1.4.3.9 NOTIFY
The NOTIFY (ENABLE SPINUP) primitive is sent by a SAS INIT device or
expander device. When receiving the NOTIFY (ENABLE SPINUP) primitive in
the active wait state of SCSI power conditions, a drive enters the active state.
A NOTIFY primitive is sometime used as a substitute for an ALIGN primitive,
and it is sent by the initiator or expander at regular intervals.
A SAS TARG device with multiple SAS TARG ports treats the NOTIFY
(ENABLE SPINUP) primitives from all the SAS TARG ports equally (for
example, the NOTIFY (ENABLE SPINUP) primitive received through SAS
TARG port A is treated as the wakeup for the START STOP UNIT command
received through SAS TARG port B).
The NOTIFY (RESERVED 0), NOTIFY (RESERVED 1), and NOTIFY
(RESERVED 2) primitives are ignored by all devices.
1.4.3.10 OPEN_ACCEPT
The OPEN_ACCEPT primitive indicates the acceptance of a connection request.
The recipient of an OPEN frame must send the OPEN_ACCEPT primitive within
1 ms, when it can accept the connection request.
1.4.3.11 OPEN_REJECT
An OPEN_REJECT primitive indicates the rejection of a connection request.
Among the OPEN_REJECT primitives, there are those indicating that the
connection request cannot be continued (OPEN_REJECT abandon primitives)
and those indicating that the connection request can be retried (OPEN_REJECT
retry primitives).
The OPEN_REJECT primitives defined in Table 1.13 direct the recipients to
abandon the connection request.
