Title:
METHOD AND DEVICE FOR PROVIDING MULTI-PATH INPUT/OUTPUT USING SCSI-3 DURATION RESERVATION IN NON-OVERLAP CLUSTERING ENVIRONMENT
Document Type and Number:
Japanese Patent JP3659342
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for providing multi-path input/ output in non-overlap clustering environment.
SOLUTION: Shared non-overlap access to logical volume is provided through a plurality of paths using an SCSI-3 duration reservation command. Open option of an operating system is mapped on the SCSI duration reservation command to register all of a plurality of paths in logical unit numbers of a shared storage system, and a plurality of second paths enable access to the logical unit numbers of the shared storage system after acquiring duration reservation to the shared storage system.
