Hardware Management Console (HMC) Case Configuration Study for LPAR Management 21
At the time node nils is back and ready to reacquire the applications running on
node julia, we reduce the memory and CPU to the initial values and turn off CoD.
In order for node julia to operate with the initial resources, we have to remove 1.8
processing units and 6 GB memory from this partition.
1. Perform dynamic LPAR operations to decrease the CPU units and memory
capacity of the target partition.
The following steps are taken to decrease the CPU units and memory capacity of
the target partition.
Perform the dynamic LPAR operation for CPU.
– Using the graphical interface on the HMC.
In the Server and Partition panel, right-click partition julia and select Dynamic
Logical Partitioning → Memory Resources → Add. In the dialog window,
enter the desired amount of memory to remove as shown in Figure 11.
