The Coupling Facility LP is defined through HCD and Processor Resource/Systems Manager (PR/SM) panels on the Hardware Management Console (HMC). Once you have defined an LP to be a coupling facility LP, only the CFCC can run in that LP. When you activate the Coupling Facility LP, the system automatically loads the CFCC from the laptop Support Element (SE) hard disk of the CPC.
Its major functions are:
- Storage management
- Support for CF links
- Console services (HMC)
- Trace, logout, and recovery functions
- Provide support for the list, cache, and lock structures
