Abstract
The present invention provides a data migration management apparatus that can easily create a re-execution task for re-executing an error-terminated data migration task, and also can increase the possibility of the re-execution task being successful. In a case where a data migration from a migration-source volume to a migration-destination volume fails, the management apparatus uses the information of the failed task to create a re-execution task. The management apparatus changes the configuration of a volume pair as necessary. The management apparatus manages the failed task in association with the re-execution task.
Claims18
An apparatus for performing data migration of an information processing device having a plurality of storage areas, comprising:
- a memory configured to store a migration plan including a storage area of a migration source and a storage area of a migration destination as a task in a task management table;
- and
- a microprocessor configured to execute the migration plan,
- wherein the microprocessor is configured to:
- obtain information related to a storage area of a migration source and a storage area of a migration destination;
- obtain a copy speed from migration history information when there is migration history information which shows migration history from a same or similar storage area with the storage area of the migration source to the same or similar storage area with the storage area of the migration destination, and calculate a data migration time required for data migration by dividing a size of data which is migrated from the storage area of the migration source to the storage area of the migration destination at the copy speed;
- and
- indicate the calculated data migration time associated with an identifier of the task.
A method of performing data migration of an information processing device having a plurality of storage areas, comprising:
- storing, in a memory, a migration plan including a storage area of a migration source and a storage area of a migration destination as a task in a task management table;
- and
- executing, by a microprocessor, the migration plan,
- wherein the executing comprises:
- obtaining information related to a storage area of a migration source and a storage area of a migration destination;
- obtaining a copy speed from migration history information when there is migration history information which shows migration history from a same or similar storage area with the storage area of the migration source to the same or similar storage area with the storage area of the migration destination, and calculating a data migration time required for data migration by dividing a size of data which is migrated from the storage area of the migration source to the storage area of the migration destination at the copy speed;
- and
- indicating the calculated data migration time associated with an identifier of the task.
A non-transitory computer readable medium storing computer program product, which, when executed by a computer, performs data migration of an information processing device having a plurality of storage areas, the data migration comprising:
- storing a migration plan including a storage area of a migration source and a storage area of a migration destination as a task in a task management table;
- and
- obtaining information related to a storage area of a migration source and a storage area of a migration destination;
- obtaining a copy speed from migration history information when there is migration history information which shows migration history from a same or similar storage area with the storage area of the migration source to the same or similar storage area with the storage area of the migration destination, and calculating a data migration time required for data migration by dividing a size of data which is migrated from the storage area of the migration source to the storage area of the migration destination at the copy speed;
- and
- indicating the calculated data migration time associated with an identifier of the task.
