    NAME

    multipath - Device mapper target autoconfig
     
    

    SYNOPSIS

    multipath [-v verbosity] [-d] [-h|-l|-ll|-f|-F] [-p failover|multibus|group_by_serial|group_by_prio|group_by_node_name] [device]  

    DESCRIPTION

    multipath is used to detect multiple paths to devices for fail-over or performance reasons and coalesces them  

    OPTIONS

    -v level
    verbosity, print all paths and multipaths
    0
    no output
    1
    print the created or updated multipath names only, for use to feed other tools like kpartx
    2 +
    print all info : detected paths, coalesced paths (ie multipaths) and device maps
    -h
    print usage text
    -d
    dry run, do not create or update devmaps
    -l
    show the current multipath topology from information fetched in sysfs and the device mapper
    -ll
    show the current multipath topology from all available information (sysfs, the device mapper, path checkers ...)
    -f
    flush a multipath device map specified as parameter, if unused
    -F
    flush all unused multipath device maps
    -p policy
    force maps to specified policy:
    failover
    1 path per priority group
    multibus
    all paths in 1 priority group
    group_by_serial
    1 priority group per serial
    group_by_prio
    1 priority group per priority value. Priorities are determined by callout programs specified as a global, per-controller or per-multipath option in the configuration file
    group_by_node_name
    1 priority group per target node name. Target node names are fetched in /sys/class/fc_transport/target*/node_name.
    device
    update only the devmap the path pointed by device is in. device is in the /dev/sdb (as shown by udev in the $DEVNAME variable) or major:minor format. device may alternatively be a multipath mapname
