26 Hardware Management Console (HMC) Case Configuration Study for LPAR Management
Example of using two uncapped partitions and the weight

For the example of two uncapped partitions using the same shared processor

pool, we use the configuration described in Table7.

Table 7 CPU allocation table

We created a heavy CPU load on both uncapped partitions and verified their load

using the topas -L command.

Example 11 and Example 12 are the outputs of the topas -L command from

nodes oli and julia, including the same weight value.
