4) When, in contradiction to the fact that the physical link rate is 1.5 Gbps, the
CONNECTION RATE field in a received OPEN frame is 3.0G, the drive
sends the OPEN_REJECT (CONNECTION RATE NOT SUPPORTED)
primitive.
5) A dual port drive may process requests from up to four INITs at a time for
each port. When a dual port drive holds commands from four INITs for one
of its ports, and if it receives a connection request from a fifth INIT through
the same port, the drive sends the OPEN_REJECT (RETRY) primitive.
6) When the drive cannot receive an SSP frame temporarily due to the recovery
processing of an internal drive error, the drive sends the OPEN_REJECT
(RETRY) primitive.
7) When the SAS address of a drive does not match the DESTINATION SAS
ADDRESS field in a received OPEN frame, the drive sends the
OPEN_REJECT (WRONG DESTINATION) primitive.
