•
Set the MNPDelay to any integer value from 1 to 60 (units are minutes). If you want to disable this
option, set a value of zero instead.
•
Set the QueueDepth to any integer value from 2 to 32, or to Auto.
Array category
The Array category has the following options:
•
•
•
•
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 to add a drive to an existing array (to expand an array) or to build a new array. 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 the value of the ClearConfigurationWithDataLoss (on page
) option is Yes, you can use the
Drive option to remove drives from an array. However, the ClearConfigurationWithDataLoss
option is now deprecated.
If you 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.
If you use Custom method mode, choose one of the following methods to specify the drives to be used in the
array. (Different arrays on the same controller can use different methods.)
•
To specify individual drives, use the applicable convention (port:ID, box:bay, or port:box:bay).
•
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.
•
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.
