5. Select option 3. Work with partition configuration, as shown in Figure 13-6.
The objective of the next few steps is to ensure that we remove processing and memory
resources from the i5/OS partition so that we can create Linux partitions. It is important that
you complete the sizing exercise for your overall CPU and memory utilization for your i5/OS
workloads to account for removal of such resources. Also take into account the overheads
associated with micro-partition processor allocation. For more information, see the
Whitepaper on i5/OS LPAR performance on POWER4 and System i5 systems.
Note: Option 1: Display Partition Information is not enabled for Virtual Partition Manager.
Instead, use Option 2: Work with Partition Status, or use Option 3: Work with Partition
Configuration to manage logical partitions using Virtual Partition Manager.
