• Set the QueueDepth to one of the following values: 2|4|8|16|32|Automatic Array category The Array category has the following options: • Array (on page 76) • CachingArray (on page 76) • Drive (on page 76) • DriveType (on page 77) • Join (on page 77) • OnlineSpareMode (on page 77) • OnlineSpare (on page 78) • Split (on page 78) 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. CachingArray This option specifies the Caching Array ID. • In Configure mode, ACU creates a new caching array. The value that you specify for the array option must be the next available array letter in the existing configuration. AA follows Z, and BA follows AZ. • In Reconfigure mode, the array letter identifies an existing array, or it can identify the next available array letter in the existing configuration to create a new array. 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. HP Array Configuration Utility 76

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.
CachingArray
This option specifies the Caching Array ID.
•
In Configure mode, ACU creates a new caching array. The value that you specify for the array option
must be the next available array letter in the existing configuration. AA follows Z, and BA follows AZ.
•
In Reconfigure mode, the array letter identifies an existing array, or it can identify the next available
array letter in the existing configuration to create a new array.
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.
