Abstract:
Methods and structure are provided for performing a rebuild using a Serial Attached SCSI (SAS) expander. The SAS expander includes an SMP target operable to receive, from a Redundant Array of Independent Disks (RAID) controller, a Serial Management Protocol (SMP) command for initiating a rebuild of a RAID volume at the SAS expander. The SAS expander also includes a control unit operable to initiate a rebuild of the RAID volume based on the received SMP command from the controller, and a Serial SCSI Protocol (SSP) initiator operable to generate SSP commands for performing the RAID rebuild based upon input from the control unit.
