one subdisk will not be mirrored.

3. At the following prompt, enter the target disk name (this disk must be the same size
or larger than the originating disk):

available disk space, or you can choose to mirror onto a
specific disk. To mirror to a specific disk, select the name of
that disk. To mirror to any available disk space, select "any".
