Array
Enter a letter or pair of letters to identify the array that is to be created or reconfigured, and observe these
additional limitations:
•
In Configure mode, ACU 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. AA follows Z, and BA follows AZ.
•
In Reconfigure mode, ACU can either create a new array or reconfigure an existing array. In this case,
the value that you specify can identify an existing array, or it can correspond to the next available array
letter or pair of letters in the existing configuration.
Drive
You can use this option in the input file to specify new physical drives for the array. Use this option to build
a new array or to expand, shrink, or move an existing array.
Observe the following guidelines:
•
If you are expanding an array, each drive that you add must have a capacity no less than that of the
smallest drive already in the array. The added drives and the existing drives in the array must all be the
same type (for example, SAS or SATA).
•
If you are moving or shrinking an array, ACU Scripting compares the current drives with the requested
drives, and then determines whether you are moving or shrinking. Shrinking or moving an array is
supported only in Custom method mode.
•
If the value of the
ClearConfigurationWithDataLoss (on page
78
)
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.
•
Custom method mode
—To specify the drives to be used in the array (different arrays on the same
controller can use different methods), choose one of the following methods:
o
To specify individual drives, use the applicable convention (port:ID, box:bay, or port:box:bay).
o
To specify only the number of drives to use (not which specific drive IDs to use), enter that number
as the value for this option. For example, if you enter
drive=3,
ACU uses the first three available
drives to build or expand the array that you define in the remainder of the script. ACU automatically
determines which drives are suitable to use.
o
To use all available drives, enter an asterisk as the value for this option. An array that is configured
using this method cannot have a spare.
DriveType
This option specifies the interface type for drives that ACU must use to build the array.
