AIX SDD

I have sdd driver installed correctly but
when I run the command:

 datapath query adapter

No device file found
  

what does it mean.. it is not using vpath or whats wrong?

I think it just means no SDD devices were found.
Check your storage and SAN zoning.

I was confused.. excuse me for my unclear post.. I am using MPIO that is why sdd does not see any devices.. thanks a lot
