OPTIONS

       -a, --alltargets
              scan all targets, not just currently existing [default: disabled]

       --attachpq3
              tell kernel to attach sg to LUN 0 that reports PQ=3

       -c     enables scanning of channels 0 1   [default: 0 / all detected ones]

       --color
              use coloured prefixes OLD/NEW/DEL

       --channels=CLIST
              scan only channel(s) in CLIST

       -d     enable debug                       [default: 0]

       -f, --flush
              flush failed multipath devices     [default: disabled]

       --forceremove
              remove and readd every device (DANGEROUS)

       --forcerescan
              rescan existing devices

       -h, --help
              print usage message then exit

       --hosts=HLIST
              scan only host(s) in HLIST

       --ids=TLIST
              scan only target ID(s) in TLIST

       -i, --issue-lip
              issue a FibreChannel LIP reset     [default: disabled]

       -l     activates scanning for LUNs 0--7   [default: 0]

       -L NUM activates scanning for LUNs 0--NUM [default: 0]

       --largelun
              tell kernel to support LUNs > 7 even on SCSI2 devs

       --luns=NLIST
              scan only lun(s) in NLIST

       -m, --multipath
              update multipath devices           [default: disabled]

       --nooptscan
              don't stop looking for LUNs is 0 is not found

       -r, --remove
              enables removing of devices        [default: disabled]

       --reportlun2
              tell kernel to try REPORT_LUN even on SCSI2 devices

       -s, --resize
              look for resized disks and reload associated multipath devices, if applicable

       --sparselun
              tell kernel to support sparse LUN numbering

       --sync, --nosync
              issue a sync / no sync [default: sync if remove]

       -u, --update
              look for existing disks that have been remapped

       -V, --version
              shows  version  string then exits. The version string is a numeric datestamp of the
              form YYYYMMDD.

       -w, --wide
              scan for target device IDs 0--15   [default: 0--7]

              Host numbers may thus be specified either directly on cmd line (deprecated)  or  or
              with the --hosts=LIST parameter (recommended).

       Arguments to options that end in LIST (e.g. TLIST) can have this form:
           A[-B][,C[-D]]...
       which is a comma separated list of single values and/or ranges (no spaces allowed).
