Control category

The Control category has two options: Action (on page 34) and Method (on page 34).

Action

You must specify an Action mode.

•In Configure mode, you can create new arrays, but you cannot modify existing arrays. The controller must be connected to unassigned physical drives for this mode to be available.

•In Reconfigure mode, you can modify existing arrays. For example, you can set up an array expansion, a logical drive extension, or a migration. These procedures do not destroy data, unless you specifically want the data to be deleted. In this mode, ACU does not change an existing option setting unless you specifically script a different value for that option.

Method

The default value for this option is Automatic. If you want to use Custom mode, you must specify it.

In Automatic mode, ACU can perform an expansion, extension, or migration without user intervention if the values that you set for other options imply that such an operation is necessary.

Controller category

The following options are available under the Controller category:

•Controller (on page 35)

•ClearConfigurationWithDataLoss (on page 35)

•LicenseKey ("LicenseKey, DeleteLicenseKey" on page 35)

•DeleteLicenseKey ("LicenseKey, DeleteLicenseKey" on page 35)

•RAIDArrayID (on page 35)

•ReadCache ("ReadCache, WriteCache" on page 35)

•WriteCache ("ReadCache, WriteCache" on page 35)

•RebuildPriority ("RebuildPriority, ExpandPriority" on page 36)

•ExpandPriority ("RebuildPriority, ExpandPriority" on page 36)

•SurfaceScanDelay (on page 36)

•SSPState (on page 36)
