Hi
Today on IRC we worked on this issue and I will try to summarized the results of our troubleshooting :
Current stable systemd rpm has a bug with device mapper which cause all device created on a fibrechannel to have wrong access right.
So the workaround is to replace systemd with the one on the testing repo.
But the testing release as also a bug with udev which rename network interface so that each new network interface is named renameX@interface.
We test some udev workaround unsucessfully. ( https://bugzilla.redhat.com/show_bug.cgi?id=907365 )
Now I think a patch on systemd testing rpm should fix the issue, waiting for it
