  • Data processing apparatus, data processing method, and data processing program
    Patent number: 11055024
    Abstract: In a computer which controls data access with respect to a prescribed logical unit, a processor is configured to: perform, when data access by one path with respect to a logical unit is not completed, control for switching paths with respect to the logical unit; perform communication control in accordance with SCSI with the logical unit by executing a SCSI driver; accept a path interchange time that is a time used as a reference for switching paths with respect to the logical unit; determine an upper limit number of retries in data access by the one path on the basis of the path interchange time; and perform control so that an upper limit number of retries using the one path by the SCSI driver equals the determined number of retries.
