Abstract:
Technical solutions are described for computing data check word for a host request for an I/O processing operation at a host computer system that communicates with a control unit. An example method includes obtaining information for a first I/O operation at a channel subsystem in the host computer system, and accessing an address control word (ACW) of the first I/O operation. The ACW is stored in the local channel memory, and the ACW includes a first data check seed-value. The method also includes computing a first data check word based on the first data check seed-value from the ACW. The method also includes obtaining information for a second I/O operation at the channel subsystem, and in response to the second i/o operation corresponding to said ACW of the first I/O operation, computing a second data check word based on a second data check seed-value from a cache memory.

Claim (Index 1):
A computer implemented method for computing data check word for a host request for performing an input/output (I/O) processing operation at a host computer system configured for communication with a control unit, the method comprising:\n obtaining information relating to a first I/O operation at a channel subsystem in the host computer system, the channel subsystem including at least one channel having a channel processor and a local channel memory; accessing an address control word (ACW) corresponding to the first I/O operation, the ACW specifying one or more host memory locations for transfer of data between the host computer system and the control unit, the ACW being stored in the local channel memory, the ACW including a first data check seed-value; computing a first data check word based on the first data check seed-value from the ACW; obtaining information relating to a second I/O operation at the channel subsystem; and in response to the second I/O operation corresponding to said ACW that is corresponding to the first I/O operation, computing a second data check word based on a second data check seed-value from a cache memory.
