HP ProLiant DL380 Server - Manual (Page 44)

Array category
The Array category has the following options:
•
“Array” (page 44)
•
“Drive” (page 44)
•
“DriveType” (page 44)
•
“OnlineSpare” (page 45)
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 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.
