The forced parameter represses any warning message prompts. If you specify a drive range, any drives in the range that do not meet the previous criteria are not used. Example commands: =>...
Page 69 If you add an odd number of drives to an array that contains a RAID 1+0 logical drive, you are prompted to convert the RAID 1+0 logical drive to RAID 5 or RAID 6 (ADG). Adding the forced parameter to the command prevents this prompt from appearing.
Page 70 Moving an array automatically removes any previously assigned spare drives. If spares are assigned to the existing array, they must be designated for the array when it is moved. Syntax: <target> modify drives=[#:]#:#-[#:]#:# spares=[#:]#:#-[#:]#:# where <target> is an array, and the specified physical drives are the new destination for the array. For example, in an existing array, three 72-GB SAS drives (1e:1:4-1e:1:6) are the source.
Page 71 IMPORTANT: An array expansion, logical drive extension, or logical drive migration takes about 15 minutes per gigabyte. While this process is occurring, no other expansion, extension, or migration can occur simultaneously on the same controller. Controllers that do not support a battery-backed write cache do not support this process.
Page 72 Setting the preferred path mode The preferred path mode determines how I/O traffic to the logical drives is managed on controllers that are in an active/active configuration. • In Automatic mode, the storage system automatically selects a suitable path for I/O traffic to each logical drive depending on the host I/O patterns at the time.
Page 73 • At the medium setting, rebuilding occurs for half of the time, and normal system operations occur for the rest of the time. • At the high setting, the rebuild takes precedence over all other system operations. If the logical drive is part of an array that has an online spare, rebuilding begins automatically when drive failure occurs.
Page 74 <target> modify ssd=# where <target> is a controller and # is a number between 1 and 30. This number determines the delay time in seconds, but you do not need to include units with the command. Example command: => ctrl sn=P56350D9IP903J modify ssd=3 Re-enabling a failed logical drive If a logical drive has failed and the data on it is invalid or non-recoverable, you can re-enable the logical drive so that it can be reused.
Page 75: Using Acu Scripting
NOTE: Disabling the array accelerator for a logical drive reserves use of the accelerator cache for other logical drives on the array. This feature is useful if you want the other logical drives to have the maximum possible performance (for example, if the logical drives contain database information).
Page 76: Using An Input Script
The -e switch information is used only if ACU must generate an error file. By default, ACU names the error file ERROR.ini and places it in the ACU working directory.

Page 82 RaidArrayId This option specifies the RaidArrayId for controllers that support this feature, such as fibre and shared storage controllers. The RaidArrayId is a user-defined string that identifies controllers. "XXXXXXXXXXXXXXXXXXXX" The value can be a string of varying length that consists of any of the following characters: a-z A-Z 0-9 ! @ # * ( ) , - _ + : .
Page 83 Video performance options Video performance options require SAAP ("About SAAP" on page 8). To optimize the controller performance for video, set values for the following options as indicated: DPOEnable = No ElevatorSortEnable = Yes IRPEnable = No In addition: • Set the MNPDelay to any integer value from 1 to 60 (units are minutes).
Page 84 • If the value of the ClearConfigurationWithDataLoss (on page 81) 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.

ShrinkSize In Reconfigure mode, this option specifies the resulting size of the logical drive (in MB) to be reduced. ShrinkSize is not valid in Configure mode.
Page 89 You can enter a numerical value for this option to specify the size of the data strips (in kilobytes), or you can leave this option blank and allow ACU to use a default value. Strip sizes available for a RAID level vary based on the controller and the controller firmware level. The maximum strip size changes dynamically and is reduced for arrays with a large number of data drives or with smaller controller cache sizes.

Page 109: Drive Arrays And Fault-Tolerance Methods
Drive 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 110 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 111: Effects Of A Drive Failure
The 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 112: Fault-Tolerance Methods
• RAID 50 configurations can tolerate one failed drive in each parity group. • RAID 6 configurations can tolerate two failed drives at a given time. • RAID 60 configurations can tolerate two failed drives in each parity group. • RAID 1 (ADM) and RAID 10 (ADM) configurations can tolerate multiple drive failures if no more than two drives, mirrored to one another, fail.
Page 113: 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 114: 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 115 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 116: Raid 5-Distributed Data Guarding
RAID 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 117 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 118: Raid 50
RAID 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 119: Raid 60
RAID 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 121 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.
