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
Auto Yes (indicating one spare)
No
In Configure action mode: Yes
(indicating one spare)
In Reconfigure action mode, ACU
ignores any value entered for this
option and keeps any spares that are
already present in the configuration
Logical Drive category
The Logical Drive category has the following options:
• ArrayAccelerator (on page 45 )
• LogicalDrive (on page 45 )
• LogicalDriveSSPState (on page 45 )
• ParityGroups (on page 45 )
• PreferredPath (on page 45 )
