Publication number: 20090077331Abstract: When migrating data stored in a storage region assigned to a volume to another storage region, the connection status of the host computer and volume is confirmed. When the host computer and volume are connected, the maximum capacity of the volume requested by the host computer is reserved so that it is exclusively secured in another storage region to which data is to be migrated, and when the host computer and volume are not connected, the current capacity of the volume is reserved so that it is exclusively secured in another storage region.Type: ApplicationFiled: November 6, 2008Publication date: March 19, 2009Inventors: Tsukasa Shibayama, Wataru Okada, Yukinori Sakashita, Yuri Hiraiwa, Masahide Sato

Publication number: 20090077336Abstract: This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus.Type: ApplicationFiled: November 12, 2008Publication date: March 19, 2009Inventors: Tsukasa Shibayama, Wataru Okada, Yukinori Sakashita, Yuri Hiraiwa, Masahide Sato
