The scsi_address(9S) structure provides transport and addressing information for each SCSI command that is allocated and transported by a target driver instance.
The scsi_address structure contains the following fields:
struct scsi_address { struct scsi_hba_tran *a_hba_tran; /* Transport vectors */ ushort_t a_target; /* Target identifier */ uchar_t a_lun; /* LUN on that target */ uchar_t a_sublun; /* Sub LUN on that LUN */ /* Not used */ };
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.
Identifies the SCSI target on the SCSI bus.
Identifies the SCSI logical unit on the SCSI target.
