When dealing with CLARiiON array, database backup would be taken at LUN level using Navisphere CLI(naviseccli) snapview that would allow to create a copy of LUN using snapshots. That's why it becomes highly imperative to have mapping of LUN to physical device and ASM diskgroup. I'll be covering on the script to have that kind of mapping using powerpath management utility and also a little bit on I/O.
