Single storage pool
With this function, all physical storage is dynamically designated by PR/SM as central storage as requirements of active logical partitions dictate.
As a result, the need to predesignate configured storage as central storage prior to IML on the Storage page of the Customize Activation Profile window is not necessary and is not provided. The system programmer now has greater flexibility when planning the division of storage in order to satisfy anticipated logical partition definitions. Single storage pool streamlines the planning effort because PR/SM automatically provides the correct storage designation for any configuration as the need arises. This feature is especially useful as it simplifies planning for migration to z/OS® a 64-bit capable operation system.
A feature of this function is that the central storage addressability ranges are communicated on the logical partition storage allocation display of the Storage Information task.
