We are still seeing some errors. Here are the results for 15.04 running the upstream 4.1.0-rc8-next built 2015-06-22. I’m still seeing some error messages, though multipath is at least able to recognize the vFC disks.

The [current] illegal request is still showing up. 2. “failure for create/reload map” messages still appear.
