Cause:
The fcoeadm tool was not properly sending VN2VN create requests to fcoemon.
Consequence:
Requested VN2VN mode FCoE interfaces would actually be created as fabric mode.
Fix:
fcoeadm was fixed to pass the proper command to fcoemon
Result:
VN2VN interface creation with fcoeadm works as expected

fcoe-utils-1.0.29-2.el7.x86_64 Just like in bug #1046226, could you retry with SELinux disabled and post any AVC messages you get, if applicable? retry with SELinux disabled. and still get the same issue. It seems like the option "-m vn2vn" does not work. it always use the Fabric mode to create the FCoE instance.

set it to blocker since vn2vn is the rhel 7.0 fcoe feature. we should support it via the fcoeadm. (In reply to Xiaowei Li from comment #7) > set it to blocker since vn2vn is the rhel 7.0 fcoe feature. we should > support it via the fcoeadm. As there is a workaround, I don't believe this meets the blocker criteria.

It's fixed. Move to VERIFIED.
