Breaking a channel path connection that is not the last connection to a coupling facility

When you disconnect a CF sender channel path connection that is not the last connection for a coupling facility, HCD deletes two coupling facility device definitions in the IODF. When you disconnect a CF peer channel path connection that is not the last connection for a coupling facility, HCD deletes Start of changea corresponding number ofEnd of change coupling facility device definitions in the IODF. For both the CF sender channel path disconnection and the CF peer channel path disconnection, HCD also changes the existing coupling facility control unit definition to reflect the channel path disconnection in the IODF.

Perform the following steps when you disconnect a CF sender or a CF peer channel path that is not the last channel path connection to the coupling facility:

  1. Disconnect a CF channel path from the CF receiver channel path, or disconnect the two CF peer channel paths.
  2. Configure the disconnected channel path offline.
  3. Start of changeComplete software only changes with hardware validation.End of change
