4.6.2 Storage pools
A storage pool is a single entity that consists of one or more physical volumes or
files. Logical volumes or virtual disks are created within a storage pool. Physical
volumes or file spaces can only be assigned to a single storage pool.
After the installation of the VIOS, a default storage pool is created from space in
the volume group rootvg. A new default storage pool should be created if you
plan to use storage pools. As a general best practice, the storage pool in volume
group rootvg should not be used.
