Bug description:
SUMMARY:
Wrong path used when detecting multipath id
ANALYSE:
when multipath device path was not found via LUN wwn, os-brick would use device path like below:
/dev/disk/by-path/ip-192.168.3.52:3260-iscsi-
iqn.1992-04.com.emc:cx.apm00153906536.b5-lun-155
to detect multipath id via 'multipath -l <device path>'
but this cause error:
: can't get udev device
actually, we should use its real path like /dev/sdb, dev/sda to detect
the multipath id.
