Bug Description

During a Xenial installation, the multipath devices from an IBM IPR controller were not discovered, as the block devices lacked the SCSI_IDENT_* udev properties.

The fix was to simply reload udev rules and re-add the devices w/ update-dev; and the devices were correctly multipathed.

Adding a patch to do that in /bin/disk-detect.
