Hi Jens,

The dm device referred to in my e-mail is a dm-mpath device created by test
srp/002. All parameters of that device are under control of that test script.
From the srp/002 test script:

DESCRIPTION="File I/O on top of multipath concurrently with logout and login (mq)"

From srp/multipath.conf:

defaults {
	find_multipaths		no
	user_friendly_names	yes
	queue_without_daemon	no
}

devices {
	device {
		vendor		"LIO-ORG|SCST_BIO|FUSIONIO"
		product		".*"
		features	"1 queue_if_no_path"
		path_checker	tur
	}
}

Bart.
