Patent ID: 7600056

Claim:
A method of generating a data logout in a computing environment having a processor and an input/output subsystem for receiving data from and sending data to the processor, the method comprising the steps of: the input/output subsystem maintaining a defined set of data; at defined times, the processor issuing a data logout command; sending said data logout command to the input/output subsystem; and in response to receiving said data logout command, the input/output subsystem sending said defined set of data to a specified location; and wherein: the input/output subsystem includes a channel subsystem including a first channel local to the processor, and a second channel remote from the processor, wherein the first and second channels are connected together by a channel interface; the step of sending said defined set of data includes the steps of, in response to receiving said data logout command, the input/output subsystem sending a specified signal across said interface to one of said first and second channels; and in response to receiving said specified signal, said one of the first and second channels sends a subset of the defined set of data to the specified location.
