Managing the establishment of logical paths

You can manage the establishment of logical paths between channels and control units. With proper planning, you can create I/O configuration definitions that allow control units in the configuration to allocate logical paths for every possible request made by channels in either of the following ways:
  • Create a one-to-one correspondence between the logical path capacity of all control units in the physical configuration and the channels attempting to request them.
  • Create I/O configurations that can exceed the logical path capacity of all or some of the control units in the physical configuration but, at the same time, provide the capability to selectively establish logical connectivity between control units and channels as needed.
