Provided are a method, system, and device for signaling a reconnection inhibitor over a bus to cause the reconnection inhibitor to access the bus to inhibit an Input/Output (I/O) controller from accessing the bus. An initiator transmits I/O requests on the bus to the I/O controller, wherein the I/O requests are queued in an I/O queue, wherein the I/O controller is inhibited by the reconnection inhibitor from draining the queue while the initiator transmits requests to the I/O controller.
