Looking at a new environment does anyone know how to query a Symmetrix (or Clariion) to determine the speeds of the physical drives in the system?

I know some of the part numbers off-hand, but for older (or brand new) systems it is hard to keep track of the exact part numbers. Does anyone know a query to confirm that a Seagate CUDA180 is a 7200k drive instead of having to hit Google and hope you can find a description match?

Yes I know you could go and check the PO, that is cheating, looking for a technical answer if there is one.

Thanks.
