Toolkit utilities 45
• Method mode (on page 45)
Action mode
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 mode
The default value for this option is Auto. If you want to use Custom mode, you must specify it.
In Auto 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.
