Moving Processors between Logical Partitions

You can use the Hardware Management Console (HMC) to move processors from one partition to another without rebooting either partition's operating system.

To move processors from one active partition to another without rebooting either partition, do the following:

  1. Log in to the HMC using either the System Administrator or Advanced Operator roles.
  2. In the Navigation area, click the console's icon to expand the tree.
  3. In the Navigation area, click the Server and Partition folder.
  4. In the Contents area, click the Server Management icon.
  5. In the Contents area, click the managed system's icon to expand the tree.
  6. Select the partition from which you want to move the processors.
  7. From the Selected menu, select Dynamic Logical Partitioning.
  8. Select Processors.
  9. The Dynamic Logical Partitioningwindow opens. Click Move resources to a partition.
  10. Select the number of processors you want to move from this partition.
    11. Note:
    The number you are removing cannot make the remaining number of processors be less than the minimum number specified in this partition's active profile. Likewise, the number you are adding to the other partition cannot exceed the destination partition's maximums. To learn more about the resources being used by each activated partition, select the Details tab of each partition's Properties folder.
  11. Select name of the partition to which you want to move the processors.
  12. In the Task timeout field, select the number of minutes you want the system to wait before it stops the move processor dynamic reconfiguration task.
  13. In the Details field, select the level of feedback you would like to see while the HMC performs the task. Details shown include the operating system's standard output and standard error information.
  14. When you are finished selecting the correct information, click OK. Processors are moved from this partition to the partition you selected.
