Udev may fail to create the expected symbolic links in /dev/disk/by-vdev on systems with the device-mapper-multipath-0.4.9-100.el6 package installed. This affects RHEL 6.9 and possibly other downstream distributions. That version of the multipath command may incorrectly list a drive state as "unkown" instead of "running". The issue was introduced in the patch for https://bugzilla.redhat.com/show_bug.cgi?id=1401769 The vdev_id udev helper uses the state reported by "multipath -l" to detect an online component disk of a multipath device in order to resolve its physical slot and enclosure. Changing the command invocation to "multipath -ll" works around the above issue by causing multipath to consult additional sources of information to determine the drive state.
