IPC: G06F13/00
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To make usable a check point/roll-back processing function even when an unsupported I/O device is loaded. SOLUTION: When any I/O device which is likely to generate any malfunction at the time of access after roll-back processing exists, necessary setting for error-ending an I/O request from a host system is executed to the device driver of the I/O device (a step S206). Thus, it is possible to error-end all the I/O requests issued from an operating system or the like to the I/O device by the device driver after roll-back processing, and to inhibit any access to the I/O device after roll-back processing (a step S208). Therefore, it is made possible to perform the roll-back processing at the time of the generation of any failure without generating the destruction of media or data in the I/O device.
