SYNOPSIS

rescan-scsi-bus.sh [--alltargets] [--attachpq3] [-c] [--color] [---channels=CLIST] [-d] [--flush] [--forceremove] [--forcerescan] [--help] [--hosts=HLIST] [--ids=TLIST] [--issue-lip] [-l] [-L NUM] [--luns=LLIST] [--multipath] [--nooptscan] [--remove] [--removelun2] [--resize] [--sparselun] [--sync] [--update] [--version] [--wide] [HOST1 [HOST2 ...]]

OPTIONS

-a, --alltargets

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

--attachpq3

-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

--forcerescan

-h, --help

--hosts=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).
