Determine Logical Unit to drive letter

Currently we have 2 logical units that are the same size and I need to determine which one is drive letter D: to the OS. How can I go about determing this?

Re: Determine Logical Unit to drive letter

I assume this is a Windows server. You can check in device manager the location (Bus/target/LUN) of each disk. Then compare that to the LUN number on the storage device (which you don't say what kind it is).

If that's not clear enough, HPS reports generates very detailed information:

Re: Determine Logical Unit to drive letter

I checked that but the (Bus /target 4/LUN 0)is not the same of as the logical unit number of 1 for the Smart Array 6400 Controller to MSA30 shelves. This storage is not on a SAN.
