I hit this issue on latest tree RHEL-7.3-20160825.0 in my job https://beaker.engineering.redhat.com/recipes/3001418

Here is the package versions:
libhbalinux-1.0.17-2.el7.x86_64
libhbaapi-2.2.9-6.el7.x86_64
fcoe-utils-1.0.31-1.git5dfd3e4.el7.x86_64

This is related to bug 1321501 which has never been resolved. Haven't been able to run fcoeadm -i without error. 

libhbalinux-1.0.17-2.el7.x86_64
libhbaapi-2.2.9-6.el7.x86_64
fcoe-utils-1.0.30-3.git91c0c8c.el7.x86_64

No, they are convert. what I expected is error appeared after I updated the /etc/hba.conf, but I didn't see the error. After confirmed with the mmalik@, it is not BUG. It caused by the futile /etc/hba.conf on RHEL7.3. He will help investigate it and let me close it. Thanks for all your attention!
