Managing configurations of input/output system images of an input/output subsystem, wherein a configuration is modified without restarting the input/output subsystem to effect a modification

摘要

An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. One or more input/output subsystem images of the plurality of input/output subsystem images are managed. An aspect of this management includes managing an input/output (I/O) configuration of an input/output subsystem image. This management may be performed dynamically.
