Abstract
A computer program product is provided for performing a method including: obtaining information relating to an I/O operation at a channel subsystem in a host computer system; generating at least one address control word (ACW) in the local channel memory specifying one or more host memory locations for transfer of data between the host and a control unit and including at least one ACW error checking field; generating an address control structure specifying a location in the local channel memory of a corresponding ACW and including at least one address control structure error checking field; receiving a data transfer request from the network interface that includes the addressing information; comparing the at least one ACW error checking field to the at least one address control structure error checking field; and, responsive to the fields matching, routing the data transfer request to the host memory location specified in the corresponding ACW.
