398 Logical Partitions on System i5
2. Assign the values for creating the new Linux partition as per your Logical Partitioning
Validation Tool (LVT) output, as shown in Figure 13-15. A brief explanation of each of the
value is also provided here:
– Partition Identifier and Name: Enter the partition name for your Linux partition. You
can also change the partition identifier should you choose to. In this example, the
default given (next partition identifier number) by the system is selected.
– Number of Partition Processors: If you are defining a Linux partition with dedicated
processors, then enter the value of the processors that will be dedicated to that
partition. For partitions utilizing shared processor pool, you can enter the value of the
number of virtual processors that you plan to utilize in your applications. This value will
also affect how you set up your Min/Max number of processors, and also how you set
up your Min/Max shared processor pool units later. For example, if you set a value of 4,
then the maximum number of processors in the next field (as shown in 3 below) should
also be set to 4. Also, you will need at least 0.40 processing units specified in step 4.
– Minimum / Maximum number of Processors: Enter the value for minimum number
of processors that you will need for your Linux environment, and the maximum number
of processors that will be available for Linux.
– Shared Processor Pool Units: Assuming that you are going to use shared processor
pool, you now need to specify the total number of processing units that will be available
to the partition during start up. 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 to be set up as having a dedicated CPU.
