you can also get that information on the host side if they are using Powerpath (powermt display dev=all)
A noob question , need your help please .   In our environment requests are  like , "Add 1 TB to F drive" | "Expand D drive by  2 TB " . From the Clariion or Vmax that we manage I can only see Luns , how can I identify  what lun is mapped where  which one to expand   Is there anyway I can check which is the target Lun I should be expanding as (D/E/F drive ) dosen't make any sense to me cos i dont know .  Peace !
