SCSI_PROBE_AND_ADD_L(9) SCSI mid layer SCSI_PROBE_AND_ADD_L(9)NAME
scsi_probe_and_add_lun - probe a LUN, if a LUN is found add it
int scsi_probe_and_add_lun(struct scsi_target * starget, uint lun, int * bflagsp, struct scsi_device ** sdevp, int rescan,
void * hostdata);
pointer to target device structure
LUN of target device
store bflags here if not NULL
probe the LUN corresponding to this scsi_device
if nonzero skip some code only needed on first scan
passed to scsi_alloc_sdev
Call scsi_probe_lun, if a LUN with an attached device is found, allocate and set it up by calling scsi_add_lun.
could not allocate or setup a scsi_device
target responded, but no device is attached at the LUN
a new scsi_device was allocated and initialized

scsi_device(9S) Data Structures for Drivers scsi_device(9S)NAME
scsi_device - SCSI device structure
Solaris DDI specific (Solaris DDI).
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).
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
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.
