Abstract
Methods and structure for migrating logical volumes are provided. The system includes a Redundant Array of Independent Disks controller, which includes a Peripheral Component Interconnect Express interface, a Serial Attached Small Computer System Interface port operable to communicate with another Redundant Array of Independent Disks controller, and a command unit. The command unit is able to direct the interface to access another Peripheral Component Interconnect Express interface at the other controller, to synchronize with Disk Data Format information from a Peripheral Component Interconnect Express Inbound Map of the other interface, to detect that the other controller has failed, and to utilize the Disk Data Format information to migrate a logical volume from the other controller to the controller.
