Patent attributes
In accordance with embodiments of the present disclosure, a system may include a first storage controller for managing a Redundant Array of Independent Disks (RAID) comprising a plurality of disk drives and a second storage controller for managing at least one disk drive other than the plurality of disk drives. The first storage controller may be configured to: (i) in response to the RAID having a degraded state and the first storage controller not having an available hot spare disk drive local to the first storage controller, communicate a request for a hot spare disk drive of another storage controller; (ii) receive a response to the request identifying a disk drive of the second storage controller as an alternative available hot spare disk drive; and (iii) communicate with the second storage controller to use the alternative available hot spare disk drive to rebuild the RAID.
