ABSTRACT:
Provided are a method, system, and program for managing path groups to an Input/Output (I/O) device. Indication is made of a connection path on which a processing system initially communicated an establish request to establish a connection with an I/O device, wherein attention that the processing system may own a lock for the I/O device is transmitted down the indicated connection path. A request is received from the processing system to add a path to a path group with respect to the I/O device, wherein the added path is capable of comprising the connection path the processing system used to establish the connection with the I/O device. The received path is added to the path group.
