ABSTRACT:
In a multiple-CPU, dynamic path allocation environment. The environment, several devices, such as input/output (I/O) devices, may be accessed through one of a plurality of dynamically configured paths from the CPU. Each path includes a channel, from the CPU, connected to a director. The director, in turn, is connected through respective control module interfaces, to a plurality of control modules, which control modules are used to access a string of devices. The connection method, carried out under control of the director, includes simultaneously polling all of the control modules to determine if any have devices attached thereto that are ready to be connected to the CPU. A response from the control modules, all received simultaneously at the director, identifies the CPU channel through which the connection is to be made. The specific address of the device to be connected is then determined, and the desired connection from the CPU to the device is completed.
