Abstract
Automated paging device management is provided for a shared memory partition data processing system. The automated approach includes managing a paging storage pool defined within one or more storage devices for holding logical memory pages external to physical memory managed by a hypervisor of the processing system. The managing includes: responsive to creation of a logical partition within the processing system, automatically defining a logical volume in the paging storage pool for use as a paging device for the new logical partition, the automatically defining occurring absent use of a filesystem, with the resultant paging device being other than a file in a filesystem; and automatically specifying the logical volume as a paging space device for the new logical partition and binding the paging space device to the new logical partition, wherein the logical volume is sized to accommodate a defined maximum memory size of the new logical partition.
