• 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
41 ) 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.
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.
Method mode Possible values Default value
Custom To specify exactly which drives to use as
spares, use the applicable convention (port:ID,
box:bay, or port:box:bay).
To specify only the number of spares (not the
exact IDs), enter that number as the value for
this option. ACU automatically selects only
those drives that are suitable for the array.
To specify that the array should not have
spares, enter None.
In Configure action mode: None
In Reconfigure action mode, ACU
ignores any value entered for this
option and keeps any spares that
are already present in the
configuration
