Hi all,
Here's a shell script that I've been using to replace the features of
fcconf that I used frequently. One nice thing about it is that it doesn't
require root access except to just view status. It should work for all HBAs.
Let me know what you think. Try it out. We can name it anything,
but for now I've called it 'fcc'. (I guess Federick Community
College won't mind :-) ).
Joe
