SAS Interface

1.4.3.9NOTIFY

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.
