    The queuedepth parameter can also have a numerical value from 2 to 32, and the mnpd parameter can have any value from 0 (disabled) to 60. To disable the video performance optimization feature, reverse the disable and enable values noted above, set the queue depth to automatic, and set mnpd to 0, as in the second example command.
  • Page 62 When you use the drives parameter you can list each drive individually, you can specify a drive range, or you can specify both a range and some individual drives. A drive range can span ports, boxes, and bays. If you specify individual drives, they do not have to form a continuous sequence. If you specify a range, the CLI automatically excludes from the target any drive in the range that is unavailable (for example, a drive is excluded if it already belongs to an array, is a spare, has too small a capacity, or has failed).
  • Page 63 1+0 (default value) Now, create the new array: => ctrl ch="Lab 4" create type=ld drives=1:13,1:14 size=300 raid=1+0 It is not strictly necessary to specify the RAID level in this example because it is the highest possible level for this scenario and will be used by default. However, it is included in the command as an example. Now, verify that the array has been formed: =>...

  • Page 64: Viewing Enclosure Information

    ctrl slot=1 ld 3 modify drives=2e:1:1-2e:1:4 ctrl slot=1 ld 3 modify drives=? // shows the available drives You can use the drivetype parameter to specify the drive interface type. When selecting all physical drives, and multiple drive types exist, you must specify the drive interface type. Mixed drives are not allowed on the same array or logical drives.

  • Page 65: Managing Spare Drives

    Syntax: <target> show ssdinfo [detail | summary] Command examples: controller slot=1 show ssdinfo controller all show ssdinfo controller all show ssdinfo detail controller all show ssdinfo summary 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 66 Setting the spare activation mode The spare activation mode feature enables the controller firmware to activate a spare drive under the following conditions: • When a data drive reports a predictive failure (SMART) status • 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.
  • Page 67 You can shrink the size of an array by removing a drive from an existing array. Observe the following criteria: • After the shrink, the array must have sufficient capacity to contain all of the configured logical volumes. • You may not remove drives from the array if the resulting number of drives does not support the fault tolerance (RAID level) of any existing logical drive.
  • Page 68 => 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. You can replace an array by designating different physical drives for the array. To replace the array, each of the physical drives where the array will reside must meet the following criteria: •...
  • Page 69 => ctrl slot=4 ld 1 modify size=? => ctrl slot=3 ld 2 modify size=500 forced Migrating a logical drive This command enables you to adjust the stripe size (data block size) or RAID level of a selected logical drive. For more information, see "Selecting a RAID method (on page 117)." Consider the following factors before performing a migration: •...
  • Page 70 Assigning a redundant controller to a logical drive When you have set the preferred path mode ("Setting the preferred path mode" on page 69) 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 71 • At the low setting level, normal system operations take priority over an array expansion. • At the medium setting, expansion occurs for half of the time, and normal system operations occur for the rest of the time. • At the high setting, the expansion takes precedence over all other system operations. Syntax: <target>...
  • Page 72 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 84 PreferredPath If you select the Manual setting for PreferredPathMode (on page 79), use the PreferredPath command to specify the path for I/O to the logical drive on a redundant controller in active/active mode. The default setting for this option is 1. With this setting, the controller in chassis slot 1 is the preferred controller for I/O to the logical drive.
  • Page 85 Do not mix Renumber and Join operations in the same script, because ACU Scripting does not update its internal state after a renumber. If other commands are mixed with Renumber, commands targeting specific volumes might target the incorrect volume. Repeat The value you enter for this option specifies the number of times that ACU is to repeat this logical drive configuration.
  • Page 86 CAUTION: Back up all data before extending a logical drive. SizeBlocks This option specifies the size of the logical drive in 512-byte blocks. Use this option to set an exact size without rounding. When ACU Scripting captures a configuration, it reports volume sizes rounded down to the nearest MB. When the capture is played back, the size is reduced to fit within the already rounded MB size.

  • Page 87: Hba Category

    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. • In Reconfigure action mode, the default value for this option is the strip size that is already configured for the logical drive.

  • Page 106: 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 107 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 108: 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 109: 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 110: 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 111: 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 112 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 113: 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 114 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 115: 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 116: 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 118 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.
