(a), (b), (c), and (d) in the screen are described as follows.
(a) General Setting
LD Setting
The number of LDs and the LD Capacity are specified here. It is also possible to specify either of them.

When only the LD Capacity is specified, the maximum number of logical disks that can be created is
calculated.
If having specified LD Capacity, you can either enter a numeric value or specify a bound logical disk.

Selecting a logical disk from the list makes it possible to bind another logical disk having the same capacity as
that selected one. If a logical disk cannot be selected, the "Not Specify Reason" field displays one of the
reasons:
