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
running?
- 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?
Cheers,
Gina
