scsi_address Structure

The scsi_address(9S) structure provides transport and addressing information for each SCSI command allocated and transported by a target driver instance.

The scsi_address(9S) structure contains the following fields:

	
		scsi_hba_tran_t	*a_hba_tran;		/* HBA transport vectors */
 	u_short				 a_target;			/* Target on SCSI bus */
 	u_char				 a_lun;				/* Lun on that Target */

a_hba_tran is a pointer to the scsi_hba_tran(9S) structure, as allocated and initialized by the HBA driver. If SCSI_HBA_TRAN_CLONE was specified as the flag to scsi_hba_attach_setup(9F), a_hba_tran points to a copy of that structure.

a_target identifies the SCSI target on the SCSI bus.

a_lun identifies the SCSI logical unit on the SCSI target.
