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.

0

scan completed (or no memory, so further scanning is futile)

1

could not scan with REPORT LUN
