Abstract
Migration management is provided for a shared memory logical partition migrating from a source system to a target system. The management approach includes managing migration of the logical partition from the source system to the target system by: transferring a portion of logical partition state information for the migrating logical partition from the source system to the target system by copying at the source system contents of a logical page of the migrating logical partition into a state record buffer for forwarding to the target system; forwarding the state record buffer to the target system; and determining whether the migrating logical partition is suspended at the source system, and if not, copying at the target system contents of the state record buffer to paging storage of the target system, the paging storage being external to physical memory managed by a hypervisor of the target system.
