Abstract:
1. A test method, comprising: executing a data transfer instruction with regard to transfer of data between a plurality of multiplexed storage devices and a plurality of main systems logically connected to the plurality of storage devices; storing an initial value of an operand upon execution of the data transfer instruction; re-setting the stored initial value to the operand upon occurrence of an interrupt triggered by an exception; repeatedly executing the data transfer instruction and re-setting the stored initial value to the operand, by a main system accessing the storage device, until the data transfer instruction is completed normally; storing information that indicates one of a data transfer completed portion and a data transfer non-completed portion, upon the occurrence of the interrupt triggered by the exception, in storing the initial value of the operand; and repeatedly executing the data transfer instruction and re-setting the initial value to the operand for the data transfer non-completed portion, by the main system accessing the storage device, based on the information that indicates one of the data transfer completed portion and the data transfer non-completed portion, until the data transfer instruction is completed normally.
