The things that first come to my mind are:

- Is this system direct attached or in a switched fabric?

- You'll probably have the Navisphere Agent installed. Is it up and

- You'll probably have PowerPath installed, is it up and running? If yes,
  did you do a "powermt config", if yes, what does "powermt display
  dev=all" say?

Out of curiosity, which Clariion model is this?
