18 Hardware Management Console (HMC) Case Configuration Study for LPAR Management
In order for node julia to operate with the same resources as node nils had, we
have to add 1.8 processing units and 6.5 GB memory to this node.
Allocation of processor units.
– Using the graphical user interface.
In the Server and Partition panel on HMC, right-click on partition julia and select
Dynamic Logical Partitioning → Processor Resources → Add. In the dialog
window, enter the desired values for additional processing units and virtual
processors as shown in Figure 9.

– Using the command line interface.
In Example 5, we run the command lshwres on the HMC to get the current
values of the cpu units and virtual processors used by node julia, before and after
increasing the processing units.
Note: If you use reserve CoD instead of ON/OFF CoD to temporarily activate
processors, you can assign the CPUs to shared partitions only.
