Node oli and node julia have 1.0 processor units entitled and 100% CPU usage.
The shared processor pool has 3.0 units, so the idle capacity is 1.0 unit shared
by partitions julia and oli, proportionally to their weight. In our case, partition oli
adds 255/(255+128) from 1.0 processing units, while partition julia adds
128/(255+128) processing units.
Automating HMC tasks
In this section, we describe an example of using the HMC scheduler to perform a
dynamic LPAR operation. The example uses 2 partitions in shared mode on a
system with 4 CPUs and 8 GB of RAM. Our partitions' configuration is described
in Table 8.
