OPTIONS¶
Option are ordered by their long name. Those without a long name are ordered as if their single letter was a long name.
- -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]
- --channels=CLIST
- scan only channel(s) in CLIST
- --color
- use coloured prefixes OLD/NEW/DEL
- -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
- --ignore-rev
- ignore (firmware) revision change. This is the third text field (4 bytes long) in a standard INQUIRY response.
- -i, --issue-lip
- issue a FibreChannel LIP reset [default: disabled]
- -I SECS, --issue-lip-wait=SECS
- issue a FibreChannel LIP reset and then wait SECS seconds.
- -L NUM
- activates scanning for LUNs 0--NUM [default: 0]
- -l
- activates scanning for LUNs 0--7 [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
- --nosync
- do not issue a sync [default: sync if remove]
- -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
- issue a 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 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).
