Usage: lsscsi   [--classic] [--device] [--generic] [--help] [--hosts]
        [--kname] [--list] [--long] [--protection] [--sysfsroot=PATH]
        [--transport] [--verbose] [--version] [<h:c:t:l>]
  where:
    --classic|-c      alternate output similar to 'cat /proc/scsi/scsi'
    --device|-d       show device node's major + minor numbers
    --generic|-g      show scsi generic device name
    --help|-h         this usage information
    --hosts|-H        lists scsi hosts rather than scsi devices
    --kname|-k        show kernel name instead of device node name
    --list|-L         additional information output one
                      attribute=value per line
    --long|-l         additional information output
    --protection|-p   show data integrity (protection) information
    --sysfsroot=PATH|-y PATH    set sysfs mount point to PATH (def: /sys)
    --transport|-t    transport information for target or, if '--hosts'
                      given, for initiator
    --verbose|-v      output path names where data is found
