You can learn about how the Hardware Management Console (HMC) and Integrated Virtualization Manager allocate and manipulate paging space devices on systems that use shared memory.
A paging space device is a physical or logical device that is used by a Virtual I/O Server to provide the paging space for a logical partition that uses shared memory (hereafter referred to as a shared memory partition). The paging space is an area of nonvolatile storage used to hold portions of the shared memory partition's memory that are not resident in the shared memory pool.
