ABSTRACT:
A mechanism for establishing a logical relationship between a channel and a control unit, called a logical channel path, in a computer input/output system wherein a dynamic switch is provided between the channel and the control unit. The disclosed logical path mechanism provides for the sharing of the same physical path by one or more channels to one or more control units. The initialization procedure disclosed identifies each sharing channel to each control unit configured to that channel for identifying the physical path to that channel in an input/output system wherein a switch between the channels and the control units provides a multipoint topology.
