Adding Processors to a Logical Partition

Use this procedure to use the Hardware Management Console (HMC) to add processors to a partition without rebooting the partition's operating system.

You can only add up to the amount of free system processors. This number also cannot exceed the maximum number specified in this partition's active profile. To learn more about the resources being used by the activated partition, select the Details tab of this partition's Properties folder. To learn more about the partition's active profile, look at the activated profile's properties.

  11. In the Task timeout field, select the number of minutes you want the system to wait before it stops the adapter dynamic reconfiguration task.
