Method, system, and program for managing path groups to an input/output (I/O) device
First Claim
1. A method, comprising:
- determining at least one logical path to add to a path group to communicate with an Input/Output (I/O) device, wherein the path group indicates multiple paths that are enabled to communicate with the I/O device;
issuing at least one command to a control unit to add the determined at least one logical path to at least one path group to add to the I/O device, wherein the logical path to add is capable of comprising a connection path that was used to establish a connection with the I/O device.

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.

-
a computer readable medium;
circuitry in communication with the computer readable medium and enabled to perform;
(i) indicate in the computer readable medium a connection path on which one processing system initially communicated an establish request to establish a connection with one 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; and
(ii) receive a request 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; and
(iii) add the received path to the path group. - View Dependent Claims (10, 11, 12)
