have encounter one issue that we need to identify the lun mapped to which drive in windows 2003.
I have attached powerpath and t disk status from the host side.

C:\Documents and Settings\Administrator>powermt display dev=all

Logical device ID=60060160CCC9220066D55EC203E8DD11 [LUN 14]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP B, current=SP B       Array failover mode: 1
