MULTIPATH(8) Linux Administrator's Manual MULTIPATH(8)NAME
multipath - Device mapper target autoconfig
SYNOPSIS
multipath [-v verbosity] [-d] [-h|-l|-ll|-f|-t|-F-B] [-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
-t print internal hardware table to stdout
-r force devmap reload
-B treat the bindings file as read only
-p policy
force new maps to use the 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-con-
troller 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.
Existing maps are not modified.
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
