# /usr/bin/rescan-scsi-bus.sh即可rescan SCSI设备 以下是rescan-scsi-bus.sh的说明 # /usr/bin/rescan-scsi-bus.sh --help
Usage: rescan-scsi-bus.sh [options] [host [host ...]]
Options:-a 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 scan for target device IDs 0--15 [default: 0--7]-c enables scanning of channels 0 1 [default: 0 / all detected ones]-m update multipath devices [default: disabled]-r enables removing of devices [default: disabled]-f flush failed multipath devices [default: disabled]-i issue a FibreChannel LIP reset [default: disabled]-u look for existing disks that have been remapped-s look for resized disks and reload associated multipath devices, if applicable
--alltargets: same as -a
--remove: same as -r
--flush: same as -f
--issue-lip: same as -i
--wide: same as -w
--multipath: same as -m
--forceremove: Remove stale devices (DANGEROUS)
--forcerescan: Remove and readd existing devices (DANGEROUS)
--nooptscan: dont stop looking for LUNs if 0 is not found
--color: use coloured prefixes OLD/NEW/DEL
--hostsLIST: Scan only host(s) in LIST
--channelsLIST: Scan only channel(s) in LIST
--idsLIST: Scan only target ID(s) in LIST
--lunsLIST: Scan only lun(s) in LIST
--sync/nosync: Issue a sync / no sync [default: sync if remove]
--attachpq3: Tell kernel to attach sg to LUN 0 that reports PQ3
--reportlun2: Tell kernel to try REPORT_LUN even on SCSI2 devices
--largelun: Tell kernel to support LUNs 7 even on SCSI2 devs
--sparselun: Tell kernel to support sparse LUN numbering
--update: same as -u
--resize: same as -sHost numbers may thus be specified either directly on cmd line (deprecated) oror with the --hostsLIST parameter (recommended).
