FACILITATING TRANSPORT MODE INPUT/OUTPUT OPERATIONS BETWEEN A CHANNEL SUBSYSTEM AND INPUT/OUTPUT DEVICES |
摘要 |
A method of performing an input/output operation includes: generating by a channel subsystem at least one command message including one or more device command words (DCWs), at least one DCW including a data count and a suppress-length indication (SLI) configured to instruct a control unit whether to continue to perform the I/O operation in response to an incorrect length condition; forwarding the at least one command message to the control unit; receiving an incorrect length (IL) value from the control unit and storing an IL indicator in a subchannel-status word, the IL indicator representing the IL value, the IL value being a first IL value in response to a first SLI value and the data count not matching the amount of data required, the IL value being a second IL value in response to a second SLI value and the data count not matching the amount of data required.
