Unit checks report peripheral subsystem error conditions at the time of error, at a later time within a chain of channel commands, or during a following or unrelated chain of channel commands. A set of channel commands is described that result in delaying reporting of an earlier detected error condition because reporting the error with the instant command could cause data processing errors. The input/output channel commands outside of the restricted set of commands enables the earlier detected error condition to be reported after completion of the restricted input/output command.
