multipath.conf

# This is a basic configuration file with some examples, for device mapper
# multipath.
#
# For a complete list of the default configuration values, run either
# multipath -t
# or
# multipathd show config
#
# For a list of configuration options with descriptions, see the multipath.conf
# man page

## By default, devices with vendor = "IBM" and product = "S/390.*" are
## blacklisted. To enable mulitpathing on these devies, uncomment the
## following lines.
#blacklist_exceptions {
#	device {
#		vendor	"IBM"
#		product	"S/390.*"
#	}
#}

## Use user friendly names, instead of using WWIDs as names.
defaults {
	user_friendly_names yes
	find_multipaths yes
}
##
## Here is an example of how to configure some standard options.
##
#
#defaults {
#	polling_interval 	10
#	path_selector		"round-robin 0"
#	path_grouping_policy	multibus
#	uid_attribute		ID_SERIAL
#	prio			alua
#	path_checker		readsector0
#	rr_min_io		100
#	max_fds			8192
#	rr_weight		priorities
#	failback		immediate
#	no_path_retry		fail
#	user_friendly_names	yes
#}

## The wwid line in the following blacklist section is shown as an example
## of how to blacklist devices by wwid.  The 2 devnode lines are the
## compiled in default blacklist. If you want to blacklist entire types
## of devices, such as all scsi devices, you should use a devnode line.
## However, if you want to blacklist specific devices, you should use
## a wwid line.  Since there is no guarantee that a specific device will
## not change names on reboot (from /dev/sda to /dev/sdb for example)
## devnode lines are not recommended for blacklisting specific devices.
