Abstract
Methods, systems and computer program products for evacuating memory from a drawer in a live multi-node system are provided. Aspects include placing a first drawer into an evacuation mode. The evacuation mode includes a cessation of non-evacuation operations and provides for a transfer of data stored by memory of the first drawer to a destination drawer using dynamic memory reallocation (DMR). Aspects also include transmitting a store request by the first drawer to the destination drawer. The store request represents a request to transfer the data stored by the memory of the first drawer to the destination drawer for storage by the destination drawer. Aspects also include transmitting the data stored by the memory of the first drawer to the destination drawer. The data is transmitted by the first drawer using a local pool of fetch/store controllers.
