Zusammenfassung:A storage architecture and method for managing the operation of a network in a RAID environment is provided in which a storage management agent is included in each server node of the network. The storage management agents monitor the status of the drives of the storage array in shared storage. If a storage management agent identifies a failed drive, the storage management agent monitors the rebuild of the degraded RAID volume. During the rebuild of a degraded RAID volume, the storage management agent determines if a server node has failed, and, if required, initiates the transfer of the RAID rebuild tasks of the failed server node to another server node.
