1 The locate feature is not supported by all target enclosures. Refer to your enclosure's documentation to determine whether the locate feature is supported on your device.
2 The external wide port address of the SAS HBA is not a fixed address. The auto-configuration feature dynamically assigns the SAS address based on the port linkup sequence and port number. Because the address assignment is based on the port link sequence, when you perform a DC/AC power cycle or move a cable, the port's SAS address might change, resulting in the original LUN mapping getting changed.
