.SH "ARGUMENTS"
.PP
\fIstarget\fR
.RS 4
which target
.RE
.PP
\fIbflags\fR
.RS 4
Zero or a mix of BLIST_NOLUN, BLIST_REPORTLUN2, or BLIST_NOREPORTLUN
.RE

\fIrescan\fR
.RS 4
nonzero if we can skip code only needed on first scan
.RE
.SH "DESCRIPTION"
.PP
Fast scanning for modern (SCSI\-3) devices by sending a REPORT LUN command\&. Scan the resulting list of LUNs by calling scsi_probe_and_add_lun\&.
.PP
If BLINK_REPORTLUN2 is set, scan a target that supports more than 8 LUNs even if it\*(Aqs older than SCSI\-3\&. If BLIST_NOREPORTLUN is set, return 1 always\&. If BLIST_NOLUN is set, return 0 always\&. If starget\->no_report_luns is set, return 1 always\&.
.SH "RETURN"
.PP
0: scan completed (or no memory, so further scanning is futile) 1: could not scan with REPORT LUN
