•
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 79) 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:
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
o
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.
To use all available drives, enter an asterisk as the value for this option. An array that is
o
configured using this method cannot have a spare.
DriveType
The value that you enter for this option specifies the type of drive (SAS, SATA, or parallel SCSI) that ACU
must use to build the array.
OnlineSpare
The value for this option determines whether the array specified previously in the script will be configured
with spare drives.
