ABSTRACT:
Provided are a method, system, and program for managing access to a device. An I/O request directed toward the device is received and a determination is made of a device object for the device associated with at least one path object. A determination is made of a queue object associated with the device object, wherein the queue object corresponds to one queue. A determination is made of a queue status from the determined queue object and the I/O request is transmitted on a path indicated in the path object that is associated with the determined device object if the queue status is set to a state indicating to transmit I/O requests.
