scsi_device

- SCSI device structure

Synopsis

#include <sys/scsi/scsi.h>

Interface Level

Solaris DDI specific (Solaris DDI).

Description

The scsi_device structure stores common information about each SCSI logical unit, including pointers to areas that contain both generic and device specific information. There is one scsi_device structure for each logical unit attached to the system. The host adapter driver initializes part of this structure prior to probe(9E) and destroys this structure after a probe failure or successful detach(9E).

Structure Members

struct scsi_address        sd_address; /* Routing info. */
dev_info_t                 *sd_dev;    /* Cross-ref. to */
                                       /* dev_info_t */
kmutex_t                   sd_mutex;   /* Mutex for this dev. */
struct scsi_inquiry        *sd_inq;    /* scsi_inquiry data struc. */
struct scsi_extended_sense *sd_sense;  /* Optional request */
                                       /* sense buffer ptr */
caddr_t                    sd_private; /* Target drivers 
                                          private data */

sd_address contains the routing information that the target driver normally copies into a scsi_pkt(9S) structure using the collection of makecom(9F) functions. The SCSA library routines use this information to determine which host adapter, SCSI bus, and target/logical unit number (lun) a command is intended for. This structure is initialized by the host adapter driver.

sd_dev is a pointer to the corresponding dev_info structure. This pointer is initialized by the host adapter driver.

sd_mutex is a mutual exclusion lock for this device. It is used to serialize access to a device. The host adapter driver initializes this mutex. See mutex(9F).

sd_inq is initially NULL (zero). After executing scsi_probe(9F), this field contains the inquiry data associated with the particular device.

sd_sense is initially NULL (zero). If the target driver wants to use this field for storing REQUEST SENSE data, it should allocate an scsi_extended_sense(9S) buffer and set this field to the address of this buffer.

sd_private is reserved for the use of target drivers and should generally be used to point to target specific data structures.
