NAME - script for adding and removing SCSI devices without rebooting

SYNOPSIS [options] [host [host ...]]


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

       -d     enable debug                       [default: 0]

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

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

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

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

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

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

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

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

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

              rescan existing devices

              remove and readd every device (DANGEROUS)

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

              use coloured prefixes OLD/NEW/DEL

              scan only host(s) in LIST

              scan only channel(s) in LIST

              scan only target ID(s) in LIST

              scan only lun(s) in LIST

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

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

              tell kernel to try REPORT_LUN even on SCSI2 devices

              tell kernel to support LUNs > 7 even on SCSI2 devs

              tell kernel to support sparse LUN numbering

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

       LIST: A[-B][,C[-D]]... is a comma separated list of single values and  ranges  (No  spaces
