 The maximum number of parity groups possible for a particular number of physical drives is the total number of drives divided by the minimum number of drives necessary for that RAID level (three for RAID 50, four for RAID 60). PreferredPath If you select the Manual setting for PreferredPathMode (on page 74), use the PreferredPath command to specify the path for I/O to the logical drive on a redundant controller in active/active mode.
- Page 81 Typically used after a Join command, this option ensures the proper logical volume numbering is set, for example, the boot volume is ID 1. Do not mix Renumber and Join operations in the same script, because ACU Scripting does not update its internal state after a renumber.
- Page 82 In Reconfigure mode, the default setting is the existing size of the logical drive. If you enter a larger value, ACU extends the logical drive to the new size if there is unused drive capacity on the same array, as long as the operating system supports logical drive extension.
Page 83: Hba Category• 512—512 KB • 1024—1024 KB (supported starting with Gen8 controllers) The default strip size value depends on the action mode: • In Configure action mode, the default value is determined by the RAID level that you specified earlier in the script.

Page 102: Drive Arrays And Fault-tolerance MethodsDrive arrays and fault-tolerance methods Drive arrays The capacity and performance of a single physical (hard) drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when drives fail. Connecting extra physical drives (Pn in the figure) to a system increases the total storage capacity but has no effect on the efficiency of read/write (R/W) operations.
- Page 103 With an array controller installed in the system, the capacity of several physical drives can be combined into one or more virtual units called logical drives (also called logical volumes and denoted by Ln in the figures in this section). Then, the read/write heads of all the constituent physical drives are active simultaneously, reducing the total time required for data transfer.
Page 104: Effects Of A Hard Drive Failure On Logical DrivesThe group of physical drives containing the logical drive is called a drive array, or just array (denoted by An in the figure). Because all the physical drives in an array are commonly configured into just one logical drive, the term array is often used as a synonym for logical drive. However, an array can contain several logical drives, each of a different size.
Page 105: Fault-tolerance Methods• RAID 50 configurations tolerate one failed drive in each parity group. • RAID 6 configurations tolerate two failed drives at a given time. • RAID 60 configurations tolerate two failed drives in each parity group. • RAID 1 (ADM) and RAID 10 (ADM) configurations tolerate multiple drive failures if no more than two drives, mirrored to one another, fail.
Page 106: Raid 1 And Raid 1+0 (raid 10)RAID 1 and RAID 1+0 (RAID 10) In RAID 1 and RAID 1+0 (RAID 10) configurations, data is duplicated to a second drive. When the array contains only two physical drives, the fault-tolerance method is known as RAID 1. When the array has more than two physical drives, drives are mirrored in pairs, and the fault-tolerance method is known as RAID 1+0 or RAID 10.
Page 107: Raid 1 (adm) And Raid 10 (adm)Advantages: • This method has the second highest read performance of any fault-tolerant configuration. • No data is lost when a drive fails, as long as no failed drive is mirrored to another failed drive. • Up to half of the physical drives in the array can fail. Disadvantages: •..
- Page 108 When the array has more than three physical drives, drives are mirrored in trios, and the fault-tolerance method is known as RAID 10 (ADM). In each mirrored trio, the physical drives that are not busy answering other requests answer any read requests that are sent to the array.
Page 109: Raid 5-distributed Data GuardingRAID 5—distributed data guarding In a RAID 5 configuration, data protection is provided by parity data (denoted by Px,y in the figure). This parity data is calculated stripe by stripe from the user data that is written to all other blocks within that stripe. The blocks of parity data are distributed evenly over every physical drive within the logical drive.
- Page 110 RAID 6 (ADG), like RAID 5, generates and stores parity information to protect against data loss caused by drive failure. With RAID 6 (ADG), however, two different sets of parity data are used (denoted by Px,y and Qx,y in the figure), allowing data to still be preserved if two drives fail. Each set of parity data uses a capacity equivalent to that of one of the constituent drives.
Page 111: Raid 50RAID 50 RAID 50 is a nested RAID method in which the constituent hard drives are organized into several identical RAID 5 logical drive sets (parity groups). The smallest possible RAID 50 configuration has six drives organized into two parity groups of three drives each. For any given number of hard drives, data loss is least likely to occur when the drives are arranged into the configuration that has the largest possible number of parity groups.
Page 112: Raid 60RAID 60 RAID 60 is a nested RAID method in which the constituent hard drives are organized into several identical RAID 6 logical drive sets (parity groups). The smallest possible RAID 60 configuration has eight drives organized into two parity groups of four drives each. For any given number of hard drives, data loss is least likely to occur when the drives are arranged into the configuration that has the largest possible number of parity groups.

- Page 114 Neither of these alternative fault-tolerance methods supports online spares or automatic data recovery, nor do they support auto-reliability monitoring or interim data recovery. If you decide to use one of these alternative methods, configure your arrays with RAID 0 for maximum storage capacity and refer to your operating system documentation for further implementation details.
