You define installation options, and any installation exits and installation-defined callable services to ICSF. Using the ICSF panels, you can view how these options and programs are currently defined. During master key management, you change the status of the key storage registers that contain key parts and the master keys. You can use the ICSF panels to view the status of these hardware registers. You can also use the ICSF panels to deactivate or activate your cryptographic coprocessors and accelerators.
When you check the status of an installation option, an installation exit, or an installation-defined callable service, you may decide to change how you defined the option or program. You must change the information in the installation options data set and restart ICSF to activate the change.
