A logical path is a logical connection between a control unit and a FICON® channel (TYPE=FC). Logical paths are important because each sharing LP on a CPC requires that a logical path is established between a FICON channel and a control unit for I/O operations to occur.

Logical paths do not exist for coupling facility channel paths, CE LR (TYPE=CL5, TYPE=CL6), ICA SR (TYPE=CS5) coupling links, internal coupling channel paths (TYPE=ICP), Open Systems Adapter channel paths (TYPE=OSC, TYPE=OSD, or TYPE=OSE), internal queued direct communication (HiperSockets) channel paths (TYPE=IQD), or fibre channel protocol channel paths (TYPE=FCP).
