System disk pool
One system disk pool exists per system. The system automatically creates the system disk pool (Disk Pool 1), which contains disk unit 1 and all other configured disks that are not assigned to a basic or independent disk pool. The system disk pool contains all system objects for the i5/OS® licensed program and all user objects that are not assigned to a basic or independent disk pool.
You can have disk units that are attached to your system but are not configured and are not being used. These are called non-configured disk units.
