b.Record existing nonboot disks under submirror 19, and empty slots for new nonboot disks under submirror 20.

Example: Imagine a system that already has two disk drives in slots 0 and 1. In the previous step, you would have reserved slot 2 for the second boot disk. The remaining new disk is a nonboot disk and will be installed in slot 3. So you would record the following values in the table:
