    Overview Array and controller configuration You can configure arrays and controllers during the initial provisioning of the server or compute module and at any time after the initial configuration. Configuration tasks can be initiated using Smart Storage Administrator (accessible through EXPRESSBUILDER) or the System Utility. During the initial provisioning of the server or compute module, an array is required to be configured before the operating system can be installed.

    The boot controller is the first controller that the system examines (after power up) to find a bootable logical drive or volume. The controller boots from the first logical drive by default. NEC recommends leaving the default setting in place. This will prevent an error when booting after replacing the boot volume or controller.

After you have set the target, any command that you enter in the CLI without a specified is automatically applied to the set target.

  • Page 49 however, it is often easier to specify every drive in the array than to parse out the array ID. 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.

For example, in an existing array, three 72-GB SAS drives (1e:1:4-1e:1:6) are the source. Another drive of the same size is the spare (1e:1:9). With all criteria met, you can move the array to three different 72-GB SAS drives by specifying the new destination drives in the command (1e:1:12-1e:1:14).
  • Page 56 Syntax: modify size=#|max|? [forced] where is a logical drive. 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.

    The options for each category are listed in the following table and described in more detail in the remainder of this section. Category Options Description Action These options define the overall behavior of SSA when it Control Method processes scripts and creates configurations. Control options can occur only once in a script file and must be listed first.

External controllers can be identified by appending the Port Number.
  • Page 68 IRPEnable This option is not supported. LicenseKey, DeleteLicenseKey These options are not supported. MNPDelay This option is not supported. NoBatteryWriteCache With this option, the controller can enable write cache when no battery is present or when the battery fails. Values are Enable or Disable. The default is Disable. Some controllers do not support this option.
  • Page 69 The allowable cache ratios depend on the controller model and whether it has battery-backed write cache. RebuildPriority, ExpandPriority These options establish the priority for rebuild and expand functions. Rebuild has four possible values: Low, Medium, MediumHigh, and High. MediumHigh is only available when Rapid Parity Initialization is enabled. Expand has only three possible values: Low, Medium, and High.
  • Page 70  In Configure mode, SSA creates a new array. The value that you specify for the array option must be the next available letter or pair of letters in the sequence, according to the number of existing arrays on the controller.
  • Page 71 DriveType This option specifies the interface type for drives that SSA Scripting must use to build the array. Choose one of the valid drive types: [SCSI | SAS | SATA | SATASSD | SASSSD] The value is often used with the wildcard (*) or number argument for Drive. OnlineSpareMode The value for this option specifies the behavior of the spare drives when they are activated.
  • Page 72 SplitMirror uses the following commands:  SplitWithBackup: The mirrored array is split into two new arrays and the newly created array is hidden from the OS.  Rollback: The two arrays are recombined using the backup array as source data. Any changes made to the online array are lost.
  • Page 73  In Configure mode, SSA accepts only the ID number of the next possible logical drive.  In Reconfigure mode, SSA also accepts the ID number of any existing logical drive. Caching logical drives and cached data drives must be on the same Array Controller. CachedLogicalDrive The value that you enter for this option specifies the data logical drive ID number to associate with the Caching logical drive.
  • Page 74 Do not mix Renumber and Join operations in the same script, because SSA 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 SSA is to repeat this logical drive configuration.
  • Page 75 without rounding. When SSA 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. This option prevents the loss of volume size over successive generations of captures. However, if the size does not fit the geometry of the array, caused by different disks or RAID levels, the size will be rounded down to fit the geometry.
  • Page 76 Split/Join scripting The SPLITMIRROR command enables you to split or join arrays and their associated drives. It is possible to execute the command only after starting the script with the -offline command in the CLI. The target volumes for the join operation cannot be in use by the operating system. Initial configuration example In this example, two arrays are each set up with a logical drive, and three physical drives (PDrives) between them.

    Basic scripting scenarios Configure a two-disk array Task Create a simple two-disk array with a 100 GB RAID 1 logical volume. Hardware configuration  Storage system  An unconfigured RAID Controller in slot 1 If the controller contains an existing configuration, the script fails unless you add the -reset parameter to the command line to clear the existing configuration.
  • Page 79 Summary The script modifies the size of the logical drive only, because multiple transformations of a logical drive cannot be performed at the same time. For example, SSA Scripting must complete the size expansion before beginning another transformation, such as a RAID level change. To modify existing arrays and volumes, the SSA GUI may be a more intuitive tool for some users.
  • Page 80 Controller=Slot1 Array=A Drive=2 DriveType=SAS Logic alDrive=1 RAID=0 Summary This script does not specify a size, but uses the MAX default value to consume the fully available capacity of the physical drives. SSA Scripting does not support arrays with mixed drive types. An array must comprise drives of the same type, for example all SAS or all SATA drives.

Example Add one array to the configuration, regardless of how many arrays already exist: Controller=Slot1 Array=Next Drive=1E:1:1, 1E:1:2...
  • Page 83 Drive=N You can use Drive=N instead of specifying the actual paths (Drive=1E:1:1, 1E:1:2). Advantage You can specify the number of drives needed for the configuration, and the scripting software selects the first available drives based on increasing path. This command is most useful when all drives in the configuration are the same size.
