NAME

       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  ini-
       tializes 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 information */
       dev_info_t		  *sd_dev;    /* Cross-reference */
					      /* to our dev_info_t */
       kmutex_t 		  sd_mutex;   /* Mutex for this device */
       struct scsi_inquiry	  *sd_inq;    /* scsi_inquiry data structure */
       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.
