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.
