Interaction with processor sets Dynamic nPartitions is fully integrated with processor sets. If the attributes of a processor set are established so that it is not allowed to become empty, then the last SPU in that processor set cannot be online deactivated. If a cell online deactivation operation would cause the processor set to become empty, then that operation will not complete successfully. Cell reset recovery time When a cell is deactivated online, it is reset to prepare for its next use. The reset operation does a full initialization, so it takes approximately 1 minute. During this time the cell can not be reactivated nor assigned to another partition. During the reset recovery time, parstatus shows the state of the cell as "Powering on". Summary Dynamic nPartitions operations complete the value proposition of partitionable server complexes. Vast flexibility can be realized through changing the composition of nPartitions while continuing to run their application workloads. Many real-world scenarios can benefit from timely use of Dynamic nPartitions. Advance planning in the configuration of the system complex can maximize the benefits of Dynamic nPartitions functionality. 10
