Example Of C02 With Three Cbu Features - IBM z13s Technical Manual

Tip: The CBU test activation is done the same way as the real activation, by using the
same SE Perform a Model Conversion window and selecting the Temporary upgrades
option. The HMC windows have been changed to avoid real CBU activations by setting the
test activation as the default option.

Figure 8-16 shows an example of a CBU operation. The permanent configuration is C02, and

target configurations. With three CP CBU features, you can add one to three CPs, which
enable you to activate C03, C04, or C05. Alternatively, two CP CBU features can be used to
change the capacity level of permanent CPs, which means that you can activate D02, E02,
and F02 through Z02.
