IBM z13s - Example of C02 with Three CBU Features

348 IBM z13s Technical Guide
The test CBU has a 10-day limit, and must be deactivated in the same way as the real CBU,
using the same facility through the SE. Failure to deactivate the CBU feature before the
expiration date can cause the system to degrade gracefully back to its original configuration.
The system does
not deactivate dedicated engines, or the last of the in-use shared engine.
CBU example
Figure 8-16 shows an example of a CBU operation. The permanent configuration is C02, and
a record contains three CP CBU features. During an activation, you can choose among many
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.
Figure 8-16 Example of C02 with three CBU features
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.
