摘要： A computer Input/Output system having a fabric, a control unit (CU) and a host computes including a channel, the channel having a channel port connected by a first link to a channel neighbor port of the fabric, and the control unit having a CU port connected by a second link to a CU neighbor port on the fabric. When an error is detected in the link or protocol between the channel and the control unit, after a retry of the failing operation is performed, error data are reported to the channel by the channel, the channel port, the channel neighbor port, the control unit, the Cu port and the CU neighbor port and sent to the channel. The error data are provided to the host computer for analysis.
