I installed a 4GB Cisco module to replace a 2GB I am currently running.
However, I see it running at 2GB only and it won't go into 4GB mode/speed on the storage. Port one is connected directly to a storage unit.
Now, before I do this, I was wondering, could it be because all of my FC boards on the blades are only 2GB at the moment? Perhaps once I change one or all of the boards to 4GB, then the Cisco switch will go into 4GB mode?
