Claim 4:
5. The method for controlling startup of a hard disk drive system according to claim 4, wherein
in an OOB negotiation process of the link initialization negotiation, by setting the state of an SCSI application layer power state machine, controlling a motor of each hard disk drive in the hard drive group to enter a spinning state comprises:
performing a first OOB negotiation on the hard drive group;
after the first OOB negotiation ends, setting the state of the SCSI application layer power state machine as an Active state by means of the firmware in an SAS port control chip or an SAS port expansion chip; and
performing a second OOB negotiation on the hard drive group;
wherein the OOB negotiation may comprise:
sending a first COMINIT signal to the hard drive group to receive a second COMINIT signal returned by the hard drive group;
after receiving a second COMINIT signal returned by the hard drive group, sending a COMSAS signal to the hard drive group to receive a third COMINIT signal returned by the hard drive group; and
after receiving a third COMINIT signal returned by the hard drive group or after a preset time, sending a COMWAKE signal to the hard drive group.
