coupling facility levels, see “Coupling Facility Planning Considerations” on page
2-39.
Guest Coupling Simulation
Guest coupling simulation is available with z/VM.
z/VM guest coupling simulation allows you to simulate one or more complete
parallel sysplexes within a single system image, providing a test environment for
parallel sysplex installation. The simulated environment is not intended for
production use since its single points of failure diminish the availability advantages
of the parallel sysplex environment. There are no special hardware requirements –
external coupling facility channels, external coupling facilities, and Sysplex Timers
are neither necessary nor supported. Guest operating systems within a simulated
sysplex can only be coupled (through simulated coupling facility channels) to
coupling facilities also running as guests of the same z/VM system. You can have
up to 32 virtual machines running z/OS within a simulated sysplex, with each z/OS
virtual machine coupled to up to 8 virtual machines running as coupling facilities.
There is no system-imposed limit to the number of guest parallel sysplex
environments that z/VM can simulate. However, practical limits on the number of
guests that can be supported by a particular hardware configuration will also
constrain the number of simulated parallel sysplex environments.
Control Program Support in a Logical Partition
Control programs require certain characteristics. Before planning or defining LP
characteristics, call your installation management to determine which control
programs are in use or planned for operation.
Notes:
1. Use IBM Service Link to view the appropriate PSP bucket subset ID for
hardware and software maintenance information.

hardware EC, driver, and MCL numbers and software APAR numbers), see
“Coupling Facility Level (CFLEVEL) Considerations” on page 2-50.
