it is a difference between the end-of-line characters in the zfcp.conf
file - 0x0a (unix style) vs 0x0d 0x0a (DOS/Win style). Wasn't the
zfcp.conf file transferred from another system? I'll look why the
zfcpconf script doesn't understand both of them. And if you could file
a bug in http://bugzilla.redhat.com it would be great.
