Hello Ed,  after changing some options i suddenly saw, that the CTP cards are working now (no error message), sadly i dont know how or why. A SAN refresh is not an option for me, because i am just a student for my professor who got these switches from your company as a present and the project is solely based on these two switches. (Just a little testlab for students).  Regards Jens K.
So I got 2 DS4700M Switches and connected each other with a file-server. The transfer of files is working and i cant see any errors when i am copying files, but it still bothers me: What purpose does have the control processor card if the transfer of files is fine?  regards Jens K.
CTP State failed - fibre channel still works?
