    摘要: An apparatus, system, and method are disclosed for global metadata copy repair. The apparatus includes a control module for copying global metadata from primary storage to target storage, a verification module configured to identify invalid track in the global metadata, a location module configured to maintain a current read address, and a read module configured to find a valid copy of the invalid track. The system includes a plurality of hosts, a storage controller in communication with the plurality of hosts over a network, a primary storage device, a target storage device, and the apparatus. The method includes copying global metadata from a primary storage device to a target storage device, identifying invalid track in the global metadata of the primary storage device, maintaining a current read address of a buffer read, and finding a valid copy of the invalid track.
