The value that you enter for this option
specifies the ID number of the logical drive that is to be created
or modified. The first logical drive on an array must have an ID of
1 (not 0), and logical drive numbering must be contiguous.
In Configure action mode, ACU accepts only
the ID number of the next possible logical drive.
In Reconfigure action mode, ACU also accepts
the ID number of any existing logical drive.
