description A method and apparatus migrates partition memory in a logically partitioned computer system by utilizing input/output (I/O) space located outside the logical memory blocks (LMBs) to be migrated. The transmit/receive (X/R) queues that are used by network storage adapters and any fixed memory items such as transmit/receive buffers are placed outside the logical memory blocks (LMBs) of the partition. Without the fixed memory items, these LMBs may be migrated without affecting the operation of the network storage adapters or the software in partition memory. The I/O space may be placed outside the partition in a specialized LMB that holds fixed memory items for one or more I/O adapters.
