Abstract:
A method, apparatus, and computer program product for processing a chain linked transport control channel program in an I/O processing system is provided. The method includes receiving a first command message at a control unit specifying a first predetermined sequence number for performing a first set of one or more commands as part of an I/O operation. The method further includes receiving a second command message specifying a second predetermined sequence number for performing a second set of one or more commands as part of the I/O operation. The method also includes comparing the sequence numbers to a next expected predetermined sequence number to determine an order of performing the commands. The method additionally includes executing the commands in the determined order to perform the I/O operation.
