# scsi\_report\_lun\_scan(9)

Scan using SCSI REPORT LUN results

## NAME

scsi\_report\_lun\_scan - Scan using SCSI REPORT LUN results

## SYNOPSIS

**int scsi\_report\_lun\_scan(struct scsi\_target \*** *starget***, int** *bflags***, enum scsi\_scan\_mode** *rescan***);**

## ARGUMENTS

*starget*

which target

*bflags*

Zero or a mix of BLIST\_NOLUN, BLIST\_REPORTLUN2, or BLIST\_NOREPORTLUN

*rescan*

nonzero if we can skip code only needed on first scan

## DESCRIPTION

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.

If BLINK\_REPORTLUN2 is set, scan a target that supports more than 8 LUNs even if it's 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.

## RETURN

0: scan completed (or no memory, so further scanning is futile) 1: could not scan with REPORT LUN
