ABSTRACT:
A dynamic switch connects a control unit to a plurality of channels on one or more processors, each processor controlled by an operating system. A logical path scheduler (LPS) within a master operating system in one of the processors contains a path control table which contains an entry for each control unit, system, and logical path combination--each entry indicating current path status (connected or disconnected), and time in that status. I/O requests within the systems for which no path currently exists are queued, and the LPS initiates connections and disconnections for the paths to equitably allocate the maximum number of simultaneous path connections allowed for the control unit, among more than that maximum number of contending channels.
