SCSI_REPORT_LUN_SCAN(9)                   SCSI mid layer                  SCSI_REPORT_LUN_SCAN(9)



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
