Abstract
Methods and structure are provided for enhancing zone configuration processes in a Serial Attached SCSI (SAS) architecture. The method includes embedding, at a SAS initiator, a ZONE UNLOCK request within a Serial Management Protocol (SMP) ZONE ACTIVATE command. The method also comprises transmitting the SMP ZONE ACTIVATE command to a SAS expander, and receiving, at the SAS expander, the SMP ZONE ACTIVATE command. Further, the method includes detecting, at the SAS expander, the ZONE UNLOCK request within the SMP ZONE ACTIVATE COMMAND. Additionally, the method includes copying, at the SAS expander, shadow SAS zoning data from a memory of the expander to current SAS zoning data at the memory of the expander responsive to acquiring the SMP ZONE ACTIVATE command. The method also comprises unlocking the SAS expander responsive to extracting the ZONE UNLOCK request from the SMP ZONE ACTIVATE command.
