Abstract:
Provided are a computer program product, system, and method for processing a recall request for data migrated from a primary storage system having data mirrored to a secondary storage system mirroring data from the primary storage system to the at least one secondary storage system. The primary storage system receives a recall request to recall a data object that was migrated from the primary storage system to a remote storage location. The recall request is transmitted to each of the at least one secondary storage system to cause each of the at least one secondary storage system receiving the recall request to directly retrieve the data object from the remote storage location. The primary storage system retrieves the data object from the remote storage location in response to the recall request. The primary storage system returns complete to the recall request in response to the data object being confirmed as restored to the primary storage system and the at least one secondary storage system.
