(RAC) datafile -> physical disk link under ASM

Hello,

i would like to ask for help with following question. It is possible to find a direct link, between  datafile - physical disk/mountpoint under ASM ?
If yes, how.

In example, in following select:

NAME                      GROUP_NUMBER DISK_NUMBER MOUNT_STATUS          STATE                    PATH
------------------------- ------------ ----------- --------------------- ------------------------ ------------------------------
ASM_DATA1_000                        1           0 OPENED                NORMAL                   /dev/asm_disk1
ASM_DATA1_002                        1           1 OPENED                NORMAL                   /dev/asm_disk2
ASM_DATA2_001                        2           2 OPENED                NORMAL                   /dev/asm_disk3
ASM_DATA2_002                        2           3 OPENED                NORMAL                   /dev/asm_disk4

One would be able to link datafile and specific group, but as the file_name under v$datafile specification doesn't reflect the complete name shown in v$asm_disk one can't tell which exact disk/mountpoint is the datafile stored in, only group. And say we have hundreds of disk for one group. Then again, it is possible to deduce the link, if yes, how. Any feedback would be really appreciated.
