•In Reconfigure mode, ACU can either create a new array or reconfigure an existing array. In this case, the letter value that you specify can identify an existing array, or it can correspond to the next available array letter in the existing configuration.

OnlineSpare

•In Automatic mode, the choices are Yes and No.

•In Configure mode, the default setting is Yes.

•In Reconfigure mode, ACU ignores this option and keeps any spares that the existing configuration already has.

•In Custom mode, you can specify exactly which drives are to be used as spares. If you specify None, any existing spares are removed from the array.

•In Configure mode, the default value is None.

•In Reconfigure mode, the default setting keeps any existing spares in the array.

Drive

List each physical drive that you want to use in the array. Use whichever convention (Port and ID, Box and Bay, or Port, Box, and Bay) is applicable, and follow the formatting suggested in the sample script.

In Automatic mode, all available drives are used.

NOTE: You can use this option to add drives to an existing array (that is, to expand the array), as long as the capacity of the added drives is no less than that of the smallest existing drive in the array. You can also use this option to remove drives from an array if you first set the value of the ClearConfigurationWithDataLoss option to Yes.

•ConnectionName (on page 39)

•HostMode (on page 39)

LogicalDrive

Specify the ID number of the logical drive that is to be created or modified.

•In Configure mode, you can enter only the ID number of the next possible logical drive in the sequence for the existing configuration.

•In Reconfigure mode, you can also enter the ID number of an existing logical drive.
