7. Make several changes here, based on the resources you want to set for the i5/OS
partition. You need to assign the CPU and memory allocation according to the
planning
you completed with the Logical Partitioning Validation Tool (LVT). We examine all of the
changes step-by-step as highlighted in Figure 13-9.
Figure 13-9 Change Partition Configuration Options
򐂰 Minimum / Maximum Number of Processors: Here, you enter the value for the
minimum number of processors that you will need for your i5/OS environment, and the
maximum number of processors that will be available for i5/OS. In our sample
environment, we had 2 processors and we left the maximum value at 2 – enabling i5/OS
to utilize all of the processors if the Linux partitions are not being used.
򐂰 Use Shared Processor Pool: The shared processor pool is a group of physical
processors that provide processing capacity that can be shared among multiple logical
partitions. The shared processor pool allows you to assign partial processors to a logical
partition. In our example, since we are going to create four additional Linux partitions, we
would not have sufficient resources to allocate a full processor for every partition. Another
advantage for changing the partition configuration to use the shared processor pool is that
the partition will have the capability to use processor resources unused by other partitions.
Note: When the current value of 2 is changed to 1, indicating that the shared processor
pool is desired, the system prompts for new shared processor pool values once the Enter
key is pressed.
