.SH NAME
scsi_add_device \- creates new scsi device (lu) instance
.SH SYNOPSIS
.sp
\fB
.sp
struct scsi_device * scsi_add_device  (struct Scsi_Host * \fIshost\fB, unsigned int \fIchannel\fB, unsigned int \fIid\fB, unsigned int \fIlun\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIshost\fB\fR
pointer to scsi host instance
.TP
\fB\fIchannel\fB\fR
channel number (rarely other than 0)
.TP
\fB\fIid\fB\fR
target id number
.TP
\fB\fIlun\fB\fR
logical unit number
.SH "DESCRIPTION"
.PP
Returns pointer to new struct scsi_device instance or 
ERR_PTR(-ENODEV) (or some other bent pointer) if something is
wrong (e.g. no lu responds at given address)
.SH "NOTES"
.PP
This call is usually performed internally during a scsi
bus scan when a HBA is added (i.e. \fBscsi_add_host\fR). So it
should only be called if the HBA becomes aware of a new scsi
device (lu) after \fBscsi_add_host\fR has completed. If successful
this call we lead to \fBslave_alloc\fR and \fBslave_configure\fR callbacks
into the LLD.
