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